On-going space missions NASA's OSIRIS-REx and JAXA's Hayabusa2 are gathering more and more information on asteroid regolith. In order to better understand how regolith respond to processes occurring in space (particularly micro-meteoroid impacts and thermal cracking), we have developed asteroid analog materials. In the present paper we focus on...

The two on-going sample return space missions, Hayabusa2 and OSIRIS-REx are going to return to Earth asteroid regolith from the carbonaceous near-Earth asteroids Ryugu and Bennu. The two main processes that lead to regolith production are the micrometeorite bombardment and the thermal cracking. Here we report the production of a weak simulant...

Two on-going sample return space missions, Hayabusa2 and OSIRIS-REx are orbiting and characterising two near-Earth asteroids, (162173) Ryugu and (101955) Bennu respectively. Initial ground-based observations and preliminary mission data indicate that the composition of these small objects is similar to the CM or CI meteorites [1-4]. However,...
