The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine ...
The circled area on the external tank (ET) is the left bipod foam ramp, and the circled area on the orbiter is the location that was damaged. The Space Shuttle was a partially reusable spacecraft operated by the U.S. National Aeronautics and Space Administration (NASA).
An external tank floats away from the Space Shuttle orbiter. 134 of these tanks were brought to orbital altitude and then released for re-entry (135 total orbital missions minus Challenger) The External Tank for STS-1 is released from the Space Shuttle.
At long last, the final journey of the last space shuttle ever built, Endeavour, and its giant orange external tank are expected to begin this month — the capstone to a historic journey to an ...
Foam fell off of the external tank during liftoff, but did not strike the shuttle. [ 5 ] STS-114 marked the return to flight of the Space Shuttle after the Columbia disaster and was the second Shuttle flight with a female commander (Eileen Collins, who also commanded the STS-93 mission).
The ultimate cause of the accident was a piece of foam separating from the external tank moments after liftoff and striking the leading edge of the orbiter's left wing, puncturing one of the reinforced carbon-carbon (RCC) panels that covered the wing edge and protected it during reentry.
The rockets, external tank and orbiter were installed over a seven-month period, with the twin 149-feet solid rocket boosters assembled between July and November, the external tank in early ...
During re-entry into the Earth's atmosphere, this damage allowed super-heated gases to enter and erode the inner wing structure which led to the destruction of Columbia. It was the seventh instance of a piece of foam, from this particular area of the external tank, breaking free during launch, and the only instance of structural damage as a ...
