Bugs found in the driest spot on Earth could indicate life on Mars

Freak rains within the driest a part of the world have revealed hidden microbes that might level to what life on Mars may seem like.

Chile’s Atacama Desert is among the most hostile environments on Earth and, very like Mars, it’s arid panorama seems to be fully void of life.

However a current downpour within the South American desert, wherein rainfall may be as little as 8mm a yr, has revealed that a spot that appears inhabitable can really be teeming with life.

Various micro organism, fungi and different microbes have been dwelling dormant below the seemingly barren soil for many years, ready for the very uncommon rainfall to wake them up.

Over a few years the bugs have tailored to the unforgiving dryness, ultraviolet radiation and saltiness, with researchers suggesting that their discovery might be an indicator for the potential for life on Mars.

The findings have been printed within the Proceedings of the Nationwide Academy of Sciences, headed by astrobiologist Dr Dirk Schulze-Makuch, a professor on the Middle for Astronomy and Astrophysics at Germany’s Technical College Berlin.

In 2015, Dr Schulze-Makuch took a staff of researchers on an tour to the Atacama Desert after a yr’s price of a rain was dumped on the realm throughout a freak climate occasion.

They took samples of soil from totally different sections of the desert and returned once more in 2016 and 2017 to gather extra samples.

Within the early samples, Dr Schulze-Makuch and his staff noticed quite a lot of dwelling organisms thriving within the soil however by 2017, because the soil dried out from the sudden rain, the bugs began to return to hibernation.

“Prior to now, researchers have discovered dying organisms close to the floor and remnants of DNA however that is actually the primary time that anybody has been capable of establish a persistent type of life dwelling within the soil of the Atacama Desert,” Dr Schulze-Makuch mentioned.

“We imagine these microbial communities can lay dormant for a whole lot and even 1000’s of years in circumstances similar to what you’ll discover on a planet like Mars after which come again to life when it rains.”

Mars was thought to as soon as be coated in oceans and lakes, an atmosphere deemed extraordinarily conducive to life, however scientists are actually speculating whether or not the microbes might have moved underground because the water dried up.

Because it hasn’t rained on the Purple Planet in a number of billion years it’s troublesome to check whether or not this concept might be appropriate.

Australian firm, Gilmour House Applied sciences, is at the moment working with NASA to construct an experimental rover, which will likely be placed on Mars by 2024.

The rover will likely be designed to drill into the floor of the planet and extract water and will convey scientists nearer to discovering if life on Mars exists.
