Journal ArticleDOI
The operational environment and rotational acceleration of asteroid (101955) Bennu from OSIRIS-REx observations
Carl Hergenrother,C. K. Maleszewski,Michael C. Nolan,Jian-Yang Li,C. Drouet d'Aubigny,F. Shelly,Ellen S. Howell,Theodore Kareta,Matthew R.M. Izawa,M. A. Barucci,E. B. Bierhaus,Humberto Campins,Steven R. Chesley,Beth E. Clark,Eric Christensen,Daniella DellaGiustina,Sonia Fornasier,Dathon Golish,Christine Hartzell,Bashar Rizk,Daniel J. Scheeres,P. H. Smith,Xiao-Duan Zou,Dante S. Lauretta +23 more
TL;DR: The authors show the operational environment of asteroid Bennu, validate its photometric phase function and demonstrate the accelerating rotational rate due to YORP effect using the data acquired during the approach phase of OSIRIS-REx mission.
Journal ArticleDOI

Michael F. A'Hearn,M. J. S. Belton,W. A. Delamere,Jochen Kissel,Kenneth P. Klaasen,Lucy A. McFadden,Karen J. Meech,H. J. Melosh,Peter H. Schultz,Jessica M. Sunshine,Peter C. Thomas,J. Veverka,Donald K. Yeomans,M. W. Baca,I. Busko,C. J. Crockett,Steven M. Collins,Mark Desnoyer,C. A. Eberhardy,Carolyn M. Ernst,Tony L. Farnham,Lori M. Feaga,Olivier Groussin,Donald Hampton,Sergei I. Ipatov,Jian-Yang Li,Don J. Lindler,Carey M. Lisse,Carey M. Lisse,N. Mastrodemos,William M. Owen,James E. Richardson,James E. Richardson,Dennis D. Wellnitz,R. L. White +34 more
TL;DR: A large increase in organic material occurred during and after the event, with smaller changes in carbon dioxide relative to water, and a thermal map indicates a surface in equilibrium with sunlight.
Journal ArticleDOI
EPOXI at Comet Hartley 2
Michael F. A'Hearn,M. J. S. Belton,W. Alan Delamere,Lori M. Feaga,Donald Hampton,Jochen Kissel,Kenneth P. Klaasen,Lucy A. McFadden,Lucy A. McFadden,Karen J. Meech,H. Jay Melosh,H. Jay Melosh,Peter H. Schultz,Jessica M. Sunshine,Peter C. Thomas,Joseph Veverka,Dennis D. Wellnitz,Donald K. Yeomans,Sebastien Besse,Dennis Bodewits,Timothy J. Bowling,Brian Carcich,Steven M. Collins,Tony L. Farnham,Olivier Groussin,Brendan Hermalyn,Michael S. P. Kelley,Jian-Yang Li,Don J. Lindler,Carey M. Lisse,S. McLaughlin,Frederic Merlin,Frederic Merlin,Silvia Protopapa,James E. Richardson,J. L. Williams +35 more
TL;DR: In situ observations show that comet Hartley 2 is an unusually hyperactive comet, and this nucleus is outgassing primarily because of CO2, which drags chunks of ice out of the nucleus.
Journal ArticleDOI
Exposed water ice deposits on the surface of comet 9P/Tempel 1.
Jessica M. Sunshine,Michael F. A'Hearn,Olivier Groussin,Jian-Yang Li,M. J. S. Belton,W. A. Delamere,Jochen Kissel,Kenneth P. Klaasen,Lucy A. McFadden,Karen J. Meech,H. J. Melosh,Peter H. Schultz,Peter C. Thomas,J. Veverka,Donald K. Yeomans,I. Busko,Mark Desnoyer,Tony L. Farnham,Lori M. Feaga,Donald Hampton,Don J. Lindler,Carey M. Lisse,Dennis D. Wellnitz +22 more
TL;DR: The direct detection of solid water ice deposits exposed on the surface of comet 9P/Tempel 1, as observed by the Deep Impact mission, suggests that the surface deposits are loose aggregates.
Journal ArticleDOI
Elemental mapping by Dawn reveals exogenic H in Vesta's regolith.
Thomas H. Prettyman,David W. Mittlefehldt,Naoyuki Yamashita,David J. Lawrence,Andrew W. Beck,W. C. Feldman,Timothy J. McCoy,Harry Y. McSween,Michael J. Toplis,Timothy N. Titus,Pasquale Tricarico,Robert C. Reedy,John S. Hendricks,Olivier Forni,L. Le Corre,Jian-Yang Li,H. Mizzon,Vishnu Reddy,Carol A. Raymond,Christopher T. Russell +19 more
TL;DR: Analysis of data from the Dawn spacecraft implies that asteroid Vesta is rich in volatiles, and models of Vesta’s evolution based on studies of howardite, eucrite, and diogenite meteorites are tested, finding that global Fe/O and Fe/Si ratios are consistent with HED compositions.
