Orion Spacecraft in Lunar Orbit Napkin

The Orion Multi-Purpose Crew Vehicle is the new interplanetary craft designed to carry four astronauts beyond low Earth orbit to the Moon, Mars and asteroids throughout the Solar system. Orion is mated to the SLS Space Launch System, a rocket more powerful than the mighty Saturn V or the Space Shuttle. The complete spacecraft will consist of a command module and service module. The command module looks like a much larger and modernised version of the Apollo space capsule. In a pinch, Orion can also make trips to and from the International Space Station.
