A resupply mission to the International Space Station (ISS) has made record time, traveling from Earth to the space station in just three hours and 21 minutes. The Soyuz-2.1a carrier rocket with a Progress MS-11 cargo spaceship was launched from the Russian space Agency Roscosmos’ Baikonur Cosmodrome in Kazakhstan at 7:01 a.m. on Thursday, April 4.
The super speedy travel time was possible due to a change in how resupply craft approach the ISS. Before, the resupply craft would have to orbit around the Earth dozens of times in order to catch up with the speed of the space station. But now there is a “fast-track” launch which allows the craft to catch up to the station in just two rotations. The resupply craft is launched less than a minute before the space station passes overhead of the launch site, so the craft can catch up to the station more quickly.
Nick Hague, an astronaut aboard the ISS, tweeted his approval of the achievement. “The progress resupply vehicle made record timing as it launched and docked to the station in under three and a half hours,” he said. “Pretty impressive!” The people of Twitter were impressed too. “…quicker than JFK-LAX!” one person commented.
The docking of the Progress resupply craft was welcomed by Flight Engineer Christina Koch for another reason as well: “Glad to have another 3.7 tons of supplies and science joining us!” she shared on Twitter.
The ISS requires regular resupply, with the six astronauts aboard (three from NASA, two from Russian Roscosmos, and one from Canadian CSA) needing deliveries of food including occasional treats like fresh fruits and ice cream. The resupply craft also carry scientific equipment, computer components, and spacewalk equipment.
The organizers of ISS will surely be particularly attuned to the availability of spacewalk equipment after public outcry when the first all-female spacewalk was cancelled last month due to a lack of correctly sized spacesuits being available.

Northern lights are one of the biggest draws to visit Iceland and they are also one of the most exclusive and unpredictable attractions Iceland has.
They are also known as Aurora, Polar Lights and they can be seen in the high-latitude regions (Arctic and Antartic). The best season to see the northern light in Iceland is from September to mid-April because of the full dark nights in these months.
Hunting the Northern lights can be done in a variety of ways, but each method seeks for the same result: a magical, ethereal display that will last in your memories for life.

An eclipse is a natural phenomenon like a sunset and a sunrise. The Earth and its moon are in constant motion. Thus, they are bound to cross over each other at some point in time.
What Is an Eclipse?
An eclipse occurs when a star or planet is temporarily obscured, either by passing into the shadow of another astronomical object or having another object pass between it and the viewer.
What Is a Lunar Eclipse?
When the earth is in between its moon and the sun, a lunar eclipse occurs.
Can a Lunar Eclipse (Chandra Grahan) Harm Your Baby in the Womb?
It’s believed that an eclipse has bad effects on pregnant women. However, there is no scientific proof to support this belief.
How Age-Old Beliefs Affect Pregnancy
If you avoid eating and drinking during an eclipse, it can cause dehydration and have adverse effects on you and your baby. This can also increase your blood pressure, affecting your baby’s health.
If you notice these symptoms, consult a doctor immediately.
- Dizzy spells
- Severe headache
What Is a Solar Eclipse?
When the Earth’s moon comes in between it and the sun, it’s called a solar eclipse.
Can a Solar Eclipse (Surya Grahan) Harm Your Foetus?
It’s believed that gazing at the sky during an eclipse can cause miscarriage or deformities. However, there are no studies that support this.
Solar/Lunar Eclipses in 2020
In 2020, we will be witnessing two Solar eclipses (Surya Grahan), and four Lunar eclipses (Chandra Grahan). The first solar eclipses of the year will be annular while the second will be total. We can witness these on June 21 and December 14 respectively. This year, all the lunar eclipses will be penumbral (Chaya Chandra Grahan) and will be occurring on January, June, July and November 2020.
Fun fact – this year is the second time in the 21st century that we will be witnessing all penumbral lunar eclipses.
|Date||Type of Eclipse|
|10-11 Jan||Lunar Eclipse (Penumbral)|
|5-6 Jun||Lunar Eclipse (Penumbral)|
|21-Jun||Solar Eclipse (Annular)|
|29-30 Nov||Lunar Eclipse (Penumbral)|
Myth vs Fact
We do the myth-busting for you and tell you the facts here:
1. Myth: Stay Indoors and Don’t Look at the Sun
Fact: Turns out, the elders were right with this one! Pregnant women shouldn’t look at an eclipse with naked eyes because:
- The sun’s radiation during an eclipse is harmful.
- It can affect the exposure that your retina will have to the intense visible light of the sun.
- This can cause retinal burns and damage to the light-sensitive rods and cone cells.
2. Myth: Don’t Cook, Eat or Drink During an Eclipse
Fact: This is true. The sun rays can’t reach the Earth during an eclipse, causing a drop in the temperature. This causes bacteria, microbes, and harmful germs to multiply.
Neither solar eclipse nor lunar eclipse have any effect on your pregnancy. Whether to follow the generation-old beliefs and customs is your choice.

As I stood at Pittock Mansion last night to photograph the Blue Moon rising near Mt. Hood I was entertained by a variety of people questioning the origin of the term “blue moon”. At one point a gal walked away from her group in a bit of a huff declaring that “it’s stupid, it’s NOT blue”. Yeah, she’s right. Our local weather guy explained that the second full moon in a month is properly called a blue moon. I carried that information with me to the Mansion and offered it up when asked if I knew why it was called a blue moon. I like to think that I sounded scholarly.. at least I did not hesitate to offer the explanation. Everyone seemed content. Why not?
I just googled “blue moon” and looked at the definition or origin in Wikipedia. They say that the third full moon of a season with four full moons is referred to a blue moon. Historically, a “season” had four full moons. To get two of four full moons in a single month is a fairly rare event but does not help to explain how it got the name in the first place. Our use of the term “once in a blue moon” seems to support the notion of rarity and also reinforces that the term “blue moon” is something real and well known. Go figure. Anyway, it was entertaining to listen to people speculate how it came to be that the event we were watching was called “blue moon”.
For me, the event was special because of it’s occurrence next to Mt. Hood so close to sundown. The smoke made for disappointing results photographically but I figured it was a great way to spend the evening and to think about Neil Armstrong and the first step onto the moon. I’m confident that he was not bothered by smoke or haze as he gazed at earth from the moon. What a thrill he must have felt go up his spine as he came off the ladder. I know that my skin tingled as I watched him step down. Now, that step is a true rare event.


