Obstacles and Solutions for Human Travel and Exploration of Mars Man is not destined to stand idle in the face of new frontiers and undiscovered fortunes. Since the beginning of time, man has risked nothing short of his own life to step beyond dreams and achieve the reality of the new and undiscovered. With the need to find these new corners of the universe, new technologies must be achieved giving man not only the abilities to overcome the impossible but the opportunity to better understand man himself. The conquest of Mars is a necessary step to exponentially leap man’s knowledge into new realms of understanding. The conquest of Mars is no longer an option but a necessity. I have been tasked today to present to my audience the obstacles and solutions associated with human interplanetary travel with respect to Mars. While many current fuel and propulsions systems are purely hypothetical, the idea to propel is basically the same. The principle is based on Newton’s Third Law of Motion: For every action, there is an equal and opposite reaction. As propellant is expelled from the spacecraft, a reactionary force is acted upon the spacecraft creating movement. This can be done in many forms including chemical propellant, electricity, nuclear, and solar sails. Chemical propulsion systems are the current propulsion systems of choice in the current world’s space programs. Chemical propulsion systems contain a fuel source and oxidizing agent that are mixed and burned in a combustion chamber. As explained in Living Off the Land in Space, “The energy is released as new chemical bonds are formed in the ‘burning’ process. Channeling the energetic reaction products outward from the vehicle using a directional nozzle produces thrust (Matloff, Johnson, and Bangs 29-40).” Chemical propulsions continue to dominate the current preferred method of space travel and…...

...on a beat instead of doing paper work while sitting in the office. They frequently put off the job or do it inadequately which results in unclear and ambiguous reports which cause the police department to lose court cases. Another problem is that the captain is finding it difficult to figure out the possible ways to motivate them to do the paper work effectively and efficiently. There are various problems related to the employee motivation, ability of officers to perform task, lack of role perception and different situational factors. Question # 2 Use the mars model of individual behaviour and performance to diagnose the possible causes of the unacceptable behaviour? Answer- According to the MARS model of individual behaviour there are four factors that directly influence voluntary individual behaviour and performance. Those factors are Motivation, Ability, Role perceptions and Situational factors. We can use the mars model to diagnose the causes responsible for different problems in the given scenario. The causes are as follows - 1. Lack of motivation – Motivation is the force within the person that affects his or her direction, intensity and persistence of voluntary behaviour. As the captain has stated in the scenario that he is facing problem to find ways to motivate the employees. He doesn’t have any financial rewards at his disposal and since the nature of job is very boring and none of the employees find it interesting. It clearly shows that there is a lack of......

...“Mars” Physical Science April 9, 2012 When a person thinks of Mars he may think of many wonders. Some dream of traveling Mars while others simply wonders if there is life on Mars. I will talk about both dreaming and life on Mars, but first I would like to talk about the history of Mars. In 1968, NASA struggled to get the Apollo program back on track in the wake of the devastating launch pad fire on January 27, 1967, that had taken the lives of astronauts Gus Grissom, Edward White, and Roger Chaffee. While the nation awaited the resumption of the race to the moon, NASA scientist quietly continued their work on the Mars exploration program. At the time, planetary scientists were still grappling with the surprising results of Mariner 4 – a small pile of photographs of a desolate, crater-pocked world that seemed incapable of supporting life. Mariner 9 would complicate the picture, revealing an active planet, with volcanoes, canyons, and channels apparently carved by catastrophic floods. With those discoveries, the prospects for finding life on Mars – or at least evidence of ancient life – would rise again. But in 1968, Mariner 9 was still three years away. NASA’s decision to launch a mission to search for life on Mars was made at a time when few believed there was any life to be found. The Greeks named the planet after Ares, the god of war. The Romans later renamed it after their god of war: Mars. Little more was learned about Mars until the Renaissance, which marked the......

