NASA says there is a problem with one of Lucy’s solar panels. The panel may not have deployed correctly, but it is still producing power and the other panel is working normally:
After successful separation from the rocket on Oct. 16, NASA’s Lucy spacecraft deployed both solar arrays. Soon after deployment, NASA received confirmation that one of the solar arrays was fully deployed and latched. Analysis currently shows the second solar array is partially unfurled. The team continues to look at all available engineering data to establish how far it is deployed. That solar array is generating nearly the expected power when compared to the fully deployed wing. This power level is enough to keep the spacecraft healthy and functioning.NASA Team Remains Focused on Lucy’s Solar Arrays, NASA
They’re still working on it. No word yet on whether this could potentially affect the mission itself.
