Final Liftoff

NASA:

"Rising on twin columns of fire and creating rolling clouds of smoke and steam, space shuttle Discovery lifts off Launch Pad 39A at NASA's Kennedy Space Center in Florida on a picturesque, warm, late February afternoon. Launch of the STS-133 mission was at 4:53 p.m. EST on Feb. 24. 2011."

135 missions sent. A look back at the program.
