https://en.wikipedia.org/wiki/Nuclear_pulse_propulsion https://en.wikipedia.org/wiki/Nuclear_pulse_propulsion With nuclear pulse propulsion, we could send a craft to Mars in 2-3 weeks, safely, any time, and on the cheap. The mass that can be transported is quite enormous, so we could piecemeal launch the components of a huge habitat and vast amounts of supplies into an outer orbit of Earth, robotically load them onto the pulse ship, and then shoot that baby to Mars. Probably the slowest part of the plan would be launching the stuff into orbit. They scrubbed the idea of launching using nuclear pulse propulsion because of the dangers of radioactive fallout. Too bad, because that would have made things even simpler.
