In 1976, the National Aeronautics and Space Administration (NASA)unveiled the world’s first reusable manned spacecraft, known as the space shuttle. Five years later, flights began when the space shuttle Columbiaembarked on a 54-hour mission. Launched by two solid-rocket boosters and its main engines, the aircraft-like shuttle entered into orbit aro...
The mission’s launch from Kennedy Space Center at Cape Canaveral, Florida, was delayed for six days due to weather and technical problems. The morning of January 28was unusually cold, and engineers warned their superiors that certain components—particularly the rubber O-rings that sealed the joints of the shuttle’s solid rocket boosters—were vulner...
Shortly after the disaster, President Ronald Reagan appointed a special commission to determine what went wrong with Challenger and to develop future corrective measures. Headed by former secretary of state William Rogers, the commission included former astronaut Neil Armstrong and former test pilot Chuck Yeager. Their investigation revealed that t...
After the accident, NASA refrained from sending astronauts into space for more than two years as it redesigned a number of the shuttle’s features. Flights began again in September 1988 with the successful launching of Discovery. Since then, the space shuttle has carried out numerous important missions, including the repair and maintenance of the Hu...
On January 28, 1986, the Space Shuttle Challenger broke apart 73 seconds into its flight, killing all seven crew members aboard. The spacecraft disintegrated 46,000 feet (14 km) above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 a.m. EST (16:39 UTC).

- The Challenger didn’t actually explode. A cloud of fire engulfed the space shuttle just 73 seconds after liftoff, at an altitude of some 46,000 feet (14,000 meters).
- The astronauts aboard the shuttle didn’t die instantly. A seal in the shuttle’s right solid-fuel rocket booster designed to prevent leaks from the fuel tank during liftoff weakened in the frigid temperatures and failed, and hot gas began pouring through the leak.
- Relatively few people actually saw the Challenger disaster unfold on live television. Though popular wisdom about the 30-year-old tragedy holds that millions of people watched the Challenger’s horrific fate unfold live on television—in addition to the hundreds watching on the ground—the fact is that most people watched taped replays of the actual event.
- Some suggested that the White House pushed NASA to launch the shuttle in time for President Ronald Reagan’s State of the Union address. NASA officials apparently felt intense pressure to push the Challenger’s mission forward after repeated delays, partially due to difficulties getting the previous shuttle, Columbia, back on the ground.
