This American astronaut just voted from space. Here's how she did it - CNN

NASA's Johnson Space Center is located in Houston, so most astronauts are based in the city and registered to vote in Harris County, where Houston is located.

The space-voting process works like this, NASA told CNN last month: The Harris County Clerk's Office uploads a secure electronic ballot to NASA's Johnson Space Center Mission Control Center.

NASA astronauts, using specific credentials, access their ballot and cast their vote, which is delivered back to the county clerk's office by email.
