Riding his own rocket, Amazon and Blue Origin founder Jeff Bezos streaked into space Tuesday on a thrilling 10-minute up-and-down flight, a high-tech joyride that sets the stage for the start of commercial passenger service later this year.
“Best day ever!” an elated Bezos said upon landing.
Competing head to head with fellow billionaire Richard Branson, who flew into space aboard his Virgin Galactic rocketplane July 11, Bezos blasted off with his brother Mark and two history-making passengers: 82-year-old aviation pioneer Wally Funk, the oldest person to fly in space, and Oliver Daemen, an 18-year-old Dutch student who is the youngest ever to fly in space.
Funk, who was barred from NASA’s initially all-male astronaut corps in the 1960s, finally got her chance to prove the naysayers wrong, realizing a lifelong dream.
The crew lifted off from the company’s West Texas launch site at 9:12 a.m. EDT.
Climbing straight up atop 110,000 pounds of push, the rocket rapidly accelerated as it consumed its load of supercold liquid oxygen and hydrogen propellants, pushing the passengers back in their recliner-style seats with about three times the normal force of gravity.
In a little more than two minutes, the spacecraft was shooting skyward at three times the speed of sound, dwindling to a blur more than 30 miles up. A few seconds later, at an altitude of about 45 miles, the booster’s company-designed BE-3 main engine shut down and the crew capsule was released to fly on its own.
Coasting upward along an unpowered ballistic trajectory, Bezos and his crewmates enjoyed about three minutes of weightlessness, unstrapping, floating about the cabin and taking in the view through the largest windows ever built into a spacecraft.
“I love it!” Funk exclaimed.
Tossing candy and ping pong balls back and forth, doing somersaults and marveling at the view, the crew cavorted like school kids, clearly thrilled by the experience.
“Who wants a Skittle?” Bezos called. “All right, see if you can catch this in your mouth.” Daemen did just that, prompting cheers in the cabin. “Toss me one,” Bezos said. “Awesome!”
“That is just incredible,” Daemen said a moment later.
“I love it, I love it,” Funk said again. She could be seen floating in front of a window, staring out at Earth and space, a view she had dreamed about for decades.
The capsule, named “First Step,” reached a maximum altitude of 66.5 miles, more than four miles above the internationally recognized 62-mile-high “boundary” between the aerodynamically discernible atmosphere and space.
That’s the altitude recognized by the Fédération Aéronautique Internationale, a Switzerland-based organization that sanctions aerospace records.
Branson’s Virgin Galactic spaceplane flies about 10 miles lower but well above the 50-mile altitude recognized by NASA and the Federal Aviation Administration as the point where wings, rudders and other aerosurfaces no longer have any effect.
Two minutes after booster engine shutdown and the onset of weightlessness, the crew was warned they had about a minute to make their way back to their seats to strap in for re-entry. All too soon, weight returned as both began falling back into the lower atmosphere.
The crew had no problems strapping back in. And even on the way down, the view was spectacular. “It’s dark up here!” Funk exclaimed. One of her crewmates could be heard saying “well, that was intense” while another said he was “happy, happy, happy!”
The reusable New Shepard booster, meanwhile, headed back to Earth on its own, plunging tail first toward a landing pad two miles from the launch site.
The rocket relied on deployable air brakes and steering fins to maintain its orientation before re-igniting its BE-3 engine, unfolding four hinged legs and settling to a picture-perfect landing.
“Your booster has landed,” Blue Origin capsule communicator, or CAPCOM, Sarah Knights radioed the crew.
“It’s great to hear about the booster,” Bezos replied replied. “You have a very happy crew up here, I want you to know.”
At an altitude of about 2,700 feet, three large parachutes unfurled and inflated, slowing the New Shepard’s descent to about 16 mph.
Then, just six feet or so off the ground, nitrogen powered thrusters fired, slowing the capsule to just 1 mph and kicking up a roiling cloud of dust as the spacecraft gently touched down.
“Welcome back to Earth, First Step, congratulations to all of you,” Knights radioed.
“Very happy group of people in this capsule,” Bezos replied. “We’re so grateful to everybody who made this possible. Thank you.”
Blue Origin recovery crews converged on the capsule within minutes of touchdown to open the hatch and help the returning astronauts exit. All four emerged in obvious high spirits, smiling and hugging family members and support personnel.
“Oh my God!” Bezos told reporters later. “My expectations were high, and they were drastically exceeded. The zero G (gravity) piece may have been one of the biggest surprises because it felt so normal, it felt almost like humans evolved to be in that environment. … It’s a very pleasurable experience.”
The most profound aspect, he said, was the view of Earth from an altitude that showcased the fragility of the planet and its thin atmosphere.
“Every astronaut, everybody who’s been up into space, they say this, that it changes them, and they look at it and they’re kind of amazed and awestruck by the Earth and it beauty, but also by its fragility,” he said. “And I can vouch for that.
“It’s one thing to recognize that intellectually, it’s another thing to actually see with your own eyes how fragile it really is. And that was amazing.”
Funk, who once underwent grueling medical tests only to be barred from NASA’s early astronaut corps, said she enjoyed “every minute of it.”
“I want to thank you, sweetheart, because you made it possible for me,” she told Bezos. “I’ve been waiting a long time to finally get it up there. … I loved it. I loved being here with all of you, your families. We had a great time. It was wonderful. I want to go again, fast!”
“I have been waiting a long time to finally get up there”
Former astronaut Jeff Ashby, now chief of mission assurance at Blue Origin, pinned astronaut wings on all four crew members.
As for Tuesday’s flight, it was the 16th successful launch of a New Shepard spacecraft, the third for the booster and First Step capsule, and Blue Origin’s first with passengers on board.
Blue Origin plans to launch three more New Shepard flights before the end of the year, one with science payloads on board and two with passengers.
“We’re going to fly human missions twice more this year,” Bezos said. “What we do in the following year, I’m not sure yet. We’ll figure that out and what the cadence will eventually be. We want the cadence to be very high.”
He added, “We’re approaching $100 million in private sales already and the demand is very, very high. So we’re going to keep after that.”
Ticket prices have not been revealed. The cost of a flight aboard Virgin Galactic’s spaceplane is believed to be around $250,000 and Blue Origin tickets are expected to be competitive. But both companies hope economies of scale will eventually lower prices to less astronomical levels.
“We’re not done once we fly this vehicle, it’s really just the beginning,” Lai said. “We are going to ramp up operations. We’re going to have dozens and eventually hundreds and thousands of astronauts we hope fly on New Shepard. So it is just the beginning. But it is a monumental moment nevertheless.”


