Mirror cast for Mexican 6.5-meter infrared telescope With the casting today (Wed., Aug. 26) of a 6.5-meter mirror in Arizona, Mexican and American astronomers have taken the first step toward creation of a major new telescope that will survey infrared objects in the northern sky with unprecedented sensitivity. The new mirror is destined for the planned San Pedro Mártir Telescope, which would be built at the San Pedro Mártir Observatory in Baja California, Mexico. When completed in 2017, the telescope will begin the Synoptic All-Sky Infrared Imaging Survey (SASIR) to look for faint infrared sources - ranging from dim, nearby stars to distant quasars - and flashes of infrared light from supernovas and other transient sources.
