What NASA Found On Mars

This is a rock on the planet Mars and if you look right in the middle here at these dark spots Then you will see what remains of ancient Martian life Or at least that's probably what you're looking at This is what NASA revealed in September 2025 Very well could be the clearest sign of life that we've ever found on Mars The clearest evidence ever discovered of alien life and it's inside a sample of rock Collected by the Perseverance Mars Rover Now what is it about these spots that tells us life must exist on another planet? Well, that is complicated. But today we're gonna figure it out First let's talk about where on Mars the alien rock was found This is the Jezero crater the landing site for NASA's Perseverance rover the most advanced robotic explorer We've ever sent to the Red Planet NASA chose this landing site for a very specific reason It's believed that there was a time billions of years ago when this round basin was filled with liquid water And the reason why we think Jezero was actually an ancient lake is because of this gap in the rim Where we see pretty clear evidence that a river of water has flowed down from the nearby highlands and emptied into the crater That is the spot where Perseverance landed in 2021 at the mouth of the river And that's also where NASA believed that they would have the best possible chance at finding evidence Just like what we are looking at today So if life existed on Mars, then it would have been located in a place just like this But that does not mean it would be easy to find it took three years of exploration before Perseverance Finally came upon this one very strange looking rock poking up out of the sand What makes this rock so special is that dark repeating pattern that runs across the surface? NASA calls the little specks poppy seeds and the larger shapes are leopard spots Now let's establish a sense of scale here before we go any further because the photo that we've been looking at is actually an extreme Close-up. So even the bigger leopard spots are just one or two millimeters across Meaning that the alien life responsible for this would have been very small We're talking about microbes and bacteria which on their own are too small to be found by Perseverance So what we're looking for is evidence that these microbes once existed the things they would have left behind And that is what those dark spots represent a waste product created by active microbial life in very simple terms This is fossilized martian poop Or at least that's the most likely explanation we have right now The first thing that NASA did after spotting the mysterious pattern was to send in the rover's robotic arm And use its full collection of scientific instruments to start figuring out what was going on down there The initial observations showed that this is sedimentary rock meaning that it was formed Slowly over millions of years as the river flowed through and deposited layers of minerals into the muddy ground Then as those layers got compacted down under their own weight and the river dries up eventually the mud hardened into stone On earth sedimentary rocks often contain fossils because plants and animal remains will get caught up in the layers and preserved by the hardening process What's interesting about this particular location is that it contains some of the youngest sedimentary rock that NASA has ever found on Mars It's about three billion years old That means the window for a habitable mars is wider than we would have thought and if true It tells us that there was life on earth and mars at the same time both developing in a very similar way But the only way to know for sure is to go deeper with our investigation You can see this in a self-portrait taken by perseverance in july 2024 The team operating the rover already knew that this would be a moment worth commemorating There's the rock right in the middle of the frame and the little white circle Is where the rover's drill cut and extracted a sample that might someday be brought here to earth for further study But we'll come back to that later Over on mars perseverance was able to provide us with some initial findings that shocked NASA scientists The rover identified two iron-based minerals inside the leopard spots Vivianite and greigite. Now, we often find these minerals inside similar patterns here on earth and When we do it's typically associated with microbial life also known as bacteria Specifically vivianite and greigite are found in the presence of decaying plants and animals Microbes will come in and eat all of that dead organic matter Then they create these iron-rich minerals as a byproduct It's microbe poop It's important to know that you don't need a dead animal on mars to feed those microbes You only need the building blocks of that animal. That is what the bacteria eat and this is what we call organic matter Now here's something to think about 96% of your body mass is made from just four key elements in various combinations Those ingredients are oxygen carbon hydrogen and nitrogen We know that mars contains this organic matter mostly in crater regions where it was brought to the surface by asteroid impacts But there were a lot of organics found inside the same rock that was covered by the leopard spots But that alone does not mean that there is life So we've been in search of more evidence and that's what the vivianite and the greigite provide for us Now we have the ingredients for life and we have the byproduct of life so therefore in order to connect the dots We must have life on mars, right? Well, that's not exactly what nasa is saying They are being very careful to maintain a cautiously optimistic But not decisive tone in their announcement of this new discovery and there is good reason for that Here's a video from 1996 that shows american president bill clinton Announcing the discovery of what appeared to be a fossilized life form inside an asteroid That broke off from the surface of mars and landed on earth in antarctica What they found definitely did look like a little worm, but on closer analysis this turned out to be A non-biological process. It was just water interacting with the rock and creating a worm-like structure So having