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.
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.
Scientists have dreamt over the possibility that it may be possible to live on another planet. Some think that Mars has that potential to support life, if it's hidden resources are uncovered and exploited to their full potential. There is even evidence that it once contained enough water that it had been possible to hold life. Think about it, what if we could transform it into such a place, even if only our children's children get to see any result? The following will describe Mars, present evidence of ice and water, give possible ideas for the future exploration of Mars, and give reasons for why it is important.
The fourth planet from the sun was named after the Roman god of war, Ares and the Greek god of war, Mars. The month of March was named after him so the Romans believed that March was the time of war. Juno, wife of Jupiter, became pregnant with him when Flora, the goddess of flowering and blossoming plants, touched her. Mars was known for his outrage and fury. He is said to have loved battle and killing. He raped a Vestal Virgin, Rhea Silvia. This led to Mars having two sons, Romulus and Remus, who would later found Rome.
Progressive reformers believed in individuality and were not looking to capitalize from the movement, they instead sought out equality in every aspect of American lives and were successful in many instances. Progressives fought to end what seemed to be a myriad of social issues that were bound to arise as the country rapidly grew in several facets.
At the 1899 Hague Peace Conference, it was declared that any combat from aircraft would be considered a war crime. (Eyffinger 227) Merely 20 years later, World War One had seen the daily use of airplanes and pilots for unyielding combat. While slow at first, the recognition of the power of aircraft was quick as the Great War started. Out of all countries involved in the war, Germany had the deepest trust in their aircraft, and this would shortly be to their advantage. Whereas numerous air forces were by now in working condition, the fighting usage of airplanes was minimal. The airplanes were used mainly as recon, but the potential for air combat was yet to be seen. As the number of air force recruits increased, the number of planes manufactured followed suit. Through “hero pilots,” the air forces were used as propaganda tools, and the honour of being a pilot was never modest. Whether multiple wings for stability or lighter frames for speed, airplanes were under continuous upgrades. The rise of airpower overshadowed any other advancement of WW1. Through the advancement of aircraft and the use of hero pilots, WW1 transformed the role aircraft played, gave a much needed boost to morale and pride and presented vital advancements to aircraft technology.
In conclusion, although the zeppelin was an impressive and remarkable step in aircraft development in the history of Germany, it prove to be a fair weather aircraft that was never meant to participate in wars or flying through harsh weather and with the development of aero planes, the roles of zeppelin was made obsolete and ending its era as an aeronautical dead end .
However, before doing this we had to look more into depth on the materials we will use to construct our bridge. We also have to consider the possible environmental and geological factors that should be taken into consideration for our model. Pertaining to environmental and geological factors, there are many stipulations that structural engineers take into consideration before the construction of a truss bridge begins. The main objective of the geotechnical engineers are to protect the lives of others and avoid property damage from happening which can be caused by various geological conditions. Geological engineering uses principles of soil and rock mechanics to find surface conditions and materials.The Geotechnical engineers complete works such as: geological hazard assessments, material properties, landslide and slope stability, erosion, flooding, dewatering, and seismic investigations. These engineers closely examine all of these important factors before constructing a bridge in a certain location. According to Teach Engineering.com, constructing a safe and efficient bridge requires an ample amount of time and energy. Environmental and geological factors play a major role in construction, as
When one thinks of great aviation pioneer, they usually don’t think of Mr.Sopwith, the designer of a good portion of old british war planes. However the Sopwith company design elements and availability is something to be remembered, especially during the first world war. While Sopwith wasn’t the only aviation company to supply the british war effort, the Sopwith Camel is one of the most recognized planes of the war, for good reason too!
Mars is our next best hope in life on another planet. Because of science mankind can grow and harvest plants in the modified mars soil, make a thick warm atmosphere, and drink no frozen mars water. Mankind can grow and flourish more as a species with this idea of colonizing mars. With more scientific advancements we can colonize mars and we will colonize mars.
The progressive movement initially began as a reaction to political and corporate exploitations at the turn of Twentieth Century, fighting for political and economic equality between people, as well as helping the poor. The four new Amendments: the 16th, 17th, 18th, and the 19th, added to the constitution between the 1900s-1920s, which was the time period of the Progressive Era, the federal reforms, and the state reforms, evidently validate the purpose of Progressive Movements and corroborate the necessity of the movements at that time period, as they greatly changed and affected the American life.
People have been venturing out into the universe for many years now. In addition to satellites, both women and men astronauts have traveled into space to collect data about the universe. The first human being, the first animal, and the first spacecraft in orbit, were all achievements of the Soviet Union.
The recent events regarding the NASA Mars probes have renewed the debate of reinstalling manned space missions with the objectives of exploring and landing on foreign worlds such as the moon and the red planet Mars, rather than the use of solely robotic craft and machines. It is my belief that we should return to the days of Neil Armstrong and Buzz Aldrin, those of manned lunar landings and manned space exploration. Robots simply cannot and should not be allowed to be the sole means of visiting these worlds, nor should humans only be able to witness new findings second hand through the use of computers and machines. It is human nature to be normally curious of one’s surroundings, and it is important that we send one of our own to new worlds. The effects that past missions have had on the world’s people, as well as our political and cultural climates are another valid reason for flesh instead of metal to lay claim to space. Also, the limitless applications and new education that manned flights can bring to us from on site human interactions could lead to another technological and industrial revolution like the original lunar programs had done for us during the Gemini and Apollo programs.
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.
As a civil engineer, one must focus mainly on the design and implementation of transportation based structures such as bridges, roads, highways, airports and tunnels. Specifically, they focus on how to “plan and design transportation or hydraulic systems and structures, following construction and government standards, using design software and drawing tools” (www.job-descriptions.careerplanner.com). In order to ensure that the completed projects' reliability is up to par, civil engineers have to take into account environmental factors such as weather and apply their knowledge of geothermal physics. This career also requires individuals to have a solid background on chemistry, as the various materials used for construction each have their own unique...
“Sheltered as we are by Earth's atmosphere and magnetic field, which deflect lethal radiation from space, we are like coddled children who have never ventured into a tough neighborhood” (Folger 2). Humans have been fascinated with space since the beginning of our time. Just like children and rough neighborhoods, we have tackled obstacle over obstacle to make it home again. In the end, we have a better knowledge and strength than before. The future of space exploration can assist us in answering the everlasting question of how the universe came to be. The more we explore the infinite galaxies, the more we can scientifically discover and create new technologies as science advances. As we continue to discover, we can create new fields and occupations for aspiring young students like myself.
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.
Soil mechanics studies are the most related studies in Geotechnical Engineering to geology. It is analyzing the site conditions and the soil properties. Many soil properties need to be checked like the Atterberg Limits, which is the shrinkage limit. This indicates how much would the soil shrink because of weather and water limits.
Geotechnical Engineering covers the engineering properties of soils, the fundamentals of soil mechanics, and the application of geotechnical data and fundamentals to the design of foundation elements, earth-retaining structures, excavations, earth embankments and highway pavements.
