Nasa’S perseverance rover started searching this crater to find out if we’re, truly alone, what is the likelihood of life on mars? What would these martians look like and how will we send samples back to earth? This is what, if and here’s what would happen if we discovered life on mars, as scientific american puts it, it would take a near miracle for mars to be sterile. Astrobiologist chris mckay at nasa believes that earth and mars have been sharing materials for billions of years kind of like using your roommate’s spice rack. What i thought you said it was communal, Music, comets or large. Meteorites that have hit earth may have also sent debris onto mars. A tiny fraction of this debris on mars could have carried the same microbes that kick started life as we know it on earth. But what would this alien life look like many scientists agree that whatever life on mars, we might find would need to be incredibly robust with the combination of radiation and freezing temperatures on mars. Could any life form survive such a harsh environment? As far fetched as it sounds, microbiologists have discovered many organisms that thrive in extreme environments, the tardigrade or water bear is a highly resistant extremophile. It can withstand heat, cold pressure, radiation and even a complete lack of oxygen. There are also certain types of bacteria on earth that rapidly produce spores when faced with hazardous conditions. The bacteria can then hibernate during an extended period of drought and withstand intense ionizing radiation.

A team of 1 000 geologists, chemists, physicists and biologists worldwide have drilled 4.8 kilometers into the earth and discovered robust life forms mars. Has a similar geological past to earth so looking underground could be a great place to start by drilling into the gizero crater. We could encounter spores associated with a relatively recent geological era and on future missions to mars, we may dig deeper and uncover fully vegetative microbes to find rock samples that might support life. Nasa’S perseverance, rover uses an array of lasers called a supercam. It can study the surface of mars at a distance. One of the lasers will heat a rock sample and vaporize it. This creates a plasma that can be analyzed to understand its elemental composition. Another laser will reveal which compounds are in the dirt. If the supercam detects organic molecules or elevated concentrations of elements like nitrogen or phosphorus, the rover will head over to take a closer look. It will then scan the soil in greater detail to detect any organic material hiding in the dirt. Nasa’S team on earth has only one shot at picking the right spot to gather these samples with limited space on board the rover. Only a few dozen samples can be collected, so no pressure and fingers crossed if all goes well. Nasa plans to bring back samples known for preserving biosignatures on earth. Biosignatures are faint, molecular traces left behind by microbes billions of years ago, once the samples are collected nasa and the european space agency plan two missions to get them back to earth.

This involves blasting tubes of rock and soil samples into orbit to be collected by another spacecraft and then return to earth whoa. This looks kind of fun. If perseverance’s mission is successful, the discovery of life on mars would be as groundbreaking as the discovery of dna. In 1543, copernicus boldly shook the status quo with his theory that the planets orbited the sun, his discoveries completely changed. Our world view no longer putting earth at the center of the universe. Discovering life beyond earth could be just as powerful, but not finding any life could raise more questions. Is the earth truly special? Are we alone out here? Even if we don’t discover life, these martian rock samples will allow chemists to study the geochemistry, mineralogy and foundational bedrock materials of mars in detail. This could provide us with essential insights into the climate history of mars and help us better understand earth’s climate as well.

Slash what if, in 1976, two viking landers became the first spacecrafts from earth to touch down on mars? They too probed for life in the martian soil and the results are still debated to this day. One experiment indicated that the martian soil tested positive for metabolism on earth. This would almost certainly suggest the presence of life, but another related experiment found no trace of organic material whatsoever, while most scientists have not reconciled the conflicting results. The consensus is that there’s no conclusive evidence of life on mars, but several researchers disagree. Recent discoveries of terrestrial microorganisms surviving outside of the iss indicate that life may be resilient enough for mars and methane in the martian atmosphere could be a sign of microbial methanogens.

A type of microorganism that produces a significant amount of methane stinky aliens, mind you it’s possible that life on mars didn’t have the right conditions to start at all, or maybe it died off from an extinction event similar to the asteroid that wiped out the dinosaurs or It’S even possible that we might end up finding life that was accidentally brought to mars by one of our many rovers let’s hope this perseverance mission doesn’t turn into a 2.7 billion dollar face palm. If mars, is your bag? Well, have you ever thought about setting up shop there with recent developments in rocketry, colonizing mars might be possible in our lifetime. You better strap in because that’s a story for another.
