It's official: In 15 months, NASA will send a space shuttle to service the aging Hubble Space Telescope. Plans to return to Hubble were put on hold 4 years ago after Columbia disintegrated. NASA chief Michael Griffin pledged last year to reverse his predecessor's decision to let Hubble die, but the space agency waited until Atlantis lifted off from its Florida launch pad last week to put the 10 September 2008 servicing flight on the busy shuttle schedule. If the maintenance mission—its fifth—is successful, Hubble will sport two new instruments. The Cosmic Origins Spectrograph and Wide Field Camera 3 will, respectively, measure the structure and composition of matter and examine the universe in multiple wavelengths. By replacing gyroscopes and filling the fuel tank, the mission is also expected to extend the life of the telescope, first launched in 1990, to 2013. That's also when NASA intends to launch its James Webb Space Telescope, Hubble's follow-on.
