Derivation of 1.064 μm normal albedos on the C-type asteroid Ryugu from laser pulse intensity measurement of the Hayabusa2 LIDAR
Earth, Planets and Space, 2022 Japanese asteroid explorer Hayabusa2 arrived at C-type asteroid 162,173 Ryugu in June 2018. The laser altimeter (LIDAR) onboard Hayabusa2 measured its own transmitted laser and returned pulse intensities from a Ryugu surface until November 2019.Ryuhei Yamada, Keiko Yamamoto, Shoko Oshigami, Hiroshi Araki, Hiroki Senshu, Hirotomo Noda, Noriyuki Namiki, Koji Matsumoto, Fumi Yoshida, Shinsuke Abe, Naru Hirata, Sho Sasaki, Takahide Mizuno +12 moredoaj +1 more sourceTrace-element analysis of mineral grains in Ryugu rock fragment sections by synchrotron-based confocal X-ray fluorescence
