i totally concur.....amazing exploration and science, plus? as far as i can discern a significant leap forward in man's ability to travel. i am having some difficulty finding out the maximum velocity the craft achieved or will achieve e.g. to calculate the hypothetical travel time to Proxima Centuri.

comet 67P G-C is travelling at as much as 135,000 km/h (from ESA www) = 375 km/sec = approximately 0.125% of speed of light, and Rosetta space craft is now orbiting it. As Rosetta approached 67P it did a series of burns to slow down to the comet's speed.

other space craft such as New Horizons, Voyager 1 and 2 seemed to all travel at about 16 km/sec and i was starting to wonder what was special about that speed?

is it correct to deduce there has just been a 20+ fold increase in our effective travel velocity/speed?
