Space Shuttle Atlantis is preparing to land for the final time, ending NASA's 30-year shuttle programme.
The orbiter is scheduled to land just before 11 AM BST at the Kennedy Space Center in Florida
After completing its 13-day mission to the International Space Station the shuttle will be retired.
NASA has resisted calls to schedule the landing for later in the day to provide a better view for the thousands of spectators expected to try and witness the final stages of the descent.
Follow the landing live, via NASA TV and Ustream.
