Lancaster,S. Oliver,C. Oquest,D. Crowley,C. Morgan,C. Castle,Raúl Domínguez,M. Sullivan +55 more
TL;DR: The OSIRIS-REx Camera Suite (OCAMS) as discussed by the authors consists of three cameras, the MapCam, the SamCam and the PolyCam, which are used to collect color images of the surface of the asteroid Bennu.

TL;DR: The requirements-driven OSIRIS-REx Camera Suite (OCAMS) as discussed by the authors acquires images essential to collecting a sample from the surface of Bennu, which enables an accurate digital terrain model of the shape of the asteroid and identify any surface hazards.

OSIRIS-REx OCAMS detector assembly characterization
J. Hancock,B. Crowther,M. Whiteley,R. Burt,Mike Watson,J. V. Nelson,C. Fellows,Bashar Rizk,E. Kinney-Spano,Mark E. Perry,M. Hunten +10 more
TL;DR: The Space Dynamics Laboratory at Utah State University is providing the CCD-based detector assemblies for OCAMS to the Lunar Planetary Lab at the University of Arizona, and a prototype system was built to verify the functionality of the detector assembly design and to characterize the detector system performance at the intended operating temperatures.
Journal ArticleDOI
Performing tomographic reconstructions from a satellite looking toward Earth. Part 2: analysis of image quality.
TL;DR: In this paper , a simplified model of short-wave infrared emissions in the atmosphere is given, and tomographic reconstructions from a space platform are performed using maximum likelihood expectation maximization.
