Answer to Question 1

It is difficult to get to the Moon, land, take off, and return to Earth all in one trip. The spaceship must carry food, water, and air for a number of days in space plus fuel and rockets for midcourse corrections, landing, and launch back to Earth. This adds up to a ship that is too massive to make a safe landing on the lunar surface. The solution was to take two spaceships to the Moon, one for the round-trip (the command module for long-term living and command center), and one to land in (small lunar landing module built for the short trip between the lunar surface and the command center).

Answer to Question 2