the president tell the world that you found fossilized aliens, but then it turns out to be just a weird looking rock That's not a good look NASA also did something similar 20 years earlier during the viking missions of 1976 That was the first time the american space program had ever landed on mars And scientists were eager to find the first signs of martian life They had the viking probe conduct a simple experiment where it scooped up a small amount of martian soil And then squirted it with a mixture of water and nutrients The idea was that if there were microbes alive in the soil Then they would drink the water eat the food and create a byproduct Very similar to what we've been talking about so far And in this case nasa was specifically looking for the release of co2 gas from the sample and that is Exactly what they found After the nutrient water was added to the soil It produced co2 which would indicate a biological process and for a moment there Scientists thought they had proven the existence of alien life But the celebration didn't last long while alien biology is one explanation for the co2 It's not the only explanation There are plenty of chemical combinations that can produce co2 gas like when you add vinegar to baking soda Neither of those things are alive and there was no evidence of organic material found in the viking soil samples Meaning there were none of the ingredients for life to exist in the first books So all they really had was a bit of co2 gas and the experiment was labeled inconclusive The astronomer carl sagan coined a very important phrase on his 1980s television show cosmos you would often say extraordinary claims require Extraordinary evidence and that is the route that nasa is taking with their latest discovery on mars In the years since the leopard spots were first discovered Scientists from around the world have been trying to prove that this is not a discovery of alien life Just look at how many names are included on this research paper If the evidence can hold up under extreme scrutiny and no other reasonable explanation can be found Then it might just be enough to be considered Extraordinary and that is where we are right now There are only two other potential explanations for the leopard spots that could disprove the alien theory One is a high temperature reaction the dark patterns could have been formed by very hot water in the range of 150 to 200 degrees celsius that interacted with the rock at some point billions of years ago But the surface of mars is cold and there's no evidence to suggest that this riverbed was ever subjected to high heat of any kind We also know that vivianites specifically can only form at low temperature They would actually have been destroyed by heat if there ever had been any so this probably didn't happen And the explanation too is an acidic water reaction Which says that the spots might have been formed by a very long-term exposure to a very acidic liquid But there's no other evidence in the rock to suggest that it was ever covered in acid In fact, they also discovered a mineral called olivine in the same rock and olivine can't form in an acidic environment so this Probably didn't happen either and that leaves us with the alien microbes In this case, it's the only theory that can't be disproven. So by the process of elimination It's the theory that is most likely to be correct Which means that for the first time ever we can confidently say that there was probably life on mars and this Is wild it would mean that life is not exclusive to the earth You don't need some incredibly rare set of circumstances for this process to begin All you need are the key ingredients, which is basically Just liquid water and organic matter and anywhere in the universe where we find those ingredients We will find life But unfortunately, we still can't say this with 100% certainty and that's because we know the evidence is not complete There is only so much that the instruments onboard perseverance can tell us This is a mobile research laboratory that was blasted into space and then landed on mars It can do a lot, but it can't do everything There are so many more tests that we could run on the leopard spots if we had access to the sample here on earth But we don't and it could be some time before we ever do if ever perseverance has collected 27 rock cores from the jezero crater and its surrounding riverbeds It cuts them out and then stores them in metal tubes that are then left behind on the surface The plan was always that another mars rover would follow along in the near future and collect the samples Then load them up into a return vehicle that would blast off from mars and eventually land on earth with the rocks in tow Mars sample return is complicated and expensive and as of right now The us government does not want to pay the cost for nasa to complete the mission They'd rather Someone else do it and even though nasa has more experience landing on mars than any other organization in the world In fact, the only other space agency that has ever landed successfully on mars is china The chinese have their own mars sample return mission planned It's scheduled to launch in 2028 and arrive back home with the martian rock in 2032 The chinese can afford it. They probably have the technical capability to pull it off And now they know exactly where to go looking for the first real evidence of extraterrestrial life Not that it should really matter who discovers what right? This is about science, but it also does kind of matter doesn't it? This is science that will change everything we think we know about life and the universe and nasa is so close Yet so far away But it's important to remember that none of this is impossible. The money is there We just need the collective will to spend it on a project that will be hard that might fail and will have a timeline That extends beyond the four-year election cycle So it very well could be that a discovery like this the first real evidence of extraterrestrial life Is exactly what we needed at this moment to remind the people in charge that nasa science is important That it's worth investing in One way or another the truth is out there. All we need to do is go out and get it
