An Explosion on the Moon
12.23.2005

So you thought nothing ever happens on the moon?

December 23, 2005: NASA scientists have observed an explosion on the moon. The blast, equal in
energy to about 70 kg of TNT, occurred near the edge of Mare Imbrium (the Sea of Rains) on Nov. 7,
2005, when a 12-centimeter-wide meteoroid slammed into the ground traveling 27 km/s.

see caption"What a surprise," says Marshall Space Flight Center (MSFC) researcher Rob Suggs, who
recorded the impact's flash. He and colleague Wes Swift were testing a new telescope and video
camera they assembled to monitor the moon for meteor strikes. On their first night out, "we caught
one," says Suggs.
