Trent Tresch and Kai Staats work to remove 30+ years of rust and corrosion from the upper steel framework of the lung for the Test Module. This structure, built in 1987 as an engineering prototype for the Biosphere 2, includes a flexible, sealed membrane such that once inflated it maintains a positive pressure and provides an air buffer for the greenhouse structure.
When fully rebuilt, this will be attached to a corridor, workshop, and full crew quarters as the construct of a Space Analog for the Moon and Mars, or SAM at Biosphere 2.
