The Apollo Guidance Computer (AGC) was a revolutionary piece of technology used during the Apollo missions to the Moon. Developed by MIT Instrumentation Laboratory, it was one of the first computers to use integrated circuits, making it compact and efficient for space travel. The AGC was responsible for navigation, guidance, and control of the Apollo spacecraft, allowing astronauts to perform complex maneuvers during their missions. The AGC operated using a simple user interface, featuring a display and a keypad for astronauts to input commands. It ran software that was specifically designed for the unique challenges of space travel, ensuring that the spacecraft could safely land on the lunar surface and return to Earth. The success of the AGC played a crucial role in the achievements of the Apollo program.
