The Ranger 6 Robotic Spacecraft | NASA Headquarters – GReatest Images of NASA (NASA-HQ-GRIN) – Great Images in NASA Description
On February 2, 1964, the Ranger 6 probe was deliberately crash-landed on the surface of the Moon to obtain up-close, high-resolution photos of the lunar surface during the final minutes before impact. The probe made impact in the Sea of Tranquility, a lunar mare1 located in the Moon’s Tranquillitatis Basin. The probe carried 6 television cameras, each containing their own power supply and transmitter to ensure the highest probability of success. However, due to a failure in the probe’s camera system, no images could be returned to Earth.
1 A lunar mare (plural “maria”) is a large, dark, basaltic plain on Earth’s Moon, formed by volcanic activity. They were called maria (Latin for “seas”) by early astronomers who mistook them for bodies of water on the lunar surface.
