The solar panels reach their full width of over 14 feet (4.3 meters), and with the Deployable Aperture Cover standing tall, this observatory towers over 42 feet (12.8 meters) high –– taller than any other telescope created at NASA's Goddard Space Flight Center.This is the first drone footage captured inside a NASA cleanroom, fitting for Goddard's largest telescope. || ",

These final checks demonstrate that the solar panels and Deployable Aperture Cover operate flawlessly, ensuring the observatory is ready for the demands of spaceflight.The mechanisms that drive these deployments are not engineered for gravity, where even large structures move with minimal resistance. The cleanroom’s airflow pushes against the broad surfaces of the solar panels and aperture cover, placing added stress on their hinges. To compensate, engineers conduct these tests behind a temporary plastic windscreen, carefully positioned and lifted into place by a crane.The Deployable Aperture Cover requires a weight-offloading system to operate here on Earth. Cables are attached to a network of pulleys and chains, effectively counteracting gravity and allowing the structure to move as it would in space. || ",

These timelapses capture that slow and steady pace with long-exposure images stitched together to highlight the continuous work behind the scenes.In much the same way, the telescope itself will stitch together vast numbers of exposures into sweeping scientific surveys. By observing millions of stars over time, it will track changes across the cosmos capturing exploding stars, belching black holes, neutron star mergers, and more phenomena as they unfold. || ",

Now the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will begin joining the payload to the spacecraft.The telescope and instruments were mounted to Roman’s instrument carrier and precisely aligned in the largest clean room at Goddard, where the observatory is being assembled. Now, the whole assembly is being attached to the Roman spacecraft, which will deliver the observatory to its orbit and enable it to function once there.In the footage below technicians carefully lift the outer portion of the telescope, called the OSD or Outer Barrel, SASS, Deployable Aperature Cover, and place it over the internal half. Long guard rails keep the two halves in perfect position. The solar panels open shortly after the two havles joined, marking a nearly deployed and fully assembled observatory. || ",
