CSS employee owners supporting NASA recently completed an upgrade of a new cold plate for Solidification Using a Baffle in Sealed Ampoules (SUBSA) ground unit. The Cold Plate is a piece of ground support equipment (GSE) that helps control the temperature of the SUBSA furnace for ground testing, similar to the Cold Plate in the Microgravity Science Glovebox (MSG) onboard the International Space Station.

Preparing and Delivering Samples for Travel to the International Space Station

CSS employee owners on contract with NASA delivered six newly prepared Solidification Using a Baffle in Sealed Ampoules (SUBSA)—a high temperature furnace with temperature and timing control for melting samples to create different materials and alloys—samples for the NG-23 launch, which took place on September 14, 2025. On this mission, samples are being delivered for…

Installing Environmental Monitoring Stations

Our field crews installed/updated two environmental monitoring stations in remote locations in the Pacific Northwest. Multiple types of sensors were installed including air and soil temperature, precipitation, soil moisture and soil redox potential. These stations provide data for designing and evaluating soil remediation projects for U.S. Environmental Protection Agency’s Office of Research and Development. Installing…
