Space Shuttle Challenger (NASA Orbiter Vehicle Designation: OV-099) was NASA's second Space Shuttle orbiter to be put into service, after Columbia. Its maiden voyage was on April 4, 1983, and it made eight further round trips to low earth orbit before breaking up 73 seconds after the launch of its tenth mission, on January 28, 1986, killing all 7 crew members. (For more on the Challenger disaster, see Space Shuttle Challenger disaster.) It would later be replaced by the space shuttle Endeavour, which would be launched six years after the 51-L disaster.

Challenger was constructed using a body frame (STA-099) that had initially been built as a test article. STA-099 had not been meant for spaceflight, but NASA discovered that recycling it would be cheaper than refitting the test shuttle Enterprise (OV-101) to be spaceworthy, as originally planned. The spacecraft was named after a British corvette which carried out a pioneering global marine research expedition in the 1870s[1].

Challenger, along with Discovery was modified at KSC to be able to carry the Centaur upper-stage in its payload bay. Had STS-51-L been successful, Challenger's next mission would have been the deployment of the Ulysses probe with the Centaur to study the polar regions of the Sun.

Challenger was one of two space shuttles destroyed in an accident during a mission, the other being Columbia. The collected debris of the vessel is currently stored in decommissioned missile silos at Cape Canaveral Air Force Station. From time to time, further pieces of debris from the orbiter wash up on the Florida coast. When this happens, they are collected and transported to the silos for storage.

Flights

Space Shuttle Challenger flew 10 flights, spent 62.41 days in space, completed 995 orbits, and flew 25,803,940 statute miles in total, including its final mission.

Loss of Challenger

During the second minute of its tenth mission in January 1986, the Challenger was destroyed, due to the failure of an SRB seal.
