NASA astronaut Kate Rubins posted a photo of her voting from the 'ISS voting booth' in space

• NASA astronaut Kate Rubins tweeted a photo of her voting from the International Space Station.
• Most astronauts live in Texas, and the state allows them to use a secure electronic ballot to vote from space.

NASA astronaut Kate Rubins, like many Americans this year, cast her ballot and followed it up with a photo for social media.

Rubins is spending six months on the International Space Station, where she voted from on Friday.

A photo of the moment, which the NASA Astronauts Twitter shared, shows Rubins in front of a handwritten sign that says "ISS voting booth."

Rubins told The Associated Press last month that astronauts cast votes from the orbit because they "feel that it's very important."

"It's critical to participate in our democracy," she said. "We consider it an honor to be able to vote from space, and so we fill out a form and we vote via absentee ballot, and I plan on doing that in November."

Most American astronauts live in Houston, Texas, and state law allows them to use a secure electronic ballot to cast a vote, the AP reported. Mission Control then sends the ballot to the county clerk.

"I think it's really important for everybody to vote, and if we can do it from space, then I believe folks can do it from the ground too," Rubins said.
