Leonard Nimoy, famous for his role as Spock — the infallibly logical character in the Star Trek TV series and movies — died on February 27, and astronaut Terry Virts gave the beloved actor the perfect send off. Virts has been living on board the International Space Station since September, 2014 and he snapped a photo of himself giving a Vulcan salute when the ISS passed over Boston — the city in which Nimoy was born.
