Calibration exposure acquired with NIRSpec in Multi-Object Spectroscopy (MOS) mode during OTIS testing in 2017. The image was produced by sending commands to open over 100 of the instrument's microshutters.
JWST is being rolled-out of the enormous cryogenic chamber at NASA’s Johnson Space Center in Houston, where, in the previous months, it underwent comprehensive testing at temperatures similar to those of the environment at L2.
JWST is being prepared to enter the enormous cryogenic chamber at NASA’s Johnson Space Center in Houston, where it will undergo comprehensive testing at temperatures similar to those of the environment at L2.
The primary mirror of JWST is being carefully inspected before the start of the acoustic and vibration tests that the telescope together with the scientific instruments will undergo in the coming months.
JWST payload module (called ISIM) is being slowly and carefully lowered for its installation on the back of JWST's telescope (seen face down in this picture).
