Webb Telescope to be Tested in Upgraded Thermal-Vacuum Chamber
Added Jan 28, 2013 | Rate View top rated
When the next-generation space telescope was being designed, engineers had to ensure there was a place large enough to test it, considering it's as big as a tennis court. That honor fell upon "Chamber A" in the thermal-vacuum test facility at NASA's Johnson Space Center. The testing chamber, which was used during Apollo missions, has now been upgraded and remodeled to accommodate testing the James Webb Space Telescope. Chamber A is now the largest high-vacuum, cryogenic-optical test chamber in the world. Testing will confirm the telescope and science instrument systems will perform properly together in the cold temperatures of space. Additional test support equipment includes mass spectrometers, infrared cameras, and television cameras so engineers can keep an eye on the Webb while it's being tested.