NASA launches newest satellite
NASA’s super-high-flying fleet of communication satellites just got bigger.
An unmanned rocket blasted into a chilly, clear sky on Thursday night carrying the latest, third-generation Tracking and Data Relay Satellite.
NASA uses the TDRS satellites to support the International Space Station and Hubble Space Telescope, among other craft.
The network is 35,800km high, at various locations above the equator, and allows continuous two-way contact with the space station and its six inhabitants.
The TDRS system is so vital it’s considered a national asset.
A modern-day human space program would be difficult if not impossible without the constant coverage provided by the TDRS satellites, said Badri Younes, NASA’s deputy associate administrator for space communications and navigation.
Ground stations – limited in number – would provide just a fraction of that capability.
Each satellite has a pair of dish antennas 4.5 metres in diameter.
“Not only are we getting global coverage 100 per cent of the time, we are getting it in real time,” Younes said, snapping his fingers, at a news conference earlier this week.
“Without such support, we’d have to live with coverage around the 10 to 15 per cent,” he said.
“No human spaceflight program can be supported at this data rate. And even our ability to respond real time to emergency would diminish drastically. So that’s why the TDRS has been declared as a national asset.”
NASA is the primary user; the TDRS system also occasionally assists other countries’ space agencies and the US military. In 2002, a TDRS satellite allowed Massachusetts doctors to oversee knee surgery performed at the South Pole.
This newest $US350 million ($A400 million) satellite – which will work its way up from a temporarily low orbit – is designated “L” in the TDRS series. NASA will rename it TDRS-12 once it’s checked out in orbit, by late spring.
NASA launched its first TDRS in 1983 aboard a space shuttle. The previous satellite, TDRS-11, soared in January 2013.
Officials said they need six active TDRS satellites in orbit at any one time, along with a ready-to-go spare.
The newly launched, Boeing-built satellite will serve as an extra spare. The next in the series – TDRS-M – will be launched sometime in the early 2020s.

The middle region is colored green; doubly ionized oxygen emits greenish-blue light. , In the extreme east is RR Lyrae, the prototype of the large class of variables known as RR Lyrae variables, which are pulsating variables similar to Cepheids, but are evolved population II stars of spectral types A and F. Such stars are usually not found in a galaxy's thin disk, but rather in the galactic halo. Calliope was the eldest of the Muses, the ancient Greek goddesses of music, song and dance.

Pitch was changed on individual strings by pressing the string firmly against the fingerboard with the fingertips.  The star was the first single main-sequence star other than the Sun to be known to emit X-rays, and is surrounded by a circumstellar debris disk, similar to the Kuiper Belt. Greek mythology and the Constellation Lyra. Mythology of the Lyra Constellation Lyra represents a harp-like stringed instrument that was gifted to Orpheus by Apollo, the Greek God of Light.

A handy table of equivalents between 15 similar Greek and Roman gods—Venus is Aphrodite in Roman clothing, while Mars is the Roman version of Ares—shows just how similar they were. Medium brown hair was unusual.

Others view the lyre and zither as being two separate classes. There's no real legend behind this one but it maybe one of the Stymphalian birds that Hercules had to kill as part of his twelve labours. Such stars serve as standard candles, and thus are a reliable way to calculate distances to the globular clusters in which they reside. As the four strings led to seven and eight by doubling the tetrachord, or series of four tones filling in the interval of a perfect fourth, so the trichord is connected with the hexachord or six-stringed lyre depicted on many archaic Greek vases. Made by Hermes from a tortoise shell, given to Apollo as a bargain, it was said to be the first lyre ever produced. Lyra represents the lyre played by Orpheus, musician of the Argonauts and son of Apollo and the muse Calliope. The central star, V477 Lyrae, is an eclipsing post-common-envelope binary, consisting of a white dwarf primary and an oversized secondary component due to recent accretion.  It was discovered in 1779 by Antoine Darquier, 15 years after Charles Messier discovered the Dumbbell Nebula.  The Kepler-20 system contains five known planets; three of them are only slightly smaller than Neptune, while the other two are some of the first Earth-sized exoplanets to be discovered. The most interesting things about the constellation is Vega and the Lyrids meteor shower. Some of the cultures using and developing the lyre were the Aeolian and Ionian Greek colonies on the coasts of Asia (ancient Asia Minor, modern day Turkey) bordering the Lydian empire.

The plane of the orbit is aligned with Earth and the system thus shows eclipses, dropping nearly a full magnitude from its 3rd-magnitude baseline every 13 days, although its period is increasing by around 19 seconds per year.  Both systems, however, have very similar radial velocities, and are the two brightest members of a sparse open cluster known as the Delta Lyrae cluster.

