Ares V
The Ares V was planned to be able to carry about  to Low Earth orbit (LEO), and  to the Moon.  Upon completion the Ares V was planned to be the most powerful rocket ever built, lifting more into orbit than even the Saturn V.  Ares V, Ares IV, and Ares I are named after Ares, the Greek god, which is the equivalent to the Roman god Mars.
