![]() ![]() To learn more about these space shuttle disasters, listen to today's episode of "This Day In Weather History. The Space Shuttle program officially ended on August 31, 2011. Similarly, the program went on a 32-month hiatus after the Challenger disaster.īoth tragedies led to in-depth analysis of NASA's structure, as both incidents were highly impacted by human error. Aerodynamic forces that far exceeded what the shuttle could withstand then caused the spacecraft to break apart.Īfter the Columbia disaster, NASA's Space Shuttle program went on hiatus for 29 months. ![]() ![]() As more gases vented from the breach, they burned a hole in the external fuel tank, causing it to explode. With all of the extra maneuvering the booster rockets were forced to perform, the stresses tore open that new seal. Unfortunately, the shuttle then passed through several layers of severe clear air turbulence. These burning-hot gases quickly vapourized the rubber to form a new, tighter seal that temporarily stopped the leak. As a result they could not expand and contract quickly enough to maintain their seal, and they allowed hot exhaust gases to escape from between the lower rocket sections. Courtesy of NASAĪs the shuttle ascended towards space, the O-rings on the right booster rocket were still very cold. In the front row from left to right: Michael J.

These rings were not designed to withstand the unusually cold conditions that were experienced at the launch site, in Cape Canaveral, Florida, on the morning of January 28, 1986. The boosters had large rubber O-rings to seal the joints between the rocket sections. The root of the Challenger disaster lay in an engineering flaw in its solid rocket boosters. In 1986, the Space Shuttle Challenger exploded 73 seconds after take-off, on its tenth mission to space. Temperature considerations have been a factor in both of NASA's fatal disasters. The light-coloured triangle visible at the base of the strut near the nose of the orbiter is the left bipod foam ramp which damaged the wing." Courtesy of NASA "Columbia lifting off on its final mission. However, the very foam that was there to help prevent damage ended up dooming the shuttle's mission. Ice, if it were to form on the tank, can break off and damage the shuttle during lift-off. The thermal foam is used to insulate the tank so ice can't form when it's full of liquid hydrogen. When Columbia was launching, a piece of insulating foam from its main fuel tank broke off and damaged the left wing. The incident on Februoccurred due to hot atmospheric gases penetrating the left wing and destroying the wing's interior, ultimately leading the spacecraft to veer out of control and break apart.

It completed 27 successful missions over 22 years. On February 1, 2003, as the Space Shuttle Columbia reentered Earths atmosphere at the end of a two-week scientific mission, it suddenly broke apart in the skies over Texas. The Space Shuttle Columbia launched for the first time on April 12, 1981. On Saturday, February 1, 2003, the Space Shuttle Columbia disintegrated as it re-entered the atmosphere.