Unfortunately, near the very end, Orpheus faltered and looked back, causing Eurydice to be left in the Underworld forever. In Greek mythology, Lyra represents the lyre of Orpheus. Lyra is a northern summer constellation, which is highest in the midnight sky in the months around June. Apollo's Lyre - A Myth with a Moral This story presents the myth of the Lyra constellation.  Also just visible to the naked eye is the peculiar classical Cepheid V473 Lyrae. The constellation name means The Lyra. In order not to be followed, he made shoes for the cows which forced them to walk backwards. From the entrails and a tortoise/turtle shell, he created the Lyre. JO: German/French composer, 20 June 1819 - 5 October 1880. This is the principle on which the modern violin and guitar work. Orpheus was a gifted musician whose music charmed both the living and inanimate. While fleeing from an attack by Aristaeus, she stepped on a snake that bit her, killing her.  In Wales, Lyra is known as King Arthur 's Harp (Talyn Arthur), and King David's harp. , Lyra is bordered by Vulpecula to the south, Hercules to the east, Draco to the north, and Cygnus to the west. The number of strings on the classical lyre varied at different epochs and possibly in different localities—four, seven, and ten having been favorite numbers. That holy mouth of the Muses PINDAR, that sweetly prattling Siren BACCHYLIDES, those Aeolian Graces of SAPPHO; the book ANACREON wrote, STESICHORUS whose work was fed from the stream of Homer; the delicious scroll of SIMONIDES, IBYCUS gatherer of the bloom of Persuasion and of lads, the sword ALCAEUS used, to shed tyrant …  Originally classified as a VY Sculptoris star due to spending most time at maximum brightness, since around 1979 the system has been dominantly at minimum brightness, with periodic outbursts. Lesley Brown: The New Shorter Oxford English Dictionary. The form of this lyre is a very ancient symbol for the musical arts. The system was one of the first main-sequence eclipsing binaries containing G-type star to have its properties known as well as the better-studied early-type eclipsing binaries. , M57, also known as the "Ring Nebula" and NGC 6720, at a distance of 2,000 light-years from Earth is one of the best known planetary nebulae and the second to be discovered; its integrated magnitude is 8.8. There is no clear evidence that non-Greco-Roman lyres were played exclusively with plectra, and numerous instruments regarded by some as modern lyres are played with bows. Those who differ with that opinion counter by calling the lute, violin, guitar, banjo, and other such instruments "independent fingerboard lyres," as opposed to simply "fingerboard lyres" such as the Welsh crwth, which have both fingerboards and frameworks above their resonators. Mythology In Greek mythology, Lyra was associated with the myth of Orpheus, the musician who was killed by the Bacchantes. When he died, his lyre was thrown into a river. The last of the bowed yoke lyres with fingerboard was the "modern" (c. 1485–1800) Welsh crwth.  Vega forms one corner of the famous Summer Triangle asterism; along with Altair and Deneb, these three stars form a prominent triangle during the northern hemisphere summer.  Before Greek civilization had assumed its historic form, there was likely to have been great freedom and independence of different localities in the matter of lyre stringing, which is corroborated by the antique use of the chromatic (half-tone) and enharmonic (quarter-tone) tunings pointing to an early exuberance, and perhaps also to a bias towards refinements of intonation. These Lyrans were also Caucasian, of light skin, hair and eyes. Joining Jason and the Argonauts, his music was able to quell the voices of the dangerous Sirens, who sang tempting songs to the Argonauts. Legend has it that Zeus placed Orpheus’ lyre in the sky after he died. , German cartographer Johann Bayer used the Greek letters alpha through nu to label the most prominent stars in the constellation. The sarcophagus was used during the Mycenaean occupation of Crete (c. 1400 BC). In Greek mythology, Lyra represents the lyre of Orpheus.  It is the prototype of the Beta Lyrae variables, eclipsing semidetached binaries of early spectral types in which there are no exact onsets of eclipses, but rather continuous changes in brightness. MYTH.  Material evidence suggests lyres became more widespread during the early Middle Ages, and one view[whose?] The cultural peak of ancient Egypt, and thus the possible age of the earliest instruments of this type, predates the 5th century classic Greece. In April 2013, it was announced that of the five planets orbiting Kepler-62, at least two—Kepler-62e and Kepler-62f—are within the boundaries of the habitable zone of that star, where scientists think liquid water could exist, and are both candidates for being a solid, rocky, earth-like planet. Lynceus was one of the Argonauts and he participated in the hunt for the Caledonian Boar. From the equator to about the 40th parallel south it is visible low in the northern sky during the same (thus winter) months. Lyra also contains the Ring Nebula, a planetary nebula that appears as a sphere of glowing gas. In the Classical era, when the Muses were assigned specific artistic spheres, Calliope was named Muse of epic poetry. , A remarkable long-duration gamma-ray burst was GRB 050525A, which flared in 2005.

Online dating dangers facts about earth
And of course, NASA has known about the mystery planet for years, but declined to warn us … Finally, after the announcement of “Planet Nine” in January, conspiracy theorists have proved to the skeptics that they have been right this entire time, and NASA finally has to admit its wrongs.
The planet, according to Caltech researchers, has a mass about 10 times that of Earth and takes about 15,000 years to make a full orbit around the sun – And it’s heading towards Earth, with a collision date of August 21, 2016.
We have concrete evidence that proves Nibiru is headed straight for earth with a collision that will destroy life as we know it.
NASA is just trying to avoid mass panic and chaos within our world.
If you are a victim of dating fraud report it to Action Fraud.
If you are a victim of blackmail or extortion, keep the evidence - take screenshots and save messages, the police may require it.
Doomsayers have prophesied for decades about a giant, rogue planet in our solar system — dubbed Planet X or Nibiru — that has the capacity of colliding or passing near Earth, with catastrophic consequences.
The anonymity of the internet allows people to hide facets of their personality, from a relatively harmless lie about weight, to lies about financial problems and even creating a fake persona – this is called catfishing.
If you aren’t careful, you may be out of pocket and broken-hearted.

As if space and astronauts weren’t cool enough already, Commander Chris Hadfield has gone and made them infinitely cooler.
Since December 2012, Commander Hadfield has broadened our knowledge of life in space far beyond what we’ve learned from watching Apollo 13 and eating astronaut “ice cream.” The tech savvy Canadian astronaut has spent the last five months not only doing – er – space things at the International Space Station, but on his (gravity) free time has become a bona fide star of social media.
On twitter he’s exchanged tweets with William Shatner, George Takei and other Star Trek actors (among others). He has a popular Tumblr blog filled with amazing photos he’s taken from space (presumably to make us all feel silly about our Tumblr blogs with not-so-amazing cat gifs). On Reddit, he hosted one of the top AMA (ask me anything) threads of all time. But perhaps the place he’s gained the most notoriety is YouTube.
Via the Canadian Space Agency channel, he’s posted dozens of videos to answer pressing questions from those of us grounded on Earth; things like how eyesight is affected in space, how they sleep, and how they brush their teeth. And just a few days ago, he responded to a request to record a version of David Bowie’s “Space Oddity”.
Perhaps the most poignant version of the song to date, it’s garnered over 7 million views online and the seal of approval from Mr. Bowie himself. The lyrics and melody of the song are already moving, but paired with views of the Commander moving solo throughout his ship with Earth as his backdrop, it becomes a significant and stunning tribute.
One of his most quotable quotes he said during his Reddit AMA was, “Every decision you make…turns you into who you are.” I guess that means he simply decided to be awesome.

