Space Force X-37B mission to test power beaming

When a Boeing-built X-37B space plane is sent into orbit this month for the test program’s sixth flight, it will try out a technology that’s been more than a decade in the making: space-based solar power.

An experiment designed by the U.S. Naval Research Laboratory will transform solar power into a microwave beam, potentially for transmission to the ground. If such a power-beaming system could be perfected, concentrated microwave energy from space could conceivably be converted to electricity for far-flung military outposts.

Back in 2007, the Pentagon issued a report saying the U.S. military could be an “anchor tenant customer” for space-based power generation systems. That report piggybacked on a NASA study that was written a decade earlier, assessing the feasibility of wireless power transmission from space.
