Astronauts on the space station have a controlled climate with heating systems to regulate temperature. They also wear special clothing that helps to maintain their body heat. Additionally, the station has insulation to minimize heat loss.
In a space station, astronauts conduct experiments, research microgravity effects on the human body, test new technologies, observe Earth from a unique perspective, and perform maintenance tasks to keep the station operational. They also exercise to combat muscle and bone loss caused by extended time in microgravity.
During a spacewalk, the International Space Station continues to orbit Earth at the same speed. Astronauts inside the space station remain weightless due to being in freefall, while astronauts outside the station are also in freefall but are carrying out tasks in the vacuum of space. The velocity of the space station is carefully maintained to keep it in orbit.
Astronaut beds on the International Space Station are small sleeping compartments with walls to keep the astronaut from floating around while they sleep. They typically have sleeping bags that are attached to the wall to keep them in place. Astronauts sleep in a sleeping bag that is strapped to the wall inside the compartment to keep them from floating around.
Astronauts sleep in sleeping bags that are attached to walls, floors, or ceilings in space capsules or onboard the International Space Station. They may use straps or Velcro to hold themselves in place since there is no gravity to keep them from floating around. Eye masks and earplugs can also help block out light and noise in the microgravity environment.
