Interstellar Traveler, NASA’s Voyager 1 Probe On 40,000Year Trek to Distant Star

NASA’s news Voyager 1 probe has left the solar system, its next big spaceflight milestone comes with the flyby of another star — in 40,000 years.Voyager 1 has entered interstellar space in August 2012, nearly 35 years after blasting off, scientists announced Thursday (Sept. 12). As it leaves our solar system behind, the robotic spacecraft is streaking toward an encounter with a star called AC +79 3888, which lies 17.6 light-years from Earth.It’s on it’s way home soon how cool is that!We will have so much new information and it is very exciting.”Voyager’s on its way to a close approach with it in about 40,000 years,” Voyager project manager Suzanne Dodd, of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., told reporters Thursday. “It’s going to come within 1.7 light-years of this star — and it’ll swing by it, and it will continue to orbit around the center of our Milky Way galaxy The probe won’t beam home any data from AC +79 3888’s neighborhood, of course. Voyager 1’s declining power supply will force the mission team to turn off its first instrument in 2020, and all of the science gear will stop working by 2025, Dodd said.a dozen years or so to study interstellar space up close, and researchers can’t wait to see what the probe observes in this unexplored realm.on how interstellar plasma flows around the heliosphere Voyager 1 and its twin, Voyager 2, launched a few weeks apart in 1977 to study Jupiter, Saturn, Uranus and Neptune. The duo completed this unprecedented “grand tour” in 1989, and then embarked on a new mission to investigate the outer reaches of the solar system andthe huge bubble of charged particles and magnetic fields that the sun puffs out around itself  said Voyager chief scientist Ed Stone, a physicist at the California Institute of Technology in Pasadena.By Mike Wall, Senior Writer | September 12, 2013 02:01pm ET Originally

Voyager 1, which is zipping along at 38,000 mph (61,000 km/h), is currently 11.7 billion miles (18.8 billion kilometers) from Earth. Voyager 2 took a different route through the solar system and is now 9.5 billion miles (15.3 billion km) from home.Voyager 2 may join its twin in interstellar space three or four years from now, Stone said, stressing that it’s tough to predict a departure date in advance.
