I'm thoroughly impressed with the calculations involved in all of this. The fact that we're on one wobbly, fast-moving planet looking at another fast-moving, wobbly planet predicting the trajectory of a sputtering fast-moving comet and re-calibrating the orbits of mars-orbiting telescopes so their out of danger but looking at the comet while it goes past is just astounding. I won't be impressed, however, if said comet takes out curiosity. Would give a good first-person shot of what planetary extinction looks like though.
