Elon Musk teases he's building a futuristic running track that will let astronauts jog in SPACE

Elon Musk wants to let astronauts run track in space. And the billionaire tech mogul is taking a page from the iconic sci-fi film 2001: A Space Odyssey in order to make it happen. In a tweet on Friday, Musk posted a GIF of David Bowman, the main character of Stanley Kubrick's 1968 film, where he can be seen running around a track in space. Elon Musk tweeted that he would be building a running track on the Big F***ing Rocket (pictured in an artist's impression), similar to the one shown in 2001: A Space Odyssey'Running track in @SpaceX BF Spaceship will look something like this,' Musk wrote in a tweet. The BF spaceship, or as Musk calls it, the Big F***ing Rocket, is a 348ft tall spacecraft that is a key player in his plans to make humans a'multi-planetary species' and one day develop a colony on Mars.
