Apollo 9 (March 3–13, 1969) was the third human spaceflight in NASA's Apollo program.Flown in low Earth orbit, it was the second crewed Apollo mission that the United States launched via a Saturn V rocket, and was the first flight of the full Apollo spacecraft: the command and service module (CSM) with the Lunar Module (LM).
Endeavour, which was named for the space shuttle Endeavour, had previously served as call signs for both an Apollo spacecraft and the spacecraft's namesake shuttle. [6] The name Freedom honors Freedom 7 , the space capsule used by Alan Shepard 's Mercury Redstone 3 , the first United States human spaceflight mission.
A Saturn V rocket launches Apollo 11, 1969. Saturn V launch vehicles and flights were designated with an AS-500 series number, "AS" indicating "Apollo Saturn" and the "5" indicating Saturn V. [67] The three-stage Saturn V was designed to send a fully fueled CSM and LM to the Moon. It was 33 feet (10.1 m) in diameter and stood 363 feet (110.6 m ...

The booster systems engineer monitored and evaluated performance of propulsion-related aspects of the launch vehicle during prelaunch and ascent. During the Apollo program there were three booster positions, who worked only until trans-lunar injection (TLI) was complete; after that, their consoles were vacated. Booster had the power to send an ...
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
Launch of AS-506 space vehicle on July 16, 1969, at pad 39A for mission Apollo 11 to land the first men on the Moon. The Apollo program was a United States human spaceflight program carried out from 1961 to 1972 by the National Aeronautics and Space Administration (NASA), which landed the first astronauts on the Moon.

A major portion of the service module was taken up by propellant and the main rocket engine. Capable of multiple restarts, this engine placed the Apollo spacecraft into and out of lunar orbit, and was used for mid-course corrections between the Earth and the Moon. The service module remained attached to the command module throughout the mission.
