While we haven’t colonized the moon (yet), you could vote from outer space today. Yep, the NASA astronauts aboard the International Space Station have the option of voting via an electronic ballot, beamed up by Mission Control in Houston. Astronauts fill out the ballot and beam it back down to Mission Control, where it is sent directly to the proper authorities. In 1997, that made the process possible. In 2004, Leroy Chiao became the first American to vote from space. Two Americans are part of the current ISS expedition, but both of them filled out ballots—while stationed in Russia—before leaving the planet.