By Alan M. MacRobert
By the time you set out into the night with a telescope, you should know the constellations well enough to find your way around the sky.
An all-sky constellation map (such as the evening sky map in each issue of Australian Sky & Telescope) will get you started. So will a planisphere. Think of your all-sky map as like a map of the world; if you don't know where Japan or England are, you need to learn.
But once you've found England on a world map, it's not much good for getting you to a particular street address in Tunbridge Wells. In addition to a wide-scale constellation map, a telescope user needs a more detailed, magnified sky atlas in order to locate specific points of interest.
The standard atlas for serious telescope users is Sky Atlas 2000.0 by Wil Tirion and Roger W. Sinnott. It covers the celestial sphere in 26 big charts that plot a total of 81,000 stars (to as faint as magnitude 8.5) and 2,700 other objects.
Such maps may look terribly complex at first. But step back for a minute, squint your eyes, and look at only the brighter stars. These form the same, familiar constellation patterns as are on your naked-eye all-sky map.
Directions and Distances
Suppose, for instance, you've learned Gemini as it's drawn on the Australian Sky & Telescope charts, where the stars are connected to form two stick figures holding hands. The same stars of Gemini appear on Chart 5 of Sky Atlas 2000.0 — but at a much larger scale and almost lost in a wealth of detail, as shown above. To keep the familiar naked-eye patterns in perspective, some people draw in the constellation stick figures with a pencil, as we've done here.
Directions on a sky map take a little getting used to. East is left of north on a sky map, not to the right like on a map of the ground. The reason is simple: You look down at the ground but up at the sky. (If you looked up through the bottom of a land map of, say, Australia — as if you were at the centre of a transparent Earth — it too would have east left when north was up.)
One trick for keeping east and west straight on a celestial map is remembering that right ascension increases to the east. If hours of right ascension are printed on the map's top or bottom, they'll set you straight.
The next step is to learn the map's scale. You have to know how much of the scene on paper appears in your finderscope's eyepiece before you can compare the map to what you see! As a rough guideline, a typical finderscope shows a field 5° wide, and a typical 50x telescope eyepiece shows a field 1° across. To see how big these sizes are on your star-atlas map, compare with the degree scale (the declination scale) along the map’s left and right edges.
Knowing the size of your finderscope’s field, and your lowest-power eyepiece field, is so important that you should make an effort to get it right. To determine the size of your finderscope’s field, locate two stars at night that just fit into its edges. Then see how many degrees apart these stars are on the map, by referring to the scale of degrees along the sides.
Now do the same to find the field diameter of the main telescope’s lowest-power eyepiece. It may be hard to identify a good star pair on your map to measure a field so small. So here’s another way. Aim at any star in the general area of the celestial equator — in Orion’s Belt, for example, or the Circlet of Pisces, or Procyon, Spica, or Altair. Centre the star. Then turn off the telescope’s clock drive (if any) and time how long the star takes to drift from the center of the field to the edge. The time in seconds, divided by 120, equals the field diameter in degrees.
Next, using the scale on the margin of the charts, make little rings out of wire — or draw circles on clear plastic — corresponding to your field sizes. By sliding these circles across the charts, you can see exactly what star patterns will pass through your field of view when you sweep across the sky.
Beginners are always surprised at how tiny the view really is. Keep these little tools with the charts; you'll need them whenever you observe.
Now we're ready to go on our first deep-sky hunt.

The Universe is all the matter, energy, and space that exists, and the observable universe is the part that we can see. While there are still great mysteries about how it all began and evolved, we are living in an age of rapid cosmic discovery. Astrophysicists use observations from telescopes on the ground and in space, spacecraft return data from the outer reaches of our solar system, models based on the mathematical laws of physics reveal the structure and history of the universe and our place in it. These simulations, videos, and essays, cover the formation, evolution, and properties of stars, planets, galaxies, and the universe.


Global One (G1)— Five different types of potentially harmful bacteria have been found aboard the International Space Station.
A recent NASA report said there is “79% probability that they may potentially cause disease.”
The NASA researchers who discovered them also fear the Enterobacter strains may be drug-resistant.
Three of the strains have reportedly caused illness in newborn babies.
However, the report also stresses none of the strains pose a threat to astronauts.
The research team says since “human immune systems are especially stressed while in space,” they will continue to monitor the bacteria.
The bacteria may even be helpful in the long term.
One of the researchers says, “Understanding how microbial life grows in a closed environment like the ISS will help us be better prepared for the health concerns that come with space travel.”
He continued, “The dream of human exploration through space won’t be possible without understanding the microbial world around us.”


La Cité du design launches three designers into the stars
The Cité du design Saint-Etienne, in association with the Institut Français (French Institute, the cultural department of the French Embassy), launched three designers “up to the stars” with an exhibition at the Dubai Design Week 2020 on the theme of space exploration and design.
The exhibition explores the frontiers between engineering and artistic practices with the projects of young designers, disseminating thus French design internationally.
The showcase consists of three projects:
“UNE VIE SUR MARS”, by Anthony Vacter, designer and a graduate of the Saint Etienne Higher School of Art and Design. This design fiction project in the form of 3d printed objects, proposes a scenario of life in space in 2050, after an ecological disaster on earth.
“TEASING NEW WEATHER TV” by Simone Fehlinger, designer and researcher at the Cité du design. In the context of the launch of the Hope probe of the Emirates Mars mission, which aims to study the weather conditions on Mars, the installation shows the relationship between design, architecture, space exploration, meteorological imagery and current visual and material culture.
“L’ETOILE” by LUX, a design studio composed of the creative duo, Simon Chevalier and Lucile Cassassolles. Humanity has always been fascinated by the stars, which have inspired science fiction, clairvoyance and astronomy. The large-scale 3D installation pays homage to the stars that have provided a discreet backdrop to the world since the beginning of time, when man first looked up at the night sky in wonder.

Our solar system officially has eight planets and one star: the Sun. The discovery of an object larger than Pluto in 2005 rekindled the debate over whether such objects, belonging to the Kuiper Belt – a collection of icy bodies located beyond Neptune – should be called planets. Pluto and other large members of the Kuiper Belt are now considered “dwarf planets.”

Life in a tourist town.
Yoo Jian by Kim Youngjun for W Korea Mar 2014


In a brand new examine that simulated the cruel ionising radiation on Mars, researchers discovered that historic micro organism may survive near the floor of the crimson planet for much longer than beforehand assumed. This implies that scientists needs to be looking out for historic micro organism and micro organism stays when the primary samples from Mars come again to Earth.
These findings open up the likelihood that if life ever advanced on Mars, we’d be capable of detect its organic stays in future missions, like EcoMars (Rosalind Franklin rover) and the Mars Life Explorer, which is able to drill two metres beneath the planet’s floor to search for life.
Also, the truth that sure strains of micro organism can survive Mars’ harsh surroundings means astronauts and house vacationers may by accident contaminate Mars with the micro organism they create together with them.
Simulating harsh circumstances on Mars
Mars has a particularly harsh surroundings which by all means needs to be inhospitable to life. The planet is arid and temperatures common minus 63 levels at its mid-latitudes. To make issues worse, the planet can also be continuously blitzed by intense galactic radiation and photo voltaic protons.
“Our model organisms serve as proxies for both forward contamination of Mars, as well as backward contamination of Earth, both of which should be avoided,” stated Michael Daly, who led the examine revealed within the journal Astrobiology. Daly is a professor of pathology on the Uniformed Services University of the Health Sciences (USU) and a member of the National Academies’ Committee on Planetary Protection.
“We concluded that terrestrial contamination on Mars would essentially be permanent — over timeframes of thousands of years. This could complicate scientific efforts to look for Martian life. Likewise, if microbes evolved on Mars, they could be capable of surviving until the present day. That means returning Mars samples could contaminate Earth,” added Brian Hoffman of Northwestern University. Hoffman is a senior co-author of the examine.
To examine whether or not life may survive within the harsh circumstances of Mars, Daly, Hoffman and the remainder of the analysis workforce first established the ionising radiation survival limits of microbial life. After that, they uncovered six completely different terrestrial micro organism and fungi to circumstances just like Mars’ floor. They did this by freezing them and hitting them with gamma rays and protons.
Life on Mars
Based on these simulation exams, the researchers concluded that some terrestrial microorganisms may be capable of survive on Mars over tons of of thousands and thousands of years. One significantly sturdy microbe, known as Deinococcus radiodurans, appeared significantly well-suited to dwelling on the crimson planet. During the experiment, this bacterium survived huge quantities of radiation whereas frozen.
The researchers attribute this spectacular hardiness of the bacterium to its genomic construction. Deinococcus radiodurans’s chromosomes and plasmids are linked collectively, which retains them in excellent alignment and prepared for restore after intense radiation.
This implies that if the same microbe advanced on Mars when the planet nonetheless had water, a few of its remnants may nonetheless be dormant underneath the Martian floor.

