Launch was just the beginning
The successful launch of the Jason-3 satellite on January 17 was a major accomplishment for the Jason mission, but it is by no means the end of the road. On the contrary, much of the hard work has just begun.
Satellite instruments and the data they provide are incredibly precise. Once operational, the Jason-3 satellite will be able to detect changes in sea level height down to the millimeter. This requires a careful fine-tuning of the instruments from here on Earth.
