Apollo 13 (April 11–17, 1970) was the seventh crewed mission in the Apollo space program and would have been the third Moon landing.The craft was launched from Kennedy Space Center on April 11, 1970, but the landing was aborted after an oxygen tank in the service module (SM) exploded two days into the mission, disabling its electrical and life-support system.
The remaining engines on the second and third stages were burned a total of 34 seconds longer to compensate, and parking orbit and translunar injection were successfully achieved. It was later determined that the shutdown was caused by pogo oscillation of the engine. [47] [48] [49] Equipment failure 13 April 1970: Apollo 13
Pogo oscillation is a self-excited vibration in liquid-propellant rocket engines caused by combustion instability. [1] The unstable combustion results in variations of engine thrust, causing variations of acceleration on the vehicle's flexible structure, which in turn cause variations in propellant pressure and flow rate, closing the self-excitation cycle.
Apollo 13 was slated to be the third landing on the moon after Apollo 8 (1968) and Apollo 12 (1969). Launched on April 11, 1970, the crew was led by commander Lovell, along with command module ...
A new documentary chronicling the events surrounding the Apollo 13 mission, in which three astronauts found themselves stranded in space following a catastrophic explosion, is being released on ...
In August 2014, it was revealed that parts of two different F-1 engines were recovered, one from Apollo 11 and one from another Apollo flight, while a photograph of a cleaned-up engine was released. Bezos plans to put the engines on display at various places, including the National Air and Space Museum in Washington, D.C. [ 29 ]
After the landing by Apollo 12, Apollo 20, which would have been the final crewed mission to the Moon, was canceled to allow Skylab to launch as a "dry workshop" (assembled on the ground in an unused S-IVB Saturn IB second stage). The next two missions, Apollos 18 and 19, were later canceled after the Apollo 13 incident and further budget cuts ...
Apollo 13's story was told in the 1994 book “Lost Moon: The Perilous Voyage of Apollo 13,” co-authored by Lovell, and in the 1995 movie “Apollo 13,” where Gary Sinise played Mattingly.
