Yay. Japan's Hayabusa2 has touchdown on asteroid Ryugu again
and possibly collected more samples.
Japan's Hayabusa2 spacecraft has touched down on Ryugu for a second time, bagging samples which hopefully contain material from the subsurface of the asteroid.
The first touchdown in February saw Hayabusa2 successfully collect samples from the primitive C-type asteroid Ryugu, achieving one of the main science goals of the mission.
JAXA and ISAS however decided to proceed with a second touchdown in order to boost sample volume, perform an unprecedented multi-sampling from a planetary body and, crucially, collect subsurface material excavated by the SCI experiment. In doing so the team will aim to answer questions regarding the very low reflectance of Ryugu, give insight into the regional heterogeneity of celestial bodies and, through comparison, assess the impact of solar wind on the surface.
