Feb. 16, 2023 — Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth. When dust particles rub against each other, as they do in Martian dust storms, they ...
Feb. 8, 2023 — In the ongoing search for signs of life on Mars, a new study proposes focusing on 'time-resolved analogs' -- dynamic and similar Earth environments where changes can be analyzed over many ...
Jan. 31, 2023 — Researchers have completed the first real-world study of Martian dust dynamics based on Ingenuity's historic first flights on the Red Planet, paving the way for future extraterrestrial ...
Jan. 18, 2023 — Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and ...
Jan. 12, 2023 — Unraveling the origin stories of the Tissint meteorite's organic compounds can help scientists understand whether the Red Planet ever hosted life, as well as Earth's geologic ...
Dec. 22, 2022 — When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had ...
Dec. 15, 2022 — The quake lasted four hours and identified layering in the crust that could indicate a meteoroid impact. The 4.7 magnitude temblor happened in May 2022 and released five times more energy than any ...
Dec. 13, 2022 — When the rover Perseverance landed on Mars, it was equipped with the first working microphone on the planet's surface. Scientists have used it to make the first-ever audio recording of an ...
Dec. 6, 2022 — Researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on ...
Dec. 5, 2022 — Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. The discovery reveals that Mars, like Earth ...
Nov. 17, 2022 — When Mars was a young planet, it was bombarded by icy asteroids that delivered water and organic chemistry necessary for life to emerge. According to the professor behind a new study, this means that ...
Nov. 16, 2022 — For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these ...
Nov. 10, 2022 — For the first time in its eight years orbiting Mars, NASA's MAVEN mission witnessed two different types of ultraviolet aurorae simultaneously, the result of solar storms that began on Aug. ...
Nov. 7, 2022 — The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often ...
Nov. 4, 2022 — A new study finds the original crust on Mars is more complex, and evolved, than previously thought. Researchers have determined the Martian crust has greater concentrations of the chemical element ...
Oct. 28, 2022 — Seismologists have developed a new method to scan the deep interior of planets in our solar system to confirm whether they have a core at the heart of their ...
Oct. 27, 2022 — NASA's InSight lander recorded a magnitude 4 marsquake last Dec. 24, but scientists learned only later the cause of that quake: a meteoroid strike estimated to be one of the biggest seen on Mars ...
Oct. 27, 2022 — Until now, Mars has been generally considered a geologically dead planet. An international team of researchers now reports that seismic signals indicate vulcanism still plays an active role in ...
Oct. 27, 2022 — A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise ...
Oct. 25, 2022 — Scientists found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed. So, if life did, in fact, evolve when the last waters flowed on Mars, it would ...
