A NASA spacecraft marked a big milestone on June 30 — a decade exploring Saturn and its many moons. Cassini probe has made a number of unprecedented observations and discoveries. Although the spacecraft was originally approved for a four-year mission, it has been granted three mission extensions, allowing it to continue roaming the gas giant’s system. Cassini has helped scientists learn more about what kinds of molecules populate our solar system. The spacecraft discovered plumes containing water-ice shooting out into space from the south polar region of Saturn’s moon Enceladus.
