They launched it 10 years ago.

How on earth (or should that be 'not on earth') did it carry enough fuel?

DS has just made me feel really ancient by pointing out that 10yr old tech may as well have co-existed with dinosaurs.

It may have used gravity to slingshot across other planets along the way.

It has solar panels, I believe.

As space is virtually frictionless, it needs much less fuel than an equivalent motor journey.
