A new man-made speed record has been set.
It staggers the mind to think about a man-made machine traveling this fast.

Hadn't heard about this one. That's cooking.
yeah but what kind of gas millage does it get?

Well, if you look up the fuel load of an Atlas V (kerosene plus oxygen), the weight per gallon of the fuel, and the average distance from Earth to Jupiter, you can make a reasonable guess. I get a figure of approximately 5400 miles per gallon. Of course, the probe isn't going in a straight line due the the slingshot maneuver and orbital mechanics. So it's actually much greater than that.
You're welcome

At least it's going somewhere.
The shuttle travels at a very impressive 5 miles per second, and has not traveled more than 165 miles away from earth. Check that fuel economy.

Galaxies? Andromeda is the nearest, 2.5 million light years away. That's 2.5 million years at 100% of the speed of light, 1/4 of a billion years at 1%.

That 2,500,000 years to Andromeda at 100% of c only applies if your're standing here on Earth.
If you're the one in motion, at 100% of c time stops, so you're there in no time!

But that brings up another problem with really fast travel - stopping once you get there. I guess if you spent a couple hundred million years in transit, then a few hundred thousand years of braking into orbit around a star to slow down won't be too bad.
It's probably still fast enough, that they need to start re-tuning radio frequency reception and transmission frequencies for it, to account for Doppler effects, and adjust time stamps for Einsteinian relativistic effects...

Oh boy! If I go faster than the speed of light, does that mean that I can catch up with the episode of the Kardashians that I missed? I can't wait!
Ok, the truth is that I missed them all -- but I'm just excited to think that it might be possible!
