Canada will build a key component of the gigantic James Webb Space Telescope (JWST) to be launched by NASA in August 2011. The Canadian Space Agency (CSA) recently awarded a $5-million contract to Ottawa-based EMS Technologies' Space and Technology Group for the design of the fine guidance sensor, in partnership with COM DEV of Cambridge, Ontario. Northrup Grumman Space Technologies of Los Angeles, California, will build the JWST under NASA supervision at an estimated cost of US$1.5 billion.
