Possible Discovery of Lost Spacecraft in Lunar Orbit.

The fate of the Lunar Module ascent stage, Eagle, from the Apollo 11 mission has long been presumed to have crashed into the lunar surface. However, a researcher has proposed a theory that it could still be in lunar orbit. Planetary radar could be used to detect the spacecraft, which is larger than the Lunar Reconnaissance Orbiter and could be easily detectable. Although the likelihood of spotting Eagle optically seems unlikely, its recovery could provide a wealth of useful information.
