This month, engineers at NASA’s Jet Propulsion Laboratory in Southern California are testing a spacecraft sensor that will help measure how quickly Arctic sea ice is disappearing. And while that instrument won’t launch for another year, scientists started preparing for its use during a recent field campaign in the Canadian wilderness. Researchers spent two weeks […]

Explore how rivers move, change, and sustain life across the planet with SWOT data.

Rivers rise and fall throughout the year, but by how much? Perhaps less than previously thought, according to new data from the SWOT mission. Hidden riverbed contours are also emerging. In a first, a space mission led by NASA and France has tracked Earth’s rivers swelling and shrinking from month to month over the course […]
