Webb Telescope's Backplane Pathfinder Arrives at NASA JSC for Cryotesting
Webb Telescope's Backplane Pathfinder arrives at Ellington Field Joint Reserve Base in Houston. Engineers will test Pathfinder inside NASA's largest cryogenic vacuum chamber called Chamber A. NASA engineers off-load pathfinder and its shipping container from a US Airforce C-5 cargo plane and tranport it to the Johnson Space Center and into Chamber A's cleanroom.
