Earth and the Martian moon Phobos dance together in a series of images recently acquired by NASA’s Perseverance Mars rover. Earth appears as a point of light in the Martian sky, disappearing behind the crescent of Phobos, the larger of Mars’ two moons. This is the first time humanity has captured from the surface of

When NASA’s Curiosity rover recently began ascending a Martian valley nicknamed “Big Valley,” it sent back images that were familiar to scientists on the mission: honeycomb textures called polygonal fractures, each about 1.5 to 3 inches (4 to 8 centimeters) wide. The mission has detected small specks of these geometric shapes several times before, but
Written by Lucy Thompson, Senior Research Scientist, University of New Brunswick, Canada Ground planning date: Friday, July 27, 2026 As the APXS uplink leader and strategic planner, I have the privilege of working with the rover engineers most days I am in operations. The APXS instrument measures the chemistry of rocks, unconsolidated materials and the
This view of the outer rim of Jezero Crater’s 150-meter-high rim was taken by the Mastcam-Z instrument aboard NASA’s Perseverance on May 15, 2025, day 1,505, or sol, of the rover’s mission to Mars. The brightly colored rocks exposed along the slope, running from the left center to the right center of the image, belong
NASA’s Perseverance Mars rover has discovered evidence that a 245-foot (75-meter-thick) pile of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. This sequence of layered bedrock, dubbed the “Broom Point Member” by the rover’s science team, is likely more than 3.9 billion years old, making it some of the
