Two screws from the Surveyor 3 spacecraft recovered during the Apollo 12 mission have been investigated for micrometeorite impact features.

The three largest Skylab IV Command Module windows that were exposed for 84 days to space were optically scanned for impact features as small as 30 µm in diameter. Some 289 features were recorded from the 35x scan for later ...

Probability arguments would indicate that about 70% of the meteorite influx would land in the oceans, yet there is no obvious and compelling evidence for such events, especially for craters that would, on land, be of the ...

At sufficiently high impact velocities, plasma clouds are generated in the early stages of hypervelocity impacts.
