Discover how NASA astronauts securely cast encrypted votes from the International Space Station using space communication networks, satellite relay systems, and specialized ground telemetry routing.

The ability is based on legislation passed by the Texas Legislature in 1997 that allowed astronauts to vote in elections from space. The first American to vote from orbit was David Wolfe that same year, while aboard the Mir space station.

The process involves specific steps to get a vote from space to the ballot box. First, astronauts apply for a mail-in ballot by completing a federal form. After completing the electronic ballot in the orbiting laboratory, the data is transmitted via NASA’s communications network and relay satellites. The transmission reaches a ground antenna at the White Sands facility in Las Cruces, New Mexico. From there, NASA forwards the ballot to Mission Control at Johnson Space Center and finally to the county clerk who registers the vote.…