Mars Rover

...Cody Nitz Mars Rovers In the summer of 2003 we sent two rovers to Mars. These rovers where sent to Mars to give NASA a better understanding of the climate and water on Mars. With the technology that the Mars Rovers had it was like we were sending up two geologists. Spirit was the first rover to be sent off to Mars and it left June 10th, 2003 and landed January 3rd, 2004. It would be followed by Opportunity which was sent off on July 7th, 2003 and landed January 24th, 2004. NASA’s original goal for the rovers was very easy. They just wanted them to travel 40 meters in 1 day and to travel a total of 1 kilometer total. These rovers did that and a whole lot more and are currently still going. The design of these rovers came from the basic design of the 1997 Mars Pathfinder Mission. The rovers are identical they have 6 wheels and good suspension for driving over some harsh Mars surfaces. It has solar panels for its energy and also has radioisotope heater units for when the rover does not get a lot of sunlight. Each rover weighs 174 kilograms, is 1.6 meters long, and is 1.5 meters tall. The rovers also had a lot of heavy duty airbags for landing. These were very necessary because if any little piece broke it could affect the whole mission. The rovers also included different tools that would study the rocks and the surface of Mars to decide if there had ever been water on the planet. These tools consisted of a panoramic camera that helped the scientist from......

Mars

...Mars is not a habitable planet. If it was going to be habitable, there would have to be lots of changes to be made on Mars for anything or anyone to survive. Mars is a very cold place, about -23 degress C. For this reason neither organisms nor humans would be able to survive in this type of temperature. Penguins and polar bears would be able to live there due to the freezing weather. There is a thin atmosphere of carbon dioxide which would make it difficult to survive without being able to breath. In order to create oxygen, plants would need to be produced. The surface on Mars is rocky, so flattening the surface would need to happen first. Then creating a dome just to grow plants would be necessary. Once the plants have grown, I would remove the dome so the plants could create and release oxygen throughout Mars. More domes would need to be built to produce more oxygen needed for survival. With more oxygen being in the air, organisms would be able to survive on Mars. With Mars being so cold it made things even more difficult to survive. The freezing temperatures make it virtually impossible for plants, organisms, and humans to survive. Without water, survival is also impossible; if Mars was closer to the Sun, the frozen ice would be able to melt and then create water for the living organisms. Before human beings could actually create homes on Mars lots of big changes would need to be done. People think they can just wear a spacesuit and be fine but then......

Mission to Mars

...The Mission to Mars Project Signature Assignment Submitted to: Dr. Archer 06/28/2013 Abstract The purpose of this paper is to describe what the Mission to Mars Project and understand how they plan on surviving accordingly and what they plan to accomplish. The Mission to Mars project is a huge exploration venture for man-kind and can possibly cause a paradigm shift in our world as we know it today. I will describe the Mission exactly as it planned and many flaws that come with their plans. NASA has been defunded so this mission has been privatized by a nonprofit organization (Mission One). Mission One is seeking individuals to volunteer for their mission to Mars. The individuals they choose for the mission will have to expect to live on Mars and colonize the red planet. Most of their plans are just theory and I will research more of their plans like growing vegetation, using solar power, and survival. Introduction to “The Mission to Mars” Project Many great men and women have been able to experience the glory beyond our atmosphere. Retired NASA astronaut, Frank Borman, was one of those great men. Borman was one of the first 24 individuals to fly around the moon. Borman is a modern explorer, beyond the constraints of the seas, or land, Borman was able to reach new heights. This great explorer once said, “Exploration really is the essence of the human spirit, and to pause, to falter, to turn our......

Mars

... After numerous hours of research on the colonization of the planet Mars we have collected five real life hurdles that could be a threat to sustaining life on a planet other than earth. This group only contains two people. I Josh Watson, and my wife Lesley Watson. We have both teamed up and have done separate research on this topic and combined our information together to compare and contrast. The first major issue would be Terra forming. Terra forming literally means “Earth Shaping”. To colonize Mars we would need to terra form Mars into a planet comparable to earth. Yes Mars has an atmosphere with winds, clouds, seasons and days that are 24 hours long, but Mars has no magnetic field, thus resulting in lethal doses of radiation to humans. There has been evidence that suggests that the remains of polar ice caps have a magnetic field and are safe from radiation. If nothing else works then we would be limited to those areas. It might be possible to turn the Carbon Dioxide rich air into oxygen just like plants and trees do on earth but there would still be major issues with the planet not having a shield for protection. The cost of a trip to planet Mars is another hurdle that gets in our way. NASA has the ability to build a vehicle to take astronauts to Mars, but due to Barrack Obama’s decision to cut the Constellation program in 2010 it appears that any trips to Mars would have to be paid for by funds available in the private sector without......

