Resurfacing processes constrained by crater distribution on Ryugu
Naofumi Takaki, Yuichiro Cho, Tomokatsu Morota +16
Understanding the geological modification processes on asteroids can provide information concerning their surface history. Images of small asteroids from spacecraft show a depletio…
Image registration for multi-band images taken by ONC-T onboard Hayabusa2
Toru Kouyama, Eri Tatsumi, Chikatoshi Honda +13
Hayabusa2, a Japanese sample-return mission to a C-type asteroid, arrived at its target 162173 Ryugu in June 2018. The optical navigation cameras (ONC-T, ONC-W1, ONC-W2) successful…
Spectroscopic study of Ceres' collisional family candidates
Fernando Tinaut-Ruano, Julia de Leon, Eri Tatsumi +3
Context: Despite the observed signs of large impacts on the surface of Ceres, there is no confirmed collisional family associated with this dwarf planet. After a dynamical and phot…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 1. Size Frequency Distribution and Morphology
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
The near-Earth asteroid (162173) Ryugu displays a Cb-type average spectrum and a very low average normal albedo of 0.04. Although the majority of boulders on Ryugu have reflectance…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 2. Spectral Properties
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
Many small boulders with reflectance values higher than 1.5 times the average reflectance have been found on the near-Earth asteroid 162173 Ryugu. Based on their visible wavelength…
Widely distributed exogenic materials of varying compositions and morphologies on asteroid (101955) Bennu
Eri Tatsumi, Marcel Popescu, Humberto Campins +8
Using the multi-band imager MapCam onboard the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, we identified 77 i…
