IT'S ALIVE... well, it now has its power source! ⚡️The Nancy Grace Roman Space Telescope's power distribution unit, or PDU, has been installed into the spacecraft's primary structure.

This unit is the primary power source for the entire observatory and will draw energy from the solar array sunshields. #NASAHalloween #NASARoman

Image description:
1: A person in a white head-to-toe suit and blue gloves stands to the left of a device that looks like Thor’s hammer. The device is suspended horizontally from hanging metal rods. Behind the person and device, a metallic box-like structure rests on a gray table with wheels. The side of the structure appears to be covered in blue-tinted square and rectangular windows with rounded edges. Additional people, all in head-to-toe white suits and blue gloves, stand to the side of the structure – two at the left, observing the structure, and three at the right looking at a panel that has hinged outward from the structure. Its edges are covered in wires.
The wall at the left is covered in a grid of pink squares and the large room is brightly lit from lights on the high ceiling. Colorful wires snake across the white floor from the foreground to beyond the structure.

2: Four people in head-to-toe white suits and blue gloves are standing in front of a metal box-like structure. There is a hinged door on the structure that is opened from the right side. The interior of the hinged door is covered in metallic boxes with many connected wires. Inside the structure lots of wires are dangled in front of a silvery metallic object that has a raised diamond like pattern.
The person on the left is pushing a horizontal device that looks like a hammer towards the open panel. The device is suspended by hanging metal rods. In the background at the left, a wall is covered in small, salmon-pink squares. At the back right, a light blue staircase criss-crosses upward. A wide viewing window is on the back wall behind the structure and people.
