After more than a decade of fascinating discoveries, The Hubble Space Telescope will soon be given the new beginning that it deserves. On Tuesday, 31 October 2006, NASA has decided to approve a Space Shuttle mission to repair and upgrade the observatory, despite new Shuttle safety rules formulated after the Columbia disaster that would normally rule out such a rescue mission.

By combining numerous Hubble observations taken over a 3-year period with ground based observations, a team of astronomers led by G. Fritz Benedict and Barbara E. McArthur has deduced the inclination of the nearest exoplanet's orbit around its parent star Epsilon Eridani and found it to be aligned with the star's debris disk.

Hubble's workhorse, the Advanced Camera for Surveys (ACS), resumed science operations on 1 October 2006 with one of its three channels, the Wide Field Channel (WFC), brought back into service. Historically, this channel has accounted for 70-80% of all observations obtained with the ACS. Observations with the WFC form an integral part of the HST science observing plan for next week.
