The only problem with that is we would have to get a lot better at building rockets first. Currently it seems to take a fairly large crew (and clean rooms and a lot of care) to get a successful launch off earth, and even then there are often glitches. Getting the Moon lander to launch from the moon surface was easier due to lower gravity and no atmosphere. But I can't imagine a rocket on Mars sitting there for a couple years with an automatic fueling station, and having it launch successfully after getting battered by dust storms and any other corrosives present on Mars.
