Video description: For almost 13 years, the spacecraft Cassini has been in the Saturn system, documenting the planet and its moons. Cassini’s days are numbered—on 15 September, it will be sent hurtling towards Saturn. But just because it’s running out of fuel doesn’t mean it’s running out of fire. Cassini has a lot more science to do in its final chapter.
Science shows it’s a small world after all—and nature’s networks follow a similar pattern.
