These tracks are evidence of a recent quake because they should be erased relatively quickly, in geologic time scales, by the constant rain of micrometeoroid
impacts on the moon.

Thales Alenia Space produced and tested the critical pressure shell for Bishop, as well as various secondary structures, including the Micrometeoroid
and Orbital Debris (MMOD) shields with multilayer insulation (MLI) panels, the power and video grapple fixture support structure and other structural components.
Some thought it occurred due to micrometeoroid
impact or production marriage, while others indicated a deliberate effort to compromise the ship.
Recent studies have shown that the environmental conditions that are the most representative of space and that tend to degrade the properties of composite laminates involve vacuum, thermal cycling atomic oxygen (AO), and micrometeoroid
and Orbital Debris Integrated Threat Mitigation Techniques for the Space Shuttle Orbit er Assessment, IAC-08-A6.3.1 (2009)).
Material tends to redden gradually with exposure to the space environment for several reasons, two of which are radiation-spurred changes in molecular structure and the breakup of microscopic grains by micrometeoroid
"The Earth/moon system orbits the sun with an average speed of 67,000 miles per hour, and like bugs on a car windshield, the interplanetary micrometeoroid
materials smack into the 'upstream' side of the Earth and moon," Rick Elphic, a LADEE project scientist who didn't participate in the recent study, told Mashable.
The ring, called the Phoebe ring, is believed to contain dust and ice particles ejected from Saturns outer moon, Phoebe, after micrometeoroid
and other impacts, Discovery News reported.
GOES-13 had experienced a major anomaly, possibly because of a collision with a micrometeoroid
The reason for using the multifilament design is to make the tethers more resistant to micrometeoroid
Previous studies suggested that the regolith of asteroids one kilometer wide and smaller was made from material falling to the surface after impacts and from boulders that were pulverized by micrometeoroid
