When a rose-colored meteorite was found in the Sahara Desert in 2022, no one knew how old it was or where it came from. Not until NASA-funded scientists age-dated its minerals did they realize the nearly 2-pound (800-gram) rock was a piece of Mars that formed more than 4.1 billion years ago, making it one […]

Over 1,645 Martian days, NASA’s Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including some that are small enough to penetrate the lungs and enter the bloodstream. The findings will be published Tuesday, Oct.

When NASA’s Perseverance rover reached the inner edge of Mars’ Jezero Crater in September 2023, mission scientists were surprised by what they found. Called the “Margin Unit,” the geologic area stretches along the shoreline of an ancient Martian lake, so they expected sedimentary rocks, which would have formed as layers of sand piled on top […]

Planning crewed missions to the Moon and Mars involves preparing for the medical realities of long-duration space travel. Factors like cosmic radiation, microgravity, and distance from Earth create unique health considerations for astronauts. To anticipate these needs ahead of time, NASA developed the Integrated Medical Model (IMM).

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 […]

As NASA’s Curiosity rover recently began climbing up a Martian valley nicknamed “Valle Grande,” it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each one about 1.5 to 3 inches (4 to 8 centimeters) across.
