The development of the Space Environment Viability of Organics (SEVO) experiment aboard the Organism/Organic Exposure to Orbital Stresses (O/OREOS) satellite

► O/OREOS is the Organism/Organic Exposure to Orbital Stresses nanosatellite. ► O/OREOS includes the Space Environment Viability of Organics (SEVO) instrument. ► SEVO is now exposing four types of organic thin films to the space environment. ► Samples are contained in reaction cells that define four sets of reaction conditions. ► A spectrometer uses the Sun as the light source to monitor film evolution in situ.
