The only economical way to launch missions to Mars in the near term is with a partially-reusable launcher. Fully expendable ones are to expensive to support high flight rates, while fully reusable ones will cost too much to develop and take too long to design and test. Buzz Aldrin's company, Starbooster Inc., has several partially-reusable designs on their drawing boards. One of them is the Starlifter, with a payload similar to Zubrin's Ares but using reusable, flyback boosters. At some point in the future, these boosters can be mated with a fully reusable core.
