Two probes, continuing science
Huygens landed and Deep Impact crashed, but scientists are still learning from both events.

Huygens' quiet landing on Saturn's moon Titan and Deep Impact's spectacular smash-up achieved their respective goals. But once the cheering ended, the hard work of analyzing the probes' data began — and it continues today.
