Waspie_Dwarf Posted June 16, 2014 #1 Share Posted June 16, 2014 Webb's Fully Integrated 'Heart' Lowered into the Chamber Engineer Jack Marshall held his breath. The "heart" of the James Webb Space Telescope hung from a cable 30 feet in the air as it was lowered slowly into the massive thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland.This "heart" of Webb is called the ISIM or Integrated Science Instrument Module, which along with its thermal vacuum test frame and supporting hardware, weighs about as much as an elephant. Within this test frame, ISIM sits inside a big-mirrored cube of cryo-panels and blankets. This process can be seen in a video by a Goddard videographer.
