Thermophysical Model Development for Hera Mission to Simulate Non-Gravitational Acceleration on Binary Asteroid
Masanori Kanamaru, Tatsuaki Okada, Hiroki Senshu +4
The surface temperature of an asteroid is fundamental information for the design of an exploration mission and the interpretation of scientific observations. In addition, the therm…
The spatial distribution of impact craters on Ryugu
Naoyuki Hirata, Tomokatsu Morota, Yuichiro Cho +40
Asteroid 162173 Ryugu has numerous craters. The initial measurement of impact craters on Ryugu, by Sugita et al. (2019), is based on Hayabusa2 ONC images obtained during the first…
Rotational effect as the possible cause of the east-west asymmetric crater rims on Ryugu observed by LIDAR data
Naoyuki Hirata, Noriyuki Namiki, Fumi Yoshida +13
Asteroid 162173 Ryugu is a rubble-pile asteroid, whose top-shape is compatible with models of deformation by spin up. Rims of major craters on Ryugu have an east-west asymmetric pr…
The Western Bulge of 162173 Ryugu Formed as a Result of a Rotationally Driven Deformation Process
Masatoshi Hirabayashi, Eri Tatsumi, Hideaki Miyamoto +26
162173 Ryugu, the target of Hayabusa2, has a round shape with an equatorial ridge, which is known as a spinning top-shape. A strong centrifugal force is a likely contributor to Ryu…
Cratering Experiments on the Self Armoring of Coarse-Grained Granular Targets
Carsten Güttler, Naru Hirata, Akiko M. Nakamura
Recently published crater statistics on the small asteroids 25143 Itokawa and 433 Eros show a significant depletion of craters below approx. 100 m in diameter. Possible mechanisms…
The Hayabusa Spacecraft Asteroid Multi-Band Imaging Camera: AMICA
Masateru Ishiguro, Ryosuke Nakamura, David J. Tholen +12
The Hayabusa Spacecraft Asteroid Multiband Imaging Camera (AMICA) has acquired more than 1400 multispectral and high-resolution images of its target asteroid, 25143 Itokawa, since…