"What's Up in the Observatory" in Eilat is a special attraction that is both educational and entertaining. Eitan Schwartz leads the participants, who follow behind his car, to a dark site near Be'er Ora, about a 15 minute drive north of Eilat. The program begins the minute you arrive and turn off your car's lights. You immediately see the incredible star-filled sky. Older participants may remember the skies of their youth, but there are few places today where you can see as many stars as you see while Eitan is setting up. As you are waiting, you can lie on the blankets provided to begin enjoying the quiet and spectacular sky.
Eitan uses two main tools to show the sky. One is an incredible green laser that makes people gasp the first time he turns it on. With the green laser, everyone can see and understand which stars are being talked about. The second is his large telescope which needs a few minutes to set up. With the help of the telescope's computer, Eitan is able to quickly move from one heavenly body to the next.
Before the telescope is ready, Eitan begins pointing out the stars, and we see groups of stars whose names are familiar, like Orion's Belt, and less familiar groups like the Northern Arrow, different colored stars, and clusters of stars and fuzzy patches that we never knew were there –all this with the unaided eye.
As we line up to look through the telescope, Eitan explains how best to see through the eyepiece and continues explaining about the phenomena we are seeing through it. The fuzzy area that we saw without the 'scope turns out to be M 42, a diffuse Nebula; a cloud of glowing gases surrounding stars that are still being formed. He continues after everyone has taken a turn looking. Some of the kids even looked a few times. He has patience for everyone and everyone is listening to his every word or introducing new questions of wonder.
As he moves on to a different part of the sky to show us an open cluster of stars that looks like a field of diamonds, he stops using the telescope for a while and points out the constellations in with the laser, telling the stories that bring them together and bring the abstract figures to life. We continue learning and seeing unimaginable beauty until Eitan finally says, “Let's look at Jupiter, our close neighbor, only 800 million kilometers from us,” thus finishing the hour and a half session with an amazing finale.

If I remember my high school science classes correctly, stars like our sun spend a good long time burning brightly at the center of their solar systems, providing the light and heat and gravity that keep everything moving and, in our case, alive. But as many a poet reminds us, all good things must come to an end. Eventually, once their hydrogen is gone and after brief explosions, most stars settle into new existences that consist of gradual cooling and general diminishing of their once radiant dominance.
I’ve been thinking about the life cycle of a star a lot in regards to this school year, as there are a few similarities. Generally speaking, the role of teacher has long been to be the undisputed sun at the center of her/his/their classroom. The classwork, class structure, and class community have all traditionally orbited around the teacher, with the students acting as satellites of sorts, satellites whose trajectory is almost wholly dependent on the sun they orbit.
But last spring after our educational systems largely exploded, many teachers faced a reality that was not unlike the reality that a star faces after it has blown up. Anyone who has spent more than five minutes on a Zoom call likely knows that even the most dynamic presenters just don’t shine as brightly on Zoom as they do in person, and the gravitational pull of a class from a distance just isn’t the same as when thirty five bodies are all crammed together in a 500 sq. ft. room.Continue reading “What the Life Cycle of a Star Can Teach Us About This School Year”

The sky is the limit for reopened COSI Planetarium
“It’s a dream come true.”
That’s the sentiment held by Kate Storm, the Director of Theaters at Columbus, Ohio’s Center of Science and Industry (COSI), when speaking of the reopening of the COSI Planetarium. “I worked at the planetarium when it closed in 2004 and it was heartbreaking,” she says, “for me, it became a mission to get it open again.”
A beloved institution nestled along the west bank of the Scioto River, COSI welcomes hundreds of thousands of visitors annually to explore various science-focused exhibits, activities and events. One of the more popular attractions is the COSI Planetarium, a fulldome, 211-seat theater with a 60 ft.- diameter concave screen. First opened in 1999, it closed 5 years later and then sat unused until this latest technology upgrade and reopening in the fall of 2014.


In the past, the National Philharmonic has teamed up with NASA to create multimedia presentations of existing classical pieces, such as Gustav Holst’s “The Planets,” and such pairings of classical music and celestial imagery have become commonplace at any given planetarium. (The National Symphony Orchestra, for instance, will present its own program of “The Planets” coupled with NASA imagery on July 7 at Wolf Trap.)
With “Cosmic Cycles,” Dehlinger and a team of multimedia producers at NASA’s Goddard Space Flight Center flipped this process. The music was produced over the past year in an exchange of original music and images processed from the Hubble and James Webb space telescopes, as well as hundreds of richly rendered 3D visualizations, animations and simulations.
A grand seven-movement narrative arc emerges from the sequence of images and music, as the presentation shuttles listeners from the furnace of the sun to the cradle of the Earth, across the expanse of our still-mysterious solar system and onward into the squiggly lines and black holes of the unknown.
In a phone chat a week or so before Thursday’s premiere, Dehlinger said he could apprehend the vastness of space only by submitting a more meditative approach to the material (or lack thereof). But the results weren’t nearly as atmospheric as that might suggest.
Throughout the work, Dehlinger effectively builds atop the foundation of a searching four-note motif that echoes other monolithic melodies we’ve come to connect with the cosmos, including the clarion dawn of Strauss’s “Also sprach Zarathustra” or John Williams’s five-note hello from the film “Close Encounters of the Third Kind.”
But this theme becomes the basis for a harmonically rewarding wander through the stars that finds the substantial 81-piece orchestra — commandingly conducted by Piotr Gajewski — achieving unexpected lightness. (On a somewhat related note, Capital One Hall may have been a bit too appropriate a venue to virtually plunge us into the vacuum of space: Its acoustics are clear and close, but suffocatingly still. I expect there to be a bit more air in the air when the program repeats Saturday at Strathmore.)
Twinkling chimes and ascendant strings open the first movement, “The Sun,” which flies low over the churning surface of the closest star. A pipe organ traces the transit of the tiny black dot of Mercury across its boiling backdrop. Solar winds and bubbles of coronal plasma emerge as bursts of brass, with little flares of light registering as sweeps of harp.
The second and third earthbound movements dig more deeply into turfy textures: arpeggiating cellos assisting a data visualization in describing dust storms and volcanic eruptions; a whoosh of strings painting the sinister rainbow cloud of sulfur dioxide emissions; licking flutes enacting the flames of global wildfires seen from space. Elsewhere, the hiss of a rain stick underlines footage of atmospheric rivers, and a plodding glockenspiel trails animal migration patterns. An undulating meadow of strings runs below a map of global agriculture, a capture of the planet’s fertility and fragility.
Dehlinger’s music does wonders to freshen a sequence of sights we’ve never seen yet have seen a million times: photos from space of cities ablaze in electric light, mountain ranges rumpled like blankets, the branching veins of vast river systems.
In turn, the images seem to have drawn out an ambitious sonic palette. Much like space itself, stretches of “Cosmic Cycles” suffer from an impersonal uniformity. Dehlinger comfortably channels the tenderized awe of a well-produced nature documentary — a universal beauty that sometimes felt set to autopilot.
But he thrives when the cosmos gives him material to work with — like the pocked lunar surface of Schrödinger Basin, or the colossal wad of space granola targeted by the DART mission (Double Asteroid Redirection Test), or the colliding winds of a binary star.
At least some of this is pure instinct: Dehlinger told me he had followed an impulse when scoring the final movement of “Cosmic Cycles” in B flat. Later, when incorporating a NASA sonification of a particularly talkative black hole in the Perseus galaxy cluster, he realized that its horrifying howl was also in B flat — albeit 57 octaves below middle C.
It’s not easy to wick drama from data or sentiment from space, but Dehlinger’s orchestrations for potentially stale stills and inscrutable-but-pretty mathematics packed an unexpected emotional punch. Gajewski, along with his orchestra, was in fine form, handling the work’s many swerves and dives with ease and confidence. Kudos in particular to concertmaster Laura Colgate, whose several solos left gleaming trails in the air.
The evening closed with a short encore in the form of “Fanfare to Artemis,” penned by Dehlinger at the start of 2022, after the news of the Artemis mission to the moon but before he’d written a note of “Cosmic Cycles.” It was perhaps the most traditionally triumphant-sounding skyward salute of the evening — the Space Force could learn a thing or two. But with its big blasts of brass, it was also a reminder of what we want from the heavens in the first place: a sign that someone’s listening.
Cosmic Cycles repeats Saturday at Strathmore Music Center. nationalphilharmonic.org.


