A new report from NASA says that we'll need to dig deeper into the Martian surface in our hunt for signs of life on Mars.
rovers. However, now, a new report suggests that we may need to look further below the surface in our hunt for signs of life on Mars.Our research of the Martian planet has been ongoing for decades. While NASA’s current spacecraft and rovers have learned a lot, there’s still a lot left to find on the surface of the Red Planet. For one, scientists have been looking for evidence of amino acids on Mars. But, the hunt for these key ingredients of life has been disappointing so far.
NASA will need to choose its dig sites for Curiosity based on this new information.

Others were stored at minus 67 degrees Fahrenheit. Then, NASA blasted the samples with gamma radiation to simulate cosmic rays hitting the Martian planet over the course of around 80 million years.
