The Near Earth Object Surveillance Satellite (NEOSSat)[9] 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 is funded by the Canadian Space Agency and Defence Research and Development Canada,[1] and will search for interior-to-Earth-orbit (IEO) asteroids,[10][11] at between 45 and 55 degree solar elongation and +40 to -40 degrees ecliptic latitude.[3]

Launch [edit]

NEOSSat was originally scheduled for launch in 2010, but delays set it back until 2013.[12] Alongside another Canadian spacecraft, Sapphire (a military survellience satellite), and five other satellites, NEOSSat launched on February 25, 2013, from the Satish Dhawan Space Centre in Sriharikota, India, at 12:31 UTC aboard an Indian PSLV-C20 rocket.[13][14]
