Voyager 2 Spacecraft Approaches Interstellar Space

When it comes to space exploration, no one has the Voyager missions beat. On October 5, NASA reported that their Voyager 2 spacecraft is nearing our heliosphere’s outer borders, and could soon enter interstellar space. Data shows that the probe is detecting more and more cosmic rays from outer space — indicating a slow escape from the sun’s stellar bubble. If all goes as planned, the craft will follow in the footsteps of Voyager 1 and become the second human-made object to ever visit the interstellar medium.
