We detected more than 1000 crater structures in the Western Egyptian Desert, distributed over 40000 km2, among which 62 were studied on the field. Two hypotheses are proposed for their origin: hydrothermal vent complexes or impact craters generated by a rubble-pile asteroid.

Consert for Asteroid is a radar to instrument the Mascot lander, which is proposed in the frame of future Near Earth Asteroid missions. This low frequency radar is a unique opportunity to sound the internal structure of the target. Its objective is to achieve the tomography both in transmission and in reflexion of the asteroid in order to...

Our knowledge of the internal structure of asteroids is, so far, indirect – relying entirely on inferences from remote sensing observations of the surface, and theoretical modeling of formation and evolution. What are the bulk properties of the regolith and deep interior? And what are the physical processes that shape asteroid internal...
