Is there Life on Mars?
Alaina Smith
Georgia Military College Is there life on Mars? Almost every person in science has asked this question at least once in their life. While there are people who believe that there is, there are also the naysayers. Mars is one of the planets that have eluded us for centuries while we have landed on it and done studies; we have still yet to fully say that there was life on mars or that there currently is life on mars. Some scientists have dedicated their lives to finding out the answer. In this paper, both sides will be represented to fully understand this difficult question.
Supporting Arguments Water is needed for life to thrive on any planet, so by proving that there was or still is water on mars, a scientist could prove that there was life. Just last year NASA announced that they found what looked like “dark streaks”

Space Agency has stated that this proof is still not ready to prove that there is life on mars (Moskowitz). They are stating that water does not equal life. While water is crucial for life, it is not enough to prove that there is life on Mars. This article also states that in August 1996, NASA found a Martian rock that landed in Antarctica, which had holes in it that could have possibly contained bacterial life (Moskowitz). This was a huge announcement but has since been discredited with other forms of explanation. Science.org also had a few things to say about the NASA explorations. They stated that the rover Curiosity could not detect the gas Methane on the planet Mars, which is also essential for life (Cho). While this discovery was important it did not prove either way that there was or could be life on Mars. There have been many spacecraft that has flown to Mars and have spotted clouds of methane, but it has not been seen since 2006 (Cho). So this argument is slowly proving that Mars could not support life on it's dangerous
For this purpose, in the past century, scientists have sent several probes and experimental vehicles to the Red Planet to prove that there is a possibility of life on Mars. In the 1960s and 1970s, US Vikings and Soviet Mars probes were sent by scientists and reached Mars. Data from the Viking landers proves that there were water molecules present on the planet. The experimental vehicle, Curiosity, was sent to Mars to prove that these water molecules actually came from lakes, streams or rivers. The Sojourner, a wheeled robot vehicle, was sent to Mars in 1997 and shows plains that look like they were destroyed by floods. This twenty five pound rover took over three hundred thirty feet...
The existence of life – Aliens, beyond our planet has been a controversial topic for several centuries, and is a debatable issue even today in the 21st century. What is our topic you may ask? Aliens, Do, Exist. According to theoretical physicist, Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth. This is a bold claim, but there is evidence to support this statement. The evidence we seek is in the many Alien occurrences we have experienced throughout human history.
There were multiple launches to the moon, all providing pieces to the puzzle about our closest neighbor, the moon. Each mission brought back home evidence after evidence of hydrogen, magnesium, etc. This mission was inspired by the common question scientists and space enthusiasts about whether or not the moon is habitable or if there is any possibility of life. The moon is the closest space object that we can reach, and it’s our nearest neighbor that we know nothing about. It turns out that the study concluded that there is a very small amount of water up there.
Scientists have dreamt over the possibility that it may be possible to live on another planet. Some think that Mars has that potential to support life, if it's hidden resources are uncovered and exploited to their full potential. There is even evidence that it once contained enough water that it had been possible to hold life. Think about it, what if we could transform it into such a place, even if only our children's children get to see any result? The following will describe Mars, present evidence of ice and water, give possible ideas for the future exploration of Mars, and give reasons for why it is important.
Would you want to live on Mars? Some would say yes, others no, I am against going to Mars and think that we should stick to Earth and put our time, money, and energy into fixing this planet. I will show you all the reason why we can not go to that red planet.
Since the beginning of human fascination with outer space, the question “Is there life on other planets?” has existed and has waited to be answered. Early astronomers looking to find life on other planets were brutally punished by the Catholic Church. For years, people saw these astronomers as heretics for going against the church and undesirable, but today there might be evidence that supports these astronomers. Today, we find that people are still split between believing in alien life or not. People devoted to a religion tend to disagree with the possibility of life anywhere but Earth as it goes against their beliefs. However, with the increase of realistic movies about aliens and very convincing theories, many young people are beginning to believe that life on other planets does not seem so radical after all. Each day, scientists find more and more predictive evidence that leads most of them to believe that there is life on other planets.
