B-rool footage of Engineers test the Webb Telescope's ISIM structure on the large centrifuge at NASA Goddard Space Flight Center.
Webb Telescope's Integrated Science Instrument Module (ISIM) is tested on the very large centrifuge at the NASA Goddard Space Flight Center - May 2011.
The centrifuge simulates the increased feeling of gravity's pull during a launch. For astronauts, that's normally a few minutes at two or three times the force of Earth's gravity, measured in Gs. Equipment carried in space shuttle cargo bays usually sees between 6 and 7 Gs because of vibration.
