Usain Bolt Smokes Astronaut In Zero Gravity Foot Race

He's the fastest man on Earth ... but how would Usain Bolt do in space!??

You're about to find out ...

The Olympic legend boarded a special Airbus Zero G plane, which simulates what it's like to be in zero gravity ... and challenged 2 of his fellow passengers to a foot race.

The challengers? French astronaut Jean-Francois Clervoy (in the blue flight suit) and CEO of Novespace and French Interior designer Octave de Gaulle (in the black).

The guys definitely gave Bolt a run for his money in the first leg of the race, but Usain turned up the heat and crushed 'em when it counted.

And, how'd he celebrate? Usain didn't bust out his signature "Bolt" gesture -- instead, he popped some fancy Mumm Grand Cordon Stellar (fun fact: de Gaulle designed the fancy bottle).

The bottle was reportedly designed for use by future space tourists -- apparently, it's easier to chug from this bottle in zero gravity.

So, if you save up ... a lot ... you can (maybe) test it out one day.

Good luck.
