22 Feb 2017 | | Abstract: | In May of 2011, NASA selected the Origins, Spectral Interpretation, Resource
Identification, and Security-Regolith Explorer (OSIRIS-REx) asteroid sample
return mission as the third mission in the New Frontiers program. The other two
New Frontiers missions are New Horizons, which explored Pluto during a flyby in
July 2015 and is on its way for a flyby of Kuiper Belt object 2014 MU69 on Jan.
1, 2019, and Juno, an orbiting mission that is studying the origin, evolution,
and internal structure of Jupiter. The spacecraft departed for near-Earth
asteroid (101955) Bennu aboard 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. The spacecraft is on an
outbound-cruise trajectory that will result in a rendezvous with Bennu in
August 2018. The science instruments on the spacecraft will survey Bennu to
measure its physical, geological, and chemical properties, and the team will
use these data to select a site on the surface to collect at least 60 g of
asteroid regolith. The team will also analyze the remote-sensing data to
perform a detailed study of the sample site for context, assess Bennus resource
potential, refine estimates of its impact probability with Earth, and provide
ground-truth data for the extensive astronomical data set collected on this
asteroid. The spacecraft will leave Bennu in 2021 and return the sample to the
Utah Test and Training Range (UTTR) on September 24, 2023. | | Source: | arXiv, 1702.6981 | | Services: | Forum | Review | PDF | Favorites | |
