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
Rain, winds and haze during the Huygens probe's descent to Titan's surface
Martin G. Tomasko,Brent A. Archinal,Tammy L. Becker,Bruno Bézard,M. Bushroe,M. Combes,D. Cook,Athena Coustenis,C. de Bergh,L. E. Dafoe,Lyn R. Doose,Sylvain Douté,A. Eibl,S. Engel,Fritz Gliem,B.

Soderblom,Nicolas Thomas,Robert West +40 more
TL;DR: Spectra and high-resolution images obtained by the Huygens Probe Descent Imager/Spectral Radiometer instrument in Titan's atmosphere reveal the traces of once flowing liquid, and like Earth, the brighter highland regions show complex systems draining into flat, dark lowlands.
Journal ArticleDOI

TL;DR: The OSIRIS-REx spacecraft departed for near-Earth asteroid (101955) Bennu via an United Launch Alliance Atlas V 411 evolved expendable launch vehicle at 7:05 p.m. EDT on September 8, 2016, on a seven-year journey to return samples from Bennu as discussed by the authors.
Journal ArticleDOI

Izawa,Hannah Kaplan,Michael C. Nolan,Bashar Rizk,H. L. Roper,Daniel J. Scheeres,P. H. Smith,Kevin J. Walsh,C. W. V. Wolner,Osiris-Rex Team +29 more
TL;DR: Early OSIRIS-REx observations of Bennu are considered to understand how the asteroid’s properties compare to pre-encounter expectations and to assess the prospects for sample return.