Difficulties and arrangements in profound space travel
Profound space travel has for some time been a fantasy of humankind, with dreams of investigating far off planets, moons and, surprisingly, past our planetary group. While critical headway has been made in space investigation throughout the course of recent many years, profound space travel presents a special arrangement of difficulties that should be defeated to turn into a reality. In this article, we investigate a portion of the key difficulties related with profound space travel and the imaginative arrangements that researchers and specialists are creating to address them.
1. Immense distances and travel times
One of the most troublesome difficulties of profound space travel is the tremendous distances included. The closest star framework, Alpha Centauri, is north of four light-years from Earth, meaning it would require over four years to go there at the speed of light. Indeed, even inside our own planetary group, excursions to far off planets like Neptune or Pluto can require quite a while.
Arrangement: High level Drive Systems
To manage the issue of colossal distances and long excursions, researchers are chipping away at creating progressed impetus frameworks. One promising idea is the utilization of atomic warm impetus, which would essentially lessen travel times by speeding up shuttle. Likewise, sun oriented sails and laser impetus frameworks are being investigated to empower quicker and more proficient interplanetary travel.
2. Radiation exposure
Profound space is loaded up with inestimable beams, including high-energy particles from the Sun and then some. Delayed openness to this radiation can be hurtful to space travelers and damage shuttle frameworks.
Arrangement: Radiation Shielding
The advancement of successful radiation safeguarding is basic to safeguarding space travelers during profound space missions. Inventive materials and plans are being investigated to make successful safeguards that can obstruct or moderate the hurtful impacts of grandiose beams. For instance, water is a decent radiation safeguard, and space apparatus might contain water-based protecting frameworks.
3. Life support and sustainability
Profound space missions can keep going quite a while and guaranteeing the manageability of life emotionally supportive networks is a huge test. Furnishing space explorers with adequate food, water and oxygen for long-span missions is fundamental.
Arrangement: Shut Circle Life Backing Systems
Shut life emotionally supportive networks are being created to address the maintainability issue. These frameworks reuse and refine air and water, as well as produce food utilizing aquaculture or other imaginative cultivating strategies. This diminishes the need to convey a lot of provisions from Earth, making profound space missions simpler.
4. Mental and social isolation
The confinement of profound space travel can mentally affect space travelers. Being caught in a spaceship for broadened timeframes without the capacity to speak with friends and family or experience Earth’s regular habitat can prompt pressure and psychological wellness issues.
Arrangement: Mental help and virtual reality
To alleviate the mental issues related with profound space travel, space explorers get broad mental preparation and backing. What’s more, computer generated simulation (VR) innovation can be utilized to make vivid encounters that mimic Earth-like conditions, assisting space travelers with adapting to disconnection and giving a feeling of association with their home planet.
5. Utilization of fuel and resources
Conveying adequate fuel for a profound space mission can be restrictively costly and testing. Depending entirely on Earth-provided assets isn’t maintainable for long haul missions.
Arrangement: In-situ Asset Usage (ISRU)
In-situ Asset Usage (ISRU) is a vital answer for the issue of fuel and asset use. ISRU includes mining and taking advantage of neighborhood assets at the objective, for example, water ice on the Moon or Mars, to deliver fuels, oxygen and other fundamental supplies. This diminishes the need to move all that from Earth and significantly decreases the expense of missions.
6. Microgravity Effects
Delayed openness to microgravity can prompt various medical issues in space travelers, including muscle and bone misfortune, cardiovascular issues, and conditions connected with liquid changes.
Arrangement: Counterfeit Gravity and Exercise Modes
Making fake gravity in a space apparatus through turning stations or rotators can assist with relieving the impacts of microgravity. Furthermore, space travelers follow severe activity regimens to keep up with actual wellbeing during long-term missions.
7. Independent route and communication
Profound space missions frequently include correspondence delays because of the immense distances included. This can make ongoing correspondence and route troublesome.
Arrangement: Independent Frameworks and AI
Profound space tests and shuttle are outfitted with cutting edge independent route frameworks that can settle on continuous choices in light of pre-customized calculations. Man-made reasoning (artificial intelligence) assumes a vital part in empowering independent frameworks to adjust to startling circumstances and keep up with correspondence joins with Earth.
8. Space Trash and Impact Avoidance
Space route is confounded by the presence of room trash, which represents a crash risk for shuttle.
Arrangement: Following and Aversion Systems
Space offices and associations all over the planet are creating modern global positioning frameworks to screen space trash and anticipate likely crashes. Moving capacities are additionally coordinated into space apparatus to keep away from crashes with garbage.
9. Manageability and ecological impact
Profound space missions can fundamentally affect the climate, both as far as the assets expected for the mission and the likely pollution of the extraterrestrial climate.
Arrangement: Moral Exploration and Insignificant Effect Protocols
Researchers and space organizations are focused on moral investigation, including severe planetary security conventions intended to forestall tainting of other divine bodies. Supportability endeavors additionally center around limiting the natural effect of missions.
10. Global cooperation
Profound space investigation is a worldwide undertaking and global participation is fundamental for the progress of mind boggling missions.
The arrangement: cooperative organizations
Space offices and associations all over the planet team up on joint missions and offer aptitude and assets. Global participation helps assemble assets, yet additionally advances serene collaboration in space investigation.
All in all, while profound space travel presents many difficulties, creative arrangements created by researchers and designers offer expect making our fantasies of room investigation a reality. From cutting-edge impetus frameworks to radiation protecting, shut circle life support, and mental help, mankind is effectively addressing the obstructions to profound space investigation. As we keep on stretching the boundaries of our comprehension and innovation, the possibility of sending space explorers on lengthy term missions to far off planets and past turns out to be always achievable. Profound space travel addresses a noteworthy excursion of human investigation, pushing the limits of our insight and capacities and holding the commitment of opening the secrets of the universe.


