Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
on March 15, 2023 at 5:24 pm
Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
The planet that could end life on Earth
on March 7, 2023 at 12:31 pm
A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.
Better tools needed to determine ancient life on Mars
on February 21, 2023 at 6:21 pm
Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to new research.
Study quantifies global impact of electricity in dust storms on Mars
on February 16, 2023 at 9:12 pm
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 can become electrified. New research shows that one particularly efficient way to move chlorine from the ground to the air on Mars is by way of reactions set off by electrical discharge generated in dust activities.
Spanish lagoon used to better understand wet-to-dry transition of Mars
on February 8, 2023 at 5:51 pm
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 years.
Researchers complete first real-world study of Martian helicopter dust dynamics
on January 31, 2023 at 3:18 pm
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 rotorcraft missions. The work could support NASA's Mars Sample Return Program, which will retrieve samples collected by Perseverance, or the Dragonfly mission that will set course for Titan, Saturn's largest moon, in 2027.
The rich meteorology of Mars studied in detail from the Perseverance rover
on January 18, 2023 at 4:17 pm
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 daily cycles of temperature and pressure, as well as their significant variations on other time scales resulting from very different processes.
Martian meteorite contains large diversity of organic compounds
on January 12, 2023 at 4:31 pm
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 history.
Experimentalists: Sorry, no oxygen required to make these minerals on Mars
on December 22, 2022 at 5:28 pm
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 more oxygen in its atmosphere billions of years ago. But a new experimental study upends this view. Scientists discovered that under Mars-like conditions, manganese oxides can be readily formed without atmospheric oxygen.

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 previously recorded quake on Mars. Mapping the seismic activity on Mars will help inform scientists where and how to build structures to ensure the safety of future human explorers.
Sound recording made of dust devils (tiny tornadoes of dust, grit) on Mars
on December 13, 2022 at 5:14 pm
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 extraterrestrial whirlwind.
Tiny underwater sand dunes may shed light on larger terrestrial and Martian formations
on December 6, 2022 at 4:57 pm
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 Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.
Giant mantle plume reveals Mars is more active than previously thought
on December 5, 2022 at 5:15 pm
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 and Venus, possesses an active interior, which challenges current views on the evolution of the red planet.
Mars was once covered by 300-meter deep oceans, study shows
on November 17, 2022 at 3:28 pm
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 the first life in our solar system may have been on Mars.
Exploring the possibility of extraterrestrial life living in caves
on November 16, 2022 at 2:00 pm
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 subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.
NASA's MAVEN observes Martian light show caused by major solar storm
on November 10, 2022 at 4:43 pm
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. 27.
Earth's oldest stromatolites and the search for life on Mars
on November 7, 2022 at 6:58 pm
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 been subjected to advanced alteration and metamorphism. Stromatolites, layered organo-sedimentary structures reflecting complex interplays between microbial communities and their environment, have long been considered key macrofossils for life detection in ancient sedimentary rocks; however, the biological origin of ancient stromatolites has frequently been criticized.
