NASA Says Farewell to MAVEN Mars Mission, Hosts Media Call Today

The first mission devoted to observing the Martian atmosphere and its evolution, NASA’s MAVEN (Mars Atmosphere and Volatile Evolution), has ended after more than 11 years in orbit at Mars and a decade beyond its primary, one-year mission. The spacecraft was heard last on Dec. 6, when it experienced an unexpected loss of signal after […]

NASA-European Sea Level Mission Homes in on El Niño

Sea level data from a satellite launched by NASA and European partners shows that a swell of warm water hundreds of miles wide has arrived in the Pacific Ocean off the coast of South America, a sign that El Niño will likely emerge later in the year. Because water expands as it warms, a rise […]

NASA-developed AI Could Help Track Harmful Algae

NASA scientists have developed an artificial intelligence tool to take on a longstanding challenge in ocean waters. In a study recently published in AGU Earth and Space Science, researchers reported the tool was able to fuse data from multiple satellites and detect harmful algal blooms that occurred in western Florida and Southern California.
