GO VOTE. Even astronauts aboard the ISS do it.

For those of you in the U.S., here's a friendly reminder to get out and vote today. And if, for some reason, you feel like your polling place is a little too far to make the trip, just remember that even astronauts aboard the International Space Station find a way to vote on election day — and not just by voting early, either.

SPACE.com's Mike Wall explains:

Call it the ultimate absentee ballot. NASA astronauts aboard the International Space Station have the option of voting in [today's] presidential election from orbit, hundreds of miles above their nearest polling location.

Astronauts residing on the orbiting lab receive a digital version of their ballot, which is beamed up by Mission Control at the agency's Johnson Space Center (JSC) in Houston. Filled-out ballots find their way back down to Earth along the same path.

"They send it back to Mission Control," said NASA spokesman Jay Bolden of JSC. "It's a secure ballot that is then sent directly to the voting authorities."

So go vote. Suffering from last minute indecision? If you care about such things (and if you're reading this, chances are you do), do yourself a favor and read Obama and Romney's answers to the country's top science questions.
