Astronomers Might Have a Way to Solve the Methane on Mars Mystery

Some evidence of alien life on Mars identified a few months ago after the NASA Curiosity Rover discovered methane. The levels of the element were more than 30 times the regular rate. Currently, the Space Agency might be closer than before solving the Mars methane mystery. It all started with NASA’s Mars rover detection of some methane levels, almost 21 parts/billion/unit inside the 96-mile-broad Gale Crater.

Such a thing was far higher than the believed background density at Gale, which NASA has measured rates seasonally from 0.24 ppbv to 0.65 ppbv. The result created some significant headlines around the world as methane is linked with what represents life on our planet. However, the picture, as seen from above, mysteriously displays a unique view.

The European-Russian Trace Gas Orbiter (TGO), mainly made two detect, such as low-affluence gases, has discovered the air on Mars to be virtually methane-free. TGO, for example, reported a top limit of 0.012 parts/billion methane during its first period of full science examinations. Such a fact represents almost 35 times lower than the background methane levels the NASA probe identified inside Gale at the same time.

Methane on Mars might have a good explanation

Dr. Ashwin Vasavada, the Mars Rover mission leading investigator, confirmed that the difference between ground and orbital calculations has the Curiosity team “mystified, just like everyone else.” Clarifications range from something in the Martian atmosphere crashing down the gas, giving little for the orbiting devices to identify, implied Dr.Vasavada. This is not, however, the sole clarification for the inconsistency.

Dr.Vasavada stated: “Maybe the expansion and contraction of the atmosphere every day from solar heating is responsible.” The Curiosity Rover’s last methane estimations realized utilizing its Sample Analysis at Mars (SAM) device were gathered at night. Moreover, the rover has consequently only searched for methane when the Martian atmosphere was comparatively thick. Such a thing meant that it was far more concentrated.

Dr. Catherine O’Connell, a planetary geologist at the University of New Brunswick, came with some statements. He detailed, “This rare experiment is a chance to get some exciting science observations, but we’ll need time after the experiment to analyze the data; we don’t expect to have any takeaways right away.” Also, even if Mars methane is a biological cause, it doesn’t fully support the idea of active alien life.
