Because it took NASA two years to investigate the accident, find the cause and develop a solution. Along the way, NASA found hundreds of other potential flaws and took the opportunity to fix them while the Shuttles were grounded.
Challenger was a space shuttle built by NASA. It exploded on January 28, 1986 which was a major disaster. After the accident, NASA's Space Shuttle fleet was grounded for almost three years.
Discovery was the next shuttle to launch. Over 2 years later.
3 years
Never. The Challenger space shuttle was destroyed in the 1986 disaster and was not rebuilt. The first shuttle mission after the Challenger disaster was on September 29, 1988, more than two years after the incident. That mission was flown by the shuttle Discovery.
Two and a half years. :~)
Discovery Discovery was launched two years before the Challenger blew up. The replacement was "Endeavour"
NASA was halted for 3 years in the 80s because of negative public opinion and criticism of the Space Shuttle program. With the Challenger incident in 1986, safety had to be reviewed.Sources: Wikipedia: Criticism of the Space Shuttle ProgramFollowing the Challenger accident in 1986, missions were halted pending safety review. This hiatus became lengthy and ultimately lasted almost three years as arguments over funding and the safety of the program continued
1986 was 28 years ago. Some major events of 1986 include the nuclear accident in the Soviet Union's Chernobyl power station, the explosion of the space shuttle Challenger, and the death of Georgia O'Keeffe.
No, but it did ground the program for 2 years.
HST's initial launch was planned for October 1986; however, the Challenger accident, which occurred in January that same year, halted all Shuttle missions for the next 2 years while the investigation continued.
Space Shuttle Challenger and Space Shuttle Endeavor.
None of them crashed. Space Shuttle Challenger broke apart in 1986 due to a SRB explosion. Space Shuttle Columbia broke apart during reentry in 2003 due to a whole in it's left wing from foam from the ET hitting it during launch.
