Back to Hubble

Here's a piece of good news for astronomers. NASA Administrator Michael Griffin gave the go-ahead to day for a final visit by the space shuttle to service the Hubble Space Telescope. The crew of seven has been announced and includes three veterans of previous servicing missions. Among the other objectives, two new instruments---the Cosmic Origins Spectograph and Wide Field Camera 3---are to be installed. (COS replaces the now useless COSTAR. WFC3 will replace WFPC2 and provide upgraded capabilities.)
