[Press Release] Pebbles flying over Ryugu and returned grains
We combined the results of multi-scale observations of Ryugu surface particles by CAM-H during the spacecraft touchdowns, the observations made by the MINERVA-II1 hopping rovers at multiple locations across the asteroid, and the return samples in the clean chamber. We found that the return samples well represent Ryugu surface particles and that there are characteristic flat and elongated particles on the asteroid. In addition, CAM-H images showed that the sampler system correctly operated to collect and return 5 grams of samples. For more information, access this page.
