Astronauts must be supplied with air, water and food whilst in space. In order to recycle these vital resources over a long period of time and to make them available for several years, closed life support systems are needed. Eu:CROPIS was a biological life support system experiment to test the long-term stability and self-sustainability of a biological life support system for missions to the Moon or Mars. The satellite was launched on December 3, 2018 and was successfully operated with the AOCS working as planned.
