Moonlighter is a joint project from the Aerospace Corporation, Space Systems Command, and the Air Force Research Laboratory that will let good guy hackers look for vulnerabilities in satellites while in orbit and come up with better solutions to harden space assets.

“This was kind of conceived to help bridge the gap between the cyber community and the space community because you can envision different cyber defense theories and ways to approach things to make them more cyber resilient, but there’s been a really limited ability to do things in space,” Debra Emmons, CTO at the Aerospace Corporation, told Payload. “This will be the world’s first and only hacking sandbox in space.”
