The U.S. shuttle Discovery has blasted off on its final mission before the spacecraft is retired after more than 25 years in service.
The shuttle launched February 24 from the Kennedy Space Center in Florida to start an 11-day mission to deliver a new module and a humanoid robot to the International Space Station.
NASA says Discovery, which blasted into space for the first time in 1984, is the most-flown spacecraft in history.
After Discovery returns to earth on March 7 it will become the first of the three remaining U.S. space shuttles to be retired, as NASA winds down the space shuttle program after 30 years.