The northern light also known as the aurora borealis is a colorful band of light that dances in the dark night sky in Alaska. The Northern Lights have occurred since the dawn of our planet. Dinosaurs walked under them, just as we do today. They are a constant of our world—always there, even when it’s too bright for us to see them. The light show we see from the ground is caused by electrically charged particles from space entering the Earth’s upper atmosphere at a very high speed, what a wonderful world we have.


India proved sky is not the limit
India has achieved a historic milestone by successfully landing on the South Pole of the lunar surface, marking it as the first country to do so. Prime Minister Modi extended his congratulations to the Indian populace and the dedicated space scientists responsible for this remarkable feat.
The success of Chandrayaan-3's mission hinged significantly on the last 15 to 20 minutes, as the Vikram lander made its crucial descent for a gentle landing. People across India and around the globe are offering prayers for the successful touchdown of Chandrayaan-3.
Given the history of India's second lunar mission, which failed during the last 20 minutes before landing, ISRO was extra-cautious this time in the process. Due to high risk to the spacecraft minutes before moon landing, the duration is dubbed by many as "20 or 17 minutes of terror"
"Dreamt on Earth, achieved it on Moon’, says PM Modi"
India creates history with successful landing on lunar South Pole
The primary goal of the Chandrayaan 3 mission remains consistent with its predecessor: showcasing the ability to successfully land on and operate on the Moon. The lander and rover are equipped with diverse scientific instruments, encompassing a Langmuir probe intended to gauge alterations in plasma density close to the lunar surface, a seismometer, and a NASA-supplied laser retro-reflector array. Additionally, the rover is outfitted with an autonomous Alpha Particle X-ray spectrometer and a Laser Induced Breakdown Spectroscope (LIBS) for individual analysis.
Congratulations to India for their remarkable achievement in successfully landing on the moon! This accomplishment is a testament to their dedication, innovation, and scientific prowess. A giant leap that inspires the world and opens new frontiers of exploration. Well done! 🌕🚀 #MoonLandingSuccess #ProudMoment

Aiming for the stars
Portugal’s starlight tourism destination, Dark Sky Alqueva, draws stargazers from across the planet for extraordinary night-time experiences
“An old whitewashed primary school in a Portuguese village is our gateway to the heavens,” says Apolónia Rodrigues, who, in 2007, founded Dark Sky Alqueva, a protected reserve that is the world’s first certified “Starlight Tourism Destination”.
“Since 2015, it has been our headquarters and observatory,” she says. Located in Cumeada, two hours’ drive east of Lisbon in the Alentejo region, the Dark Sky Alqueva Official Observatory is the centre of Portugal’s growing night sky tourism industry. “There is no better place in Portugal to stargaze. As this is a rural area, very little unnatural light exists. Having grown up in a city, when I first saw the stars here I couldn’t believe my eyes.”
The journey to create Dark Sky Alqueva was not always straightforward, but friends and family helped Apolónia make her vision a reality. “So many people were willing to help. When we encountered a difficulty, I looked to the galaxies above and thought, ‘We have something magnificent here. A sea of stars that can be seen with the naked eye’.”
Apolónia’s passion made it worthwhile, as in 2011 the organisation was awarded the inaugural Starlight Tourism Destination certification by the Starlight Foundation. Supported by UNESCO and the UN’s World Tourism Organisation, this strictly regulated certification gave Dark Sky Alqueva worldwide recognition, with stargazers coming from across the globe. “Our objective is to inspire people with the extraordinary things happening above us,” says Apolónia. “You can ask our guides – cosmologists, astrophysicists, astronomers and astrophotographers – absolutely anything.”
Dark Sky Alqueva offers a network of accommodation to choose from and organises unique activities, such as the popular blind wine-tasting in the darkness – “creating a new connection between the mind and senses” – and astrophotography workshops with the reputed astrophotographer Miguel Claro. Night walks can be arranged and there is also night canoeing.
Nearly 15 years on, Dark Sky Alqueva still has the same mission, but it has since won in numerous categories at the World Travel Awards for three years in a row from 2019, winning the World’s Responsible Tourism Award 2021, among others.
“My objective has always been to demonstrate our individuality but in a sustainable way,” says Apolónia. “We bring value to the local community by providing visitors with something astonishing – the stargazing experience of a lifetime.”


Active Explorers Richmond Celebrate Matariki with a hangi
Active Explorers Richmond recently celebrated Matariki. One of their whanau offered to put down a hāngi for the celebration and the families came to the center in the evening to share the hāngi kai and the variety of foods they had brought along.
The children, having prepared weeks in advance, showed their families the wonderful stars and lanterns they had made to celebrate Matariki. They also showed them the wall display of Te Rā, Papatūānuku, and Ranginui. They ended their celebrations by exploring the night sky with glow sticks.

Also known as the father of Physics , this
was the man who created a new subject (Physics) out
of the basic sciences. He was very engrossed in his
studies. He used to study for 24 hours continuously.
He had high observation powers which helped him discover
few of the most importan concepts in Science (such
as gravity).Newton discovered how the universe is
held together through his theory of gravitation. He
discovered the secrets of light and colour. He invented
a branch of mathematics, calculus, also invented independently
by Gottfried Leibniz, a German mathematician . Newton
made these three discoveries within 18 months from
1665 to 1667.
The theories of motion and gravitation.
Newton said the concept of a universal force came to him
while he was alone in the country. He had been forced to
flee there because of the outbreak of bubonic plague in
the city of Cambridge. During this time, Newton suddenly
realized that one and the same force pulls an object to
earth and keeps the moon in its orbit. He found that the
force of universal gravitation makes every pair of bodies
in the universe attract each other. The force depends on
(1) the amount of matter in the bodies being attracted and
(2) the distance between the bodies. The force by which
the earth attracts or pulls a large rock is greater than
the pull on a small pebble because the rock contains more
matter. The earth's pull is called the weight of the body.
With this theory, Newton explained why a rock weighs more
than a pebble.
He also proved that many types of motion are due to one
kind of force. He showed that the gravitational force of
the sun keeps the planets in their orbits, just as the gravitational
force of the earth attracts the moon. The falling of objects
on earth seems different from the motion of the moon because
the objects fall straight down to the earth, while the moon
moves approximately in a circle around the earth. Newton
showed that the moon falls just like an object on earth.
If the moon did not fall constantly toward the earth, it
would move in a straight line and fly off at a tangent to
its orbit. Newton calculated how much the moon falls in
each second and found the distance is 1/3600 of the distance
an object on earth falls in a second. The moon is 60 times
as far from the earth's centre as such an object. Consequently,
the force of the earth on an object 60 times as far away
as another object is 1/3600.


