NASA Rover Captures Rock Showing Possible Signs of Microbial Life
NASA’s statement says the rock shows signs of “chemical signatures and structures that could possibly have been formed by life billions of years ago…” NASA

But they noted that additional research is needed to confirm a history of microbial life.

The examinations did suggest the rock contains “organic compounds,” NASA said.

But the statement added, “While such carbon-based molecules are considered the building blocks of life, they also can be formed by non-biological processes.”

The team described the rock as containing white veins that may have been created by the substance calcium sulfate.

Between the veins, examiners found lines of material with a reddish color.

These lines suggest the presence of hematite, a common substance found in many rocks on Earth.

He said that on Earth, these kinds of rock elements are often linked “with the fossilized record of microbes living in the subsurface."

The scientists said the new findings strengthen existing evidence that such rocks may have been created or were changed by flowing water on Mars billions of years ago.

Caltech’s Farley said the rock sample had already been imaged and examined with lasers, X-ray equipment and other instruments as much as possible in recent weeks.

Farley added, “To fully understand what really happened in that Martian river valley at Jezero Crater billions of years ago, we’d want to bring the Cheyava Falls sample back to Ea…
