This video was produced by Grumman to celebrate the 20th anniversary of the Apollo 11 moon landing.Scenes of Lunar Module manufacturing are shown. The video also features comments by several of the Grumman engineers who worked on the Lunar Module, such as Thomas Kelly, as well as NASA administrators, such as Robert Gilruth.

Lunar Module description:
Ascent stage
The Ascent stage contained the crew cabin; environmental control (life support) system; instrument panels; overhead hatch/docking port; forward EVA hatch; sixteen Reaction Control System (RCS) thrusters (identical to those used on the Service Module) mounted in four quads; rendezvous radar; VHF and S-band communications equipment and antennas; guidance and navigation systems (primary and backup); active thermal control system (an ice sublimator); Ascent Propulsion System (APS) engine; and enough fuel, battery power, cooling water, and breathing oxygen to return to lunar orbit and rendezvous with the Apollo Command/Service Module. The ascent stage also carried lunar rock and soil samples back with the crew, as much as 238 pounds (108 kg) on Apollo 17. Crew: 2 Crew cabin volume: 235 cu ft (6.7 m3) Height: 9.29 ft (2.83 m) Width: 14.08 ft (4.29 m) Depth: 13.25 ft (4.04 m) Mass including fuel: 10,300 lb (4,700 kg) Atmosphere: 100% oxygen at 4.8 psi (33 kPa) Water: two 42.5 lb (19.3 kg) storage tanks Coolant: 25 pounds (11 kg) of ethylene glycol/water solution Thermal Control: one active water-ice sublimator RCS propellant mass: 633 lb (287 kg) RCS thrusters: sixteen x 100 lbf (440 N) in four quads RCS propellants: Aerozine 50 fuel / nitrogen tetroxide(N2O4) oxidizer RCS specific impulse: 290 s (2,840 N·s/kg) APS propellant mass: 5,187 lb (2,353 kg) APS engine: Rocketdyne RS-18[10] APS thrust: 3,500 lbf (16,000 N) APS propellants: Aerozine 50 fuel / nitrogen tetroxide oxidizer APS pressurant: two 6.4 lb (2.9 kg) helium tanks at 3,000 pounds per square inch (21 MPa) APS specific impulse: 311 s (3,050 N·s/kg) APS delta-V: 7,280 ft/s (2,220 m/s) Thrust-to-weight ratio at liftoff: 2.124 (in lunar gravity) Batteries: two 28--32 volt, 296 ampere-hour silver-zinc batteries; 125 lb (57 kg) each Power: 28 V DC, 115 V 400 Hz AC
Descent stage
The Descent stage contained the landing gear; EVA ladder; landing radar; Descent Propulsion System (DPS) engine and fuel to land on the Moon. It had several cargo compartments with replacement Portable Life Support System (PLSS) batteries and lithium hydroxide canisters; the Apollo Lunar Surface Experiment Package ALSEP; Mobile Equipment Cart (a hand-pulled equipment cart used on Apollo 14) or the Lunar Rover (used on Apollo 15-17); deployable S-band antenna (Apollo 11-14); surface television camera; surface tools; and lunar sample collection boxes. The descent stage carried consumables for the lunar stay: batteries; oxygen and water for drinking and cooling. The No. 1 landing gear leg carried an aluminum plaque near the ladder commemorating each landing flight, listing the names of the astronauts, and in the case of the first and last, the President of the United States (Richard M. Nixon). Height minus landing probes: 8.59 ft (2.62 m) Width/depth minus landing gear: 12.83 ft (3.91 m) Width/depth incl. landing gear: 31.0 ft (9.4 m) Mass including fuel: 22,783 lb (10,334 kg) Water: one 151 kg (330 lb) storage tank DPS propellant mass: 18,000 lb (8,200 kg) DPS thrust: 10,125 lbf (45,040 N), throttleable between 10% and 60% of full thrust DPS propellants: Aerozine 50/nitrogen tetroxide DPS pressurant: one 49-pound (22 kg) supercritical helium tank at 1,555 psi (10.72 MPa) DPS specific impulse: 311 s (3,050 N·s/kg) DPS delta-V: 8,100 ft/s (2,500 m/s) Batteries: four (Apollo 9-14) or five (Apollo 15-17) 28--32 V, 415 A·h silver-zinc batteries; 135 lb (61 kg) each

Wow this is historical. I am a big fan of NASA.
So much work that is now forgotten that went into putting humans on the Moon.
