A high-angle view looking down into a brightly lit, spacious cleanroom. The JPSS-3 and JPSS-4 satellites are seen side-by-side, both heavily wrapped in golden-orange thermal insulation and are mounted horizontally on heavy-duty white metal stands. One satellite is prominently in the foreground, while the second sits just behind it. Wires, cables, and small sensor components protrude from the gold wrapping.

At the back of the JPSS-4 satellite’s solar array, four black panels with visible circuitry paths are seen from behind. Near the JPSS-4 satellite bus, which is wrapped in orange mylar, a technician in a white protective cleanroom suit stands on a ladder being handed tools by another as they take measurements on the spacecraft. Several supports extending from the ceiling are clamped onto the tops of the panels.
