Humanity escapes the solar system: Voyager 1 signals that it has reached the edge of interstellar space
Voyager 1, which has been travelling at the rate of 10km/sec to the outer limits of the solar system since 1977, is now detecting the first traces of 'interstellar winds' (colder and slower than solar winds) - the signs it is finally reaching the edges of solar system. It is now 17,970,000,000 km - or 11,100,000,000 miles away.
Inside the Cupola, NASA astronaut Chris Cassidy, an Expedition 36 flight engineer, uses a 400mm lens on a digital still camera to photograph a target of opportunity on Earth some 250 miles below him and the International Space Station. Cassidy has been aboard the orbital outpost since late March and will continue his stay into September.
