    How would we travel to Mars?

    Hi all!
    I've currently been discussing this with some people on another forum, and I'm under the impression it would be more practical to launch a Mars mission straight from Earth, as opposed to launching from the Moon as they argue. Anyone have any links that describe how we are "planning" to travel to Mars, or can anyone discuss the pros and cons of each scenario, because I don't know a whole lot about the subject.

    Thanks

    i "think" the plan is tot launch it on a few rockets from earth, assemble the interplanetary craft in earth orbit, then go to Mars from there.

    The "moon, then Mars" idea is not a literal path to follow. The idea is to develop the technologies by going to the moon first, but not to use the moon as a launch point for a Mars trip.

    In the long term the Moon may be the stepping board to the planets. That's long term though, after we get an established Lunar infrastructure.

    The future version of the U.N. may well decide that our uber monstrous fusion drives should not activate within the Moon's orbit for planetary security and for the general health of plant and animal life.

    We're gonna be kicking out some serious exhaust some day.

    Most (not all) Mars mission studies of the past 50 years can be found at http://astronautix.com/craftfam/martions.htm - none start from the Moon.

    My favorite. http://astronautix.com/craft/proeimos.htm

    The skin of your teeth method
    http://astronautix.com/craft/flem.htm

    "Titus calculated that using FLEM with a nuclear thermal upper stage, the total spacecraft mass for a manned landing expedition could be kept to 118 metric tons, meaning a single Saturn V launch could mount a Mars landing mission."

    To Mars with a single Ares V?

    It might be this or nothing.

    Deimos was cool, but then anything with ROMBUS is.

    FLEM is the sort of thing that just might be possible for a private consortium in a few decades, especially if they cut the crew to two and used chemical.

    My favourite is this one: http://astronautix.com/craft/marsoz.htm

    Might I recommend The Case for Mars by Robert Zubrin. His book won kudos from Carl Sagan and Sir Arthur C. Clarke.

    Excitedly!
    The greatest journey of all time, for all to see
    Every mission makes our dreams reality
    And our destiny begins with you and me
    Through all space and time, the achievement of mankind
    As we sail the sea of discovery, on heroes’ wings we fly!