Solar Eclipse: As Seen by Celebs
Even the stars were in awe of the solar eclipse Sunday!
Celebs took to their Twitter accounts to share their experience of the rare "ring of fire" solar eclipse, in which the moon passes in front of the sun leaving only a bright ring around its edges. The continental United States won't witness another eclipse for five years, and stars like Demi Moore, Katy Perry and Sarah Hyland did not want to miss out!
Dark Shadows actress Chloe Grace Moretz shared a photo of her view of the solar eclipse.
Moore got in on the action, tweeting, "Solar eclipse anyone?" Modern Family star Hyland wrote, "Ouch. The solar eclipse hurts."
Glee star Chris Colfer was especially excited to witness the event. "Solar eclipse! Solar eclipse!" he tweeted. "Anyone else watching it through four pairs of sunglasses?"
Dancing With the Stars' Brooke Burke-Charvet tweeted a bright photo of the event to her followers.
American Idol host Ryan Seacrest asked, "Has anyone actually been blinded by the solar eclipse?" Perry joked, "Tonight's Billboard Music Awards performance is sponsored by the solar eclipse... #venus."
And comedian Dane Cook also used the opportunity to make a joke. He tweeted, "This solar eclipse looks strange to me. Maybe I looked at it too long??"

I put boots, a hoodie, and a scarf on to give me warmth. It was 37 degrees and midnight. I couldn’t resist. I went out and laid on the diving board of my pool. The sky tonight was beyond beautiful. The chill in the air was not enough to keep me away from gazing at the stars brilliantly shining. I simply needed to bask in the beauty. The stars honestly take my breath away. How could something so far away be so beautiful? How could something so extravagant have just happened? There has to be something more. As I continued to just ponder the questions of my life, I watched as slowly clouds rolled in. Unexpectedly, the stars were quickly hidden behind the sheets of gray clouds. I could have easily just went inside. It was cold, but I wanted to wait to see the stars some more. The glimpse I had was not enough. I waited. And I waited some more. For half an hour I waited, gently shivering in the cold, while the clouds moved out and the stars were revealed once more.
Oh what a beautiful parallel this is to my life and faith. God is such a beautiful God. I rarely, if ever, fully understand what is going on. As I watched the stars- then the clouds- I realized something about patience. God’s timing is far from what I can fathom. I do not like waiting for his answers and wisdom to come. But the end result is always beautiful. I have a promise of great things ahead- marvelous and wondrous things- that if I become stubborn and impatient, I will miss out on them all. It is not easy to wait. We each have our own midnight. We get distracted by a variety of things. Often people just forget that there is something beautiful coming and they give up. But it is at midnight, as these stars faded into the gray, I realized that I need to have hope. You need to have hope. There is something beautiful to come. Just wait for it. Don’t give up yet. The clouds are moving…just wait.
“Tell them to look up. Tell them to remember the stars…The stars are always there but we miss them in the dirt and clouds. We miss them in the storms. Tell them to remember hope. We have hope.”