Colonizing Mars

...COLONONIZING MARS AND BUILDING SMART HOTELS Recently, space tourism and space colonization topics on the agenda. The works of NASA has reached so far and today, “life in the Mars” is not a dream. With these technological developments in space science, people had started thinking about going Mars trips. So many businessmen already spent so much money on space tourism. In this case, what comes to mind is, if today, it is possible to travel to Mars, why would not be impossible not to live there. As young entrepreneurs, our company aims to build smart hotels and houses on Mars with the help of the reliable and safe transformation that we supply. We thought that the world needs that kind of a company for two reasons: the natural structure will be disrupted in short time and moving in another planet will open new doors to reach other planets. According to the researches world’s natural situation is changing in a negative way because of the human intervention and these interventions are changing the natural structure. One of the most important changes is climate change and accordingly changes in the sea levels. In short time world can be under the water and people will need a new land to live. The other important factor is the possible effects of asteroids. These are not human based but emergency situations. If an asteroid hits the earth it creates an extreme force and will cause the extinction of many species. This is the reason that the world should have a back-up plan in......

Life on Mars

...There are several companies researching and exploring ideas on how to get to Mars. Space X is one of those companies they were founded in 2002. The Headquarters of Space X is located in Hawthorne, Ca. and they design, manufacture and launch advanced rockets and spacecraft’s. Space X, is short for Space Exploration Technologies Corporation, it is one of two private companies that NASA has contracted to transport cargo to the International Space Station. (Robertson, 2013) Space X can launch cargo from approximately 5 tons to 53 tons on their two rocket designs right now, cargo services are available on the Falcon 9 space craft for about $56.5 million dollars to sub orbit. If you need larger payload capabilities Space X also has the Falcon Heavy which is capable of carrying heavier payloads. As of right now 6.4 tons or less will cost $77.1 million dollars or for loads over 6.4 tons will cost approximately $135 million dollars. (SpaceX, 2014) Elon Musk is the CEO and Chief designer of Space X and he also co-founded PayPal services. “The key thing for me is to develop the technology to transport large numbers of people and cargo to Mars. That’s the ultimate awesome thing.” Musk envisages a colony with 80,000 people on the red planet. Musk believes he can get this under way in the next 10 to 20 years with the first manned mission to the Red Planet. The key is developing a reusable rocket to help keep cost down. (Coppinger, 2012) “Tickets to go to the Red Planet will cost about......

Mars

...Mars: The New Frontier ITT Technical Institute In 2023 an organization called Mars One plans to have a human settlement established on Mars. According to Mars One (2012), every two years after that they will send a new crew to join the settlement. Further, Mars One states, “The crew will emigrate to Mars. They will spend the rest of their lives living and working on Mars. While sustaining life on Mars isn’t trivial, it is much easier and safer than bringing the crew back to Earth” (para. 2), due to not having the resources needed at this time to bring them back safely. Mars One (2012) “will provide the first and subsequent water, food, and oxygen by mining sources from Mars’ soil and atmosphere” (para. 2). These people volunteering for this mission are making one of the biggest sacrifices possible for advancement in knowledge and science. Mars One (2012) stated, “All components required to complete the mission can currently be built by existing suppliers” (para.3). Mars One estimates the cost to send the first four people to be at six billion US dollars. That cost is for hardware combined, plus the operational expenditures, plus margins. For every next mission Mars One estimates the cost at four billion US dollars. Mars One (2012) “To finance this mission Mars One will create an international media event around the project. They will share their experiences as they build their new homes, conduct experiments, and explore. The mission itself will provide scientific and......

