Crater on planet Mars may have once held a lake

NASA scientists believe evidence received from its Mars Reconnaissance Orbiter may indicate that a crater may have once held a lake. The latest data supports theories that Mars once had liquid water on its surface.

 

PASADENA, Calif – Images and data sent by NASA's Mars Reconnaissance Orbiter, (MRO), has provided evidence that the red planet may have once had underground water deposits.

That conclusion comes from an analysis of spectrometer data sent by the orbiting spacecraft, which was examining the floor of the 57-mile/92-kilometer-wide by 1.4-mile/2.2-kilometer-deep McLaughlin Crater. Scientists believe that the crater's depth once allowed underground water to flow in to the crater's interior.

A layer of flat rocks of carbonate and clay minerals that compose the bottom of the crater may indicate the past presence of liquid water. The crater lacks large inflow channels and small channels originating within the crater wall near a level that could mark the surface of a lake.

The findings were published Sunday in the online edition of “Natural Geoscience.” Some researchers propose the crater interior catching the water and the underground zone contributing the water could have been wet environments and potential habitats.

“Taken together, the observations in McLaughlin Crater provide the best evidence for carbonate forming within a lake environment instead of being washed into a crater from outside,” said Joseph Michalski, lead author of the paper, which was co-authored by five others. Michalski is also affiliated with the Planetary Science Institute in Tucson Ariz., and London's Natural History Museum.

The MRO, which carries six instruments, was launched in 2005. It has provided more high-resolution data about Mars than all other orbiters combined. Data transmitted by the planetary probe is shared worldwide with scientists, who then research analyze and report the findings.

McLaughlin Crater sits at the low end of a regional slope several hundreds of miles long on the western side of the Arabia Terra region of Mars. As on Earth, groundwater-fed lakes are expected to occur at low regional elevations. Therefore, this site would be a good candidate for such a process.
