Farewell Cassini (trailer)

After almost 20 years in space, the Cassini spacecraft concluded the final chapter of its remarkable story of exploration. The Cassini-Huygens mission probed the spectacular ringed planet — Saturn — taking incredible images of its surface, rings and moons, and spending 13 years in its orbit. Cassini made its "Grand Finale" in 2017, as it plunged into the planet it had studied for so long.

Discover this huge scientific journey, and what it taught us about one of our favourite neighbours, in "Farewell Cassini" — a remarkable tribute by the planetarium filmmaker Theofanis Matsopoulos.
