On Aug. 7 and 8, NASA’s Nancy Grace Roman Space Telescope team assessed the observatory’s solar panels and a visor-like sunshade called the deployable aperture cover — two components that will be stowed for launch and unfold in space. Engineers confirmed their successful operation during a closely monitored sequence in simulated space-like conditions. On the first day, Roman’s four outer solar panels were deployed one at a time, each unfolding over 30 seconds with 30-second pauses between them. The visor followed in a separate test the next day. These assessments help ensure Roman will perform as expected in space. Roman is slated to launch no later than May 2027, with the team working toward a potential early launch as soon as fall 2026.
