KIRTLAND AIR FORCE BASE, N.M. (AFRL PR) – The Air Force Research Laboratory’s and Northrop Grumman’s Space Solar Power Incremental Demonstrations and Research (SSPIDR) Project have successfully conducted the first end-to-end demonstration of key hardware for the Arachne flight experiment.

A ground demonstration of novel components for the “sandwich tile” were used to successfully convert solar energy to radio frequency (RF) – a fundamental step required to pave the way for a large-scale solar power collection system in space.
