Photobioreactor: oxygen and a source of nutrition for astronauts

By [email protected] - 1st July 2019 - 10:40

Airbus is bringing another experimental system to the International Space Station (ISS) in the form of the photobioreactor (PBR). The PBR, developed by the University of Stuttgart and built by Airbus on behalf of the German Aerospace Center is designed to convert part of the CO2 extracted by the ‘LSR’ Life Support Rack on board the ISS into oxygen and biomass, which could help to save valuable resources during future long-term missions into space. Future human research missions are expected to take astronauts to the Moon and Mars. A deciding factor for the success of these missions will be keeping the resources carried to a minimum. As it is both difficult and expensive to send new supplies from Earth, the greatest possible closure of the respective resource cycles for water, oxygen and food is of vital importance. Most waste water is already reprocessed into fresh water on the ISS.www.airbusdefenceandspace.com
