Hubble Mission Update

The crew of the Space Shuttle Atlantis today continue their mission to repair and upgrade the Hubble Space telescope. Over the past week or so, the team have completed four space walks (or EVA's) and during today's final EVA they plan to replace the telescope batteries, replace external shielding and install a new pointing sensor. The crew have already replaced the lens of the telescope. The mission has been a resounding success so far and the crew will return to Earth on Friday, when the shuttle touches down in the Kennedy Space Centre in Florida.
