This spacecraft was not originally planned to stay in orbit as long as it did. “The Grand Finale, as it was called, was set in motion in April 2017, when Cassini was put on an impact course with Saturn through a series of 22 orbits between the planet and its rings. The never-before explored areas provided researchers with additional information that was too risky to obtain earlier in the mission. This included detailed maps of Saturn’s gravity and magnetic fields, which will enable scientists to calculate its rotation speed,”(second