This week, NASA is planning to launch a spacecraft that will purposely crash into an asteroid. At 10:20 p.m. PT (1:20 a.m. ET) on November 23, the DART mission, or the Double Asteroid Redirection Test, will launch from Vandenberg Air Force Base in California. The ceremony will be streamed live on NASA TV and NASA’s website.
Asteroid deflection technology will be put to the test in September 2022, when the spacecraft reaches its goal in the vicinity of a near-Earth object.
In order to reach Dimorphos, a tiny moon circling Didymos, the expedition will use the ion propulsion system on board the spacecraft. A full-scale demonstration of this sort of technology for planetary defence is being planned by the agency. According to the European Space Agency, this will be the first time humans have influenced the dynamics of a solar system body in a measurable way.
Asteroids and comets that pass within 30 million miles (48 million kilometres) of Earth are considered near-Earth objects. One of NASA’s key goals is to identify near-Earth objects (NEOs) that pose a hazard to Earth and its inhabitants.
“Didymos,” the Greek word for “twin,” refers to the asteroid’s binary system with the smaller asteroid or moon, which has a diameter of 525 feet (160 metres) and was identified two decades ago. As part of the DART team, Kleomenis Tsiganis of the Aristotle University of Thessaloniki recommended that Dimorphos be renamed “two forms.”
The DART mission should take place now. When Didymos and Dimorphos get close to Earth in September 2022, they will be within 6,835,083 miles (11 million kilometres) of us. According to Nancy Chabot, the DART coordination lead at the Johns Hopkins Applied Physics Laboratory (Laurel) in Maryland, the spacecraft will approach Dimorphos at around 15,000 miles per hour.
Autonomous navigation software, a camera on the spacecraft called DRACO, and the ability to identify and crash with Dimorphos will aid the spacecraft. Draco refers to Didymos Reconnaissance and an Asteroid Camera for OpNav.
This mission’s goal is to purposely collide with asteroid Dimorphos in order to alter its orbit, according to NASA. LICIACube, or Light Italian Cubesat for Imaging of Asteroids, a companion cube satellite funded by the Italian Space Agency, will record this crash. It’s the first deep space mission for the Italian Space Agency.
Before impact, the briefcase-sized CubeSat will be released from DART and begin recording. Three minutes after impact, a CubeSat will fly over Dimorphos and gather photographs and videos.
Elena Adams, a DART mission systems engineer at the Johns Hopkins Applied Physics Laboratory, expects the footage of the impact to be “very spectacular.”
NASA’s DART programme scientist Tom Statler said that astronomers will be able to compare images from Earth-based observatories before and after the kinetic impact to calculate how much Dimorphos’ orbital period altered. Asteroid response to deflection efforts will be determined by this measurement. “That’s the most important one.”
The European Space Agency’s Hera mission will revisit Didymos and Dimorphos a few years after the impact.
NASA’s Planetary Defense Coordination Office and the Johns Hopkins University Applied Physics Laboratory created DART, while Hera’s mission crew will collaborate on AIDA, a worldwide effort to study the impact and deflection of asteroids, as part of the AIDA project.
According to a NASA release, “DRT represents a first step in evaluating approaches for dangerous asteroid deflection,” DART programme manager Andrea Riley stated. Asteroids are a worldwide issue and our kinetic impact deflection demonstration is a great opportunity for us to engage with our Italian and European colleagues to acquire the most precise data possible.

I've always thought doing PR for space would be a pretty cool gig. Space has an enviable haul of mind-bending statistics and research proof points at its disposal, and a lorryload of show-stopping images to take us to galaxies far away—literally.
Outer space, perhaps more than any one brand, psyche, or moment in time, has the ability to stretch the limits of our imagination and humanity's potential. Really great stuff for PR, in other words.
Last week's first ever seen vision of a black hole, stitched together from telescopes around the world like some extraterrestrial tapestry, took the cake for one of my feel-good news moments of this year.
The hazy orange glow, like a candle being blown out in a dark room, opened up more questions than it answered, and, in true Twitter style, was quickly memeified, being compared to everything from Brexit to Krispy Kreme donuts.
The collective imagination capturing reminded me of the power of photography to distill our doubts and inspire rapture. Even in the age of high-resolution imagery, the world was not only satisfied but ecstatic with the rather blurry offering of the black hole.
Marketing is and should be tied to the power of imagery. As communications professionals, this is a timely reminder to always champion the visual in a world that's often predisposed to words.
But no one’s ever really seen a black hole—until now. Astronomers on Wednesday released the first direct image of a black hole, pieced together from observations by telescopes around the world.


In the wunderkammer, Maarten VANDEN EYNDE (b. 1977) shows The Earth seen from the Moon (2005), which combines two seemingly disparate elements: a military helmet and a telescope.
On the blue helmet of a UN soldier, Vanden Eynde has listed the names of the seas and craters identified on the visible surface of the Moon with an indelible marker. Through this work, the artist opens up various reflections on the fields of science, politics and ecology.
The history of the Moon is obviously linked to that of our planet since the most accepted theory of its creation is that of a planetary impact; the Earth would have been hit tangentially more than 4 billion years ago by an asteroid the size of Mars, throwing fragments of the asteroid and of the Earth into space. This debris would have gradually agglomerated, forming the Moon. The craters visible on the Moon have been called "lunar seas" and have been given Latin names with symbolic connotations or the names of ancient philosophers, scientists and also astronauts (the three Americans of Apollo 11 each have "their" crater).
The formal analogy between the helmet and a planet is quite clear. However, it is true that the helmet is half-spherical, but this should be compared with the fact that the Moon is only visible to Earthlings as a single face (due to the coincidence of revolution and rotation).
By transferring the names of the lunar spaces onto an object that is supposed to protect the human head during dangerous missions, Vanden Eynde emphasises that this helmet is dented and was therefore worn by a soldier (presumably on a peacekeeping mission somewhere on Earth), but also that it is a symbol of protection (of the head and, beyond that, of
peace between nations). Coming from all nations, the soldiers who wear this helmet are empowered to come to the aid of all populations. This solidarity can be applied metaphorically to the unbreakable bond between the Earth and its satellite.
The blue helmet also represents the political efforts to administer the world in a peaceful manner without ever succeeding. The names given by the Committee responsible for the terminology of the planetary system metaphorically illustrate this desire to achieve a result and their impossibility to do so: Mare Tranquillitatis, Mare Serenitatis but also Mare Crisium, Lacus Mortis (Lake of Death), Oceanus Procellarum (Ocean of Storms)...
Ultimately, this work makes us realise that in order to protect our cranium/planet, we should perhaps pay more attention to what is going on around us. The single viewpoint allows little understanding. The telescope is pointed at the helmet but doesn't really 'see' anything. While also a tribute to the great astronomers who have enabled mankind to advance in the understanding of the universe, the use of this instrument to observe distant objects is also a metaphorical way of referring to the difficulty of dealing with the world.
In this respect, the work is reminiscent of a passage from Bertolt Brecht's Life of Galileo (Leben des Galilei): 'The movements of the heavenly bodies have become more predictable; but still incalculable to the people are the movements of their rulers'.


