Shoemaker (lunar crater)

Due to the lack of illumination (it is a crater of eternal darkness), the albedo of the interior floor surface remains unknown.

Deposition of Shoemaker's remains was criticized by indigenous peoples as a desecration of the venerated Moon.

Two 34 m antennae, located 20 km apart, received the echoes, and the results were used to generate a topographic map with 150 m resolution.

[2] On July 31, 1999, Lunar Prospector was deliberately crashed into the floor of this crater to determine if a plume of water vapor would be detected.

The apparent detection of water and the shallow rim of this crater made it a suitable target for this experiment.
