Mars is one of the most fascinating planets among all the other planets in our solar system, mainly because it is very similar to the Earth. For centuries scientists have speculated whether or not there is the possibility of life beyond planet, Earth. Ever since the discovery of water particles in the form of ice on Mars, the theory on the probability of life on the planet is now seen possible because, according to scientists’; Mars had a warmer and habitable environment about some billion years ago this can be seen by the various canyons on the planet. Mars is of particular interest for the study of the origins of life because of the striking similarity to the Earth. Also the seasons on Mars are quite similar to that of the Earth but, however, it is twice as long when compared to the Earth. It would be possible to create human-friendly living conditions there. In addition, scientists have discovered that the current atmosphere on Mars resembles Earth's atmosphere a billion years ago. They speculate that the process that warmed up Earth's atmosphere to allow plant and animal life to exist can be repeated on Mars. Furthermore, Earth and Mars share the basic elements needed for life to exist (carbon, oxygen and nitrogen), albeit in different amounts. .For example, the Martian day is very close in duration to Earth’s; a solar day on the Red Planet is around 24 hours 39 minutes and 35.44 seconds (Mars one).
For Humans to survive on the Red planet some of the basic conditions should be fulfilled, such as water and oxygen, which is not easily available. The air on Mars is mainly composed of carbon dioxide which is around 95% followed by nitrogen which is about 3% and other gases including oxygen which is less than 0.4%. Furthermore, the...

...eing considered, as the technology to start a civilization is available but at a certain cost. The question of whether there is life on Mars has fascinated mankind for some time even long before the first mapping of the red planet in 1877. And it seems that we're no closer to a conclusive answer today. While authors, scientists, astronomers and even Hollywood have long grappled with this question each proposing a suggested life-form on Mars ranging from scientifically likely to science fiction imaginary, they have continued to explore Mars in the ever-increasing quest to find evidence of life there. To date, samples of Martian soil have suggested only chemical, but not biological, activity. It seems that the closest we're going to get to an answer about life on Mars is that there may be bacteria lying dormant there, perhaps in the regions of Mars' icy polar caps.
In conclusion Mars does have the potential of supporting life, but it might be different life than humans, since the properties of the macromolecules of life might change. Water is essential for life and useful in many ways, such as regulating temperature. The NCHOPS series can be mostly found on Mars, if they are not they can be replaced by the elements that are both found on Mars and need the same number of bonds to become stable.
“That's one small step for man, one giant leap for mankind,” were the now famous and iconic words or Neil Armstrong as he became the first man to set foot on Earth’s moon. The advanced research mankind has made to further their understanding of the vast, astronomical unknown of space has opened up numerous doors of opportunity to fathom the universe, but not without drastic repercussions.
Abstract: How do different minerals found on other planets, affect the growth of bacteria. In this experiment, I will study the effect that extraterrestrial minerals have on the growth of E. Coli bacteria. To do this, I will prepare growth media for E. Coli, supplemented with increasing concentrations of minerals and chemical compounds found on the surface of the Moon, Mars and Vesta. Bacteria will be grown in liquid media or on petri dishes and their growth will be determined by the density of E. Coli in liquid media or by the number and size of colonies of E. Coli in petri dishes.
In the speech, “A Plea For Our Planet”, Severn Suzuki addresses several facts regarding the current events, though the main point she preaches is if adults don’t change their ways future generations will lose their futures. Suzuki tackles 3 points in her speech, she tackles environmental, political, and poverty issues. She first criticizes adults in wealthy countries who have an astonishing amount of money. She says, “I could be a starving child in Somalia, or a victim of war in the Middle East, or a beggar in India.” Suzuki’s right, children in developing countries such as: Afghanistan, Albania, and Algeria, are in more risk of starving than wealthy countries like: Canada, the U.S, Germany and Spain. Parents in developing countries work harder for less and don’t have access to the luxuries we have. Victims of war lose some of their dearest valuables, (and here the adults that have the power to start and stop wars are again criticized): family, friends, homes, and lives. For instance, look at Palestine, violent persecution and occupation of Palestine is occurring, yet no wealthy country will bother to stop it. When Suzuki says, “Victims of war”, she means the people that suffer the consequences of the actions of western countries.
Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found, communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect. Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.
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.
Recent work has revealed the existence of a group of bacteria that are as different from other bacteria as the latter are from plants and animals. This discovery compels the reorganization of all life forms into a family tree unlike the traditional ones. Out of this reorganization comes a strong suggestion that there is a single ancestor to all modern forms of life. ( Edey, pg.297 ) The abundance of evidence that there was life much earlier then ten thousand years ago makes it easy to disprove the view of the Creation-scientists.
It has been hypothesized that life will form and evolve whenever the energetic, chemical, and geological conditions are met. Life is commonly thought to have emerged on Earth. However, through recent studies, Mars has become a very probable candidate for life, but it may have been destroyed before it could into the more complex life forms that exist on Earth today. But so far, we have only seen the surface of Mars. Little is known about what lies beneath the surface. It is commonly theorised that Mars once held vast oceans. However this was millions of years in the past. But since the recent discovery of flowing water on Mars, hopes have risen for astrobiologists searching for any form of life that may have survived under the surface.
What Makes Earth Different From Mars Earth is the third planet from the sun in the solar system, and was formed over four and a half billion years ago. The planet earth revolves around the sun in three hundred and sixty five days, and has only one moon. Mars is the fourth planet from the sun in the solar system considered to be similar but very different from earth. Some of the differences between Earth and Mars are the size of the planets, the plate tectonics, and the ability to sustain life.
The human race has begun to evolve past its infancy, and in doing so placed itself at a critical junction. We now know that not only our resources, but also our habitable land, and even our time in the Sun are limited. Eighty percent of the countries on Earth are using resources faster than can be sustained by the biosphere . As the human population continues to increase, keeping our consumption in check will become more and more difficult. Since halting population growth is not likely to settle well with most people, we are left with little option if we are to survive. We must expand our biosphere beyond the reaches of our home planet. Our closest celestial body, the Moon, has no atmosphere, very little gravity, and little mineral diversity.
The question of whether there is other intelligent life form beside humanity has been in great academic discourse for much of the last century. Many conspiracies about intelligent life forms have emerged and inspired many great works of art in various genres. Although definitive proof of their existence has yet to be found, the search for intelligent extraterrestrials have lead innovations to new heights in space explorations. This research will attempt to show with good reasons that it is unlikely for intelligent extraterrestrials to exist, but the possibility of microorganisms to live beyond our solar system is plausible. Schick and Vaugh define “extraterrestrial” as an intelligent being foreign to earth.
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.
Humans can expect to face some major challenges on an expedition to Mars. It has been proven that humanity can travel in space for over two years. Cumulatively, Sergei Constantinovich Krikalev, a Russian cosmonaut, has spent over eight-hundred and three days in Earth orbit (Lyndon B. Johnson Space Center, 2005). The expedition to Mars would require the crew to endure a six month journey to the planet, a year of living on the planet, and a six months journey back to Earth. Russian cosmonaut, Valery V. Polyakoz, clocking in at four-hundred and thirty-eight days for just one stay in Earth orbit, shows humanity is capable of a twelve month round trip to Mars (Schwirtz, 2009). Earth's orbit has provided some benefits to space exploration, like the magnetic field from cosmic radiation, and the proximity to Earth if an emergency were to arise (Jones, 2009). The further humans travel away from Earth the greater the risks become. The major risks to human health on a flight to Mars, living on Mars, and returning to Earth are: radiation exposure, biological problems induced by weightlessness, spacecraft malfunctions, and psychological problems brought on by isolation.
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.
