Engineers pose by NASA's James Webb Space Telescope shortly after it emerged from Chamber A at NASA's Johnson Space Center in Houston on 1 December 2017.
The telescope's combined science instruments and optical element recently completed about 100 days of cryogenic testing inside Johnson's Chamber A, a massive thermal vacuum testing chamber at the center.
