In the past few years, several major space missions have been completed (eg, Deep Impact,
LCROSS, Chandrayaan-1, Stardust, Hayabusa), and a number of spacecraft are currently …

Mercury's regolith, derived from the crustal bedrock, has been altered by a set of space
weathering processes. Before we can interpret crustal composition, it is necessary to …

We present an experimental study on ion irradiation of carbonaceous chondrites, simulating
solar wind irradiation on primitive asteroids, to better constrain the space weathering …

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 …

Lunar-style space weathering is well understood, but cannot be extended to asteroids in
general. The two best studied Asteroids (433 Eros and 243 Ida) exhibit quite different space …

Aims. The goal of this study is to simulate space weathering processes on primitive bodies.
We use ion implantation as a simulation of solar wind irradiation, which has been suggested …

Space weathering (SW) processes affect airless bodies in the solar system. These
processes include irradiation by solar ion populations (solar wind, flares, solar-energetic …

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 …

Solar wind ion irradiation continuously modifies the optical properties of unprotected
surfaces of airless bodies in the Solar System. This alteration induces significant biases in …

Context. Space weathering is a process that changes the surface of airless planetary bodies.
Prime space weathering agents are solar wind irradiation and micrometeoroid …
