PBR (Photobioreactor)

iss059e092376 (6/6/2019) --- NASA astronaut Anne McClain is photographed onboard the International Space Station (ISS) using the Liquid Exchange Device. The documentation was taken during the filling of the Photobioreactor (PBR) with medium and algae to begin the experiment. The Photobioreactor investigation aims at demonstrating that microalgae (i.e. biological processes) can be used together with existing systems to improve recycling of resources, creating a hybrid life support system. This hybrid approach could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth.
