B-roll video of Webb Telescope’s ISIM structure being removed from the large cryogenic vacuum chamber at NASA Goddard Space Flight center, called the Space Environment Simulator (SES). After ISIM is lifted out of the vacuum chamber, engineers move the wrapped ISIM structure into the clean room.
The Webb Telescope completes a major test milestone designated CV2 (Cryogenic Vacuum test 2). This test examined the heart of the Webb Telescope, it’s full flight ISIM assembly. This test included all four of Webb’s science instruments (FGS/NIRISS, MIRI, NIRCam, and NIRSpec) with their associated warm electronics boxes and flight harnesses. The more than three month long test inside NASA Goddard Space Flight Center’s Space Environment Simulator subjected the structure and instruments to the vacuum and cryogenic temperature they will be operating in during the mission. CV2 is the first opportunity to assess the health and functionality of Webb’s ISIM as a whole at its cryogenic operating temperature.
