No Trojan asteroids found, but OSIRIS-REx successfully prepares on-board cameras By Tom Beal Arizona Daily Star Mar 24, 2017 Updated Mar 24, 2017
The OSIRIS-REx spacecraft didn’t find any Earth Trojans caught up in Earth’s orbit during its February search for asteroids, but its cameras worked better than expected in a critical test of their capability.
University of Arizona planetary scientist Dante Lauretta, principal investigator for the NASA mission to sample a primordial asteroid named Bennu, said the spacecraft’s MapCam imager had a “much higher sensitivity” than it was designed to have.
