Journal ArticleDOI
The Rubble-Pile Asteroid Itokawa as Observed by Hayabusa
Akira Fujiwara,Jun'ichiro Kawaguchi,D. K. Yeomans,Masanao Abe,Tadashi Mukai,Tatsuaki Okada,Jun Saito,Hajime Yano,Makoto Yoshikawa,Daniel J. Scheeres,Olivier S. Barnouin-Jha,A. F. Cheng,Hirohide Demura,R. W. Gaskell,Naru Hirata,H. Ikeda,T. Kominato,Hirdy Miyamoto,Akiko M. Nakamura,Ryosuke Nakamura,Sho Sasaki,K. Uesugi +21 more
TL;DR: During the interval from September through early December 2005, the Hayabusa spacecraft was in close proximity to near-Earth asteroid Itokawa, and a variety of data were taken on its shape, mass, and surface topography as well as its mineralogic and elemental abundances.
Journal ArticleDOI
Identification of hydrated silicate minerals on Mars using MRO‐CRISM: Geologic context near Nili Fossae and implications for aqueous alteration
Bethany L. Ehlmann,John F. Mustard,Gregg A. Swayze,Roger N. Clark,Janice L. Bishop,Janice L. Bishop,François Poulet,David J. Des Marais,Leah H. Roach,Ralph E. Milliken,James J. Wray,Olivier S. Barnouin-Jha,Scott L. Murchie +12 more
TL;DR: In this article, the authors used the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard the Mars Reconnaissance Orbiter (MRO) to detect alteration minerals in the Noachian terrain west of the Isidis basin.
Journal ArticleDOI
Touchdown of the Hayabusa spacecraft at the Muses Sea on Itokawa.
Hajime Yano,Takashi Kubota,Hideaki Miyamoto,Tatsuaki Okada,Daniel J. Scheeres,Y. Takagi,Kazuya Yoshida,Masanao Abe,Shinsuke Abe,Olivier S. Barnouin-Jha,Akira Fujiwara,Sunao Hasegawa,Tatsuaki Hashimoto,Masateru Ishiguro,M. Kato,Jun'ichiro Kawaguchi,T. Mukai,Jun Saito,Sho Sasaki,Makoto Yoshikawa +19 more
TL;DR: Initial findings about geological features, surface condition, regolith grain size, compositional variation, and constraints on the physical properties of this site are reported by using both scientific and housekeeping data during the descent sequence of the first touchdown.
Journal ArticleDOI
Regolith Migration and Sorting on Asteroid Itokawa
Hideaki Miyamoto,Hajime Yano,Daniel J. Scheeres,Shinsuke Abe,Olivier S. Barnouin-Jha,A. F. Cheng,Hirohide Demura,Robert Gaskell,Naru Hirata,Masateru Ishiguro,Tatsuhiro Michikami,Akiko M. Nakamura,Ryosuke Nakamura,Jun Saito,Sho Sasaki +14 more
TL;DR: High-resolution images of the surface of asteroid Itokawa from the Hayabusa mission reveal it to be covered with unconsolidated millimeter-sized and larger gravels, indicating that it has experienced considerable vibrations, which have triggered global-scale granular processes in its dry, vacuum, microgravity environment.
Journal ArticleDOI
Mass and Local Topography Measurements of Itokawa by Hayabusa
Shinsuke Abe,Tadashi Mukai,Naru Hirata,Naru Hirata,Olivier S. Barnouin-Jha,Andrew F. Cheng,Hirohide Demura,R. W. Gaskell,Tatsuaki Hashimoto,K. Hiraoka,T. Honda,Takashi Kubota,Masatoshi Matsuoka,Takahide Mizuno,Ryosuke Nakamura,Daniel J. Scheeres,Makoto Yoshikawa +16 more
TL;DR: Combined with surface observations, these data indicate that Itokawa is the first subkilometer-sized small asteroid showing a rubble-pile body rather than a solid monolithic asteroid.
