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. …show more content…
Therefore, in the interests of efficiency via proximity to our jump-off point or Earth itself, the next two logical choices would be Venus and Mars. Venus is far too hot to colonize in the near future with a surface temperature averaging 864 degrees Fahrenheit . Mars is quite a bit cooler than that, but we can work with the cold. There are many things that need to be done in order to make Mars more habitable, but with cool temperatures, a thin atmosphere, and close proximity to Earth it becomes the ideal location for the first off-Earth human colonies. Our first hurdle in colonizing Mars will be cost. With an estimated cost of over 6 billion US Dollars just for the initial crew to land on Mars , colonizing Mars will need to be an international effort. Given our limited time and resources, we need to expand past our home planet if we are to survive as a species. This is a huge undertaking that will require the cooperation of all advanced nations, and Mars is the best location to begin our expansion outside of our home planet,
Tracy K. Smith’s “Life on Mars” is a collection of poetry dealing mainly in the search for a sense of purpose and the nature of people. The books is something of an elegy as a whole with many poems pertaining to death and the author’s struggle with the loss of her father. The poems are at once poignant and gentle in tone and leave questions than can only be answered in multiple readings. The book is segmented in four parts that travel through different topics and types of poetry. The mood ranges from passionate accounts of Orwellian politics to soft recollections of a lovers embrace; throughout the book Smith brings in references to pop culture, science, and technology that incorporate seamlessly with her words.
The aim of this paper is to analyze the painting Venus and Mars by Sandro Botticelli and to explore the possible meanings that could be construed from this painting. I will be discussing the perspective, colors, symbolism, light, Botticelli’s intention and painting techniques. Due to the limitations of the word count, I will not go very in-depth about any one discussion versus another but will try to give a broad analysis of the painting. I will also briefly introduce the artist and give some background information on him.
The rise of humanity has become one of the most extreme events in Earth’s history. We have altered nature to fit our desires. However, at this rate, we will ultimately suffocate under our own weight. We are beginning to devour more than the Earth and nature can provide. Unless we scale back our dependence on Earth’s resources, our way of life is almost certainly doomed.
At the U.S. Science Convention of 2011, the dire prediction was made that by 2050, we will have an “unrecognizable” planet by virtue of a huge population competing for a deficient number of resources. It is envisioned that the global population will climb to nine billion by 2050. Due to the increasing population, “we will need to produce as much food in the next 40 years as we have in the last 8,000,” said Jason Clay at the yearly meeting of the American Association for the Advancement of Science (AAAS). The only effective solution is to “minimize population growth…through more effective family planning”. We are now witnessing the truth that lied behind the theory of the economist, Thomas Malthus, who foreshadowed the increase of population with minimal resources to support it.
With all the problems we have on earth and how much we don’t know about our own planet we shouldn’t be colonizing others. We may have the science but we don’t have the funds. We also have tons of willing people but not enough physically and mentally able to colonize a planet. Children are starving all around the world, People are homeless, and wars are starting. Humankind needs to achieve some sort of world peace before trying to explore space. Also, humans will end up destroying life if we try to colonize an
The ecological impacts of space exploration are complex and the actions that we take now will effect us for generations, so it is imperative that we make informed decisions in order to preserve our planet and our solar system for the future. The careless exploitation of resources by humans on earth has already had a negative effect on the environment, pillaging “pristine forests” and leaving in its wake “disrupt[ed] migratory routes, soil erosion and species extinction” (Source E). Since the “final frontier” is still pristine and unmolested by humans, we must carefully consider our actions so we don't destroy space as we did Earth. We must avoid exploiting new resources, conserve the life forms we may find there and leave space in the condition we find it in in order to preserve its purity (Source E). Scientific approaches typically favor preservation and conservation, while a corporation's for-profit approach is disruptive and destructive to the natural conditions. Government sponsored, scientific organizations like NASA, who apprecia...
As the world’s population slowly grows our world grows smaller as well. Resources sustain us, but when there are no resources then what would we do. Our population is always growing, which is a growing problem. Overpopulation has caused an increased resource depletion throughout the world, causing a push for more sustainable ideas.
