The oxygen was also used for breathing, and the fuel cells produced water for drinking and environmental control. On Apollo 15, 16 and 17 it also carried a scientific instrument package, with a mapping camera and a small sub-satellite to study the Moon. A major portion of the service module was taken up by propellant and the main rocket engine.
Engineers at Arnold Air Base with an Apollo service module engine Apollo Service Module Propulsion System The service propulsion system ( SPS ) engine was originally designed to lift the CSM off the surface of the Moon in the direct ascent mission mode, [20] The engine selected was the AJ10-137 , [21] which used Aerozine 50 as fuel and nitrogen ...
The Apollo Lunar Module ( LM / ˈlɛm / ), originally designated the Lunar Excursion Module ( LEM ), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only ...
A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton's third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottles as the rocket's pressure vessel.
Saturn V instrument unit. The Saturn V instrument unit is a ring-shaped structure fitted to the top of the Saturn V rocket's third stage ( S-IVB) and the Saturn IB 's second stage (also an S-IVB). It was immediately below the SLA (Spacecraft/Lunar Module Adapter) panels that contained the Apollo Lunar Module.
Air Transport Command ( ATC) was a United States Air Force unit that was created during World War II as the strategic airlift component of the United States Army Air Forces . It had two main missions, the first being the delivery of supplies and equipment between the United States and the overseas combat theaters; the second was the ferrying of ...
S-II. The S-II (pronounced "S-two") was the second stage of the Saturn V rocket. It was built by North American Aviation. Using liquid hydrogen (LH2) and liquid oxygen (LOX) it had five J-2 engines in a quincunx pattern. The second stage accelerated the Saturn V through the upper atmosphere with 1,000,000 pounds-force (4.4 MN) of thrust.
The Redstone was a direct descendant of the German V-2 rocket, developed primarily by a team of German rocket engineers brought to the United States after World War II. The design used an upgraded engine from Rocketdyne that allowed the missile to carry the W39 warhead which weighed 6,900 pounds (3,100 kg) with its reentry vehicle to a range of ...
