NASA astronaut Anil Menon has cast his ballot in the U.S. midterm elections from the International Space Station, using an electronic voting system. In a video released on Tuesday, Menon showed how he completed his ballot on a computer aboard the station and sent it to election officials in Harris County, Texas. He said all three U.S. crew members aboard the space station had the opportunity to vote. Americans went to the polls on Tuesday in midterm elections that will determine control of Congress and serve as a test of President Donald Trump’s second-term leadership.
