In the beginning, president Kennedy made a bet an american would land a man on the Moon before 1970 an return safely back to Earth.
The came the Lunar Module.

What is truly amazing is how the LM evolved:
Early it was thought only one astronaut would step on the Moon (the other would remain aboard like the commander did with Gemini) and he would go down using a rope!! The LM had 2 docking hatches and was very heavy.
Then the hatch was replaced by a square door.
Both astronauts would go down on a ladder.
They'd do some science.
Here comes Apollo 11...
The Apollo J flight: 3 days, 3 moonwalks, removable spacesuits, a rover and miles of explored areas!
All of this while the LM kept shrinking its mass and transfering unnecessary mass (fuel) into science packages.

From one astronaut for a few minutes to two astronauts for a total of 22 hours outside and traveling for 35 km.
And yet, the same Saturn V rocket was used.

Can a new lunar module go through such steps? How about an unpressurized module?
Wouldn't that be great to view from a CEV? You'd see (from a controled camera on board the CEV) spacesuited astronauts separating from the CEV, with the Moon as a background and, who knows, we'd be able to follow the entire landing sequence from the CEV with sharp images (no atmosphere to blur the view) of the spacesuited astronauts bracing for touchdown! Of course the lander and the astronauts themselves would be equipped with cameras too.
