I'm impatient. Waiting seven years for test results would drive me bananas. But NASA scientists studying Saturn's rings had no choice but to hold their breath.
For seven years, Cassini has been measuring how fast dust is accumulating on Saturn's rings. The bright rings are gathering dirty dust more slowly than scientists thought, meaning they could be up to 4.4 billion years old. We've still got a lot to learn about the Solar System - but with patience and technology we'll get there!
