Project Diana

Project Diana, named for the Roman moon goddess Diana, was an experimental project of the US Army Signal Corps in 1946 to bounce radar signals off the Moon and receive the reflected signals.[1] This was the first experiment in radar astronomy and the first active attempt to probe another celestial body. It was the inspiration for later Earth–Moon–Earth communication (EME) techniques.
