I was at work in Robinson Gym at the University of Kansas. As usual, I had the radio turned to the University NPR station KANU. They were carrying the live feed of the shuttle launch.
When the explosion happened, I must have looked stricken, because people started to stop at my counter and ask what was wrong. All I could answer was, 'We just lost Challenger with all hands on board.'
From the History Channel
At 11:38 a.m. EST, on January 28, 1986, the space shuttle Challenger
lifts off from Cape Canaveral, Florida, and Christa McAuliffe is on her
way to becoming the first ordinary U.S. civilian to travel into space.
McAuliffe, a 37-year-old high school social studies teacher from New
Hampshire, won a competition that earned her a place among the seven-member crew of the Challenger. She underwent months of shuttle training but then, beginning January 23, was forced to wait six long days as the Challenger‘s
launch countdown was repeatedly delayed because of weather and
technical problems. Finally, on January 28, the shuttle lifted off.
seconds later, hundreds on the ground, including Christa’s family,
stared in disbelief as the shuttle broke up in a forking plume of smoke
and fire. Millions more watched the wrenching tragedy unfold on live
television. There were no survivors.
In 1976, the National Aeronautics and Space Administration (NASA) unveiled the world’s first reusable manned spacecraft, the Enterprise. Five years later, space flights of the shuttle began when Columbia
traveled into space on a 54-hour mission. Launched by two solid-rocket
boosters and an external tank, only the aircraft-like shuttle entered
into orbit around Earth. When the mission was completed, the shuttle
fired engines to reduce speed and, after descending through the
atmosphere, landed like a glider. Early shuttles took satellite
equipment into space and carried out various scientific experiments. The
Challenger disaster was the first major shuttle accident.
In the aftermath of the disaster, President Ronald Reagan appointed a special commission to determine what went wrong with Challenger
and to develop future corrective measures. The presidential commission
was headed by former secretary of state William Rogers, and included
former astronaut Neil Armstrong and former test pilot Chuck Yeager.
The investigation determined that the disaster was caused by the
failure of an “O-ring” seal in one of the two solid-fuel rockets. The
elastic O-ring did not respond as expected because of the cold
temperature at launch time, which began a chain of events that resulted
in the massive loss. As a result, NASA did not send astronauts into
space for more than two years as it redesigned a number of features of
the space shuttle.
In September 1988, space shuttle flights resumed with the successful launching of the Discovery.
Since then, the space shuttle has carried out numerous important
missions, such as the repair and maintenance of the Hubble Space
Telescope and the construction of the International Space Station.
On February 1, 2003, a second space-shuttle disaster rocked the United States when Columbia disintegrated upon reentry of the Earth’s atmosphere. All aboard were killed. Despite fears that the problems that downed Columbia had not been satisfactorily addressed, space-shuttle flights resumed on July 26, 2005, when Discovery was again put into orbit.
The Space Shuttle program formally ended on August 31, 2011 after its final mission, STS-135 flown by Atlantis, in July 2011.
