JWST begins unfolding delicate, massive sunshield
On Tuesday (December 28), the James Webb Space Telescope notched another key step in its deployment as it unfolded the Forward Unitized Pallet Structure (UPS) of its vast sunshield, according to a NASA statement. The process took four hours and concluded at 1:21 p.m. EST (1821 GMT), according to the agency. Webb will now mimic that process with the Aft UPS.
