The JAXA and NASA space missions Hayabusa 2 and Osiris-Rex have the ambitious objective to orbit around two primitive carbonaceous Near Earth Asteroids (162173 Ryugu and 101955 Bennu) to understand the origin and evolution of the Solar System. The two missions will collect samples of the two bodies and return back them to the Earth for further and more accurate analysis in laboratory. At the time of the EGU Assembly, Hayabusa 2 will likely have already published their first results about Ryugu and Osiris-Rex will have started to survey of Bennu. This session is open to all the scientists directly involved in the two missions to show the first results obtained so far, and to discuss possible links between the two objects. Nevertheless, we invite all other scientists to present their scientific discussions, modelling, laboratory simulations about these two primitive NEA’s. We believe that this session is rare opportunity to show the hot scientific results of Hayabusa 2 and Osiris-Rex involving a scientific audience much wider than the specific planetary science community
