U.S. astronauts aboard the International Space Station (ISS) have successfully cast their ballots in the 2024 elections using NASA's Space Communication and Navigation (SCaN) network. Despite being 250 miles above Earth, they can securely transmit their votes back home. NASA's Tracking and Data Relay Satellite System enables the encrypted transmission of electronic ballots to ground stations, where they are then sent to county clerks for processing. Astronauts, including Nick Hague, Don Pettit, Butch Wilmore, and Sunita Williams, emphasized the importance of voting, with Wilmore highlighting NASA's support in facilitating this crucial civic duty. Voting from space has a history dating back to 1997 when Texas legalized it, making it possible for astronauts to participate in elections remotely. SCaN’s capabilities also play vital roles in various NASA missions, including maintaining communication lines for deep space exploration as well as connecting astronauts to their families and mission control. As NASA continues to enhance its communication technology, they ensure that regardless of their location, astronauts can exercise their right to vote in U.S. elections.
