To give you an idea: Some of the information and pictures taken by flybys and space probes that was received 6, 7, 8 years ago is still being analyzed! Robot ships ("flybys and space probes") are by far the biggest "bang for the buck" of anything NASA has ever spent the money on - they have contributed tremendously to our knowledge of our solar system and our universe. And, they have created a lot of new questions for scientists - which is exactly what's supposed to happen.
