The space shuttle Atlantis stands ready for its final mission.
NASA is readying the shuttle Atlantis for launch Friday on the iconic program's 135th and final flight, bringing the curtain down on one of the nation's greatest technological triumphs after more than three decades at the apex of manned spaceflight.
Carrying a reduced crew of four to minimize potential post-launch rescue complications, Atlantis is scheduled for liftoff at 11:26 a.m. EDT, roughly the moment Earth's rotation carries launch complex 39A into the plane of the International Space Station's orbit.
NASA said in a briefing this morning that, despite some iffy weather in the forecast, it still expects to have an on-time launch.
Strapped in on Atlantis' upper flight deck will be commander Christopher Ferguson, pilot Douglas Hurley, flight engineer Rex Walheim, and space station veteran Sandra Magnus. All four are spaceflight veterans and all four clearly recognize the historic nature of their voyage.
"That is the most graceful, beautiful vehicle we've had to fly in space, ever, and it's going to be a long time until you see a vehicle roll out to the pad that looks as beautiful as that," Walheim said during Atlantis' move to the launch pad May 31. "How can you beat that? An airplane on the side of a rocket. It's absolutely stunning.
Huge crowds are expected as space aficionados, tourists and area residents turn out for a final chance to see the world's most powerful manned spaceship blast off for the last time. Brevard County officials expect between a half million and 750,000 spectators to jam area roads and beaches.
