The Air Force Research Laboratory unveiled a component named Helios for its forthcoming Arachne spacecraft. Arachne, to be launched in 2024, is the main part of the Space Solar Power Incremental Demonstrations and Research (SSPIDR) project.
The Air Force reports:
“Arachne will demonstrate emerging technologies that support the ability to convert solar energy to radio frequency (RF) power, using innovative ‘sandwich tiles’ as well as the feasibility of transmitting that energy to the ground and converting it to usable power.”
