The Charles Stark Draper Laboratory guides research into space, under water, and across continents. The not-for-profit corporation develops guidance, navigation, and control technologies for aircraft, submarines, missiles, and spacecraft. It works with NASA, the US Department of Defense, and commercial businesses to develop technologies and fabricate prototypes. The organization also solves healthcare problems with its work in biomedical engineering. The lab boasts more than 850 engineers and scientists. Originally known as the Instrument Lab, the laboratory was renamed in 1970 and became an independent institution three years later.
