NOAA's JPSS-1 Satellite Solar Array Successfully Completes Deployment Testing
The solar panel array on NOAA's polar-orbiting satellite JPSS-1 spacecraft successfully completed deployment testing at Ball Aerospace and Technologies Corp. in a cleanroom facility near where the JPSS-1 satellite is undergoing integration and test.
Engineers unfurled the three panels of the solar panel array on a special friction reducing floor that helps simulate deployment in the zero-gravity environment of space. The solar array is folded up at launch and deploys on orbit, resembling a giant black wing and generating more than 2775 watts of power for NOAA's JPSS-1 satellite. Photovoltaic cells in the solar array derive electricity from sunlight and convert solar radiation into direct current electricity. The JPSS-1 photovoltaics in the solar panel array will power the entire satellite including all of the instruments, computers, data processors, and telecommunications equipment.
The Joint Polar Satellite System (JPSS) is the Nation's next generation polar-orbiting operational satellite system. JPSS is a collaborative program between the National Oceanic and Atmospheric Administration (NOAA) and its acquisition agent, National Aeronautics and Space Administration (NASA). This interagency effort (JPSS) is the latest generation of U.S. polar-orbiting satellites.
