Mars is a planet that is described as cold and dry. However, approximately 3 billion years ago Mars had liquid water running along its surface, which scientists believe could have helped microbial life flourish (Wall, 2016). Scientists have believed for many years that there are specific elements required for life to exist; hydrogen, oxygen, carbon and nitrogen (Wall, 2016). In some habitats scientists have discovered some species that can survive without some of these elements, leading researches to believe that life could potentially survive with much less on other planets in the universe, like Mars.
A complex organism like a human requires many different elements for survival; the four main elements include carbon, oxygen, nitrogen and hydrogen

This field would have protected the atmosphere from most of the suns radiation, as well as potentially been able to hold more oxygen in the atmosphere, allowing life to flourish (NASA, 2016).
Scientists have found evidence of several different elements being found on Mars, that suggest potential life could survive presently, in the future, or perhaps in the past. Mars has an atmosphere that is about 1% of what the atmosphere on Earth is (Sharp, 2012). This meaning that the planet is not protected from the suns radiation, at is about 95% carbon dioxide, lethal to humans, but may have had potential to sustain life in the past (Sharp, 2012).
Mars rovers Opportunity and Spirit were meant to complete their original mission in April 2004, but are still operational and sending back more information about the terrain on Mars (Rayal, 2016). Perhaps one of the most interesting discoveries these rovers have unearthed is a substantial silica deposit, roughly 90% pure silica, found nearly 1,200 days after first touchdown on Mars (Rayal, 2016). What makes this so interesting is that for this much silica to be formed, scientists believe that the presence of liquid water must have been part of the process in creating this concentration of silica (Rayal, 2016). The amount of water needed to create this deposit would have been large enough to potentially

The rover landed in Gale Crater, which is believed to have been at one time, a great lake. Mars has signs of several large lakes where water would settle for periods of time, as well as many rivers and streams that ran into another (NASA, 2015). When people think about life in space, they usually think about current or future life forms. However, much like several civilizations on Earth, there may have once been life on Mars in the past, that have now vanished into the dusty atmosphere that now covers most of Mars. These vast water ways are believed to have been able to sustain life, approximately six billion years ago (NASA, 2015). NASA is planning on launching a new mission to Mars in the mid 2030’s, equipped with more advanced technology that would be able to dig deeper into the sediment to retrieve larger, more accurate samples, and hopefully tap into some underground reservoirs (NASA,
I hope I have educated you and answered some questions. I have written as much information as I could find on these life crucial elements. These elements are very important and crucial to our life.
Imagine very little water source, never returning to Earth. Imagine standing in the middle of a sand storm, one of the many dangers on Mars. With no return to Earth, barely any water, hard conditions and dangers for anyone who goes, regular sand storms... This all proves that NASA should not send people to Mars. There’s a lot more research about space and Mars that needs to be done so we can know what other precautions to take before humans go and settle on Mars.
Humans, bears, and trees all have one thing in common, they all have atoms and molecules. They also need the four elements of life to survive, Carbon, Hydrogen, Oxygen and Nitrogen. An atom is the smallest part of an element that is still that element. A molecule is two or more atoms joined and acting as a unit. There are four different types of molecules, they are, carbohydrates, lipids, proteins, and nucleic acids.
I believe that it is possible for Mars to have the ability to support life because of the possibility of there being water increases the probability of organisms being able to exist on Mars’ ecosystem, therefore the chance of Mars being able to sustain life. Furthermore, even if water never did or will, as a matter of fact, exist on Mars there is a chance that an organism is able to survive without it.
Mars is most likely planet that has the ingredients of life that is need for a living organism in the solar system other than the known planet Earth. These ingredients of life are the following. The planet in question must be at the correct distance from a host star. Mars is a planet that is on the outer edge of being correct distance of its host star. Next item is that the planet must have water. Mars has water but its water is frozen in the planet ice caps or under the soil. Last is that the planet must have an atmosphere that is suitable for living organisms. Mars’s atmosphere is weak and it is being blown away by the solar winds form the host star. (""Life" on Mars") With Mars’s weak atmosphere the surface temperature of the planet is every cold and the water on the surface of plane...
“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.
National Aeronautics and Space Administration (NASA) launched two similar twin robotic rovers, which were Spirit and Opportunity toward Mars on 10 June and 7 July 2003 (NASA 2012). Spirit and Opportunity landed in Gusev Crater on 4 January 2004 and in Meridiani Planum on 25 January 2004 respectively (NASA 2012). Opportunity is still operating and roving after 10 years on the Martian surface while final communication of Spirit to the Earth took place on 22 March 2010, which is around six years into its mission (NASA 2012). The rovers were thought to last 20 times longer as compared to its original design. As part of NASA’s Mars Exploration Program, the Mars Exploration Rover mission is a continuing multi-mission effort to study Mars as a possible habitation for past or present life and to look for signs of life as well as to prepare for human exploration. Primary objective of the Mars Exploration Rover mission is to explore and characterize a wide range of soils and rocks that possess clues or evidences to past water activity on Mars (NASA 2012).
There is, however, rising speculation that Mars currently holds ice and possibly flowing water in certain areas on and under the surface. Because of the surface conditions, the water would evaporate very quickly and not be directly visible from space, along with the possible exception of the polar caps, which will be discussed later. Almost all researchers and scientists believe that there is ice on Mars, but the trick is to find it and use it to our benefit.
There are over a million different planets in our universe. There is not one planet like the other, though some people may argue with this fact. Jupiter, Saturn, are all gas giants, but they also are made up of different gasses. Jupiter is made up of mostly hydrogen, Saturn is made up of hydrogen and helium. I am sure that everyone knows that the rock planets are not alike in many different ways, there is mercury which is very hot, and most likely just a planet of lava. Then there is earth which is rock and water. All that being said life could exist on any planet with water and solid ground. In my own opinion, I think that life could exist on other planets than our own. Life can exist if there is the tiniest spec that can grow, evolve, and become whatever it needs to survive. Honestly how does one think that veins of water on mars were formed?
The water contained under the soil has had some various effects on the Mars terrain. When the robots were on mars collecting samples, they found some rocks that looked like rocks from prehistoric life here on earth. When analyzing these samples, the scientists deemed that the water was very acidic and salty. This is similar to some of the earlier times in the Australian area.
Five Easy Pieces: Transgressive Fiction, Heterology, and the BBS Style The opening image of Five Easy Pieces sets the stage for the introduction of the main character, creates a framework for the development of the story, and creates an unambiguous visual illustration of how the movie exemplifies films made under BBS Productions, the innovative company which produced movies for a short period of time from around the late-1960s to the mid-1970s. BBS contributed several notable films during the period and gained a reputation as main players in the Hollywood Renaissance. The scene combines Classic Hollywood filmmaking, learned in film schools by young first-time directors given total control of their films, with experimental techniques for storytelling and editing inspired by the French New Wave Cinema, along with the
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.
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 ...
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.
Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
