Geminid meteors seen striking the Moon - space - 05 January 2007 - New Scientist Space

"Two small NASA telescopes with their lenses trained on the Moon spied
five, and possibly six, Geminid meteoroids striking the lunar surface
early on the morning of 14 December. The observations will help NASA
design safe shelters for its future Moon base.

On Earth, most meteors burn up as they crash through the atmosphere.
The Moon's atmosphere is negligible, however, so the largest of the
space rocks crash into its surface with the force of 8-tonne bombs.

"We hope to learn how often big rocks crash into the Moon since we're
sending astronauts back," says Bill Cooke, of the Meteoroid Environment
Office at NASA's Marshall Space Flight Center in Huntsville, Alabama,
US."
