NASA's improbably acronmyed* "Origins, Spectral Interpretation, Resource Identification, Security – Regolith Explorer" OSIRIS-REx spacecraft has arrived at Florida's Kennedy Space Center ahead of a September launch on an asteroid-sampling mission.
OSIRIS-REx will travel to near-Earth asteroid Bennu, arriving in 2018, and spend two years mapping the approximately 500-510 metre diameter object before collecting a surface sample for return to Earth.
The OSIRIS-REx Thermal Emission Spectrometer OTES will collect "mineral and temperature information by collecting infrared from 5 to 50 microns spectral data"
OVIRS "OSIRIS-REx Visible and Infrared Spectrometer" will, meanwhile, measure visible and infrared light from Bennu.
Finally, the Regolith X-ray Imaging Spectrometer REXIS - developed in collaboration with MIT and Harvard University - will sniff "which elements are present, and how abundant they are, on the surface of Bennu".
The space agency believes it can hoover up 2kg of Bennu - or at least 60g at worst - for return to Earth aboard the Sample Return Capsule SRC - "an aeroshell design container with a heatshield and parachutes".
