The lone American astronaut who won't be able to make it to the polls Tuesday is keeping with NASA's motto of "Vote while you float."
On Monday, NASA said astronaut Shane Kimbrough cast his ballot from the International Space Station.
Before launching into space, Kimbrough said it would be cool to be able to say "I voted from space."
NASA also noted that Kate Rubins, who was previously at the space station, cast an absentee ballot from out of this world before returning to Earth.
According to NASA, a Texas law from 1997 allows astronauts to vote from space. NASA said nearly all their astronauts live in Houston, Texas, so they have the ability to vote from space.
The voting process, however, begins a year before launch for NASA's astronauts. That's because they have to decide which elections they wish to vote in.
Six months before the elections, astronauts are given a "Voter Registration and Absentee Ballot Request - Federal Post Card Application.”
NASA astronaut David Wolf was the first American to vote in space.
