The mission is part of a comprehensive investigation into prospective terrestrial use of solar energy captured in space.

The hardware is the first orbital experiment designed to convert sunlight for microwave power transmission for solar power satellites. (U.S. Naval Research Laboratory) The experiment is chugging along, and continues to operate and provide a bounty of flight data. ....
Scientists working for the Pentagon have successfully tested a solar panel the size of a pizza box in space, designed as a prototype for a future system to send electricity from space back to any point on Earth. The panel known as a Photovoltaic Radiofrequency Antenna Module (PRAM) was first launched in May 2020, attached to the Pentagon s X-37B unmanned drone, to harness light from the sun to convert to electricity. The drone is looping Earth every 90 minutes. The panel is designed to make best use of the light in space, which doesn t pass through the atmosphere, and so retains the energy of blue waves, making it more powerful than the sunlight that reaches Earth. Blue light diffuses on entry into the atmosphere, which is why the sky appears blue. ....
