Craft reaches, perhaps passes, solar system edge

Voyager 1 is 'beginning the exploration of a new frontier,' said Voyager project scientist Edward Stone, of NASA's Jet Propulsion Laboratory.

Voyager 1, which was launched from Cape Canaveral on September 5, 1977, has now possibly reached the heliopause, the region at the edge of our solarsystem where the solar wind is stopped by the interstellar medium. The instrument that could tell the scientists definately whether it has reached that point broke down years ago, so they are relying on other measurements to try to establish the amount of solar wind and temperature.
