Summary
[edit]| Description |
The Webb telescope's Integrated Science Instrument Module (ISIM) Structure is undergoing tests at NASA's Goddard Space Flight Center in Greenbelt, Md. In this photo, the ISIM was placed in a "Helium Shroud" that was placed into the Space Environment Simulator (SES) Chamber. The SES is a big vacuum chamber where scientists and engineers cryo-tested the ISIM and lowered the temperature of the structure to 42 Kelvin (-384.1 Fahrenheit or -231.1 Celsius) and below to ensure that it can withstand the frigid temperatures of space. A specially designed camera can be seen hanging from the ceiling. The engineer in this image is Paul Cleveland of NASA Goddard.
