The LM was the last of the Apollo “hardware” to be developed. Its start had been delayed while NASA made up its mind to take the lunar-orbit meeting approach and thus require a vehicle like the LM for a landing. A contract with the prime builder was signed on January, 1963, almost two years after the Apollo project began. The LM was tested several times in space.<ref>''Moon Race: The History of Apollo'' DVD, Columbia River Entertainment (Portland, Oregon, 2007)</ref> Finally, on July 20, 1969 the [[Apollo 11]] LM Eagle made the first manned lunar landing.

As Apollo missions progressed, Apollo 12, 14, 15, 16, 17 had lunar landings using their LMs.  [[Apollo 13]] had a terribly dangerous accident when an oxygen tank exploded. The [[Apollo 13]] Lunar module, called ''Aquarius'', played an unexpected role in saving the lives of the three astronauts after the explosion.<ref name = "Cass 1">{{cite web|last=Cass|first=Stephen|title=Houston, we have a solution|url=https://spectrum.ieee.org/tech-history/space-age/apollo-13-we-have-a-solution|date=April 1, 2005|accessdate=August 30, 2019|website=IEEE}}</ref>
