Apollo Guidance Computer, 1962-1972
The Apollo Guidance Computer provided spacecraft guidance, navigation, and control during all of NASA’s Apollo Moon missions. It was developed under the leadership of Dr. Charles Stark Draper at the MIT Instrumentation Lab - now Draper Laboratory. This pioneering  digital flight computer was the first real-time embedded computing system to collect data automatically and provide mission-critical calculations for the Apollo Command Module and Lunar Module.

In the space below the line, please describe the historic significance of this work: its importance to the evolution of electrical and computer engineering and science and its importance to regional/national/international development.

AGC was a true pioneer: a mission-critical real-time, embedded digital computer system built using commercial integrated circuits. AGC and the associated guidance, navigation and control system components made possible the lunar rendezvous mode trajectory used by the Apollo program to put the first human beings on the moon and return them safely to earth. 1 The AGC performed flawlessly on 15 manned flights, including nine flights to the moon and six successful lunar landings. It was used for three manned Skylab missions and navigated the final Apollo spacecraft to a docking with a Russian Soyuz spacecraft in 1975. 2
Astronauts repeatedly worked the AGC, achieving flawless moves and life-critical lunar landings. For additional information, see reference  3.
