NASA announced today that it has awarded an $825 million contract to aerospace firm TRW to build the replacement for the Hubble Space Telescope: The James Webb Space Telescope. Named for NASA's second administrator, this new observatory will launch in 2010 and operate 1.5 million km away from the Earth (Hubble is in low-Earth orbit). If all goes as planned, the observatory's 6 metre mirror will offer a tremendous leap in resolution over Hubble.
