Perseverance Captures Another Phobos TransitDescription NASA’s Perseverance Mars rover used its Mastcam-Z camera to capture the silhouette of Phobos, one of the two Martian moons, as it crossed in front of the Sun on Aug. 12, 2026, the 1,948th Martian day, or sol, of the mission. The animation has been tinted to simulate what a human would see if […]
Starstruck: NASA Research Shows How Sun’s Ancient History Shaped EarthAt the center of our solar system, the Sun influences every planet that orbits it. In two recent NASA-funded studies, scientists uncovered how ancient events in the Sun’s history may have helped create Earth’s unique climate and driven previously unexplained climatic shifts. In new research, scientists at NASA’s SHIELD (Solar Wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) center — one of […]

MAIA Air Sensor at Work in Addis AbabaDescription This roof-mounted air sensor in Addis Ababa, the capital of Ethiopia, is one of 10 used by NASA’s Multi-Angle Imager for Aerosols (MAIA) to study the city’s air quality. MAIA’s air sensors provide a detailed look at particulate matter that is 2.5 micrometers or less in diameter, also known as PM2.5, one of the world’s deadliest forms […]
Mapping Air Pollution With MAIA Sensors in Addis AbabaDescription This map of Addis Ababa, the capital of Ethiopia, shows the locations of 10 air sensors that NASA’s Multi-Angle Imager for Aerosols (MAIA) mission is using to provide one of the most detailed looks ever at the city’s air pollution. Over the course of three years, these sensors measured particulate matter that is 2.5 micrometers or less […]
What Lake Bonneville Left BehindThe drying of the massive lake exposed playas that became the setting for feats of engineering and technological ingenuity, as well as epic tales of exploration and desperation.
Curiosity Blog, Sols 4982–4987: Back to Our Regularly Scheduled ProgrammingBy Allison Dries-Padilla, Missions Operations Specialist at Malin Space Science Systems Earth planning date: Friday, Aug. 14, 2026 This week of Curiosity Mars rover operations takes us back to our “regularly scheduled programming.” After taking a slight detour to investigate the “erosional surface” we are back on course to ascend Mount Sharp. As we transition […]

NASA Shares Views of August Solar Eclipse from Ground, Air, SpaceOn Aug. 12, a total solar eclipse darkened skies over Greenland, Iceland, and Spain. As the Moon covered the Sun, it briefly revealed the Sun’s wispy outer atmosphere — the corona — to those in the path of totality who were lucky enough to have clear skies. NASA researchers and photographers were along the eclipse […]
