Humans have always been fascinated with life on other planets and mars is the top dog when it comes to life on it. Humans have been speculative to whether Mars has or had life on it. Even though space travel would be an improvement Mars is too dry, too cold, and Mars rotates out of control so there will never be life on Mars because it is too extreme.
First of all, Mars has very little water and oxygen. The amount of oxygen in the atmosphere on earth is .210 MB, however the amount of oxygen on mars is only .0013. This can have some dramatic effects on this planet. Also Mars has water but it is in ice form and cannot melt because it is too cold. This is a massive drawback for Mars because all the life on earth has to have water to survive. Therefore if no water is on the planet life cannot survive. People do think that Mars did have water millions of years ago, however that does not mean anything because even though the planet might of had water it does not mean life can survive now. Water and oxygen are the main foundations for life and if a planet does not

Just because a planet has water and oxygen does not mean it will have life. This is because life cannot just be thrown into a very cold planet. Life would have to adapt and evolve to resist the cold, which can take millions of years. For example Humans evolved because they needed tools to defend themselves from other species. This took around two million years to evolve, so just imagine how long it will take to adapt to the freezing temperatures of Mars. The reason for this cold is the lack of CO2 in the atmosphere. The atmosphere of Mars is incredibly thin so most of the UV rays just bounce back into space and few stay on the planet. What needs to happen is that CO2 needs to be released into the atmosphere to make it thicker so the UV rays can stay in the planet to heat it. Mars seems promising, however one of the biggest killers is the extreme cold of
... are also starting to consider colonizing the Martian planet for scientific purposes. The Opportunity rover paved the way for Curiosity’s mission to discover life with its findings of mineral veins produced by water underground and surface rocks altered by moving water on the surface. Following these discoveries Curiosity exposed the presence of water in the Martian soil and the existence of habitat suitable for the survival of microbial life for millions of years. With more and more discoveries happening in such a short period of time one can only speculate when we will find the first hard evidence of life on Mars, which appears to be coming in the near future. In conclusion, all of these discoveries by NASA and the Mars rovers have paved the way for future Martian research and people dreaming of one day colonizing Mars, and mankind can only hope for more to come.
The Heavens. Once an object of superstition, awe and fear. Now a vast region for growing knowledge. The distance of Venus, the atmosphere of Mars, the size of Jupiter, and the speed of Mercury. All this and more we know. But their greatest mystery the heavens have kept a secret. What sort of life, if any, inhabits these other planets? Human life, like ours? Or life extremely lower in the scale. Or dangerously higher ().
Supporting the theory that we can colonize mars on mars, Chris Larson wrote, “Liquid water flows, at least sometimes on the planet Mars.” (Larson 1) Needs, such as water, food, and human-survivable climates often aren’t met on other planets, so researchers try to find evidence of these. Water on Mars is a huge breakthrough because of this, as that is one previous limitation of Mars that is now known to not be one. But, there are other options too, such as other exoplanets, as in planets outside of our solar system. “Now scientists have discovered the first Earth-sized exoplanet, dubbed Kepler-186f within the so-called habitable zone of a star.”(____) That is just one example of a recent discovery. Although there might be flaws, it may be plausible to colonize on the surface of a
For example, life, chemicals, rocks, and metals. It is said by some people that there is a strong possibility that there is bacterial life(maybe even more!) on Mars! Other people believe that Viking detected it in 1976. While others say it was in a meteorite. Scientists sent rovers to Mars to check it out. Another thing is, Mars is still mostly unexplored. So, there still might actually be life there we haven’t discovered yet! Also, there could even be new kinds of properties. For example, metals and rocks. The reason why I say metals and rocks is because Mars’s surface is made out of oxidized metal dust and rocks. We can’t tell by just looking at the surface so that’s why we could try finding new metals, chemicals, and maybe even life under the surface too! So this is my second reason. Information from http://www.redcolony.com/features.php?name=whycolonizemars, website is the same from the last
“I think humans will reach Mars, and I would like to see it happen in my lifetime” was said by Buzz Aldrin, a NASA astronaut. The former American aeronaut from Montclair, New Jersey believes that since Mars does exist, it is waiting to be reached by humans. When this would happen, he says that the human race would “evolve into a two-planet species.” Present day Mars has a lot of canyons, mountains and volcanoes. Even though the surface is Mars is very old, scientists learned about different younger rift valleys, plains, hills and ridges. According to recent reports, there were lakes and rivers, along with an ocean billions of years ago. The low temperatures on the planet cause there to be polar ice caps and frozen water present. Scientists continue to notice several discoveries on the planet that lead them to think there was once life on the planet. Different clues have scientists wanting to find out about even more. Many scientists in the past few centuries have been curious if life on Mars is possible or if it has ever been before.
