  1. Someday, someone will go to Mars and other places in the Solar System. But I don't think anyone should go until several things happen. The first is travel times have to come down to 60 days maximum. Second is some form of magnetic shielding needs to be developed to help protect crew and passengers. Third is more advanced pressure suits. The best option here IMO is the Mechanical Counterpressure Suit. Or the Space Activity Suit as some call it. These should allow a far greater degree of mobility and dexterity for the user. Fourth is some sort of reliable and safe nuclear power unit. This is pretty much a given for the faster trip times mentioned in #1. Fifth is a source of propellant that can be obtained at Mars. The best source for this may actually be the Martian moons. Sixth is a Mars SSTO (Single Stage To Orbit) re-usable lander. And #7. Ships designed to provide spin gravity. This would allow mission personnel to adapt to 1/3rd gee on the trip out. On the return trip the spin rate could gradually be increased to 1 gee to adapt the crew to returning to Earths gravity. This would also negate the effects of prolonged weightlessness. Why there hasn't been research into spin gravity in the past is beyond me. It almost seems as if NASA is fixated on zero gee. One way to make ships with spin gravity is through the use of tethers
