There have been many incredible planetary missions over the past several decades, from as close as our Moon to the outer reaches of the Solar System. Right now, there are robotic explorers at Mars, Jupiter, Saturn, Ceres, and out past Pluto. But there are two more which have travelled even farther, to the most distant fringes of the Solar System, Voyager 1 and Voyager 2. Although they were launched way back in 1977, they are still active today, studying the region where our planetary system “ends” and interstellar space begins. Now, the Hubble Space Telescope is being used to help provide a “road map” for their future paths forward.