Light travels at approximately 300,000 km per second. This website functions as a day calendar, showing the objects that a beam of light might pass by, when travelling from the sun, in a straight line, for one year (cats not included).
Our light particles have now travelled for a Julian year (365.25 days) and are not even close to reaching the nearest star. The Crab supernova remnant is about 4,000 years away; the Milky Way Galaxy would take 150,000 years to cross; the Andromeda Galaxy is 2.3 million light-years away. Light will have to travel for another 28 billion years to reach the edge of the visible universe.

For the 75 female students at Marian Middle School, attending a screening of Hidden Figures was likely more than just a field trip.
The film follows the true story of three female mathematicians—Katherine G. Johnson, Dorothy Vaughan, and Mary Jackson—who were instrumental in NASA’s successful effort to put astronaut John Glenn into orbit in 1962…Click here to continue reading.


Planet Mars is back in the news this weekend: NASA’s Phoenix spacecraft will attempt one of the most dangerous landings ever tried. The lander will attempt to set down in Mars north polar region after negotiating a perilous 15-minute entry into the Martian atmosphere.
If Phoenix survives the first seven minutes of fierce buffeting and heating (to thousands of degrees), it will then rely on a parachute and pulsing retrorockets to touch down.
Phoenix is equipped with a miniature backhoe and a set of sophisticated, automated laboratories that will analyze the soil and permafrost that Phoenix hopes to scoop up. Landing signals are expected around 4:53 PDT today…
[Update] Phoenix landed successfully at 4:53 PM PDT.


Academic City Students Visit The Planetarium Center Ghana
The Planetarium Science Center Ghana was founded by Dr. Jacob Ashong and stands as the first privately built digital planetarium in the country and in West Africa. It aims to promote practical STEM learning through initiatives such as shows, live astronomy telescope viewings and STEM workshops for students. For Business Administration Faculty, Stuart Gold, taking Academic City’s students to the planetarium was not only to introduce them to the idea of a locally based science education center but also to introduce them to space science and astronomy.
Stuart Gold, Business Administration faculty, introduces students to the planetarium
“In [the Fundamentals of Innovation and Entrepreneurship (FIE) course], we try to open the students' minds to different areas of interest and to broaden their outlook,” Mr. Gold said. “The Ghana Planetarium with its hemispherical projection dome offers a unique local perspective on our universe. With space exploration being a major hi-tech industry, currently worth $350 billion per year and growing to an estimated $30 trillion in thirty years, it is an industry with which they are likely to have some involvement in their future careers,” he added.
Last year, Academic City college, in collaboration with NIIT Ghana, and Vista Ghana, donated $12,000 to the planetarium, which was in dire need of funding support. Academic City remains committed to contributing to and promoting science literacy and STEM education in Ghana and in Africa.

NASA duo shares lessons learned and best practices from the launch of the current Mars 2020 mission to help leaders and teams “Sustain Awesome.”
Complex, multi-year projects like the Mars 2020 mission have their own unique challenges, even when they aren’t forced to launch during a global pandemic. A mission ten years in the making, Mars 2020 was plunged into uncertainty at a crucial juncture when NASA’s Jet Propulsion Laboratory team of 6,000+ was forced to operate remotely. Remarkably, the mission managed to achieve all original assembly and launch timelines. On February 18th, 2021, the Mars rover Perseverance and the robotic helicopter Ingenuity landed safely on the red planet.
Chief Engineer for the mission, Dr. Adam Steltzner shares his leadership insights with a focus on how organizations can ensure they are providing the right structure and foundation for complex projects and what leaders can do to nurture and support teams to produce their very best work. As the mission’s Lead for Planetary Protection, Dr. Moogega Cooper (“Dr. Moo”) explores the team’s incredibly broad range of skills and personalities and the innovative culture of “Perseverance” and “Ingenuity” that sustained mission success.
The duo’s energy and enthusiasm—for space exploration, science, and the power of teams—are contagious. Whether talking about NASA’s successful reinvention and culture of innovation, the importance of STEM careers, the search for life beyond our planet or the future of space tourism, this Keppler-exclusive duo acts as a powerful catalyst, inspiring teams to “to dare greatly, succeed mightily, and sustain awesome.”

Supermoon + Blood Moon + Lunar Eclipse (+ cool moon pics)
Here are some pictures I took during the Supermoon-Blood moon-lunar eclipse phenomenon of September 27, 2015.
I got there halfway into it, as the moon was already red. From then on, the circle of its usual white brilliance crept back over the moon. Here are some of the more interesting/cool shots I got 🙂
The sun shall be turned into darkness, and the moon into blood, before the coming of the great and awesome day of the Lord. And it shall come to pass that whoever calls on the name of the Lord shall be saved.
~ Joel 2:31-32a ~


This Is not a drill, Washington, D.C. ( NewsWatch33) – NASA has confirmed that the Earth will experience 15 days of total darkness which starts between November 15 and 29, 2016. The event, according to NASA, has been waiting for this pronominal event to happen.
Astronomers from NASA have indicated that the world will remain in complete darkness starting Sunday, November 15, 2016 at 3:00 am and will end on Monday, November 30, 2016 at 4:45 pm.According to officials, (the November blackout will be caused by an astronomical event between Venus and Jupiter).
Charles Bolden, who was appointed to the head of NASA by ‘president’ Obama, issued a 1000 page document explaining the event to the White House.
The claims in the report are utter nonsense. NASA has certainly not confirmed any such event. In fact, the report is just the latest version of a silly hoax that has been published over and over again in various guises since at least 2012. From time to time, another spammy, clickbait website will publish a new version of the hoax in a rather lame effort to attract more visitors.


Abstract: P-channel charge-coupled devices (CCDs) made from N-type silicon wafers were originally developed for ground-based optical and near-infrared telescopes. The thick depletion layer of these CCDs provides the significant advantage of high quantum efficiency (QE) for hard X-rays. On the other hand, high QE for soft X-rays is obtained with back-illuminated (BI) and fully depleted CCDs in which only a thin dead layer exists on the surface of incidence. Thus, P-channel BI CCDs can be applicable as superior wide band X-ray detectors. We have developed such a device specifically for the Soft X-ray Imager (SXI) on board the X-ray astronomy satellite ASTRO-H, scheduled to be launched in 2014. We previously reported that the depletion layers of our CCDs, a prototype of SXI-CCDs, have a thickness of more than View the MathML source. In this paper, we report a novel soft X-ray response of P-channel BI CCDs. First, we irradiate fluorescent X-rays of O, F, Na, Al, Si and K to the SXI prototype. This experiment reveals that our CCD has a significant low-energy tail structure in the soft X-ray response. Since the intensity of the low-energy tail is larger for lower X-ray energies, the tail is originated on the CCD surface layer. Then, we fabricate a new type of CCDs by applying an alternative treatment to its surface layer. The soft X-ray response of the CCD is measured by irradiation of monochromatic X-rays from 0.25 keV to 1.8 keV in a synchrotron facility, KEK-PF. The intensity of the low-energy tail for 0.5 keV incident X-ray is one order of magnitude smaller than that for the previous CCD. The same treatment will be applied to the surface layer of the SXI flight model.

