The Japanese Hayabusa2 mission (JAXA) has brought back samples from the carbonaceous primitive asteroid Ryugu. Thanks to the analyses of these samples by an international group led by Prof. Tomoki Nakamura (Tohoku Univ., Japan), it is possible to propose a scenario retracing the history of Ryugu, including its formation after the fragmentation of its parent asteroid.

Using the orbital imaging spectroscopy instruments OMEGA (Mars Express) and CRISM (MRO), the Solar System team has released the first global and high resolution map of hydrated minerals on Mars. These minerals hold the distinction of having been formed through interaction between the ancient Martian crust and liquid water, while many of them still contain some amount of water trapped within their structure. Such hydrated minerals are excellent tracers of past water-bearing environments and are a primary target of exobiology missions to Mars.
