Hauling 1M bodies to Mars is not an efficient way to populate the planet. Unless and until we have a reliable and cost effective artificial womb, the limiting factor is the ability to have babies. So we should start with, say, 100 very intelligent and skilled, and physically capable women. Each of them should be inpregnated on Mars with frozen, fertilized ova from a stock representing the genetic diversity of Earth. Did I mention that the ova should all be females? So assuming that each woman can bear 7 children in her lifetime (a reasonable average based on good medical care and historic norms) and that the generation time is 20 years, it would take about 125 years to reach a population of 1 million. During that 125 year period the women would be busy building a modern civilization while also devoting a major portion of their time ot childcare. Constant resupply of food and manufactured products would have to be provided from Earth. Oh, and I guess they could have a few males around... you know... for entertainment.
