When NASA astronauts Suni Williams and Butch Wilmore blasted off from Cape Canaveral, Florida, back in June aboard the debut crewed flight of the Boeing Starliner spaceship, there was no reason to believe they’d be out of pocket for the November election.

Boeing's Starliner undocked from the ISS on Friday and is heading back to Earth, without the NASA astronauts it brought to space.

Texas first passed a law in 1997 that allows astronauts to vote if they will be in space during early voting and on Election Day.

American astronauts from NASA will be on the International Space Station (ISS) on 5 November, Election Day, and will cast their votes via postal ballots, CNN reported. They will float 320 kilometres above the nearest polling station that day.
