After successfully clearing its final thermal vacuum test, which was designed to ensure Webb will function electronically in the vacuum of space, engineers meticulously sealed it in a special tent for transport between facilities within Northrop Grumman in Redondo Beach, California.
Webb currently exists as two halves – the spacecraft and the telescope. They’ll soon be integrated into one final observatory, but first the half containing Webb’s “brain” and sunshield (called the Spacecraft Element) needed to finish thermal testing.
