What do astronauts do on the International Space Station?
What do astronauts do on the ISS? An astronaut’s primary job while on the space station is to conduct scientific experiments and maintain the space station. When not working, astronauts do a lot of the same things we do on Earth. Astronauts also complete a two-hour daily exercise program to remain fit.
What is the main purpose of the ISS crew?
The ISS was originally intended to be a laboratory, observatory, and factory while providing transportation, maintenance, and a low Earth orbit staging base for possible future missions to the Moon, Mars, and asteroids.
What jobs do astronauts have?

Does your head explode in space?
Humans don’t explode in space. According to Richard Harding’s book “Survival in Space,” the blood vessels can withstand the internal pressure without exploding. Humans do die if left in outer space without a space suit. But they die for the same reason as people who are left too long underwater: lack of oxygen.
How fast would you die on Mars?
Breathing on Mars In these conditions humans die within minutes unless a pressure suit provides life support. If Mars’ atmospheric pressure could rise above 19 kPa (2.8 psi), then a pressure suit would not be required.
Can you survive on Mars without a spacesuit?
The atmospheric pressure on Mars varies with elevation and seasons, but there is not enough pressure to sustain life without a pressure suit.
