IMAP Solar Array Installation and Testing

Technicians at the Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida conduct illumination testing on Friday, July 18, 2025, by flashing a bright light that simulates the Sun into the two-panel solar array that will help power the agency’s IMAP (Interstellar Mapping and Acceleration Probe) observatory on its upcoming journey to a destination about one million miles away from Earth Lagrange Point 1. Each panel of the solar array, located on the top of IMAP, consists of 16 strings of solar cells, with 36 cells per string, and combined will convert sunlight into 500 watts of power, more than enough for the observatory, which as a system uses less power than five 100-watt incandescent light bulbs.
