Our Best Instruments Couldn’t Find Life on Mars - by ET_Exists
The research team, which includes co-author Dr. Alberto G. Fairén, who is a visiting scientist in the Department of Astronomy at Cornell University and a research professor at CAB, claim detecting organic materials within Martian rocks using current instruments and methods on Mars could prove to be difficult, if not impossible.
While the team was successful in identifying a biosignature combination of present and past microorganisms, they found these microorganisms were rather difficult to detect despite the team’s state-of-the-art laboratory equipment. The team also identified what they referred to as “dark microbiome”, which are microorganisms whose classification cannot be determined.
The researchers noted two options in the study: sending better instruments to Mars or examining samples returned from the Red Planet “to conclusively address whether life ever existed on Mars,” the researchers note in the study. Dr. Fairén says both options are extremely difficult.
