Martian ice deposits could sustain human outposts in the future

Martian ice deposits could sustain human outposts in the future”

At this wedge-shaped pit on Mars, the steep slope (or scarp) at the northern edge (toward the top of the image) exposes a cross-section of a thick sheet of underground water ice.

In 2001, the Mars Odyssey spacecraft discovered, through the detection of hydrogen using gamma rays, that a third of Mars' surface is covered in shallow ice and its poles are full of ice deposits.

Finding water or ice on Mars is becoming fairly commonplace these days, but this is a new one: researchers are reporting that they've spotted tall cliffs, up to 100 metres (328 feet) high, made of almost pure water ice in several locations on Mars!

The ice sheets which appeared bluish in the high-resolution images, looked like steep cliffs of glaciers, up to 100 meters tall.

"The ice is concentrated in layered deposits at the poles, and also found in the shallow sub-surface at middle latitudes, as in our study".

"We've found a new window into the ice for study, which we hope will be of interest to those interested in all aspects of ice on Mars and its history, " The Washington Post reported quoting Colin Dundas, a member of the US Geological Survey's Astrogeology Science Center in Arizona and an author of a report published Thursday in the journal Science. The discovery points to a vast area of underground ice buried only a meter or two below Martian ground surface.

The latitudes were the equivalent on Earth of Scotland or the tip of South America.

"It's like having one of those ant farms where you can see through the glass on the side to learn about what's usually hidden beneath the ground", the paper's co-author Shane Byrne said in a statement.

No definitive information was provided on how the scarps were formed.

"Our interpretation is that this is consolidated snow deposited in geologically recent times", Dundas said.

The varying shades of light to dark blue color of ice as shown on the images, suggest that the thick slabs of ice are stacked.

The discovery is considered a game changer in mankind's exploration of Mars.

The frozen water near the Martian surface was detected using images from NASA spacecraft Mars Reconnaissance Orbiter now orbiting Mars.

The authors of the study have said that the latest discovery will be helpful for the establishment of a base on the Red Planet, as the water could be used for drinking, potentially create oxygen and fuel. This makes these sites very valuable, for the climate science they contain locked away in their layers, and as a potential water source for when humans eventually land on Mars, and attempt to establish colonies there.
