Mars Odyssey: Does Life Exist On Mars?

A question that has been asked for many reasons in the space world: Is there life on other planets? A mission called Curiosity launched in 2011. Curiosity has been on Mars since August.Curiosity’s goal was to find signs of water and see if Mars was suitable for life. The surprising fact on Mars is there is presence of water. One key element was Mars once had habitable conditions and there looks to be ice on the planet. Curiosity has been using a camera to take photos of Mars. It is much like the panoramic camera we have on Earth. Both cameras have the same material incorporated in them and are used for the same purpose.

For many years scientist from all parts of the world have encountered the idea, “Was there life on Mars, and is there still today.” Never has a Scientist been one hundred percent certain, but a few have been pretty darn sure that life has and still exists on Mars. Bacteria and water have said to be found on Mars a long time ago but is there still bacteria and water on it today. Probes from NASA have gone to Mars to find any kind of lifeform and found samples of water and maybe bacteria. With this finding scientist want to claim for there to be life on Mars but in order to claim that more evidence is needed. At one time Mars was said to have an ecosystem as strong as Earth’s.(Savage, Early Mars) Water was an extraordinary finding for scientist, and the fact that Mars had a very strong Ecosystem gives scientist the upper hand.. The argument about life on Mars can be very well debated on both ends, but the evidence leans more towards that life can and perhaps does exist on Mars.

Ever since the origin of Earth was found, this question has wandered in the air. What will happen when Earth becomes uninhabitable? Scientists have turned to the next closest planet to Earth, Mars. There have been signs in the past of life on Mars. Many think that space exploration could be a reality. On the other hand, many think that the thought itself is unreasonable. Despite the sheet of ice found on Mars (Source D) and the possibility of extremophiles surviving in harsh conditions, the possibility of life on Mars is, indeed, a fantasy. The environment on Mars is too harsh to live in, there have been no signs of life on

Before the sailor flybys in the 1960s, scientist thought Mars had water and life, even if it was just some sort of plantlike lichen. Mars has water, frozen underground and at the polar caps. There is (event(s) or object(s) that prove something) that this water has, in the past and present, flooded the surface in liquid from. Signs of wearing away can be

In Alison Sargent's article, Life on Mars (Hill), she explains how faith and feminism do not easily coexist within a community in Seattle. There is a church known as "Mars Hill Church" in a city full of hipsters, and it is "…one of the hippest, fastest-growing, and most conservative evangelical churches in the nation" (Sargent). The founder of the church is Mark Driscoll, who is also the main pastor. In this church, there is a mixture of pop culture and a strict ideal set, regarding the Calvinist doctrine. This makes for a conservative Christian church with some contemporary and liberal values (Sargent). These liberal values are often "hip", for example the church might have religious services in a coffee shop, or they will have graffiti art

Was there ever water on its surface? Will we find life there? Answers to these questions and others will come from studying and traveling to Mars. ”(Bowers, 1) We only know/see 4% (we only see 4 out of every 100 stars, planets and galaxies) of what is out there in space and we would learn so much more about planets and long-term space travel if we went to Mars because a normal rocket would be too small to be in for about 6 months. We would need to advance in the technology to colonize another planet and we would need to advance in our technology for long-term space travel.

Exobiology is the science that is concerned with the search for life in outer space; it may be called as astrobiology as well. The search for life in outer space has consumed the imagination of the humankind for long time ago. Nowadays, humankind has made a progress and found major discoveries in the quest for life existence in the universe and outer space because of the advancement of the technology. However, in the past, exobiology was considered as a science without a subject, where the people and other scientists laughed at and ridiculed the famous scientist and biologist Joshua Lederberg when he originated the term exobiology. Some people argue that life exists elsewhere in the universe, however, others believe that life only exist on Earth. A new study reveals that our galaxy, the Milky Way, has 100 billion or so stars, where 17 billion of them are Earth-size alien planets, and probably many more. The huge size of the galaxy increases the probability of life existence in the outer space. Are we alone in the universe? This question has captured the imaginations of scientist, theologians, and astrobiologists. However, they don’t know the answer yet. Understanding the complete definition of life and how life originated, and determining the techniques used for searching for life existence in outer space and evidences found can help to answer the question of “Are we alone in the universe?”

Preview Statement: The possibility of life on mars is an extravagant topic to look at. Before that, we must analyze Mars itself along with its conditions. First, we will talk about the ice caps located on Mars. Second, we will examine the water streaks on Mars. Third we will observe if the red planet is inhabitable for humans to conquer it.

Spirit stumbled across rocks that pointed to an earlier, unrulier Mars that was marked by impacts, explosive volcanism and subsurface water [source: NASA Mars]. "Water is key because almost everywhere we find water on Earth we find life," NASA's Web site. However, we are still unsure life existed on Mars.

The soil lacks in nutrients. Therefore, greenhouses would have to be built and constructed in a way that the plants can adapt to the environment in almost a similar way to Earth. This would allow the plants to grow on Mars and over some time, create food for life on Mars. To have this greenhouse on Mars it would help grow plants for food, recycling and for replenishing the air. The main disadvantage to easily growing plants on Mars is the low atmospheric pressure that would make the plants act as if they are quickly drying out and dying. To get around this issue on Mars, we would have to be able to control the air pressure in the greenhouse. Scientists have stated that “A hydroponics system allows the plants to grow without soil, while artificial light ensures the plants are able to grow efficiently”.

NASA says that the MSL mission is part of a long-term plan. This plan uses robots to explore Mars. The most popular question is whether there ever was life on Mars. Looking for the answer to that question is just one piece of a bigger

The change to colder and drier conditions may have forced any ancient life to retreat into the subsurface.9,10 Alternatively, while Mars experienced significant volcanic activity, biological remnants may have been absorbed into ancient rocks, and some organic molecules as an indicator of life on Mars may still remain. Thus, the organic matter within the rock potentially contains information that can be used to determine the past or extant presence of life. On this assumption, if we could show that the production of new living organisms or organelles has occurred independently on

With this trip to Mars we would be collecting core samples by drilling into the ground. Which would tell us if there is radiation and chemical oxidation under the top layer. But the main purpose of going to Mars is to find out if there is life on the planet. NASA states that “Progressive discoveries related evidence of past and present water in the geologic record make it possible to take the next step towards finding evidence of life itself.” (NASA). But the negatives of the going to Mars and trying to find all of these different hypothesis, is that if they don’t work out you wasted all that time and money to get something that does not exist up there. But there is that other side where if they would find everything they wanna find the mission

Luckily for us, the Mars probes has confirmed that Mars would be a very desirable planet to start new life.The proposals to start new life on Mars would impact society greatly, since Mars is an Earth like planet, and there have been traces of water found, it would be a perfect second home. “Going into the ground of Mars will give us a better understanding about the geology of the planet, the presence of water, and whether or not Mars was previously a habitat for life” (NASA, Mars

Mars is the planet nearest to Earth that we are most likely to explore and send
