Spectrally blue hydrated parent body of asteroid (162173) Ryugu

Nature Communications, 2021
Both poles of asteroid Ryugu, the target of space mission Hayabusa2, preserve the least processed material by space weathering. Here, the authors show detection of 700 nm absorption band in the polar spectra of Ryugu, that allows to constrain the ...

Alignment determination of the Hayabusa2 laser altimeter (LIDAR)

Earth, Planets and Space, 2021
In this study, we determined the alignment of the laser altimeter aboard Hayabusa2 with respect to the spacecraft using in-flight data. Since the laser altimeter data were used to estimate the trajectory of the Hayabusa2 spacecraft, the pointing ...
