Scientists spot massive ice deposits on Mars

Recent observations by MRO's ground-penetrating Shallow Radar instrument revealed a buried ice layer that covers more ground than the state of New Mexico.

  • Recently, scientists have found layers of ice on the Martian land.
  • Scientists think this ice might be a useful source of water for future humans.
  • The researchers had researched 8 locations on the surface of Mars.

Scientists have unearthed thick and massive deposits of ice in some regions on Mars.

The images taken by the High-Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) showed the three-dimensional structure of massive ice deposits on Mars.

The ice sheets extend from just below the surface to a depth of 100 meters or more and appear to contain distinct layers.

It extending downward from depths as shallow as 1 to 2 meters below the surface, which could preserve a record of Mars’ past climate, the researchers noted in the journal Science.

“We expect the vertical structure of Martian ice-rich deposits to preserve a record of ice deposition and past climate,” said Colin M. Dundas, from the US Geological Survey.

“They might even be a useful source of water for future human exploration of the red planet,” Dundas added.

The researchers investigated eight locations on Mars and found thick deposits cover broad regions of the Martian mid-latitudes with a smooth mantle.

However, erosion in these regions creates scarps that expose the internal structure of the mantle.

The scarps are actively retreating because of sublimation of the exposed water ice.

The ice deposits likely originated as snowfall during Mars’ high-obliquity periods and have now compacted into massive, fractured, and layered ice.

Previous researchers have revealed that the Red Planet harbours subsurface water ice.

Recent observations by MRO’s ground-penetrating Shallow Radar instrument revealed a buried ice layer that covers more ground than the state of New Mexico.

NASA’s Phoenix lander had also dug up some ice near the Martian north pole in 2008, however, it is not clear if that is part of the big sheet. IANS

NASA is on the look out for a partner to conduct a contest among students to name the agency’s next rover to the Red Planet — the Mars 2020 mission — in the 2019 academic year.

The Mars 2020 rover mission addresses high-priority science goals for Mars, including key questions about the potential for life on the Red Planet.

Corporations, nonprofits and educational organisations interested in sponsoring the contest can send proposals to NASA.

To be considered, all proposals must be received by October 9, NASA said in a statement on Friday.

“We’ve been doing naming contests since the very first Mars rover back in 1997,” said Thomas Zurbuchen, Associate Administrator for the Science Mission Directorate at NASA Headquarters, in Washington.

“Thousands of kids participate, and their enthusiasm for the contest and Mars is infectious,” Zurbuchen said.
