Space weathering processes that operate in the lunar regolith modify the surfaces of lunar
soil grains. Transmission electron microscope analysis of the lunar soil grains from the fine …

We have studied the effects of 4 keV He+ ion irradiation on olivine while measuring, in situ,
changes in the near‐infrared (NIR) reflectance and in the chemical composition of the …

We performed H+ and He+ irradiation experiments on slabs of the Murchison CM2 meteorite
to simulate solar wind irradiation of carbonaceous asteroids. Two separate 6 mm× 6 mm …

Little is known about carbonaceous asteroids weathering in space as previous studies have
struggled to define a general spectral trend among dark surfaces. Here we present …

To shed light on the mechanism of formation of nanophase iron particles (npFe) in space‐
weathered materials from airless bodies, we analyzed exsolved and unexsolved space …

Analytical transmission electron microscope (TEM) observations reveal that ilmenite grains
sampled from the sub‐10 μm size fraction of Apollo 11 (10084) and Apollo 16 (61221 …

We present results from a set of low and high flux 1 keV/amu H+ and He+ irradiation
experiments performed on slabs of the Murchison CM2 carbonaceous chondrite. The low …

Despite their micrometer-scale dimensions and nanogram masses, chondritic porous
interplanetary dust particles (CP IDPs) are an important class of extraterrestrial material …

During recent years, a growing body of evidence, both astrophysical observations of young
stellar objects and cosmochemical observations made on meteorites, has strengthened the …

Solar-wind erosion of rocks on the lunar surface and the implanting of solar-wind particles in
minerals of lunar regolith are principally important processes of space weathering. The latter …
