The Mystery of Mars’ Missing Carbon Dioxide
Recent advancements in Martian geology present a fascinating theory regarding the planet’s lost atmosphere. Although considerable evidence supports the notion that water once flowed on Mars, the fate of its thick, carbon dioxide-rich atmosphere remained a puzzle to scientists. Now, researchers from MIT have shed light on this enigma.
Geology professor Oliver Jagoutz and his colleague Joshua Murray suggest a remarkable hypothesis: a significant portion of Mars’ atmosphere is likely trapped within the planet’s clay-rich crust. They theorize that during Mars’ wet periods, liquid water permeated certain rock types, initiating a series of chemical reactions that gradually removed carbon dioxide from the atmosphere and transformed it into methane. This methane may have become stored in the clay, possibly for billions of years.
As part of their investigation, the researchers utilized their expertise in rock and gas interactions on Earth to postulate similar occurrences on Mars. They calculated that the expansive clay coverage on Mars could contain up to 1.7 bar of CO2, which might represent approximately 80% of the planet’s original atmosphere. With this groundbreaking insight, the team believes the missing carbon could be “hiding in plain sight.”
Moreover, they speculate that this hidden carbon might eventually be utilized as propellant, paving the way for future exploration between Mars and Earth. This discovery not only unravels the mystery of Mars’ lost atmosphere but also opens exciting avenues for space travel.
The Hidden Treasure of Mars: Unlocking the Mystery of Missing Carbon Dioxide
Recent advancements in Martian geology have unveiled a captivating theory that sheds light on the enigmatic fate of Mars’ atmosphere. Despite substantial evidence indicating that water once flowed freely on the Red Planet, the disappearance of its once-thick carbon dioxide-rich atmosphere has puzzled scientists for decades. However, researchers from the Massachusetts Institute of Technology (MIT) have made significant progress in addressing this mystery.
Key Insights from Recent Research
Professor Oliver Jagoutz and his colleague Joshua Murray have proposed a groundbreaking hypothesis: a substantial portion of Mars’ carbon dioxide may be sequestered within the planet’s clay-rich crust. During periods when Mars experienced significant wetness, it is theorized that liquid water infiltrated certain rock formations, initiating chemical reactions that effectively removed carbon dioxide from the atmosphere. This process may have led to the transformation of carbon dioxide into methane, which could have been stored in clays for potentially billions of years.
How Did They Figure This Out?
To arrive at this hypothesis, the researchers applied their knowledge of rock and gas interactions observed on Earth and extrapolated these findings to Martian conditions. Their calculations suggest that the vast expanses of clay present on Mars could potentially hold up to 1.7 bars of CO2, which could account for roughly 80% of the planet’s original atmospheric content. This revelation proposes that the lost carbon is not vanished but rather “hiding in plain sight” within geological formations.
Potential Applications for Future Exploration
The implications of this research extend beyond mere planetary science. The team speculates that the trapped carbon might be utilized as a propellant for future missions to Mars. If harnessed correctly, this carbon source could facilitate exploration not only on Mars but also for missions returning to Earth.
