One– unless they are NASA’s main objectives Perseverance Mars has astrobiology, to study the signs of microbial life. This will help develop opportunities for people-led excursions or future settlement.

Alongside observation that naturally formed caves can provide protection of the otherwise promising discovery of otherwise dangerous amounts of radiation is a pair of rock samples that point to water.

It has been it was known that the Jezero Crater, the area Rover was exploring, was in the past ancient lake. However, it has been difficult to determine how long the lake existed and whether it was there for millions of years or just a flood of flooding.

But now, the stones reveal that water was indeed present for a long time.

Of the two, Perseverance Rover took the first sample called Montdenier on September 6th. Another, Montagnac, was collected from the same stone on 8 September. Both are currently safely stored inside the Rover.

Analysis the stones revealed that they were basaltic in nature, possibly derived from lava flows. Salts were found inside them, and this is not part of the natural stone.

It was suggested that salts may have formed as groundwater flows through the rock and “changes the original minerals.” Another possible explanation is that when the liquid water evaporated, the salts were left behind.

Both suggest the presence of water, which in turn refers to the presence and possibility of life.

“It looks like our first rocks reveal a potentially habitable sustainable environment, ”said Ken Farley of Caltech and a researcher on the Mars mission. “It’s a big deal that the water was there for a long time.”

Team wrote in a press release that ancient Martian water may also have remained in the rocks, trapped in small bubbles. If so, they would “act as microscopic time capsules” to provide information about the planet’s ancient climate and habitability.

In addition to crystalline minerals the presence of the rocks allows scientists to update the rocks more accurately and learn more about the history of the crater as well as the geological history of the mysterious red planet. Salt is good to store here on earth, and it’s the same on Mars.

By Mitch Schulte, the program’s program researcher, said the rock samples “are of great value for future laboratory research on Earth,” and will one day “help answer the big picture of the scientific question about the history and stability of Martian liquid water”.

After toughness the first sampling attempt turned out to be somewhat a flop, it is safe to say that Rover has redeemed itself with this endeavor.