When it comes to shoe shopping, I have always been one of those people that goes crazy in the stores. I absolutely love finding a great shoe that will work for my style, and when the price is right, I just have to invest. About three months ago or so, I realized that there were some issues with my current shoe selection, and it really paid off. I started looking for higher quality shoes, and before I knew it, I had a few pairs of great shoes that I really loved having. This blog is all about choosing higher quality shoes and being able to wear them for as long as possible.
If you're tired of giving your loved one the same types of gifts year after year, but you can't think of anything else, it's time to look up towards the sky. The answer is right in front of you every night. Stars make the perfect gift for any occasion. They shine brightly night after night and they always light the way. Here are four reasons why you should dedicate a star to your loved one.
Your Loved One's Star Will be Unique
If you want to give your loved one a truly unique gift, you need to dedicate a star to them. One of the great things about dedicating a star is that you'll know that no one else has the same gift. Each star is individually named and dedicated for the recipient, which means you won't need to worry about someone else receiving the same star. Not only that, but once your loved one's star is dedicated, it will be placed in a star registry so that everyone else will know who that star belongs to.
Your Loved One Will Learn Something
If you want a gift that brings enjoyment and knowledge, dedicate a star to your loved one. When you dedicate a star to your loved one, they'll receive a certificate to signify the registration. Your loved one will also receive information regarding their star, including size, age, and distance from earth. Your loved one will even find out what constellation their star can be found in.
Your Loved One Can Track Their Star
If you want to make sure that your loved is able to view their star, be sure to purchase a telescope as part of their gift. Along with the informational materials your loved one will receive, they'll also receive a map of where the star can be found in the night sky. With a telescope, your loved one will be able to track their star, which will allow them to develop a personal relationship with their gift.
Your Loved One's Star Will Last Forever
If you want to give your loved one a gift that will last forever, dedicate a star to them. Ordinary gifts, such as clothing, flowers, and candy will wear out, run out, or die. However, when you dedicate a star to your loved one, you'll know that you're giving them a gift that will last forever.
Don't give your loved one the same old gifts this year. Instead, give them something that will never wear out or go out of fashion. Let your loved one know you put thought into their gift by looking into star dedication services.Share

The moon has been an object of fascination and wonder for humans for thousands of years. Throughout history, the moon has been revered as a symbol of femininity, creativity, and emotional energy. From ancient civilizations to contemporary spirituality, the moon has held a special place in many cultures and beliefs. In this article, we will explore the significance of the different moon phases, the connection between moon phases, nature, and human behavior, and practical ways to live by the phases of the moon.
Understanding the Lunar Cycle
The lunar cycle is the 29.5-day period during which the moon orbits around the Earth. The cycle is divided into eight distinct phases, each with its own unique characteristics and energies. The eight phases include: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent.
The Scientific Explanation Behind the Moon’s Phases
The moon’s phases are caused by the changing angles of the moon, Earth, and the sun. As the moon orbits around the Earth, the sun illuminates different parts of the moon’s surface, creating the different phases.
Lunar Phases and Nature
The Tidal Force of the Moon
The moon has a significant impact on the Earth’s ocean tides. The gravitational pull of the moon on the Earth’s oceans causes a bulge of water to form on the side of the Earth closest to the moon, resulting in high tide. At the same time, a second bulge of water forms on the side of the Earth furthest from the moon, resulting in a second High tide. The areas in between experience Low tide.
The position of the sun also affects the tides, but to a lesser extent than the moon. When the sun, moon, and Earth are aligned, such as during a full or new moon, the gravitational forces combine to produce especially high and low tides, known as Spring tides. When the sun and moon are at right angles to each other, such as during a quarter moon, the gravitational forces partially cancel each other out, resulting in less extreme tides, known as Neap tides.
Fascinatingly, the gravitational force of the moon not only affects the Earth’s oceans but also the solid ground. The tidal force of the moon causes the Earth’s crust to rise and fall, resulting in small but measurable changes in the height of land in some areas. These changes are most noticeable in coastal regions, where they can contribute to erosion and other geological changes over long periods of time.
Animal Hunting, Mating Behaviors, and Plant Growth
Many animals, especially nocturnal ones, are known to be more active during the full moon. Some species, like the horseshoe crab, also use the moon to time their mating season.
In terms of plant growth, some people believe that planting and harvesting according to the moon phases can increase yield and improve the overall health of the crops. This practice, known as Lunar Gardening, is based on the idea that the moon’s gravitational pull affects the water content of the soil and the plants’ ability to absorb nutrients.
The moon phases play a role in the migration patterns of birds and insects. Some species are known to use the moon as a navigational tool, with the brightness and position of the moon guiding their flight paths. This is especially true for species that migrate at night, like moths and some songbirds.
Moon Phases and Their Impact on Human Nature
Many cultures and beliefs hold that the moon has a powerful influence on human behavior, emotion, and energy. Anecdotal evidence suggests that human behavior and emotion may indeed change throughout the moon’s phases.
Some people believe that they feel more energetic and creative during the Full Moon, while others report feeling more introspective and reflective during the New Moon. Some people also believe that they experience more vivid dreams and a heightened intuition during certain phases of the moon.
People who have experience working in schools, hospitals and emergency services consistently report heightened and strange behavior around the full moon.
Scientifically speaking, the impact of moon phases on human behavior is a topic that has been long debated. While there is some scientific evidence to suggest that the moon may have an effect on certain aspects of human behavior, findings are ultimately mixed and inconclusive.
Some studies have found a correlation between the full moon and an increase in certain behaviors, such as aggression, crime rates, and emergency room visits. Other studies have also found a correlation between moon phases and sleep quality and medical events, such as seizure activity.
While the scientific evidence remains inconclusive, many people believe adamantly in the influence of the moon on human behavior. In some cases, this can be attributed to the moon’s symbolic significance in various cultures and spiritual beliefs, while many of us simply find the idea of living in harmony with the cycles of nature to be intuitively appealing.
The Moon Phases and Their Energies
The new moon, or dark moon, is the first phase of the moon cycle and marks the beginning of the moon’s journey. It is associated with new beginnings, fresh starts, and the potential for growth and manifestation.
Waxing Crescent Moon
This phase follows the new moon and is characterized by a small sliver of light on the right side of the moon. It is associated with intention-setting, planting seeds, and taking action towards your goals.
First Quarter Moon
This phase occurs when exactly half of the moon is illuminated and half is in shadow. It is associated with making decisions, taking action, and overcoming obstacles.
Waxing Gibbous Moon
This phase occurs after the first quarter and is characterized by a mostly illuminated moon with a small shadow on the left side. It is associated with refining your goals, gaining clarity, and taking focused action.
This is the most well-known phase of the cycle, occurring when the moon is fully illuminated. It is associated with culmination, release, and letting go of what no longer serves you.
Waning Gibbous Moon
This phase follows the full moon and is characterized by a mostly illuminated moon with a small shadow on the right side. It is associated with gratitude, introspection, and reflecting on the lessons learned during the full moon.
Third Quarter Moon
This phase occurs when the moon is once again half illuminated and half in shadow, but on the opposite side from the first quarter. It is associated with releasing what no longer serves you, surrendering control, and preparing for a new cycle.
This final phase occurs just before the new moon and is characterized by a small sliver of light on the left half of the moon. It is associated with rest, reflection, and integration of the lessons learned during the lunar cycle.
Lunar phase rituals are practices that align with the different phases of the moon. These rituals are often based on ancient traditions and beliefs, and they can be used for various purposes such as manifestation, intention setting, and personal growth.
Lunar rituals can be a powerful way to connect with nature, the energy of the moon, and the cycles of the universe. Such lunar phase practices can lead to a greater sense of inner peace and harmony, and many people find that performing rituals during specific moon phases helps them to focus their intentions and manifest their desires more effectively.
Here are some ideas to get you started on creating your own lunar phase rituals.
The new moon is a time of new beginnings and fresh starts. A new moon ritual may include:
Setting intentions for the upcoming lunar cycle
Writing down goals and wishes for the month ahead
Starting new projects or ventures
Cleansing your living space or environment
Lighting a candle and meditating on new possibilities
The waxing crescent moon offers a time for growth and taking action towards your intentions. Rituals for the waxing crescent phase may include:
Planning out steps to achieve your goals
Starting a fitness or self-care routine
Doing a vision board or collage to visualize your intentions
Planting seeds or starting a new garden
Taking on new challenges or learning something new
This is a time of action and pushing forward towards your goals. Some rituals for the first quarter phase may include:
Checking in on your progress towards your intentions
Making adjustments to your plans or strategies
Facing and overcoming obstacles or challenges
Releasing limiting beliefs or fears
Embracing your inner warrior and taking bold steps towards your dreams
The waxing gibbous phase is all about refinement and fine-tuning your plans. Some rituals for this phase may include:
Refining your goals and plans based on feedback and experience
Asking for support or guidance from mentors or loved ones
Practicing gratitude and celebrating your progress so far
Clearing out any negative self-talk or self-doubt
Honing your skills or talents to support your goals
The full moon is a time for releasing and letting go of what no longer serves you. Some rituals may include:
Releasing any negative emotions or limiting beliefs
Letting go of physical items or clutter
Taking a cleansing bath or shower
Performing a fire ceremony to release what no longer serves you
Meditating on forgiveness and releasing any grudges or resentments
This phase is all about reflection and introspection. Some rituals for the waning gibbous phase may include:
Reflecting on your progress and accomplishments
Evaluating what worked and what didn’t in the past cycle
Journaling or writing to process emotions and experiences
Practicing self-care and nurturing yourself
Planning for the next moon cycle based on what you’ve learned
The third quarter moon phase is a time of letting go and preparing for the next cycle. Some rituals for this phase may include:
Letting go of anything that no longer serves your highest good
Evaluating your priorities and making any necessary adjustments
Releasing any attachments or expectations
Focusing on self-care and relaxation
Preparing for the upcoming new moon by setting intentions and visualizing your goals.
This phase brings rest and introspection. Some rituals for the waning crescent phase may include:
Resting and rejuvenating your body and mind
Meditating on your intentions for the next moon cycle
Connecting with your intuition and inner wisdom
Practicing self-compassion and self-love
Surrendering to the natural ebb and flow of life and the moon cycle.
In addition to moon phase rituals, there are a number of other fun and practical ways to live in harmony with the moon’s phases.
Try to align your sleep schedule with the moon phases by going to bed earlier during the waning moon and sleeping in later during the waxing moon.
Use the energy of the waxing moon to increase your physical activity and focus on building strength, and then use the energy of the waning moon to focus on stretching and flexibility.
Use the full moon as a time to tap into your creative energy and work on artistic projects, and then use the new moon as a time to reflect on your progress and set intentions for the coming cycle.
Use the new moon as a time for self-reflection and introspection, and then use the full moon as a time for celebration and self-care.
Use the waxing moon as a time to focus on building new relationships and deepening existing ones, and then use the waning moon as a time to reflect on your relationships and let go of any negative patterns or dynamics.
Lunar gardening is the practice of planting, cultivating, and harvesting crops according to the cyclical nature of the moon. This technique is based on the belief that the moon’s gravitational pull affects the moisture levels in soil and plants, and that specific activities such as planting, pruning, and harvesting are best performed during certain moon phases.
Moon mapping is a practice that involves tracking and recording your emotional, physical, and spiritual experiences throughout each of the lunar cycles. It can be a useful tool for self-reflection, personal growth, and manifesting your intentions. At each phase, you might journal about your emotions, track your physical health, or take note of any synchronicities or signs that you encounter.
Over time, you’ll start to see patterns and correlations between the lunar phases and your own experiences. This can help you to better understand yourself and your relationship to the cycles of nature. It can also help you to identify areas of your life that may need more attention or focus.
Try Living by the Moon’s Cycles!
The impact of the moon on human behavior is a complex and multifaceted topic that is likely influenced by a variety of factors, including cultural beliefs, personal experiences, and environmental factors. While the scientific evidence may be inconclusive, belief in the power of the moon is a testament to the enduring human fascination with the natural world and our place in it.
By living in alignment with the moon phases, you can create a deeper connection to the natural world and enhance different aspects of your life. Whether you choose to incorporate lunar rituals, moon mapping, or other practices, the key is to stay open to the wisdom and guidance of the moon and use that energy to support your own growth and evolution.

