Every time I hear about people wanting to have a manned trip to Mars, I have to roll my eyes. It seems that we are just nowhere near what is needed to actually perform one, namely a long term space habitat probably needing spin gravity, minimal leakage, and propulsion, especially assuming that such things would need to be tested and the actual Mars shot would be far down the mission scale (comparable how Apollo 11 was the one that made it to the surface of the moon). Talk of a one way trip sound even sillie
To expand on this for general conversation. Looking at orbital physics, it seems that a Mars mission will take about two years. 7-9 months to get to Mars, a stay of several months then another 7-9 months back at the optimal times in the Earth-Mars orbits. Leaving at other times or attempting quicker transit speeds greatly increases the distances or fuel needed as to be prohibitive. Therefore, we'll need a long term space habitat for the astronauts. How many we'll need is a questions but I would guess that t
Check out Dr. Robert Zubrin's Mars Direct reference mission for a low cost, sustainable manned Mars program that doesn't require any technological breakthroughs.
