Back in late June, NASA revealed that sensors on its Curiosity rover were returning alarmingly high readings of methane that came seemingly out of nowhere. Determining where that methane came from — and whether the process responsible for it are geological or biological — is now a major area of research for scientists. A new study led by Newcastle University doesn’t offer a definitive answer, but it does bring us one tantalizing step closer.
In a paper published in Scientific Reports, the researchers effectively rule out one possible source of the methane, arguing that, based on observations of wind erosion on Mars, it’s unlikely that the methane is the result of rocks being broken down and releasing the gas into the air.