A Gift of Stars
An astronomer who brought the gift of the stars to everyone, Helen Sawyer Hogg led a life of remarkable achievement. She is well known for her research on variable stars in globular clusters, but she is perhaps best remembered for her astronomy column, which ran in the Toronto Star from 1951 to 1981. Helen wanted everyone to find the same joy in the stars that she did. She encouraged women to enter science, and her students remember her for her enthusiasm and warmth.
She entered Mount Holyoke College with the intention of studying chemistry, but in 1925 she changed her mind and began her study of astronomy. Her decision was fixed permanently a year later when Annie Jump Cannon visited Mount Holyoke. Indeed, on graduating in 1926, Sawyer went to the Harvard Observatory to work with Cannon and Harlow Shapley on star clusters. She obtained her doctorate in 1931 from Radcliffe College. (Harvard did not give graduate degrees in science to women at that time.)
In 1930, she married Frank Hogg, a fellow astronomy student at Harvard. Together they moved to Victoria, British Columbia, to work at the Dominion Astrophysical Observatory where Frank had a job. Helen was not hired with her husband, and she had to work as his volunteer assistant.
Hogg started her work on variable stars in globular clusters while in Victoria. She developed a technique for measuring the distance of galaxies beyond the Milky Way. She took pictures of variable stars and catalogued the cyclical changes in their brightness, which she then used to calculate their distance. Her detailed observations were published in catalogs that are still used today.
In 1935, the family moved to Ontario so that Frank could take a job at the University of Toronto. Helen became an assistant at the David Dunlop Observatory, where she would work until her death. She also taught at the University of Toronto and became a professor in 1957. In 1940-1941 she was a visiting professor and acting chair of the department of astronomy at Mount Holyoke College, and in 1955-1956 she was a program director in astronomy for the National Science Foundation. She was considered a world expert on the night sky.
In 1950 she won the Annie Jump Cannon prize of the American Astronomical Society. In 1967 she was awarded the Centennial Medal of Canada and in 1976 she was made a Companion of the Order of Canada--one of the highest honors in the nation. She became the first woman president of the physical sciences section of the Royal Society of Canada in 1960. She was also the first female president of the Royal Canadian Institute (1964-1965) and founding president of the Canadian Astronomical Society (1971-1972).
She remained active in astronomy until late in life. She published more than 200 papers during her long and distinguished career. In addition, she wrote The Stars Belong to Everyone, a popular guide to astronomy, and hosted an astronomy television series in the 1970s. Hogg received honorary degrees from six Canadian and U.S. universities. Both the Canadian National Museum of Science and Technology's observatory in Ottawa and the University of Toronto's southern observatory in Chile were named for her. When Helen Sawyer Hogg died of a heart attack in 1993, she had been a leading authority in astronomy for more than 60 years.

