Scientists Moving Towards Solving Mystery of Mars Methane Puffing
Scientists have taken a big step in the direction of unveiling the mysterious source of methane on Mars, by refining measures of the gas in the planet’s atmosphere.
The methane puffing from a massive crater on Mars could be a sign of life or other non-biological activity under the planet’s floor. Gale crater – which is 154 km in diameter and about 3.8 billion years old, is assumed by some to contain an ancient lake bed.
The team was in a position to enhance the estimate of methane by utilizing data from a satellite, ExoMars Trace Gas Orbiter, the Curiosity Rover, which accumulates rock, soil and air specimens for onboard analysis.
Dr. John Moores, at York University in Canada who led the brand new study, mentioned scientists had been speculating for greater than a decade as to what the supply of methane on Mars could be.
This new study redefines our perception of how the focus of methane within the atmosphere of Mars adjustments over time, and this helps us to unravel the bigger mystery of what the supply might be,” stated Dr. Moores.
Co-researcher ANU Professor Penny King mentioned there were several equally plausible explanations for the methane detected on Mars.
Last year, scientists discovered that methane concentrations modified throughout the seasons with a repeatable annual cycle.
Dr. Moores said the group was in a position to reconcile the data from the ExoMars Trace Gas Orbiter, the Curiosity Rover, which appeared to contradict each other with wildly different detections of methane.
