Apollo 16 Orion

Apollo 16’s Lunar Module Orion landed in the Descartes Highlands, the only Apollo mission to explore the central highland region. Astronauts John Young and Charles Duke conducted three EVAs with the Lunar Roving Vehicle, collecting a record 95.71 kg of samples. Their findings overturned the prevailing theory that the Descartes region was volcanic in origin — instead, it was composed of impact breccias. Duke also operated the first astronomical telescope on the Moon, a far-UV camera/spectrograph.
