Ребята, давай в космонавты!  After almost 20 years in space, NASA's Cassini spacecraft has begun the final chapter of its remarkable story of exploration: its Grand Finale. This last phase of the mission will deliver unprecedented views of Saturn and its rings when, on April 26, the spacecraft dives between the planet and its rings – a feat that has never been attempted. Cassini will complete 22 of these ring-gap orbits before making a grand finale dive into Saturn’s atmosphere to protect the environments of Saturn’s moons, including the potentially habitable Enceladus. Ребята, давай в космонавты!
