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.

A large, tubular champer sits open in a large, white clean room with its white door seen on the left against a white walll. 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 wit

The silver and orange mylar-covered JPSS-3 satellite sits inside the chamber while two individuals work in front of the chamber. Yellow railing sits on both sides of the chamber opening. Silver pipes are attached to the wall on the right side of the chamber. A silver cart with red wires attached sits directly in front of the spacecraft.

A large, tubular chamber sits open in a large, white clean room with its white door seen on the left against a white wall. The silver and orange mylar-covered JPSS-3 satellite sits inside the chamber while five individuals in white bunny suits work around the spacecraft. Three people are directly in front of the spacecraft around a silver cart with red wires attached. One stands in front of the spacecraft to the right side and one other is working inside the chamber on the right side.

In the center of the photo, the spacecraft covered in silver and orange mylar sits just outside of a large, tubular chamber. Three individuals in white bunny suits work on the spacecraft in a large, white clean room. Silver pipes are attached to the wall to the right side of the open chamber and on the left side, the open white door to the chamber is visible. Yellow railing sits on both side of the chamber. In the foreground of the photo, yellow and black tape hangs to close off the area and a desk.

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

JPSS-3 and JPSS-4 are shown side-by-side at the Northrop Grumman Spacecraft Facility in Gilbert, Arizona in October. The JPSS-3 zenith panel is in the foreground of the photo, while the nadir deck of JPSS-4 spacecraft bus is visible in the…
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.

The JPSS-4 spacecraft bus appears in the center of the image as a silver rectangle with wires and hardware covering the surface while a person in a white, bunny suit works towards the right-hand end of the spacecraft. The satellite is attached to a white, rotating fixture in a white room with florescent lights lining the ceiling. A blue desk with two chairs and a monitor sits in the bottom center of the image. Two green, rolling tables also appear in the bottom of the image.
