USA Today: The Advanced Camera for Surveys instrument on the Hubble Space Telescope has failed and can’t be fully repaired, NASA officials said Monday. The camera was installed on the HST in 2002 and is scheduled to be replaced in the 2008 service mission."Obviously we’re very disappointed,” said Hubble program manager Preston Burch. The lost instrument “was the newest camera, the highest-tech instrument and ⦠the most heavily in demand.” Two-thirds of the most recent proposals for use of Hubble required the advanced camera, he said.
