Voyager 2 Probe <br />Enters Interstellar Space Scientists say the NASA <br />probe crossed out of the <br />heliosphere into interstellar <br />space on November 5. The heliosphere is <br />described as a plasma bubble <br />that is created by the sun. Suzanne Dodd, Voyager Project Manager, via Endgadget Launched in 1977, <br />Voyager 2 is now 11 <br />billion miles from earth. On board the probe <br />is a Plasma Science Experiment. The instrument is designed to <br />take measurements of solar wind. Voyager 2 is still <br />considered to be <br />in the solar system. Scientists estimate it will <br />take the craft 30,000 <br />years to exit the outer edge.
