That run of success bred a measure of complacency, Chiao said.

Here's how the Challenger accident occurred. 28, 1986, NASA's space shuttle Challenger exploded after liftoff, killing seven astronauts and shocking the world.

The program was terminated in 2011, and the remaining vessels were retired, with US astronauts boarding Russian Soyuz capsules for multimillion-dollar trips to the International Space Station ever since. The Challenger catastrophe caused a nearly three-year hiatus in NASA's shuttle program, which resumed in September 1988 with the launch of Discovery.

NASA retired the remaining shuttles in 2011, opting instead for multimillion-dollar rides on Russian Soyuz spacecraft to transport American astronauts to the International Space Station.

The other consideration was that Reagan had his State of the Union speech scheduled for that night, and he wanted to include the launch in his speech.Īfter the failure, NASA's shuttle program was put on hold for over three years, with the second shuttle, Discovery, flying flight on September 29, 1988. The first reason could be that NASA had numerous launches planned that year and wanted to demonstrate that they could achieve their timetables. It's thought that several factors influenced the agency's decision to go through with the launch when it would have been preferable to wait. It was discovered that bad management and a disregard for safety guidelines played a role in the disaster.

This meant that a minor breach of less than an mm allowed a few grams of fuel to escape.ĭue to an unexpected overnight frost, NASA had vetoed engineers' cautions against proceeding with the launch.

The New York Post said Smith, seated on the right side of the flight deck, peered out his window and saw a burst of mist or a fire. The investigation also found no evidence of sudden depressurization, indicating that the passengers were awake and that one astronaut had activated three of their emergency supplies. According to later analysis, it was significantly larger than the three Gs the astronauts prepared to take but still survivable. NASA launched the capsule into the sky at a force of 20Gs.

The Challenger and its seven-member crew were lost seventy-three seconds after launch when a booster rocket failed.
