Curiosity Robot Discover the Ancient Oasis on Planet Mars, Here's the Details

TRIBUNBATAM.id - If asked to imagine the appearance of Planet Mars, what is in your mind? Reddish soil that stretches as far as the eye can see? or the Dried rocks and gravel that scattered?

3.5 billion years ago, Mars's face may have been far different from what it is now. Pools may adorn the Gale crater 150 kilometers wide; and when it's full, the pool overflows and drains the water to the bottom of the crater.

This view is what the Curiosity robot researchers describe in the journal Nature Geoscience. 

They found this ancient oasis on Mars after analyzing the data that collected by the Curiosity robot.

One of the data is regarding the rocks that enriched by mineral salts. 

The rocks which were first visited by the Curiosity in 2017 prove the existence of salt water pools that have repeatedly dried up and overflowed when the climate of Mars is still wet and hasn't become a cold desert like now. 

According to the researchers, the geological formations at that time might have resembled like the salt lakes in Altiplano, South America.

Through this discovery, researchers might be able to answer a question that has been a mystery, that is, when the climate change on Mars occurs and how long it will take. 

The study's lead author, William Rapin, said we went to the Gale Crater because it kept a unique record of changes on Mars. 

"Understanding about when and how the planet's climate began to change is a part of another puzzle: When and how long can Planet Mars support the microbial life on its surface?", he said. 

Gale Crater itself is a geological formation that left over from a collision on Mars. Water and wind then form the shape of this crater, strengthen its sediment and form the Mount Sharp geological formation that is being climbed and studied by Curiosity at this time. (*)
