The astronauts' cabin
The ascent stage was approximately 2.8 metres high and about 4.0 by 4.3 metres wide. Its pressurised crew compartment had a volume of 6.65 cubic metres. It had an ingress-egress hatch, a docking hatch on top, two triangular windows and control panels. There were no conventional seats; the astronauts operated the Lunar Module while standing.
The engine that took us home
My ascent engine was a fixed, constant-thrust rocket producing approximately 15,000 newtons. It lifted the crew from the Moon and placed the ascent stage into lunar orbit.
Navigation, communication and life support
Radar, an inertial measurement unit containing gyroscopes and accelerometers, and the Apollo Guidance Computer supported navigation. Four reaction-control thruster modules helped control orientation. S-band equipment communicated with Earth; VHF supported communication with the crew and orbiting Command Module. An environmental control system recycled oxygen and regulated temperatures. Six silver-zinc batteries supplied electrical power.
Mission details are based on the NASA/NSSDCA Apollo 11 Lunar Module / EASEP record supplied for this project.
