Space shuttle Discovery blasts off from Florida
Discovery roared off the launch pad at 4:53 p.m. EST (2153 GMT), with a six-member crew.
NASA plans to retire its shuttle program this year after two other spaceships in the shuttle fleet, Endeavour and Atlantis, make their last flights in the coming months.
