Mars Facts: Life, water and Robots on the red Planet

It was McKays team that was responsible for uncovering the life-like evidence from the meteorite and stunned the world of science with the announcement the summer before last. We never claimed to have found life, mckay said. But he insists, there were lines of evidence supporting the possibility that life did occur on Mars. He has since added, we have a lot of new data from the meteorite, and we think weve got additional supporting evidence but no smoking gun at this time. (cooke)The information gained from the meteorite suggests that even though Mars surface is fundamentally hostile to life because of the peroxides, and intense ultra-violet radiation from the sun, life beneath the soil may still be possible. The meteorite found in Antarctica seems to have come from deep beneath Mars surface. At the same time that these extra-terrestrial studies have been focusing on Mars, new studies of life in extreme environments on Earth are showing that life survives, and may even have originated, underground. Ken nealson, the microbiologist in charge of the nasa team examining exobiology (the search for life on other planets) said in an interview for Newsday that all of this results in, a very exciting time.

The martian year lasts 23 Earth months, but the martian day is erp only 41 minutes longer than soldier an earth day and its inclination of 24 degrees to its rotational axis is very close to earth.4 degrees. As a result, mars has four seasons that parallel those experienced on Earth. The martian summer is, relatively speaking, warmer than its winter. Mars ids the only other planet in the solar system other than Earth that has polar ice caps, and these can be seen to expand and recede seasonally, just like the ice caps on Earth. Mars is a great deal smaller and less dense than Earth. Mars has less gravity and a much thinner atmosphere than Earth. It is also colder than Earth, with temperatures in its polar regions rarely rising above 200 degrees Farenheit. The midsummer temperature near the martian equator can, however, reach a comfortable (by human standards) 80 degrees Farenheit, closer to an Earthly temperature range than can be found anywhere else in the solar system. (Yenne) Because of that one martian rock found on the ice in Antarctica, and because sciences understanding of biology, especially microbiology, expands so dramatically each year, the thought of life on Mars (in the past and the future) has once again become a very real. The rock a meteorite creatively named AH84001 consists of minerals called carbonates, organic molecules called pahs (polycyclic aromatic hydrocarbons) and small germ-like bodies that could be fossilized microbes, says david Mckay, of nasa. The carbonites especially hint that water once was present.

If the origin of life is life not unique to earth, it means humans exist in a universe that is filled with life. If it is filled with life, how difficult of a cognitive leap is it to assume that the universe is then probably filled with other intelligence as well. From the point of view of humanity learning its true place in the universe, this would be the most important scientific enlightenment since copernicus. The canals charted through a telescope by astronomer Percival Lowell almost a century ago at his observatory in Flagstaff, Arizona, turned out to be just an imaginative figment when Mariner 9 mapped much of Mars in 1971. (Lowell had become a leading exponent of the idea that the canals were constructed by living creatures to irrigate their crops.) five years after Mariner 9, when Americas two viking spacecraft settled onto mars surface, conditions were found to be so hostile that life was. Chemical tests showed the soil on Mars is so rich in potent chemicals called peroxides that organic matter which is needed for life is quickly destroyed. (cooke) In actuality, venus may be closer to being Earth s twin in terms of size, but Mars has more specific characteristics in common with Earth than does any other planet.

His article goes on to defend the human adventure to mars — why we should do it, how to. But one question remains in story every mind who has studied the stars on a clear winter night or wondered what if? After watching a particularly frightening science fiction movie. That singular question, answered in part by the pathfinder Mission, has been. What or who will we find there? In August of 1996, nasa scientists revealed a rock ejected from Mars by meteoric impact which showed strong evidence of life on Mars in the distant past. If scientists can qualify this most amazing discovery, it would undoubtedly demonstrate that the origin of life is not unique to the earth.

There is no evidence or suggestion that any higher life form existed on Mars? (Goldsmith Donald 4 A). The rock contains globules of carbonates mineral deposits made from carbon and oxygen atoms combined with other things such as calcium iron and magnesium. It is uncertain exactly how life arose on Earth but if life also arose on Mars scientists argue that life may well be found elsewhere. However the search for life on Mars has been unsuccessful.

Some portion of the scientific community feels that further searches are a waste of time while another portion remains optimistic.

Although temperatures can occasionally rise above the melting point liquid water from melting ice would quickly evaporate into the atmosphere. In addition liquid water is the single environmental requirement thought to be essential for life. Mars still has water in the form of permafrost water vapor ice-soil layer and at times liquid water.?The network of channels on the cratered surface of Mars showed the liquid water and warm climate allowed the water to flow freely on Mars? On August 7 1996 the world became aware of life life on Mars. President Bill Clinton announced that a meteorite found in Antarctica contains evidence of the existence of life on Mars. The age of the rock dated back over four and a half billion years ago making the meteorite the oldest rock ever found on Earth? These are extremely small single celled structures that resemble bacteria on Earth.

Plant life would be? Because of the atmospheric pressure. Within the canals of Mars the search for Martian vegetation continues. Further more goldsmith 12A scientist of astrophysics had found oxygen and water vapor on Mars. There is abundant evidence that Mars has? In other words volcanoes. A transition from a warmer earlier climate to the colder present vision climate may have resulted from loss of atmospheric gases to space.?Scientists believe there are volcanoes wind-related movement of material ice and water related geology? (Dick Steven J 119D)The average surface temperature of Mars is only about -53 C substantially below the freezing point. Water is said to be abundant on Mars away from the polar caps however liquid water is not stable on Mars.

the soil and some from the polar ice cap. A theory is that? Lived on all the planets. Anaerobes can only live without oxygen. S ozone started to form over half the world? S organisms of anaerobes died off and later evolved to become aerobes which can only survive with a constant supply of oxygen. Scientists believe that the high surface temperatures on the dark areas of Mars may be explained on the presence of living vegetation placed upon a dry vegetable mold. Coblentz a scientist of physics and astrology created a theory that moss and grass might be a reason that the dark areas have a higher temperature than the layers exposed to the sun.

While most of the rocks fell back to the surface some of the debris fired upward by the blast at high velocities escaped the weak tug of Mars? Gravity and entered into orbits of their own around the sun. Scientists believe that the earth? S gravity caught some of the debris and pulled it into the earth. Scientist Digregorio barry e (B4) stated that inside the debris of falling rock were microorganisms. He notes that the microorganisms may have been the very start of life as human civilization knows. There is no way to prove his theory true but it is a strong possibility. Similarities in planets led scientists to believe there is a common bond between Venus Earth and Mars. In August 1960 the new science of astrobiology was given the name?

Mars Essay research Paper, life essay on Mars, if life ever evolved on any of the other planets Mars is the likeliest candidate. After Earth Mars is the planet with the most hospitable climate in the solar system. So hospitable that it may once have inhabited primitive bacteria-like life. Outflow channels and other geologic features provide extensive evidence that billions of years ago liquid water flowed on the surface of Mars. Continuing changes is an accomplishment in modern American technology and it gives the world a step forward in finding the real truth about existing life on Mars. Hurtling in from space some 16 million years ago a giant asteroid slammed into the surface of Mars and exploded with more power than a million hydrogen bombs. This caused huge quantities of rock and soil to fly into the thin Mars?

Researchers have known that water exists in ice form on Mars, but it's never been confirmed if water can remain in a liquid state. In this essay, we'll talk a little about that watery thread that binds all Earthly life, and a lot about how—and where else—it might exist in our Solar System.
