There might be a hidden ocean’s worth of liquid water below the surface of Mars, seismic evidence suggests. According to a new paper published April 25 in the journal National Science Review, recordings of seismic waves from deep within the Red Planet indicate that a layer of liquid water may be lurking in the Martian … Read more
NASA’s Curiosity rover has found some of the best evidence yet that ancient life may have existed on Mars — and an answer for what could have wiped it out. When drilling into rocks on Mount Sharp, the central peak of the Red Planet’s Gale Crater, the rover found evidence of siderite, an iron carbonate … Read more
We may have been wrong about how Mars got its characteristic red hue, a new study reveals. The Red Planet owes its ruddy complexion to rusted iron minerals, dispersed across billions of years by winds, throughout the planet’s dust. Past spacecraft observations of Martian dust led scientists to believe that this rust emerged in dry … Read more
Scientists have discovered evidence that liquid water was once exposed to the air in ancient, shallow lakes on Mars. The finding is evidence that not all water on the Red Planet was covered in ice, as some Martian climate models suggest. Planetary geologists and astronomers studying Mars have known for decades that water was once … Read more
Monstrous dust storms often ravage Mars, engulfing the Red Planet for months. Now, a new study suggests these global storms may be related to a peculiar energy imbalance recently discovered across the Martian surface. The solar system’s planets and moons absorb energy from the sun, but they also emit energy back into space. The difference … Read more
Tiny photosynthetic microbes could be secretly thriving on Mars — hiding inside small bubbles of liquid water in the thin layers of dusty ice that litter the Red Planet’s surface, a new NASA-led study reveals. Researchers believe the icy patches could be among the most promising targets in the hunt for extraterrestrial life within our … Read more
Have you ever wondered what it would be like to spend a night on Mars? This excerpt from the new book “Daydreaming in the Solar System” by John E. Moores and Jesse Rogerson, takes a poetic look at what it might be like to explore the Red Planet if you were faced with the daunting … Read more
Believe it or not, debris from Mars has frequently made its way to Earth after powerful impacts hit the Red Planet’s surface and launch it into space. There have been at least 10 of these meteorite-forming events in Mars’ recent history. When these massive impacts occur, meteorites can be flung away from the Red Planet … Read more
Mars is a planet of vast contrasts — huge volcanoes, deep canyons, and craters that may or may not host running water. It will be an amazing location for future tourists to explore, once we put the first Red Planet colonies into motion. The landing sites for these future missions will likely need to be … Read more
A satellite orbiting Mars has captured the best-ever images of a gigantic “scar” carved across the Red Planet’s surface. The dark ravine, which is accompanied by unusual zebra-like stripes, is likely the result of extreme volcanic activity millions of years ago. The striking surface feature, named Aganippe Fossa, is a graben — a “ditch-like groove … Read more
