For NASA engineer Shannon Statham, building spacecraft is all about being creative.

Experts from NASA, ESA, EUMETSAT, and NOAA discuss the upcoming launch of Sentinel-6 Michael Freilich in a recorded live broadcast

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).

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.

Mission team members perform acoustic tests of the Sentinel-6 Michael Freilich satellite in a chamber outfitted with giant speakers that blast the spacecraft with sound. This is to ensure that the ...

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.
