hello space lovers
spaceX Is only company that is  revolutionizing the space industry
because first reusable rocket officially launched by  spacex only
and most beautiful rocket falcon9 rocket
and world had never seen such a beautiful landing in history
may be spacex is taking us first step for the type 1 civilization
so till now SPACEX launched only satellites
but for the first time spacex sending Humans to the space
in their own vehicle
may 27th 2020 is launch day
two astronauts  are going to ISS From kennedy launch station
now a days human landing to the ISS Is very common thing but spacex launching is not common thing
because Nasa space shuttle is disaster and few astronauts died in their own space shuttle
so from 2011 NASA sending their astronauts to ISS from russia soyuz capsule
and NASA paying 80 million Dollars for 1 seat in soyuz capsule
so to overcome this problem SPACEX came up with the dragon capsule
this is most advanced crew capsule in the world
because space shuttle having 2000 switches to operate by the astronaut
but this crew dragon had touch screen monitors and automatic system
so it Reduces the risk of operating space capsule
but still it's risky to fly first time on this crew dragon
this mission named Demo 2
after successful launch of Demo mission which is launched by putting dummy astronaut in it
and it docked to ISS and landed safely on  ocean
so NOW SPACEX And nasa sending astronauts in Demo 2  mision
this crew dragon is going to dock with the ISS
Some people may think is crew dragon safe
because APOLO Days two astronauts died in their crew capsule due to short circuit
so if the rocket blasts before liftoff
astronauts can't escape from that
if this happens crew dragon have own liquid boosters in it
so it could easily escape from rocket
then astronauts will easily separate from rocket
which is called Pad abort system
SPACEX successfully crossed pad abort test
in Gemini 6A Rocket, astronauts used this technique few seconds before engine starts
two astronauts escaped In this incident
olden days, to escape the astronauts
solid rocket boosters was placed on top of the crew module
you can observe here
astronauts will be escaped by using this boosters in emergency time
ISRO also Using same technology in Gaganyan mission
ISRO Already conducted pad abort test successfully
but spacex using liquid propulsion system to escape from rocket
because drogon capsule initially designed to land directly without help of parachute
but spacex not using this technology now
Because SpaceX Dragon should be certified by NASA
So spacex announced that we are not using direct landing due to astronauts safty
and spacex is developing more advanced landing system
spacex thought we can easily land on mars with this landing system
but NASA Stopped  spacex
 
NASA SLS Rocket also using solid rocket boosters
and most of the people waiting for the gaganyan mission
and may be it will be delay due to corona crisis
here is spacex team recent reharsals
space suits are looking more advanced and stylish
hand gloves are made to use touch screen monitors
which is having internal cooling system
and have inbuilt communication system
weight of this space suite is 21kg
neil armstrong space suite weight was 80 kg after ENTERING INTO space it becomes less weight
SPACEX Designed different space suite than the older model
so finally may 27th launch date
space lovers will definitely watch the liftoff
