Astronauts' Unique Challenges and Innovations in Space
- Astronauts use big elastics on their hips and shoulders to stay on the treadmill in space, along with a resistive machine for exercise.
- They keep a towel nearby to manage sweat, which is then velcroed to the wall to evaporate and collect as drinking water.
- Astronauts maintain their weight and muscle mass in space but may lose bone density, risking hip fractures upon return to Earth.
- Astronauts went to the moon as part of a Cold War challenge, with only 12 walking on the moon and 24 orbiting it.
- Astronauts train underwater to simulate weightlessness, using the buoyancy of water and the weight of suits.
- Twelve astronauts have walked on the moon, with communication in space involving transmitting signals through various systems.
- Astronauts slow down to return to Earth by using the drag of the atmosphere and landing either on water or land with various methods.
- Astronauts manage bodily functions in space by adapting to weightlessness, using airflow to direct waste into a sewage system.
- Waste is processed into drinking water, with solid waste stored and eventually disposed of by burning up in the atmosphere.
