Composite Crew Module Undergoes Vacuum Testing at Marshall

Huntsville, Ala. (NASA PR — This week, engineers at NASA’s Marshall Space Flight Center in Huntsville, Ala., moved a Composite Crew Module (CCM) into the Environmental Test Facility vacuum chamber to gauge how well a space structure fabricated with composite materials will react in a simulated space environment.

Huntsville, Ala. (NASA PR — This week, engineers at NASA’s Marshall Space Flight Center in Huntsville, Ala., moved a Composite Crew Module (CCM) into the Environmental Test Facility vacuum chamber to gauge how well a space structure fabricated with composite materials will react in a simulated space environment. Data gained during this test series will aid in the design and development of future in-space composite habitable structures.
During the vacuum test, the chamber is sealed and purged to a level a vehicle would encounter on orbit to evaluate the composite material’s integrity. The crew module is filled with helium gas to allow engineers to detect any leaks that may occur as pressure increases. Vacuum testing will ...
