The Near Earth Object Surveillance Satellite (NEOSSat) is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope similar to that on the MOST spacecraft, 3-axis stabilized with pointing stability of ~2 arcseconds in a ~100 second exposure. It will search for interior-to-Earth-orbit (IEO) asteroids including those sometimes called Apohele asteroids at between 45 and 55 degree solar elongation and +40 to -40 degrees ecliptic latitude.
