NASA’s newest astrophysics space telescope launched in March on a mission to create an all-sky map of the universe. Now settled into low-Earth orbit, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) has begun…

The Mars Reconnaissance Orbiter is testing a series of large spacecraft rolls that will help it hunt for water. After nearly 20 years of operations, NASA’s Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze…

During his work on several historic missions, Casani rose through a series of technical and management positions, making an indelible mark on the nation’s space program.   John R. Casani, a visionary engineer who served a central role in many…

In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface. On June 3, NASA’s Perseverance Mars rover ground down a portion…

The rover recently drilled a sample from a new region with features that could reveal whether Mars’ subsurface once provided an environment suitable for life. New images from NASA’s Curiosity Mars rover show the first close-up views of a region…

The 2001 Odyssey spacecraft captured a first-of-its-kind look at Arsia Mons, which dwarfs Earth’s tallest volcanoes. A new panorama from NASA’s 2001 Mars Odyssey orbiter shows one of the Red Planet’s biggest volcanoes, Arsia Mons, poking through a canopy of…

Editor’s note: The caption for the OPERA portal image of uplift in the Gulf of California was updated on June 25, 2025. An online tool maps measurements and enables non-experts to understand earthquakes, subsidence, landslides, and other types of land motion.…

Black holes are invisible to us unless they interact with something else. Some continuously eat gas and dust, and appear to glow brightly over time as matter falls in. But other black holes secretly lie in wait for years until…

In a first, researchers from NASA and Virginia Tech used satellite data to measure the height and speed of potentially hazardous flood waves traveling down U.S. rivers. The three waves they tracked were likely caused by extreme rainfall and by…

The rover took the image — its fifth since landing in February 2021 — between stops investigating the Martian surface. A Martian dust devil photobombed NASA’s Perseverance Mars rover as it took a selfie on May 10 to mark its…
