Once a Great Lake? NASA’s Curiosity Team Confirms Ancient Lakes on Mars

On October 8, 2015, NASA reported that billions of years ago, Mars was capable of storing water in ancient lakes for a period of time. The Rover landed three years ago into the Gale Crater, coincidentally the location where water aided the deposit of sediment on the planet. The sediments deposited where the layers that formed Mount Sharp, the mountain in the middle of the crater. About three billion years ago, a series of long-lived streams and lakes existed at some point, delivering sediment that slowly built up the lower layers of Mount Sharp.

            In other news, NASA scientists confirmed that water currently flows on Mars. Billions of years ago, Mars  more closely resembled Earth than it does today. What happened to the once wet Mars?  They estimate that less than 500 million years ago, the fillings of the bottom of the mountain were made perhaps by ancient lakes or rivers.

Scientists discovered water-deposited, fine-grained rocks close to Mount Sharp. Scientists found mudstone which concludes the presence of bodies of water that existed hundreds to millions of years ago. But, what about the original source of water that carried sediment into the crater? For flowing water to have existed, Mars must have had a thicker atmosphere and a warmer climate. Just as NASA said, “something is missing somewhere.”

The “Garden City” in Mars

Curiosity examined bright and dark mineral veins at a site called "Garden City," where some veins protrude as high as two finger widths above the eroding bedrock in which they formed.

     The diverse composition of the crisscrossing veins points to multiple episodes of water moving through fractures in the bedrock when it was buried. During some wet periods, water carried different dissolved substances than during other wet periods. When conditions dried, fluids left clues behind that scientists are now analyzing for insights into how ancient environmental conditions changed over time.

     Thanks to NASA's Curiosity rover, scientists now have a better understanding about a site with the most chemically diverse mineral veins.

Discovering Mars with the Latest Technology

          The Mars Curiosity Rover has been equipped with advanced computer technology facilitating its adaptation to the challenges present in the red planet. Curiosity has two computers, which allows to storage small amounts of data that is automatically saved in the event that electric power is interrupted.

          Engineers on Earth, on a daily basis, send instructions to the computer in order to achieve the activities of the day. Curiosity has a laser with the ability to recognize the rocks and theirs characteristics. It also possesses a seven-foot long arm that can reach Martian soil and rocks and that is able to find out about what the past environment was like.

          This robot has made it possible to find details about Mars that we may have not known before thanks to its technological advanced system.