First Flight and Oxygen on Mars
This week is an exciting one for those interested in exploration that goes beyond our blue planet.
Firstly, NASA was able to let a helicopter – called Ingenuity – fly on Mars . An extraordinary performance, especially given that the Martian atmosphere is much thinner than the one on Earth, which makes flying the helicopter that much harder. Ingenuity’s maiden flight on Mars opens up the prospect of much easier, and quicker exploration of the Martian surface than would be possible with the brave Mars rovers, such as Curiosity and Opportunity. Yet, while it was indeed the first powered flight on another planet, it was not the first time a craft from Earth has flown on another planet, that honour goes to the Soviet Vega I and Vega II balloons which flew on Venus in 1985 [2, 3].
The second exciting event is that NASA’s Perseverance rover was the first to be able to produce oxygen on Mars . Through a device called a MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment), it is possible to convert some of Mars’ carbon-dioxide rich atmosphere into oxygen. Producing oxygen on Mars itself could drastically decrease the need to ship in oxygen from Earth, freeing scarce storage space on Mars-bound craft. It might also be one of the first foundational steps in (partially) terraforming Mars; making it suitable for Earth life.
Yet, such terraforming endeavours should always be well thought through; that is when oxygen was first introduced on Earth it was quite poisonous for almost all existing life; causing a mass extinction event, also called the Oxygen Catastrophe . Let’s hope the future of space exploration is one of careful deliberation and cooperation, instead of rash decisions and international competition.


The little book of stars
The Little Book of Stars tells the story of stellar science and what the stars mean to us from a variety of perspectives. Beginning with the "big picture;' the book moves through progressively more and more intimate views until we feel we can hold the stars in our hands, from which we can then throw them back to the sky to see our place among them. The book opens with a summary of the event that created our Universe, the Big Bang, and then goes on to describe the natures of the Big Bang's progeny, the stars-what they are, how they shine, and how they can live such immensely long lives. Approaching horne, it next examines the measures of the stars: where they are, how they are collected together from pairs to galaxies of billions, and how we learn of their individual properties. Yet closer, we look in depth at the Sun and at the physical differences among the stars, at the immense range of properties they possess. Finally, arriving at Earth, we see the signif icance of the stars to human life, how we have used them to tell our stories and to find where we are in both space and time. v From this base, the book looks more closely at stellar details, concentrating on temporal phenomena-on stellar change-and on the observational base that helps set the stage for the theory that links them all together.

Solar Eclipse safety shades
Safety shades are the most convenient method
How are eclipse glasses different from regular sunglasses? They are much, much, much more effective at blocking visible light. Researchers measure this using VLT (Visible LIght Transmittance), a standard for comparing different types of glasses.
Clear glass transmits more than 90 percent of visible light. Regular sunglasses can transmit anywhere from 15 percent to 30 percent of visible light. Mount Everest explorers, skiers and others who are outdoors in high altitudes might use extra-dark "glacier glasses," which transmit from 4 percent to 10 percent of visible light.
Eclipse glasses surpass all other glasses in eye protection; they transmit less than 1 percent of visible light. They also block 100 percent of all UVA and UVB light, which is not visible. They are the only glasses that provide adequate eye protection for viewing the Sun during eclipses and transits.
To save your vision, you must use eclipse glasses correctly. They must be in mint condition, with no holes or creases. They must shield your eyes completely when you look at the Sun. They must be used only for naked-eye viewing.
Solar Eclipse safety shades will be available for purchase at many retail outlets around Port Douglas and at the David Reneke Astronomy Lectures.
*Important Note: Read the instructions! Some of these shades are only rated for continuous viewing for viewing 30 seconds at a time!
Solar viewing glasses in a protective case will be available for sale during the David Reneke Astronomy Lectures for $4.95 each.
These cardboard "glasses" use special filter materials that effectively cut all wavelengths of light including the dangerous IR and UV that de facto materials pass to your eyes.
Other suitable filters are a number 14 arc welding filter available from welding suppliers or a special solar filters available from astronomical suppliers designed to be attached to telescopes or binoculars.
Using materials from around the home as de facto solar filters is very dangerous. These materials don't filter the dangerous UV and IR rays and can lead to blind spots even though the image looks dark enough to the eye.
Examples of unsuitable filters include pinholes, photographic film negatives, cd's/DVD's, smoked glass and silvered confectionary wrappers among many others.


Space Solar Power System (SSPS) also knows as Space-Based Solar (SBS) or Solar Powered Satellite (SPS) is the most ambitious and fanciful project in renewable engineering. It was first proposed by Physicist Dr. Peter Glaser in Science magazine in 1968. Dr. Glaser basically used theory of motion of Geosynchronous Earth Orbit (GEO) and wireless transmission of electricity. If implemented successfully, SSPS will turn milestone in the history of mankind. Our burden on fossil fuels will become zero.
“The fundamental concept is to have large solar PV cell arrays in space in geosynchronous orbit of earth. This array will collect sun’s solar energy and convert it into electrical energy by photovoltaic effect. This energy will be then converted into microwave radiation and transmitted to receiving antennas (rectenna) on earth.”

On 12 March 2015 Mitsubishi Heavy Industries demonstrated wireless electricity transmission of 10 kilowatts (kW) of power for a distance of 0.5kM. (Play video to know more)
- NASA has initiated ‘Space Solar Power Exploratory Research and Technology‘ program(SERT) in 1999 for research and feasibility studies of SSPS.
- On earth we receive only 1 kW/m2 solar power where as in space whole solar power (1365W/m2) can be utilized for solar-electric conversion.
- Electricity from Space Solar Power System will be available all the time because it does not come under earth’s shadow (as it is in space). However, it cannot generate power during eclipses which occur for few minutes in a year.
- Once installed, Space Solar Power System will become the most stable source of energy
- With SSPS, we can transmit energy anywhere on planet earth (provided we installed receiving stations in various regions) without having electrical grid network.
- There are no environmental impacts such as green house or waste which are major drawbacks conventional power plants (thermal, nuclear, etc)
- Space Solar Power System may be damaged by space debris which is available in abundant volume in space.
- Cost of launching satellite to place this system in Geosynchronous Earth Orbit is enormous.
- It is difficult to manufacture extremely large as well as light weight PV array structures due to technological limitations.
- The transmitted microwave beams need to be checked against adverse effect on traditional communication system, electronic appliances, airplane, human health and many things…