The Color of the Milky Way… Some tips on best practice processing!
Wildlife and landscape photographers share one common goal: to show the beauty of nature as naturally and undistracted as possible. The Night Sky and celestial objects within – like the Milky Way – are considered an important part of nature, too. Careful editing of Night sky images is thus recommended if you want yourself to be considered a good astronomic landscape photographer instead of an artist. Here are a few hints on best practice for processing Milky Way shots.
It is widely agreed, that changing the natural colors of a sunset or landscape is considered some level of altering reality in wildlife / landscape photography. Not only the best photographers usually invest a considerable amount of time and workmanship for correctly color balancing their images, to preserve highlights, shadows, details as well as not to overdo contrast, saturation etc. You can do the same.
Everyone knows for example the fresh green color of a spring meadow from every-day experience, and actually most of us don’t want to have that altered unrealistic in nature photography. No nature photographer as well as most readers would like to see an image published in National Geographic or GEO, where the print does not represent the natural colors by the time the image was captured. Furthermore to make sure nature colors are preserved best, camera manufacturers push hard on their latest image processing engines, which preserve the last extra bit of original information in every RAW file for post processing, and good photographers take advantage of that information. There’s a lot of craftsmanship too at the stage of printing, to preserve the image colors as they were processed by the photographer.
If we now consider the Milky Way and the starry Sky as much a part of the natural world as flowers and grass, distorting its colors is – not only amongst Astrophotographers – viewed as unethical, unless it’s done with a declared aim of artistic expression, or for some other valid reason.
The night sky is a part of our surrounding nature, and it should be treated with the same care nature photographers do regarding natural colors in landscape astrophotography.
“Because, if you publish a photo of a blue sunset in landscape photography, it’s immediately clear that either there is something badly wrong with the camera/processing or you were the first human on Mars to see this view!“, says TWAN Director Babak Tafreshi, as described on the Sky&Telescope article, Capturing the Beauty of the Night Sky (read under “Natural Looking Sky Images”).
Tafreshi, a Lennart Nilson Priceholder*** for scientific photography, and founder of “The World at Night“ – a global IYA 2009 UNESCO program to make people aware of the beauty of the Night Sky – has processed thousands of starry sky images since he started Astrophotography over 20 years ago. Careful image preserving processing is also an important part at his Lectures during the Astromaster astrophotography workshops.
Tafreshi is indeed a bit worried about the flood of false-color, over-saturated, over-contrasted images of the Nightsky that pop the web these days. In fact, natural looking sky images even seem in defense in the age of facebook and social media. False colored or overcooked Images are getting more and more common on image sites like 500px and social networks.
But why are they so badly processed (except again, for maybe artistic reasons)?
It seems many photographers new to Astrophotography have not yet discovered, how Astronomers have researched and agreed with great care for many years, how the Milky Way should be reproduced in an image. A good starting point are the many outstanding images on the ESO site of the European South Observatory.
Second, many beginners in landscape astrophotography simply overcook processing with ramped up contrasts, weird color temperatures, over saturating their images (I did that too, in my early days).
Add to this the ever increasing problem of light pollution in many countries on earth (light polluted images are difficult to color correct), and you realize that most people have lost the sight of a natural looking night sky.
So, why then should they actually find images like these below wrong at all? They just don’t know it, but again, what about green grass that is now blue or red?
A good practice on processing, and some simple facts taken into consideration (see below), and things can improve a lot on a landscape astrophotography.
The worlds best Wildlife and Nature Landscape images not only capture the moment – they are all excellently processed. We as astrophotographers owe some patience and dedication to nature when we work on our images, especially on images of rare starry skies.
The ancient light of the stars has travelled millions of light years until it finally hits our retina as well as our camera sensors. Why throw stars away by over saturating and over contrasting images…
If you have a clear sky and photograph the Milky Way, how should the processing results look like? The following guideline and examples are provided by my colleague Babak Tafreshi:
1- The Milky Way is pale yellow (the colors change slightly along the plane)
Outstanding examples by Prof. David Malin*, inventor of film color astrophotography, from his Akira Fuji Collection (these are scanned film images, and the originals are impressive to look at):
An amazing story by itself about being closest to the stars, but also a beautiful, careful color processing of the Milky Way by TWAN member and ESO/Paranal Telescope Engineer Stephane Guisard:
A Milky Way image directly from the Alps (20 km from Innsbruck) – with a lot of light pollution low on the horizon from Northern Italy – so this image was not easy to process at all…
2- Notable stars should have colors that match their individual temperature range (if not white saturated by the sensor). If you capture red giant superstar Antares or Mars in blue, there is either a wrong calibration or something dramatic has happened to the star!
3- Sky background color (natural skyglow) in a dark site is (not accounting aurora and light pollution)
A) black pale green-red depending on airglow activity
http://www.eso.org/~sguisard/Pagim/darkest_sky.html (amazing example by Stephane Guisard)
http://twanight.org?ID=3003578 (stronger airglow appearance)
B) Blue when there is moonlight or twilight
Of course Astrophotographers often change color temperatures in processing to reduce the yellow-red cast of light pollution in the skyglow. There are also SkyGlow filters to avoid having to do so. But the Sky and Star colors should not go too much into the blue then.
4- Zodiacal light is white-pale blue
So, actually what is the bottom line? Well, don’t overdo it. Be careful on saturation, vibrance and contrast.
Especially as many processing hosts on the market today like Lightroom 4, are very agressive on saturation, contrast and vibrance – it seems they are actually optimized for daytime photography and need to be very carefully used on the processing of starry sky images. Too much saturation / contrast** can “eat stars”, too, the fainter stars disappear in your image easily.
Then another reason may be drastically non-color balanced screens, those false colored images may have been worked on. If you really consider to do much landscape astrophotography or nature photography in general: a calibrated screen helps a lot, and there are quite some good affordable color meters on the market. (tip: if you want to track the stars, to have them pinpoint on your images during longer exposures, a star tracker can be a great tool to improve your images).
Finally: While I do not consider myself the best astrophotographer, I always try to get my version of the Milky Way the best possible processing. Which is not always easy under a light polluted night sky.
At the end of the day, however, one thing is clear: the Milky Way isn’t green or red or totally magenta – nor is the night sky (except for Light Pollution – which – with Sodium Lamps below will add a orange cast to clouds etc).
So let’s keep trying to preserve the glowing beauty above us the best we can in our images – to give people and kids who are living in light polluted areas a natural view of one of the wonders of our world.
And if you want to see some Milky Way now – enjoy Astronomer’s Paradise. It’s dark, cold, but beautiful – Atacama Skies! “AP” as we also call it, is a huge international success and collaboration with my pal Babak Tafreshi of Twanight.org!
*I am not a relative to Prof. David Malin – Lennart Nilsson Priceholder and honorable inventor of film color astrophotography.
**for Timelapse short films I do increase contrast amongst other settings slightly a bit to have a more cinematic look, but for stills I try to avoid it.
***A bit comparable like the nobel price for photographers
