How to Navigate a Spacecraft to Mars

EccentricAnomaly writes "JPL has an article on how to design trajectories to Mars with the porkchop plot. They use an interesting analogy between reading these plots and divining the future from animal entrails. JPL also has the most excellent Basics of Spaceflight, which is an easy to understand tutorial on how to explore deep space."

  1. Stephen King, author, dead at age 54 by Anonymous Coward · · Score: -1, Troll

    I just heard sad news on talk radio - Horror/fiction writer Stephen King was found dead in his Maine house this morning. I'm sure we'll all miss him - even if you didn't read his books you've probably enjoyed one of his movies. Truly an American icon.

    The worst terrorist attack in recorded history occurred in September, and now we
    're involved in a WAR against Islam and you people have the gall to be discussing navigation to Mars???? My *god*, people, GET SOME PRIORITIES!

    The bodies of the thousands of innocent civilians who died (and will die) in these unprecedented events could give a good god damn about navigating to Mars (but admittedly, many might find it cool), your childish Lego models, your nerf toy guns and whining about the lack of a "fun" workplace, your Everquest/Diablo/D&D fixation, the latest Cowboy Bebop rerun, or any of the other ways you are "getting on with your life" (here's a hint: watching Cowboy Bebop in your jammies and eating a bowl of Shreddies is *not* "getting on with your life"). The souls of the victims are watching in horror as you people squander your finite, precious time on this earth playing video games!

    You people disgust me!