MARTIAN Every time a space movie comes out that involves NASA and other world space agencies, I have the same thought: In recent years, we’ve somehow lost our sense of wonder about space flight — about the fact that we, as a species, are regularly sending human beings off the planet entirely. And, ideally, bringing them back. And that, of course, is the story at the heart of the movies The Martian and The Right Stuff , the terrific new science-fiction film from director Ridley Scott, opening today in theaters.
The Mars Rover is an AMV (Automated Motor Vehicle). NASA uses landers and rovers. Rovers have several advantages over the landers. They can examine more territory, they have a lot more interesting features, and they can be in any kind of weather.
Since 1976, when the Viking Landers took off toward the red planet, people have been wondering if there is life on Mars. There have been questions of pictures taken from Mars and skepticism about why some of the recent landings have failed. Scientists, up till now, have been doubtful about life on Mars.
Mars and the Earth Geologists study the surface of both Mars and Earth by using interplanetary comparative analysis to further their understanding of the two planets. In some ways, Mars resembles Earth. Features on Mars such as an atmosphere, a wind-modified surface, near-surface water, volcanism, seasons, ice caps, dust storms, and channels can be found on Earth as well, albeit slightly different in origination or intensity. Despite their similarities, their differences are profound. Their acute differences in their tectonic framework and their quantities of liquid water affect the geological theories behind the formation of the surface of Earth and Mars.
The Culture and Commitment of Mars, Incorporated Mars, Incorporated is known to be a manufacturer and distributor of food products (Bloomberg Business). The company manufactures and distributes pet care products, as well as chocolate products; gum, mints, hard and chewy candies, and lollipops (Bloomberg Business). It also offers food products; beverages for various types of work environments such as coffee, tea, and soups. It further provides cocoa extract supplements which helps a person to have a healthy heart because such products allow healthy blood flow (Bloomberg Business). Furthermore, Mars, Incorporated serves various customers from multinational retailers to small independent stores and the like.
Since the first telescope siting of Mars in the 1600s, the Red Planet has been a primary focus of space exploration due to the planet’s suspected similarities to Earth and possibility of being habitable (Mason, 2005). Mars, the fourth planet from the sun, is a terrestrial planet with a desert like atmosphere, strong winds, reoccurring dust storms, and a thin atmosphere composted mostly of carbon dioxide. With temperatures fluctuating from 140 K-300 K, Mars’ climate is almost habitable, and is expected to have previously been much warmer and wetter than it is today (Spohn et al., 1998). Over the past fifty years, explorations to Mars have provided evidence that an abundance of liquid water existed on the Red Planet in it’s past. Mars is therefore a specific target of interest, as the presence of water may indicate that the planet can, or has, sustained life, therefore resulting in NASA’S mantra to, “follow the water” (Naderi et al., 2006).
Terraforming Mars is the process of making mars hospitable to human life and colonizing a safe environment for people to live. Mars, in retrospect, is the most earth-like planet that resides in our solar system, therefore it is the best planet amongst those around earth for us to attempt to inhabit. I would choose to use a timeline of one thousand years to complete the inhabitation process. Most scientist’s timeline is between one hundred and one hundred thousand years, I believe one hundred is much too short and we would be moving to fast and possibly make a mistake along the way. One hundred thousand on the other hand is too long, earths population would be far too high and we would need another environment sooner. Mars has a good amount of resources available for us to use if we make it to mars, these include oxygen, nitrogen, and water.
Mars is the fourth planet from the sun and the last of the solid, non-gas planets in our solar system. Mars is the seventh largest planet in our solar system. The diameter is about 4,220 miles. The equatorial circumference is about 13,259 miles. Earth’s equatorial circumference is about 24,901 miles so Mars’ equatorial circumference is approximately 53.2% that of Earth. The radius of Mars’ core is 1,056 miles. The surface area is 55,742,106 square miles, which is about 28% that of Earth. Mars’ volume is 163,115,609,799 cubic kilometers. The mass is about 641,693,000,000,000,000,000,000 kilograms. The mean density of Mars is 3,933 kilograms/meter3. Mean density gives clues about what the planet is made up of, like how much metal it has, and whether the planet is solid or gaseous (Mars Facts).
