Space shuttle Discovery is set to launch Thursday from Cape Canaveral, Florida, for its final flight, ending nearly three decades of space travel.
The six-member crew will deliver a storage module, a science rig and spare parts to the international space station during its 11-day mission.
Originally scheduled for November, Discovery’s launch was delayed because of repairs to the external tank’s support beams.
NASA, which is winding down the shuttle program, announced the February 24 launch a few weeks ago. It will be Discovery’s 39th voyage.
