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).
A rare view of the completely uncovered JWST primary mirror with the unfolded secondary mirror structure, in the large clean room at the NASA Goddard Space Flight Center.
