NASA Now Has Half of all Webb Telescope's Primary Flight Mirrors

Three primary Webb telescope mirror segments sit in shipping cannisters and await opening. A mechanical integration engineer and technicians vent and prepare the mirror canisters for inspection. The mirrors have arrived at their new home at NASA, where they will be residing at the giant cleanroom at Goddard for a while as technicians check them out. Previously on Sept. 17, 2012, two other primary mirror segments arrived at Goddard and are currently being stored in the center's giant clean room.
