Rockets that have gone to the Moon in real life. It can have up to 5 stages, or several modules, for more sophisticated missions, such as an Apollo 11 recreation. If it can get back to Earth, it should have a capsule (that can carry astronauts), parachutes (to slow down into the atmosphere during landing on Earth), and a heat shield to protect it against the reentry heat. Add a pair of landing legs to cushion the impact while landing on the Moon, in case you don't perform a landing burn early enough. It should usually be propelled by a small engine like the Kolibri Engine. The third stage will (or should) be able to land on the moon, and if manned, return to Earth.

It should be propelled by a vacuum engine, like the Valiant Engine or Frontier Engine. The second stage will get the rocket into a parking orbit, shoot the rocket into a trans-lunar injection and optionally put the rocket into a lunar orbit. The boosters can be ignited before the first stage fires its engine(s) to get to orbit. It is also viable, and advised to add a pair of boosters that run out of fuel first to be staged with side separators (see figure 2). Have some fuel tanks, but not too much (6 wide or more is recommended). It should contain at least 1 high-thrust engine ( Hawk Engine, Titan Engine or Frontier engine). This stage will, or should carry the rocket to closely achieve orbit around Earth. A Moon rocket should consist of at least 3 stages: Building a Moon rocket is quite simple compared to building longer-range rockets.
