The Voyager 1 spacecraft is moving through the very outer boundary of our solar system, and moving into interstellar space. Launched in 1977, Voyager 1 accomplished its initial goals of exploring the gas giants Jupiter and Saturn, and is continuing to send back interesting data. NPR's Melissa Block talks to astrophysicist Neil deGrasse Tyson of the Hayden Planetarium about the spacecraft and the outer limits of our sun's influence.
