For NASA JPL engineer Parag Vaze, studying Earth’s rising ocean has been a career three decades in the making.

One of the best ways to understand Earth's ocean is from the perspective of space.

In many communities in the U.S., sea level rise is already a factor in people’s lives in the form of high-tide flooding.

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft. Liftoff was at 10:42 a.m. PST (1:42 p.m. EST).
