What would happen to a human in outer space?
Blood and other bodily fluids are pulled by gravity into the lower body. When you go to space, gravity weakens and thus fluids are no longer pulled down, resulting in a state where fluids accumulate in the upper body. This is why the face swells in space.
Can human survive in outer space?
Space is very dangerous – and without protection, people would not be able to survive there. In space, there’s no air – so you couldn’t breathe. It’s cold – so you’d freeze. And there’s lots of nasty radiation (from the Sun, and from the rest of the Universe), so you’d get really, really bad sunburn.

Is anyone lost in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle.
Who is in space right now 2022?
The Ax-1 crew members, Commander Michael López-Alegría of Spain and the United States, Pilot Larry Connor of the United States, and Mission Specialists Eytan Stibbe of Israel and Mark Pathy of Canada, will travel to the space station on the SpaceX Dragon Endeavour spacecraft after launching on the company’s Falcon 9 …

What happens if you stay in space for 5 years?
Astronauts who have stayed in space for long periods have problems with their circulation and eyesight. That’s in addition to losses in bone and muscle tissue. Kelly has collected fluid samples and undergone rigorous medical testing to document these changes over the course of his trip.
Do you age less in space?
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

How is 1 hour 7 years in interstellar?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
