TL;DR: The Nuclear Spectroscopic Telescope Array (NuSTAR) is a NASA Small Explorer mission that will carry the first focusing hard X-ray (5 - 80 keV) telescope to orbit as discussed by the authors.

TL;DR: The AST-201 and ASC as discussed by the authors are the most accurate second-generation star trackers for spacecraft attitude determination, which use large internal star catalogs, use many stars for each data frame, have higher accuracy, smoother and more robust operation, potentially lower cost and output attitudes which are referenced directly to inertial space without any further external data processing.

TL;DR: The NASA Mars Exploration Rover mission will launch two scientific spacecraft to Mars in 2003 as discussed by the authors, which will include a stereo pair of Panoramic cameras and a Microscopic Imager, and six additional cameras that will be used, exclusively, for engineering.

TL;DR: In this paper, the authors describe the NuSTAR instrument metrology system architecture and implementation, focusing on the systems engineering challenges associated with validating the instantaneous transformations between focal plane and celestial coordinates to within the required accuracy.

TL;DR: The field of attitude determination sensors is mature as discussed by the authors, and different sensor technologies have been known for decades, and existing product lines are available for all types of sensors. Table 1 shows existing attitude determination sensor technologies.
