Yesterday, the biggest interplanetary spacecraft NASA has ever built self-destructed. Cassini made a suicidal dive into Saturn’s stratosphere and brought to an explosive finale two decades in space.

The probe had run out of the propellants that got it to Saturn, and by crash-landing it, scientists have preserved Saturn’s pristine moons for
later exploration.

This film uses incredible photographs the probe has captured to tell the story of Cassini, which has given scientists amazing insights into Saturn and the potential of its moons to sustain life. A Horizon special airs on BBC2 on Monday (times vary).
