LINUSS 2, the companion satellite to LINUSS 1, completes a pair testing navigation technology for LunaNet — NASA's planned lunar positioning network intended to give future Artemis missions the same reliable GPS-like navigation on the Moon that's taken entirely for granted on Earth. Testing this kind of technology in Earth orbit first, before ever committing it to an actual lunar mission, is standard practice — cheaper to fix a bug 310 miles up than 236,000 miles away.
