The vacuum of Space would cause hydrogen bubbles to form in there blood, knocking them unconscious then killing them.

Air, food, and water, same as on Earth.
You'd need an atmosphere similar to that of Earth's, a source of water similar to that of Earth's and land masses that have the ability to grow food on them, similar to that of Earth's. Basically, you'd need Earth.
They need air and an atmospheric pressurized environment.
It is earth
They have try to last as long as they can until they return to Earth.
Astronauts need water to maintain hydration, which is crucial for their overall health and physical performance in the microgravity environment of space. Water is essential for various bodily functions, including temperature regulation, digestion, and waste removal. Additionally, it is used for food preparation and can be recycled in spacecraft to minimize waste. Proper hydration helps astronauts cope with the physical demands of space missions and supports their well-being during extended periods away from Earth.
There are two main reasons; the gravity is 1/6 of Earth's so astronauts tended to bounce along. Conversely, to survive on the moon, astronauts are carrying a large backpack and wearing a bulky spacesuit - which doubles their weight; you can see the affect of the weight as the astronauts tend to lean forwards.
Astronauts will need to take air to Mars because the Martian atmosphere is thin and mostly carbon dioxide, making it unsuitable for human breathing. Bringing air from Earth ensures that astronauts will have a breathable atmosphere during their mission on Mars.
Yes, due to the lack of atmosphere and moisture on Mars, astronauts walking on the surface may accumulate a static charge similar to what can happen on Earth. This could potentially lead to issues with equipment malfunctions or dust clinging to their suits. Precautions will need to be taken to mitigate these risks.
Astronauts need an air tank to supply them with oxygen to breathe in the airless environment of space, where there is no atmospheric pressure to support life. The air tank also helps regulate the pressure inside the astronaut's suit and provides a way to expel carbon dioxide.
It's the same reason you can only see one side of your head when you look in a mirror. The astronauts would need a mirror to see round the back.
Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
