Equipped with rock picks and hand lenses, a team of geoscientists deployed to the Mojave Desert recently to investigate a tantalizing “fingerprint” detected by a NASA sensor. Their target: a cache of topaz hiding in plain sight. The geologists weren’t searching for gem-grade treasure. Rather, the presence of topaz could hint at a more valuable […]
A compact, multifrequency radar built by a team at NASA’s Jet Propulsion Laboratory will make it easier to collect information about dynamic cloud systems. Called CloudCube, this new instrument simultaneously probes the atmosphere with three radar signals, spanning 36 to 240 GHz, for optimized sensitivity to a wide range of water droplet and ice particle sizes.
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 […]
Radar data from an agricultural area in South Africa, shown in a vivid color palette, reveal crop types and how they changed during the Southern Hemisphere’s growing season.
Scientists analyzed 20 Martian samples collected by NASA’s Curiosity Rover and found that differences in hematite crystallite size at varying elevations could serve as a new mineralogical marker for understanding Mars’ ancient climate.
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 announced plans Friday to compete the next contract for managing and operating the agency’s federally funded research and development center (FFRDC) in Southern California at the Jet Propulsion Laboratory (JPL), to ensure continued accountability and strong value for U.S. taxpayers. The California Institute of Technology (Caltech) has managed the laboratory since its inception in […]
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. Severe blooms […]
NASA’s Psyche spacecraft completed its close approach of Mars on May 15, coming within 2,864 miles (4,609 kilometers) of the planet’s surface. This flyby used a gravity assist from Mars to provide a critical boost in speed and to adjust the spacecraft’s orbital plane without using any onboard propellant, sending it on its way toward […]
NASA’s Perseverance Mars rover recently took a self-portrait against a sweeping backdrop of ancient Martian terrain at a location the science team calls “Lac de Charmes.” Assembled from 61 individual images, the selfie shows Perseverance training its mast on a rocky outcrop on which it had just made a circular abrasion patch, with the western […]
