Slope streaks on Mars hint at possibility of more water than previously believed


Streaks seen on slopes in Mars along its equatorial region have prompted scientists to believe that there has been more water activity on the planet than once believed.If this is the case, then the chances of finding life in some form in the vicinity of these streaks are considered high.The …

What could explain the mystery of how land formed on Mars without much water

The surface of Mars, with its dune flows, gullies and slope movements, is the result of sediment being transported downwards in the recent past as well as today. But this “mass wasting”, typically caused by flows of water – for example, how the gullies on Earth are shaped – has …

Boiling Water May Cause Sands To Levitate On Planet Mars : SCIENCE : Tech Times

Boiling water under low pressure causes sand and sediments on the surface of Mars to levitate. What are the factors that cause liquid water on the Red Planet to boil?  ( Alexander Antropov ) A newly discovered process may help explain a debated mystery on how land features on Mars …

Sand ‘levitating’ on boiling water shapes landscapes on Mars

This means that, in comparison to the Earth, relatively small amounts of liquid water moving across Mars’ surface could form the large dune flows, gullies and other features, which characterise the red planet. (Reuters) Small amounts of boiling water causes sand on Mars to ‘levitate’ and move around, according to …

Hydrothermal deposits hint at once habitable Mars

Ocean McIntyre October 21st, 2017 This view of a portion of the Eridania region of Mars shows blocks of deep-basin deposits that have been surrounded and partially buried by younger volcanic deposits. (Click for full view) Image & Caption Credit: NASA/JPL-Caltech/MSSS A recent report in Nature Communications indicates that ancient …

It seems more likely than ever that Mars once had both liquid water and surface ice

Thanks to decades of exploration using robotic orbiter missions, landers and rovers, scientists are certain that billions of years ago, liquid water flowed on the surface of Mars. Beyond that, many questions have remained, which include whether or not the waterflow was intermittent or regular. In other words, was Mars …

Flowing water could have carved valleys on ‘icy’ ancient Mars

New research may bridge the gap between two ideas about the climate of ancient Mars—the “warm and wet” story of Martian geology and the “cold and icy” past of atmospheric models. Scientists have long tried to understand what ancient Mars might have been like, but the red planet has offered …

Soil as a carbon sink can hold more than previously believed – Red & Black Student Newspaper

We have known for quite sometime how Earth i.e. soil acts as a major carbon sink with researchers suggested that there is a limit to the amount of carbon soil can hold; however, a new study has shown that soil is a much larger carbon sink than previously believed. A …
