Brute (chemical) force is needed to get to orbit and escape velocity. But the longer trip to Mars is best done with gradual (but continuous) accelleration. Then some brute chemical force to decellerate into Mars orbit. Perhaps less brute force to leave orbit and land. Best to send robotic machinery first to dig shelter and storage underground, set up power plants, drill for water supply, build and seed hydroponic farm - get everything ready for the humans who should be sent only later. A very expensive business. Best delayed until we have world peace.
My problem is simple: I just know better than everyone-else!
