Atlantis ready to return to Earth

Astronauts aboard space shuttle Atlantis are preparing to return to Earth after an ambitious and risky mission to re-fit the Hubble telescope.
There are two chances to land on Friday: one at 1500 BST (1000 EDT) and a second at 1639 BST (1139 EDT).

On a marathon spacewalk Sunday, two astronauts overcame repeated obstacles to make the second of two historic repairs to the Hubble Space Telescope.
One bolt that had to be extracted proved so stubborn that astronaut Michael Massimino resorted to brute force to rip it out of the telescope.