Mars is our next best hope in life on another planet. Because of science mankind can grow and harvest plants in the modified mars soil, make a thick warm atmosphere, and drink no frozen mars water. Mankind can grow and flourish more as a species with this idea of colonizing mars. With more scientific advancements we can colonize mars and we will colonize mars.
Mars had life at one point and we want to find out what had lived there at one time. Mars once had life at one point because we know there was once water because of Mars geography, but there still could be life deep underground (Salazar). We think deep underground there still could be watered and we need to dig deep down to find water if its still there to maybe find microorganisms (Salazar). If there was once life we could find fossils of once living organisms and see what might of happened to them. At one point in time Mars carried life and if we go there we could find what was once there and what could be there.
Mars is a planet that is very cold and barren. NASA says it will bring new answers into the scientific world by exploring Mars from human eyes. We should not put forth a human mission to mars because of the lack of requirements it has to support life. We are also iin trillion dollars in dept and supporting a mission to Mars would make us even more id dept. You will also be on a rocket that takes 1 year at best to get to Mars. That ride alone puts you at a great risk of cancer because of the cosmic radiation.
Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.
By the 2030s, NASA sought to land the first human on Mars. Around 3.5 billion years ago, Mars was suspected to be as suitable a place to live as Earth. Mars is said to be an opportunity to learn more about farming. Today, the planet still has the possibility of fostering ecosystems. Earth’s continental surface area is equal to Mars’s land area.
Since 1976, when the Viking Landers took off toward the red planet, people have been wondering if there is life on Mars. There have been questions of pictures taken from Mars and skepticism about why some of the recent landings have failed. Scientists, up till now, have been doubtful about life on Mars.
Carbon dioxide is an extremely poisonous for humans to inhale which will lead to, when inhaled in large quantities, cardiovascular diseases and nerve damage. Without the doctors and medical professionals required treating this, the individual would succumb to the poisoning and lose their life. Unlike Earth, Mars only contains traces of water and oxygen; two essential substances humans need to survive. Water on the planet is a primary concern. If humans were to settle Mars, where would the water source come from?
With a field as large as space is, metaphorically and literally, there is no end to all the advantages that can come of exploring the magnificent cosmos. One of the major questions we face currently is the possibility of life on other planets. “NASA's biggest ambition is the hunt for life and a habitat that can support life. Several planned or prepared missions will specifically explore the question of whether or not life exists, or once existed, elsewhere in out solar system” (Folger 3). That's exactly what we plan on using the Curiosity rover for. The MSL (Mars Space Laboratory) Curiosity rover was launched November 26th, 2011 and landed on Mars on August 6th, 2012 (Launch 2). “MSL Curiosity's mission is to analyze the climate, geology, and habitability of Mars to see if there is or has ever been life on Mars. Then, after gathering enough data, it will see if it's feasible to send a manned mission to Mars” (Anthony 2). We are already searching ...
One of the most common unanswered questions scientists find themselves asking is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947, the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs, such as The X-Files, and films (Mars Attacks, Independence Day, and the Men in Black films to name but a few). Scientists have come up with many new ideas and ways of trying to either prove or disprove the existence of life elsewhere.
Planet Earth is home to millions of species of life, including ourselves. It is unique in the Solar System because it is the only planet which is able to support a great variety of life: from basic living micro-organisms to highly sophisticated and intelligent human beings. The planet provides the necessary resources and products to support the biosphere that can support the global living organism’s population. Yet, what factors allow Earth to sustain life? Life as we recognize it requires specific conditions to exist. The most basic of these conditions include components needed by living creatures such as water, nutrients, an energy source, and the right atmosphere and climate. Humans need to breathe oxygen and can survive in moderate temperatures- not too cold and not too hot. The atmosphere is like the Earth’s blanket, keeping it warm and protected. Other planets that we know of do not have the same conditions as Earth, so if life were to be present on other planets they would be adapted to that planet’s unique environment. Living things on Earth have adapted to this planet’s atmosphere, therefore we need the specific composition of Earth’s atmosphere to survive.
