Please DO NOT edit our page!!!  18.The astronauts in the ISS breath oxygen from the process called electrolysis, which uses electricity from the ISS solar panels to split water into hydrogen gas and oxygen gas. They also keep oxygen in pressurized storage tanks. Eventually scientists hope to use plants to produce oxygen in space. -Emily

19. Right now, carbon dioxide is removed from the ISS by a machine on the Zvezda Service Module based on the material called "zeolite," which acts like a molecular sieve. That carbon dioxide is thrown out into space, and enigneers are currently trying to figure out ways to recycle it. -Neha

20. In space, there is no continuous water supply. Water has to be brought up to the ISS from Earth. Also, there is limited storage space for water on the ISS. On the ISS, the life-support system is designed to recycel as much water as possible. Even urine and the humidity in the air is recycled. Astronauts on the ISS have to be cautious about their water use and consumption. -Emily

21. In space, astronauts eat a lot of the food we eat on Earth! Some things, like fruit, can be eaten in their natural form, while others like macaroni and cheese require water. On the ISS, there are ovens for heating things but there are no refrigerators, so food has to be stored properly to avoid spoilage. Like us, astronauts eat three meals a day which provides them with vitamins and minerals. The packaging that the food comes in has to be thrown away in a trash compactor, like a trash can. Astronauts have a variety of foods to choose from, from chicken to coffee, to candy! -Neha In space there is no gravity. Having no gravity makes eating much more difficult. In space, some foods have to be eaten in speacial ways, such as sticking the food to the table or wrapping it in a special way.
