Optical maturation of asteroid surfaces

Icarus, 2013
Abstract Analysis of laboratory experiments simulating space weathering optical effects on atmosphereless planetary bodies reveals that the time needed to alter the spectrum of an ordinary chondrite meteorite to resemble the overall spectral shape and slope of an S-type asteroid is about ∼10 5  yr.

SPACE WEATHERING OF ASTEROID SURFACES

Annual Review of Earth and Planetary Sciences, 2004
▪ Abstract  Visible and near-infrared spectra of reflected sunlight from asteroid surfaces exhibit features that hold the promise for identifying surface mineralogy. However, the very surfaces that are observed by remote-sensing are also subject to impingement by micrometeoroids and solar wind particles, which are believed to play the dominant role in ...

Asteroidal agglutinate formation and implications for asteroidal surfaces

Icarus, 1981
The possible role of spallation on the free surfaces of target bodies in asteroid surface evolution in the presence of colliding bodies is considered. The ease of impact melt formation is discussed based on the results of shock recovery experiments, and a difference between collisions with dense, nonporous targets and with porous, particulate powders ...
