This scary looking robot from outer space is not one of the decepticons, its NASA's repair robot named Dextre. It is designed to repair the International Space Station as a replacement for an astronaut going out in space with its suit and oxygen. Dextre is about twelve feet long that can operate objects smaller than half a fraction of an inch using its eleven foot arms. According to astronaut Richard M. Linnehan, one of the astronauts who geared up Dextre in this operation, it's like "working with a Star Wars prop, but it isn't sci-fi, its reality, and it's happening up here right now." Astronauts can now focus themselves to experiments rather than fixing the ISS.
