Michael Fincke (Expedition 18 commander) and Greg Chamitoff (flight engineer) will beam their vote from the International Space Station as they fly 220 miles (354 km) above Earth.
How they vote from the space?
The County Clerk’s office prepares a secure electronic ballot that is then relayed to the International Space Station via NASA’s Mission Control room at the Johnson Space Center. Meanwhile, the Clerk’s Office sends a separate e-mail to the astronaut with login information to access the ballot and vote.
