    If only the commenters shared our enthusiasm....
     
  4. If comets lose ice when they get near enough to the sun, they must reconstitute ice away from the sun, no?
     
  5. I really have no idea, but my question would be, where does the new water come from?

  8. When comets lose a certain amount of their ice they simply disintegrate. If I remember reading this story right the comet that the probe originally was supposed to go to disintegrated like that.

    Nope. Periodic comets that make too many trips near the sun disintegrate.

    Same probe, different comet. From the OPs link:

    "Five years after NASA launched an 800-pound projectile into a comet in an effort to study its contents, the same spacecraft that launched the missile tracked Hartley 2 on Thursday."

    Comet Tempel 1 just after impact:

    HRI_937_1.

  18. This is the most amazing part.

    Man, I love feeling nerdy once in awhile. I'm feeling like those Rush guys right about now. I think I'll go write a prog-rock tune about it.
