On this day in space, Aug. 17, 1877: American astronomer Asaph Hall discovered Mars’s moon Phobos.
Scientists found a Martian meteorite on Earth that is finally filling in a nearly 2-billion-year-old geology-history gap on the Red Planet.
These tiny capes carry some serious technology.
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 […]
NASA’s Curiosity Mars rover spotted surprising honeycomb-like shapes in the Red Planet soil while exploring a large valley.
Mars dust is known to contain various carcinogens, such as silica and numerous heavy metals. How will future astronauts mitigate the health risks?
A new analysis of decades-old data from NASA’s Spirit rover has uncovered overlooked traces of crystalline hematite and altered magnetite, adding to growing evidence that liquid water once played a major role in shaping the Red Planet.
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. The mission has spotted small patches of these geometric shapes several times […]
