Romulus and Remus

The rocket used to launch Romulus and Remus is a combination of the NASA's SLS and Blue Origin's New Glenn. It is a two-stage vehicle with a pair of boosters. The boosters would be ejected fairly early, but the first stage would push the craft out of the atmosphere. After burning the first stage, the second stage would then complete an injection burn. Using the gravity of the moon the craft would leave the Earth's sphere of influence. Romulus (the main habit vehicle) and Remus (the lander) would deploy from the second stage and complete mid-course corrections to Mars. Romulus is equipped with an array of five, large ion thrusters, which are very slow, but very efficient. After reaching Mars, a team of three (leaving one astronaut behind) would enter the Remus (the lander). Remus would then descend to the surface of Mars and land. the group of three would then be able to explore for at most two sols. The crew would then renter Remus, launch, leaving the legs behind.
