Sunita Williams, other astronauts post US poll day pic from space

Astronauts Butch Wilmore, Sunita Williams, and Don Pettit shared a patriotic photo from space on US election day, sporting red, white, and blue socks. Two pairs displayed the message "Proud to be American." The astronauts had cast their early presidential ballots from the International Space Station, with NASA's Near Space Network securely transmitting their votes back to Earth.
