Life on the International Space Station (ISS) is different from life on Earth in many ways including:
The ISS is larger than a six-bedroom house, with six sleeping quarters, two bathrooms, a gym, and a bay window.
Astronauts work out at least two hours a day to prevent muscle and bone loss. They also have free time to read, listen to music, watch movies, and talk with friends and family.
Astronauts take sponge baths daily, using Rinseless shampoo and two washcloths. They also brush their teeth.
- Astronauts regenerate water by condensing moisture from the cabin humidity and recycling their urine.
- Astronauts need to minimize waste.
- The Environmental Control and Life Support System (ECLSS) uses solar-panel-generated electricity to split water into hydrogen and oxygen.
- Astronauts need to adapt their activities to the weightless conditions. They may experience dizziness, sleepiness, weakness, loss of appetite, and stomach upsets
- The ISS orbits the Earth 16 times in 24 hours, traveling at a speed of 5 miles per second. It has been continuously occupied since 2000.
