Nasa scientists Sunita Williams and Butch Wilmore Friday said that they are looking forward to cast their ballot in the US election from the International Space Station as their return has been delayed. Answering a question on voting, Wilmore said he sent down his request for a ballot today as it is a very important duty and Nasa makes sure that they are able to cast their votes. Sunita agreed and said she is looking forward to be able to vote from Space.
