On January 28, 1986, the American shuttle Challenger was completely destroyed 73 seconds after liftoff, a catastrophic end to the shuttle's tenth mission. This disaster took the lives of all seven astronauts aboard.

This tragedy and the aftermath received widespread media coverage and urged NASA to temporarily suspend all shuttle missions.
NASA introduced to the world, in 1976, the first reusable manned spacecraft. This became known as the space shuttle. Five years later, in 1981, space flights began with Columbia.

Columbia only had two crewmembers, Commander John Young and Pilot Bob Crippen. Columbia completed 27 missions before disintegrating in the descent of its 28th mission in 2003. Challenger was NASA’s second space shuttle. Its first mission was April 4, 1983. Challenger made nine journeys into space, before that tragic January day.
In 1986, the Challenger crew met at NASA's Kennedy Space Center for countdown training. The crew of this shuttle included two civilians and five astronaut members: “Teacher-in-Space” payload specialist Christa McAuliffe; payload specialist Gregory Jarvis; and astronauts Judith A.

Yet every January, NASA pauses to remember the last crew of Challenger, and the other crews lost in pursuing space, on a NASA Day of Remembrance. This tragic day will always be remembered as the day that changed space program forever.
