Online Apollo Guidance Computer Simulator


Moonjs is an online Apollo Guidance Computer (AGC) simulator. It is a port of Virtual AGC by Ronald Burkey from C to javascript/asm.js using the Emscripten compiler. AGC was the main computer system of the Apollo program that successfully landed 12 astronauts on Moon.

Dynamic Out-The-Window Scenes

Dynamic out-the-window scenes are provided through an infinity-optics display system during the simulated flights. A five-ton system of lenses, mirrors, and mounts made up the visual display system attached to the LMS crew station. The heart of the simulator was a crew station that resembled in all details the actual spacecraft.

The landing and ascent model generates the lunar surface’s simulated views from approximately 8,000 feet almost to touchdown. And are transmitted to the visual display system through high-resolution television. The images are available to either forward or the window of the LMS crew station.

Lunar Module Mission Simulator

The Lunar Module (LM) Mission Simulator is a large, complex machine, and it was in operation at the Kennedy Space Center between 1968 and 1972. Every Apollo astronaut used the LM simulator to train for landing on the Moon before their mission. Only one was built, and, remarkably, it survived in good condition up to this date.

The LM simulator consists of a cabin (LM Ascent Stage with complete original interior), four large rear-projection projectors and screens mounted outside the windows, an operator console, tape-drive computers, and a simulated lunar surface model and camera. At the operator’s console, instructors could introduce malfunctions into the simulated mission the astronauts were running inside.

They devised theoretical designs and incrementally developed the spacecraft simulators based on new data from each Apollo mission leading up to Apollo 11’s landing on the Moon. The Lunar Module Simulators in Houston and Cape Kennedy were produced by the Link Group of Singer General Precision Systems.

Apollo 18 is an early space mission simulation by Artech, converted from the C64 to the IBM-PC by Ted Gruber Software. Problems might occur on fast computers. Try a slow-down util. Also don't forget to download the manual, you won't get far without it.
