ALT Photo taken outdoors near a grassy field and waterway. A person’s arm extends from the left side, holding a purple NASA pass or ticket. In the background, a billboard displays an image of the Nancy Grace Roman Space Telescope with text naming the mission. An American flag on a tall pole stands to the right, and a partly cloudy sky fills the background.

ALT Side view of Roman's optical telescope assembly. The assembly looks like the tip of a dull pencil. The primary mirror is a shiny, silver circle, like a CD. Six black struts extend from the edge of the primary mirror to a black cylinder, which houses the secondary mirror.

ALT Inside a large, arched cargo bay with ribbed metal walls, a wide circular spacecraft structure sits centered on a platform. Crates, equipment, and workstations line the walls, and bright light pours in from the open end of the bay in the background. Several workers stand near the equipment along the sides of the space.

ALT The integrated Roman Space Telescope in Goddard’s large white clean room. Six large red solar panels covered in black squares lined up in three columns next to each other are opened up on the observatory. Two people in head to toe white clean room jumpsuits are standing to the left of the telescope, looking up at it.
