As there is less space , and three men share the craft the amount of space will be less.
Because it works much better for the purpose than a bicycle would.
Oxygen (O2) is necessary to the respiration and the survival of astronauts in the near vacuum of space. Astronauts does not have the breathable atmosphere on Earth in space. The space suit protects them from the lethal cold and vacuum of space by keeping him in temperature controlled and pressurized environment.
Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
Astronauts bring water into space by bottles and canteens. They strap these containers to the walls with Velcro so it won't float away. To see how much water they carry, see the related question below.
Most workers risks their lives for their job. Factory and refinery workers die at a much higher rate than astronauts. More astronauts have died in plane crashes and car accidents than have died in space. While being an astronaut seems more dangerous than most jobs, there are countless safety factors built into the spacecraft and the flight plan that don't exist in most other earthly workplaces. There's obviously a risk to space travel, but NASA and the astronauts make sure their vehicle is as safe as possible to minimize those risks as much as is humanly possible.

None None
maybe they brought a plant
no because they don't need that much energy <33
Astronauts are thoroughly trained before they go into space, so they are accustomed to living in a very restricted area, with not much room; they know how to make the most of every inch of the capsule. They are also taught how to keep everything tidy, how to clean up after they eat, and what needs to be stored-- some items they use in space will be tested when they return, because NASA wants to know what effect space travel has on a person's bodily functions and health. So, the astronauts use certain items and then bag them, so that NASA will get accurate test results later on.
Astronauts that work and live and the international space station can have a salary anywhere from $65,000 to $141,000 a year depending on the years of service.
You need to be trained and know what do in the Rocket in Space.
None they use carbon monoxide
they have a little amount of space inside of a module
How much fuel will be needed in a rocket will depend on the size of the rocket and where it is going. A rocket that will be traveling into space burns a lot of fuel and will need enough to keep it in orbit for teh desired time.
