Orbital Sciences' Cygnus spacecraft has successfully launched from NASA's Wallops Flight Facility in Virginia on its way to becoming the second private vehicle to resupply the International Space Station.
NASA's two Voyager spacecraft, launched in 1977, have made history in a dramatic fashion by exploring the outer planets: Jupiter, Saturn, Uranus and Neptune. Now one of the vehicles, Voyager I, has made another pioneering leap. It is the first spacecraft to leave the vast bubble of hot gas that surrounds our solar system.
At long last, Voyager 1 is now in interstellar space.
