How did the Apollo astronauts move from the command module to Lunar Module?

It was performed shortly after the trans-lunar injection maneuver that placed the Apollo spacecraft on a three-day trajectory to the Moon. The docking created a continuous, pressurized tunnel which permitted the astronauts to transfer internally between the CSM and the LM.

How did the astronauts enter the Lunar Module?

The astronauts used Eagle’s ascent stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned Eagle before they performed the maneuvers that propelled Columbia out of the last of its 30 lunar orbits onto a trajectory back to Earth.

How did the Lunar Module dock with the command module?

The fairing opens up and the CSM detaches, turns around, and docks to the LM. The front of the CM has a hatch that mates with a hatch on the top of the LM. After docking, the CSM pulls the LM away from the S-IVB. This sequence is called the transposition, docking, and extraction maneuver.

How did the Lunar Module take off from the Moon?

Its crew of two flew the complete lunar module from lunar orbit to the Moon’s surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then flew back to the command module, after which it was also discarded….Apollo Lunar Module.