study of the orbital motion of satellites moving around the earth. by Yvonne Block Download PDF EPUB FB2
The two body orbital motion is considered as an undisturbed movement of a body about a planet. In Space, there is an unexpected environment that can cause disturbances to the motion of a satellite.
The objective of this chapter is to present the perturbations due to the Earth and Sun that highly affect the orbital motion. Orbital motion occurs whenever an object is moving forward and at the same time is pulled by gravity toward another object.
The forward velocity of the object combines with acceleration due to gravity toward the other object. The result is a circular or oval path called an orbit, in which one object keeps moving around the other.
Sputnik, the first artificial Earth satellite, was launched by what was then called the Soviet Union on October 4, Since that time, thousands of satellites have been placed into orbit around Earth, and spacecraft have also orbited the Moon, Venus, Mars, Jupiter, Saturn, and.
David R. Brooks Langley Research Center Hampton, Virginia. National Aeronautics and Space Administration Scientific and Technical Informalion Office PREFACE This report provides, by analysis and example, an appreciation of the long- term behavior of orbiting satellites at a level of complexity suitable for the initial phases of planning Earth monitoring missions.
Earth’s orbital distance from the Sun varies a mere 2%. The exception is the eccentric orbit of Mercury, whose orbital distance varies nearly 40%. Determining the orbital speed and orbital period of a satellite is much easier for circular orbits, so we make that assumption in the derivation that follows.
As we described in the previous. Many ancient and medieval cultures believed the stars and the planets rotated around a fixed Earth. The complex motions of the planets—which sometimes move backwards across the sky (retrograde motion, shown in the photo)—led Renaissance astronomers to question this geocentric astronomers discovered the laws of orbital mechanics, transforming natural philosophy into the Author: Holli Riebeek.
Motion because the Principia is in Latin, and there is more than one English translation. Newton’s Laws of Motion Newton’s First Law - A body at rest stays at rest, and a body in motion stays in uniform, straight-line motion, unless acted upon by a net force.
Newton’s Second Law - The time rate of change of momentum is propor. Hannah has information about an object in circular orbit around Earth. mEarth = × kg G = × What additional information does Hannah need in order to calculate the tangential speed of the orbiting object.

Many others orbit in s miles (35, km) from the planet in the geosynchronous belt, seen as the red-dotted arc chronous satellites go around the planet once every 24 hours, the same time it take Earth to rotate once —. Kepler has two different sets of laws of orbital motion.
One set applies to planets orbiting the sun, and the other set applies to man-made satellites orbiting the Earth Which orbital parameter must use a reference point in space, because an earth based point will move as the earth rotates. Why is there a ring of satellites around the. question_answer22) A satellite is moving around the earth with speed v in a circular orbit of radius r.
If the orbit radius is decreased by 1%, its speed will [MP PET99, ] A) Increase by 1% done clear. B) Increase by % done clear. First Law of Motion. Newton’s First Law of Motion states that a body in motion keeps the same motion unless acted upon by an outside force.
Likewise, if it is not moving, it remains that way unless a force acts on it. Any moving object in space will travel in a straight. If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit.
If this is the case, the satellite will move off into. Orbital Motion. We commonly talk about satellites orbiting Earth. But what does that really mean. When a satellite, space shuttle, or some other object is orbiting a planet, it maintains a circular orbit around the planet a constant distance off the surface.
Manmade satellites typically orbit. A satellite is an object that moves around a larger object. Thousands of Satellites launched into orbit around Earth. First, look into the Preliminaries about 'Satellite Orbit', before moving to Satellite Ephemeris data and conversion utilities of the OM-MSS software.
A) It is the true, not apparent, motion of a star in space. B) It is the apparent shift as we go to opposite sides of our orbit every six months. C) It is the annual apparent motion of a star across the sky.
D) It is the motion of a star towards or away from us, revealed by Doppler shifts. E) It is the orbital motion of a star around the Galaxy. At just the right speed, it will move around the Earth in a circular motion. This type of motion and the path that a satellite moves in is called an orbit.
Close to the Earth at an altitude of km, a satellite needs to be moving at 8 kilometres per second (28 km/h) to stay in orbit. Start studying Satellite Motion. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Describe the shape of the orbit of a satellite moving around the Earth.
traces an oval-shaped path called an ellipse states that the square of the orbital period a planet is directly proportional to the cube of the. We know that the path of satellite revolving around the earth is known as orbit.
This path can be represented with mathematical notations. Orbital mechanics is the study of the motion of the satellites that are present in orbits. So, we can easily understand the space operations with the knowledge of orbital motion.
Orbital Elements. A kg satellite is in a circular orbit about Earth at a height above Earth equal to Earth's mean radius. (a) Find the satellite's orbital speed(m/s). (b) Find the period of its revolution(h). The speed can’t vary as long as the satellite has a constant orbital radius — that is, as long as it’s going around in circles.
This equation holds for any orbiting object where the attraction is the force of gravity, whether it’s a human-made satellite orbiting the Earth or the Earth orbiting the sun. In this episode, students will learn how to combine concepts learned in the study of circular motion with Newton’s Law of Universal Gravitation to understand the (circular) motion of satellites.
While real orbits are very rarely circular, they should still find it satisfying to see the relative simplicity with which the laws they have learned lead to an explanation of Kepler’s 3 rd law.
Now, we launch eastward. We pick the time of launch (in Deep Space 1's case, early morning) to give the rocket time to accelerate as it goes partway around Earth. Then, when the spacecraft is headed in the same direction as Earth's orbital motion around the sun, the rocket gives it a final boost out of Earth orbit and on its way.

In this study, the moving trajectories of the nanopiezo stage in. Unlike satellites in GEO that must always orbit along Earth’s equator, LEO satellites do not always have to follow a particular path around Earth in the same way – their plane can be tilted.
This means there are more available routes for satellites in LEO, which is one. In general, few things are moving at speeds fast enough for us to notice relativity. For large, slow-moving satellites, Newton’s laws still define orbits. We can still use them to launch Earth-observing satellites and predict their motion.
We can use them to reach the Moon, Mars, and other places beyond Earth. The first law states that planets move around the sun on elliptical orbits.
The second law states that a planet sweeps out equal areas in equal times. According to the third law, the square of the orbital period is proportional to the cube of the distance to the sun. These are purely empirical laws, however.
Artificial satellites have circular orbits and exhibit simple harmonic motion. The orbital period refers to the time required for the satellite to completely revolve around the larger object. A satellite is a device which revolves around earth with a constant angular velocity and time period.
The acceleration required to do circular motion comes from the force of attraction that earth. With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.
This is approximat mph (27, kph) at an altitude of miles (Orbital Motion of a Satellite in a Circular Orbit. A satellite of mass m needs centripetal force to move in a circular orbit of radius r with an orbital speed v around a planet of mass M.

Found! First Earth-Size Planet That Could Potentially Support Life
Astronomers have discovered a planet about the size of Earth,
orbiting its star in the zone where oceans of liquid water would be possible.
A study of the newly-found planet indicates it could have an Earth-like atmosphere and water at its surface. The planet Kepler-186f is the fifth planet of the star Kepler-186, 490 light-years away.
The planet has 1.11 times the Earth’s mass. Its radius is 1.1 times that of Earth. Kepler-186f orbits at 32.5 million miles (52.4 million kilometers) from its parent star. Its year is 130 Earth days.
The planet orbits Kepler-186, an M-type dwarf star less than half as massive as the sun. Because the star is cooler than the sun, the planet receives solar energy less intense than that received by Mars in our solar system, despite the fact that Kepler-186f orbits much closer to its star.
