While habitats are definitely the way to go long term (planets are just sooo inefficient!), Mars still has some useful features: - while the atmosphere/graviti combination is a bit annyoing, the atmosphere still enables some nice propelantless manuevers (aerobraking, aerocapture, plane changes, etc.) - the gravity should enable reusable single-stage-to-orbit rockets with current technology, unlike on Earth - day length & atmosphere reduce the insane temperature swings you get on the moon (and no 14 day nights) and also makes the dust particles less sharp & thus safer - powered atmopsheric flight is possible (already demonstrated) - a lot of elements up for grabs bound in rocks & the atmosphere (carbon, oxygen, hydrogen, chlorine, iron,...) - two ready to use asteroid moons already in low Mars orbit - another body that could host a space elevator built with current materials
