Johnson Space Center’s Chamber A is a 16.8 m (55 ft) diameter x 27.4 m (90 ft) high, thermal-vacuum test facility and is famous for testing the Apollo spacecraft, with and without the mission crew. Its usable test volume and high-fidelity space simulation capabilities are adaptable for thermal-vacuum testing of a wide variety of test articles, including entire space vehicles. In this photo employees and media get a chance to see the Chamber prior to the addition of a clean room built around the 40-ton door for testing of the James Webb Space Telescope in 2013. Chamber A, has already been equipped with instruments to measure and evaluate the shape and focus of the telescope's mirrors.
