Am I dumbfounded in awe at being able to hit the all time smallest bullseye? Absolutely. Yeah, the rest of the stuff was cool, relaying stuff through satellites, taking pictures of Curiosity after parachute deployment - all pretty nifty. But even hurling a smart bullet to hit their injection window of just a few miles across while travelling over 12,000 miles an hour? That's over 3 miles a second.
Miss that, it doesn't matter what whizbang stuff you've got stowed away, it will be doing a bang up impression of the Beagle.
Now, if only they could get that stupid NASA sign off of my Caltech/JPL.
