An international oceanography satellite that is tracking the ongoing rise in global sea level marks its 10th year in orbit today.

Designed for a three-to-five-year mission, the joint U.S./European Ocean Surface Topography Mission (OSTM) on the Jason-2 satellite has now made more than 47,000 trips around our home planet, measuring sea level change across the globe, observing ocean currents, studying climate phenomena such as El Nino and La Nina, and monitoring the long-term rise in global mean sea level. In January 2016, it was joined in orbit by its follow-on mission, Jason-3. NASA's Jet Propulsion Laboratory in Pasadena, California, manages NASA's portion of both missions.
