Early in its history Mars may have had a thin layer of icy clouds creating a greenhouse effect that kept conditions warm enough for water to flow, study finds. As seen in images shared by NASAs Perseverance rover, Mars is a dust covered desert planet with no clear signs of life, but the SUV-sized vehicle is currently exploring an area that was once a river delta, formed by flowing water.    At a time when Mars had rivers and lakes the sun was weaker than it is today, with the Red Planet rece...

Every morning during the warmer months in the southern part of the Red Planet, an exceptionally long cloud appears over a Martian volcano. The cloud of water ice, which appears close to the Arsia Mons volcano, stretches out over a thousand kilometers before dissipating within hours of forming. Oddly enough, the Arsia Mons is the only volcano in that area that possesses such an unusual cloud on a daily basis. And now, based on observations conducted by the Visual Monitoring Camera (also known as...

Mars Express and the case of the large, mysterious Martian volcano cloud April 21, 2021 Throughout the southern Martian hemisphere’s spring and summer seasons, a large, expansive cloud emerges daily from the volcano Arsia Mons.  Why this cloud only forms at this location on Mars, what kind of cloud it is, and other puzzles to this phenomenon have plagued researchers for years — as observing Martian weather usually only happens by accident during other investigations. Now, a team of researc...

What happened to Marss water? New study suggests most was trapped in underground rocks Posted TueTuesday 16 updated WedWednesday 17 MarMarch 2021 at 2:35am The early Martian environment (right), believed to contain liquid water and a thicker atmosphere, is a world away from the cold, dry environment of Mars today (left).

What if most of Mars' water never actually drifted into space?

Mars Express helps researchers solve a Martian mystery that happens each spring Shane McGlaun - Mar 15, 2021, 7:18am CDT Each year when spring arrives in southern Mars, a strange cloud of water ice emerges near the extremely tall Arsia Mons volcano. The cloud stretches for hundreds of kilometers before it fades away over hours. Researchers have been performing a detailed long-term study of the phenomena and has discovered the secret of the elongated cloud using observations f...

We Finally Know Whats Going on With That Weird, Long, Recurring Cloud on Mars 12 MARCH 2021 In 2018, a camera on board the Mars Express mission caught sight of a strangely long and wispy cloud, billowing across the surface of the red planet. From a distance, the 1,500-kilometer (930-mile) trail of fog almost resembled a plume of smoke, and it seemed to be emerging from the top of a long-dead volcano.   Looking back at archived images, researchers soon realized this had been happening for a ...

Scientists unravel mystery of 1,100-mile-long cloud forming above Martian volcanoes Its similar to how these clouds form on Earth only on a massive scale. The cloud is about 1,118 miles (1,800 kilometers) long and 93 miles (150 km) across. Credit: ESA. Every year around Mars’ southern solstice, a strange elongated ice cloud forms over the red planet’s surface. The exact nature of this peculiar meteorological phenomenon has been elusive — until recently. Scientists affiliated with the E...
