The smallest astronomical satellite ever built  launched Feb. 25, 2013 as part of a mission to prove that even a very small telescope can push the boundaries of astronomy. The satellite was designed and assembled at the Space Flight Laboratory of the University of Toronto Institute for Aerospace Studies (UTIAS). It was launched from the Satish Dhawan Space Centre in Sriharikota, India, along with its twin, also designed in Canada, but assembled in Austria.
