Chemical Engineer David Rinderknecht prepares the Orbital Syngas Commodity Augmentation Reactor (OSCAR) for thermal testing Jan. 26, 2021, at NASA’s Kennedy Space Center in Florida. The tests are in preparation for a scheduled suborbital flight test later this year facilitated by NASA’s Flight Opportunities program. The testing ensures the thermal environment of the payload won’t create additional hazards during flight and that OSCAR can successfully operate within the temperature range it may encounter as it performs tests in microgravity.
