JAKARTA - Scientists have now discovered that the ancient Mars era may have an environment that can support the underground world or microbes.
The microba is believed by scientists to be able to change the planet's atmosphere, thereby triggering the ice age on Mars and killing themselves. This could be the first evidence of signs of climate change hitting the planet and making it barren for centuries.
The study, initiated by French scientists, was published in the journal Nature Astronomy, stating that the Martian crust may have provided a beneficial environment for microbial life, and the saturated regolith of porous salt water will create a physically protected space from ultraviolet and cosmic radiation.
Major researchers and post-doctoral researchers at Sorbonne University, Boris Sauterey and his team used climate and terrain models to evaluate the habitability of the Martian people 4.1 billion years ago, when the Red Planet was full of water and much more friendly than it is today.
The results show hydrogenotrophs can breed in the soil, but although microbes will emit methane, greenhouse gases, they will eat hydrogen which also has a warming effect.
In just 100,000 to 500,000 years, bacterial activity could change the Martian climate, creating cooling effects that may have pushed the global average temperature from about 60 degrees Fahrenheit to 10 degrees below zero.
"Where the ice-free on Mars could be filled with these organisms," Sauterey said.
Launching The Guardian, Tuesday, October 11, but Mars' early climate, which may be humid and warm, will be threatened by so much hydrogen sucked out of a thin atmosphere rich in carbon dioxide.
"When temperatures drop nearly minus 200 Celsius, any organisms near the surface may enter deeper to survive. On the other hand, microbes on Earth may have helped maintain temperature conditions, given the nitrogen-dominated atmosphere," explains Sauterey.
Scientists noted and observed that this early hydrogenotrophic descendant may still emit methane waste gas, which is cut off in the Martian atmosphere.
Most likely, scientists will get their answers to such questions in the decade.
This is because NASA's Perseverance rover is currently collecting rock samples of Mars and regolith which will then take it to Earth for study in a laboratory that will provide answers, whether there is life on Mars.
