    I'm glad they're performing this mission not only that is a mission explore traveling comets but it's also an example of how we are able to land on asteroids and comets in case of near Earth collision or of collisions. we are capable of destroying an asteroid prior to collision on earth.

    An exciting presentation by George Putic!
    I congratulate those people who began the imagination and then transfer the imagination to reality. No imagination, no dream, no reality.
    What message they will end-up at the end of this mission we do not know yet, but surely it will bring an end of huge curiosity. Will drive to move for the next unknown.

    While it is a very exciting feat by humankind, I still feel that this is going a little bit too far with violating nature. This is carelessness and this may result in this object (comet) losing control and eventually crushing or colliding with our one and only EARTH. LEAVE THAT COMET ALONE, HUMANS! IT'S NOT YOURS!

    Orbiting Rosetta around the comet will Ever-So-Slightly alter the trajectory of the comet. ... Let alone landing upon it.

    I never fail to marvel at the genius of my fellow humans. I wish I was involved in such a noble and intellectual endeavor. Kudos.

    That is admirable! And to think that the landing probe will have to descend on a body with rather miniscule gravity of its own...
