what happened to the challenger space shuttle

The Space Shuttle Challenger broke apart 73 seconds after liftoff on January 28, 1986, killing all seven crew members. The disaster was caused by a failure in the solid rocket booster O-ring seal, which let hot gas escape and destroy the shuttle stack.

What happened

Challenger launched from Cape Canaveral and then failed shortly after takeoff during ascent. The vehicle broke apart in the sky over the Atlantic Ocean, and the mission’s crew was lost.

Why it failed

Investigations concluded that the primary problem was the O-ring seals in the right solid rocket booster. Cold temperatures that morning made the rubber seals less flexible, which helped the hot gases leak through and trigger the structural failure.

Aftermath

NASA suspended shuttle flights for a long period after the disaster, and the accident led to major changes in shuttle safety and oversight. Challenger became one of the most remembered tragedies in U.S. space history.
