Shuttle Atlantis races to space station

Space shuttle Atlantis is speeding after the International Space Station for a Sunday morning hook-up.

Nasa said the docking would not be delayed, even if the space station needed to dodge space junk. Flight controllers have been monitoring an unidentified piece of debris for at least a day. A move by the station, if required, would happen tonight.

The shuttle and its six astronauts will spend a week at the station, installing fresh batteries and a new Russian compartment.

Atlantis rocketed into orbit on Friday from Cape Canaveral, Florida, for the last time. It's the 32nd flight for Atlantis in a quarter of a century.

Two more shuttle flights remain. Nasa is ending the program so it can focus on presidential-ordered trips to asteroids and Mars.
