Apollo 11 Lunar Module Eagle

After Armstrong and Aldrin rejoined Collins in lunar orbit, Eagle was jettisoned and its eventual fate is unknown; it likely crashed somewhere on the Moon's surface. NASA did not track its final impact site. No Apollo lunar module ascent stage was returned to Earth.

The Lunar Module was designed and built by Grumman Aircraft Engineering Corporation in Bethpage, New York, under a contract awarded in 1962. It was the first crewed spacecraft designed to operate only in space. The descent stage engine was built by TRW Systems.

Eagle consisted of a descent stage and an ascent stage, standing roughly 23 feet tall and weighing about 33,000 pounds fully fueled at launch from Earth. The ascent stage alone, which returned the crew to orbit, was much lighter. The crew cabin had roughly the interior volume of a small car.

When the descent engine shut down on July 20, 1969, Armstrong radioed Mission Control in Houston with the message 'Houston, Tranquility Base here, the Eagle has landed.' The landing site was in the Moon's Mare Tranquillitatis. Aldrin and Armstrong spent about 21.5 hours on the surface before ascent.