Intelligent life outside of Earth is one of the most debated topics in The United States of America. There are plenty of shows on television about it and supposedly there has been thousands of sightings all throughout America. Our government is thought of to have encountered and held extraterrestrials. Area 51 is where everyone theorizes that we hold and run tests on aliens, even though there is little evidence. There are also ancient stories told about “gods” coming down and doing inhuman things. In cave paintings you can find UFOs in the pictures, even back then they somehow knew of these flying objects. Most people do not want to recognize that our universe is so vast it would be more likely that there is intelligent life out there than there is not. It is possible that the general population is afraid to acknowledge Aliens’ existence because they cannot imagine a species being more advanced and smarter than us. Another reason people fail to recognize them is because the media has made these “creatures” very far fetched with
The startling discovery took place 43 years after the humankind launched the first rovers, Spirit and Opportunity to Mars. It’s the result of hard work of the best brains, who had one goal: to understand whether we are alone in the universe or not.
Mars, our neighbor planet, is the most explored planet in our solar system, the Milky Way. We have taken a certain interest in Mars, because there is a possibility that it may have sustained life. It is also the most convenient and has the most hospitable climate. That is why we have collected more information about Mars’s atmosphere, physical characteristics, moons, and orbit than other planets.
About 61% of people across the Earth believe in aliens. The evidence that aliens exist is undeniable. Many people have claimed to have seen an unidentified flying object, and some even claimed to abducted by extraterrestrial life. Through psychological tests, scientists are able to confirm the validity of these abductees. The concept of aliens can be used to explain many mysterious occurrences. Whether life outside of Earth may be just bacteria, or something more intelligent, it's existence can be explained through physical evidence. Psychological proof from humans can also be used as evidence and can be proven reliable. Other information about life outside of Earth can be found in ancient, as well as present day signs. I
If we know what makes life on earth habitable, we may be able to figure out how to sustain life on other planets. Using our knowledge about life on Earth will enable us to learn more about information on other planets. It is important to compare the life sustained on Earth and the life on another planet, as they could contrast each other greatly. According to NASA, many missions have taken place and many more will continue in the future (Fletcher 2016). The great number of missions operating shows how significant a question like “Is there life?” can be. This one question can unravel into many more sub-questions, such as the questions described
Recently, two probes were sent back and they made it to Mars. They landed on the South Polar Caps of Mars. That is where NASA plans to find water. After landing on Mars, the probes extracted water like crystals from the surface of Mars. They found that there was a small amount of water in the crystals, which means that there is a strong chance that life, was on Mars at one time.
Statistics have showed 7.5% of rocks from Mars reached Earth. These rocks would travel between less than 100 years to 16,000 years and more to get to Earth. Some proponents include Gyon de Montlivant, who proposed that life came from moon, H.E. Richter, who suggested life came from meteorites or comets, but Svante Arrhenius proposed this theory.
Mars is a very similar planet to earth in relation to size and atmosphere. Therefore it seemed like the most likely place to search for life. At the end of the 19th century, an American named Percival Lowell built himself an observatory so that it was possible for him to study Mars in intimate detail when its orbit was closest to Earth. At this time it had recently been suggested that the planet had a system of channels on the surface, present from the evaporation of flowing water. Looking through his telescope Lowell became convinced he could see a network of artificial canals. This led him to believe that there were intelligent beings on Mars who had built these canals. However, spacecraft have now visited Mars and found that there is no evidence of water at all. It is now thought that the lines he could see were the combination of Lowell's overactive imagination, and scratches on the lens of his telescope. We are now searching one of Jupiter's moons, Europa, as this seems to be the next likely place to hold life.
...ws radiation from the sun to expose the surface of the planet, adding to environment changes. If life exists on Mars today, it is most likely hiding beneath the surface. Over the past four billion years Earth has had many rocks blown from the surface of Mars, after much research, scientists say that of the thirty-four meteorites, three have the potential to carry evidence of past life on Mars (Carey, 2006). Researches have gathered evidence and continue to explore for life outside of Earth. Earth has provided these scientists with enough knowledge to understand the components needed to sustain life, therefore any research found is compared to the knowledge already understood about life on Earth. Earth is home to billions of plants, animals, bacteria and all types of living things, it is where human beings have evolved and adapted making this planet our home.
