Hundred's of millions of years ago, parts of Mars were capable of supporting life for lengthy stretches, new observation by NASA's Mars rover Curiosity suggests.

Curiosity has identified a number of different rocks over an elevation range of about 650 feet (200 meters). This represents a time span of tens of millions to hundreds of millions of years.

As per the report from the American Geophysical Union, The Rover's analyses the environment within Gale Crater changed considerably during this period. But this had never in a way that would preclude life from forming or surviving.

According to SPACE, The Curiosity made the observation by drilling into the rocks on Mars. The scientists have collected resulting samples and determine that Gale Crater harbored a potentially habitable lake-and-stream billions of years ago.

The new findings have painted the most detailed picture of the environment on Mars and give details of how it changed over time. The results are sought ting more finding that Curiosity has performed as it climbs the foothills of Mount Sharp, which rises 3.4 miles into the sky from Gale Crater's center.

The primary observations of Curiosity of lower elevation suggest the lake was first tranquil of fresh neutral-PH water and time to time changed acidic and then a bit saltier.

The lake system on Mars was probably dried at times and then filled back in again, as the groundwater level rose, reported by John Grotzinger, the Curiosity science team member.

The researchers find that, despite all these changes the area remained hospitable to microbial life. The curiosity has also detected Boron in Gale Crater; this element has discovered first time from the Mars.

Curiosity Science Team Member assures, Curiosity will continue climbing up Mounting Sharp lower reaches and also find out the changing behavior of ancient Martian environment.

Curiosity is part of NASA's ongoing Mars research and prepares for human mission to Mars in the 2030s
