Curiosity Mars rover discovered iron and sulfur minerals in the bottom of an ancient lake on Mars. Microbes are consuming minerals may find environmentally friendly life in ancient lakes on Mars. Similarly, according to a recent study.
The researchers say the findings are the best evidence suggests that the red planet was ever sustain life in the past. Earlier this year, NASA reported evidence of water on Mars that might sustain life.

In the last studies that published in Science, shows that Curiosity Mars rover discovered the iron and sulfur minerals in a variety of chemical conditions at the bottom of an ancient lake. Chemical conditions that indicate an electron can move in the environment.

This is important because "if the electrons can move, meaning food can be found," said Scott McLennan, a Geoscience professor of Stony Brook University. "Basically, there are microbes that can take a stone and is a very common thing on Earth (in caves and thermal vents). They are primitive life forms, but it is very well known and understood."
A series of research papers say that there might be life on Mars, but this evidence is first evidence that convincing Hap McSween, a Planetary science professor at the University of Tennessee. "Previously, we found evidence of water. We found this and that, the various fractions puzzle, but never complete," McSween said. "And this place seems to indicate a complete proof."
Samples were taken not far from the place where Curiosity landed, in geological formations known as Yellowknife Bay. Rover does not have the tools to search for microbial fossils that could answer the question of whether there is life on Mars previously. "Ultimately, we would do is start the process of collecting samples from Mars and bring it to Earth, " McSween said. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS | THE BLAZE]
