The Search for Life on Mars Is about to Get Weird

MESA, Arizona -. Since the dawn of the space age, NASA and other agencies have spent billions of dollars to

on its surface. The possibilities are good, say many scientists, because Mars is an extraterrestrial address of extraterrestrial life, good enough to withstand decades of earth very expensive robots to blow it by the radar, zap with lasers, tracks in their land and collects their

land .

However, despite everything (and researchers hope to discover watersheds), Mars remains a world of poker that keeps its cards tight. No convincing sign of life is evident. But


continue, literally, to detect the truth.
As research becomes warmer (some would say desperate), scientists maintain a growing number of possible explanations for Martian biology in an irregular situation. For example, could there be a “cover-up” by which the environment of severe Mars somehow erases all biological signatures – all signs of past or present life? Or perhaps life is so strange that its biological signatures are not only


, hidden from view.
Of course, the bewildering quest to find life on Mars may have a simple solution: it is not and never has been. But as the work of this year’s Astrobiology Science Conference has specified, in April, life-seeking scientists will not give up. Instead, they become more creative, offering new strategies and technologies to shape the next generation of Mars exploration.

It talks about looking for Martians and inevitably talks about water, almost magical liquid that sustains all life on Earth and seems to function as indispensable starting pedal for biology in the deepest past of our planet. “It all started with” following the water “does not necessarily” follow life “… but” it remains one of the basic requirements for living systems, “says University of Arizona geologist Jack Farmer, referring to the repeated mantra “There are many signs of water on Mars in the past, maybe water tanks in the nearby sub-region too,” he said. “But what is the quality of that water? Is this really salty, too salty for life?
Without liquid water, says Farmer, we naively think that organizations can not function. The reality may be more complex: on Earth, some elastic bodies such as tardigrades can enter a deep state of hibernation, almost indefinitely, when it is deprived of moisture, preserving its dried tissue but not growing or reproducing. It is possible, according to Farmer, that Martian microbes can spend most of their time as inert spores “waiting for something good to happen”, it produces just and very rare conditions. Some varieties of “extremophiles” – microbes living in extreme temperatures, pressure, salinity, etc. – behave similarly.
The farmer said there is still no general consensus on how best to pass the detection of life on the red planet. This is largely due to advances in biotechnology, which has led to innovations such as reduced chemical laboratories to fit a computer chip. These technologies “have revolutionized the medical field, and now they have begun to introduce concepts to detect life on Mars,” he says. Things move so fast that the best technology nowadays to find the biology of Mars can be a stalemate scrupulously obsolete tomorrow.
But no matter how sophisticated a lab on a chip, it produces no results if it is not sent to the right place. Suspect farmer seriously looking for traces of life requires a deep hole in Mars. “I think we’re basically going to have access to the sub-surface and look for the fossil record,” he says. But the discovery of a clear and unambiguous biofirm fossil on Mars would also create a warning signal. “We are probably approaching the future of Mars exploration, particularly in the access to the habitable zones of liquid water in the deep subsoil, with more caution, since life could still be there. Serious, “he said.
