    Sure, there's nothing wrong with the cgs system (centimeters, grams seconds).
    I like it beter than mks mostly because 1 cm^3 = 1 ml = 1 gram (water).
    Much better than 1 m^3 = 1000 l = 1000 kg, IMVHO.
    Besides, when your talking space flight, everything is exponents anyhow.

    Anyone remember how fast Helios B went? I think it was around 57,000 miles per hour.

    OK, very roughly:
    Earth 1.52E13 cm from Sun (max)
    Mars 2.06E13 cm from Sun (min)
    so min of 5.4E11 cm distance between them.

    2.7E12 cm = a/2*t^2

    About a 60th of a G? Hmmm, kinda low, but since it is only for two weeks, I doubt someones bones would completely deteriorate. No, not puree, but you should exersise, or else that 1/3G on Mars will seem a little more.

    So, Here I am reading an article about how LJ isn't being published, staring at a banner ad for, you guessed it, LJ.
