Remembering Challenger 20 Years Later

Twenty years ago, space shuttle Challenger blew apart into jets of fire and plumes of smoke, a terrifying sight witnessed by the families of the seven astronauts and by those who came to watch the historic launch of the first teacher in space.
The disaster shattered NASA's spit-shined image and the belief that spaceflight could become as routine as airplane travel. The investigation into the accident's cause revealed a space agency more concerned with schedules and public relations than safety and sound decision-making.
Seventeen years later, seven more astronauts were lost on the shuttle Columbia, leading many to conclude NASA had not learned the lessons of Challenger. But after last summer's successful return to flight under the highest level of engineering scrutiny ever, many space watchers are more hopeful.
"Don't we all learn as we go?" said Grace Corrigan, who lost her daughter, teacher Christa McAuliffe, in the Challenger accident. "Everybody learns from their mistakes." Joining McAuliffe on the doomed Jan. 28, 1986 Challenger flight were commander Dick Scobee, pilot Mike Smith and astronauts Ellison Onizuka, Judy Resnik, Ron McNair and Greg Jarvis.
"It was one of those defining moments in your life that you will always remember," said U.S. Sen. Bill Nelson, D-Fla., who had flown on the shuttle mission preceding Challenger. "Because in 1986, the space shuttle was the symbol of technological prowess of the United States and all the sudden it's destroyed in front of everybody's eyes."
The two shuttle disasters, as well as the deaths of the Apollo 1 crew during a 1967 launch pad test, taught the space agency how to improve the herculean task of launching humans into space, NASA administrator Michael Griffin said recently. On Thursday, NASA workers paused for their annual Day of Remembrance in honor of those lost in all three accidents. On Saturday, a ceremony remembering the Challenger accident is planned at Kennedy Space Center.
Challenger was brought down just after liftoff by a poorly designed seal in the shuttle's solid rocket booster, which has since been redesigned and has performed without problems. It will be used on the next-generation vehicle with plans to return astronauts to the moon and later to Mars.
