That is debatable at best, a crewed flight to mars is 8 months, crew of 3 You have roughly 40t at best for a craft that needs to land there. quick google. astronauts need around 1.7kg of food per day, x3 crew, x(8x30) days is: thats 1200 kg of food - one way - just to get there food. And then you are doing to do what exactly? > the rest of the plan revolved around using Apollo hardware, with some modification, for both transport and habitats(re-use of empty stages featured prominently). This is basically handwaving problems away, massive problems. The best I can agree is that a crewed fly-by could have been possible. But landing on mars would mean death sooner or later.
