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 bunny 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.

In an up-close photo taken in front of reflective solar panels made up of blue dots, two technicians in white bunny suits take measurements near the body of the JPSS-4 spacecraft, which is wrapped in orange mylar. From this angle, three cords hanging from the ceiling are visible, supporting the solar panels.

The JPSS-4 satellite’s solar panels, shown as four large square sections with blue dotted segments, appear fully unfolded and reflective. At the back of the image, the satellite bus is wrapped in orange mylar, while the panels extend outward in front. Several cords are visible on the floor of the testing chamber, connected to the spacecraft body.

The JPSS-4 satellite’s solar panels, shown as a short series of large squares with blue dotted segments, appear to be unfolding from the satellite body. About eight technicians in white bunny suits stand around the spacecraft, observing the deployment. At the back of the image, the satellite bus is wrapped in orange mylar, while the panels unfold in front of it.

JPSS-3 is visible in the foreground of the photo as a large rectangle covered in orange mylar with hardware attached. JPSS-4 is in the background of the photo, in the bottom left. It appears as a silver rectangle with wires and hardware attached. Both spacecraft are attached to white rollover fixtures. The satellites sit in a large, white room with rows of lights on the ceiling and a large observation window in the top, center of the photo. The room has a tan floor with black stanchions and black and y

In a large white clean room with a tan and white floor, the JPSS-3 spacecraft is seen inside of a dark, tubular chamber with rows of lights on the ceiling. A large, circular door is open to the left. The spacecraft is covered in silver and orange colored mylar. On the left, in front of the chamber door, a group of 12 individuals are standing and talking while wearing white bunny suits. Yellow railing sits on both sides of the chamber opening.

The silver and orange mylar-covered JPSS-3 satellite sits inside the chamber while a person in a white bunny suit works on the right side of the spacecraft. Outside of the chamber there is yellow railing on both sides of the tube. There are silver pipes attached to the wall next to the chamber opening. Outside of the chamber, there is a tan and white floor, silver carts and tables.

The JPSS-4 spacecraft appears as a silver rectangle in the center of the image with wires and hardware attached to the silver panel. The spacecraft is attached to a white, rotating fixture and sits in a white room with an observation window in the top, center of the image. The room also contains metal crates, a desk, a chair, trash can, and metal stepping stool.
