The micrometeorites would pound the surface and ultimately become incorporated into deeper layers of the moon. Since the earth is constantly being bombarded by micrometeorites, many of them smaller than a grain of sand, it is by no means unlikely that the source of the sodium layer is vaporized micro meteorites--the view generally held among scientists. For STS-116, the ICC was specially configured to carry a variety of payloads, ranging from Service Module Debris Panels that will protect that space station segment from micrometeorites in the future, to a Department of Defense payload set to eject three micro-satellites upon the shuttle's undocking from the ISS. |
