Can astronauts maintain an ecosystem in space? A new experiment is trying to find out.
The Space and Technology Institute of South China, which is based in Shenzhen, will do an experiment to study ecological recycling in a space capsule.
Four people will live in a simulated space capsule for 180 days without any supplies from the outside. They will use an already supplied amount of water and oxygen to maintain an ecosystem.
The capsule is finished and the experiment will start this year.
Shenzhen plans to encourage the development of space-related technology from 2013 to 2020.