The History of Mars

...Mars and its Future.           On November 28, 1964, the Mariner 4 spacecraft was launched from Cape Canaveral Air Force Station. After 7 ½ months of flight, Mariner 4 reached the surface of mars and took the first pictures of the Martian planet. Since then we have launched more than 40 spacecrafts to mars, from orbiters that fly by the atmosphere to landers that have been on the surface of Mars (“10 things to know about mars”) . Today we still continue to progressively learn and to explore the famous red planet.           Mars is the same age as Earth. The whole solar system and everything in it was formed the same time, about 4.56 billion years ago. One of the greatest scientific questions is if there's life on Mars. Since scientists know that Earth and Mars both experienced similar weather conditions in early history, and life eventually happened on Earth. Therefore life may have begun on Mars too. The big question is if life did start their, then how did it die out? Maybe there is still life on Mars, and it’s buried underground where conditions may be less hostile. The only way to answers all these questions is to explore Mars.         Scientist call comparisons between Earth and Mars analogs. Scientists say that even though, the two planets are mostly different when it comes to the atmosphere, temperature, size, and the geologic processes on the two planets. Surprisingly there are similarities between the two planets, also. An example is, on Mars there are volcanoes,......

Mars

...ar Mars By: Amanda Baker The discovery of Mars is not credited to a single individual, but rather a multitude of astronomers and observers that range from the early Egyptians to the Babylonians, Greeks, and Danish. In the earliest days of Mars observation, all that was known about it was that it appeared to be a fiery red and followed a strange loop in the sky, unlike any other. “The Babylonians studied astronomy as early as 400 BC, and developed advanced methods for predicting astronomical events such as eclipses. They made careful observations for their calendars and religious reasons, but never attempted to explain the phenomena they witnessed. The Babylonians called Mars Nergal - the great hero, the king of conflicts. The Egyptians were the first to notice that the stars seem "fixed" and that the sun moves relative to the stars. They also noticed five bight objects in the sky (Mercury, Mars, Venus, Jupiter, and Saturn) that seemed to move in a similar manner. They called Mars Har Decher - the Red One. Greeks called the planet Ares after their god of war, while the Romans called it Mars. Its sign is thought to be the shield and sword of Mars” (NASA, 2015). Mars is the fourth planet from the sun and referred to as the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. Mars has been known since prehistoric times, and of course, it has been extensively studied with ground-based observatories. But even......

Almaayta, Hassan Borg, Richard TMG610 Michael Buckley Date, 2015 Table of Contents Abstract 3 Introduction 3 Methodology 4 Background 4 Dimensions of culture 5 Case one: Sweden 6 Sweden and its business culture 6 Swedes differ from the general view on culture 6 Case study: Slussen 6 Case two: Jordan 7 About Jordan 7 Business Culture in Jordan 8 Case study: Casino Project in Dead Sea 8 Consequences of stopping the project 9 Conclusion 9 References 10 Abstract Along with the huge trend toward globalization, the world economic get more united. Still there are several obstacles slow down this trend, or it seems to be that. One of these obstacles is the culture. Through the following discussion, the main idea is to show that culture is not an obstacle; rather that globalization should deal with it as a key customer. Moreover, nations, countries, states, and people should change their vision to start deal with globalization as a project not as a goal. This project should have several goals. These goals should be in line with customers’ requirements. Therefore, the customer who is the local culture will accept and support this project. Introduction Culture is an umbrella term for patterns of thoughts, emotions, and ways to act which mankind lives by. Everywhere we go outside our own land border one would face a new culture that somehow differs in a way from the one used to, regardless if it concerns a......

Race to Mars

...Tim Jones Rita Kiry Composition 6/23/2015 Race to Mars The race to Mars has many competitors and is a long way from being a reality, but there are many technological advancements being made to get to Mars. The list of companies range from large known aerospace companies to small aerospace companies that have been around for only a short time to nonprofit companies that only want to manage the trip. Even though there is many companies striving to be the first to put a man on mars. They all will have the same hurdles to jump and space to travel through to get there. Mars has always been a wonderment to mankind. Human eyes have looked in its direction since nearly the 17th century, but it wasn’t till 1965 that a satellite was close enough to get decent pictures of its surface. The only thing those pictures did was raise more questions than answers (Lockheed Martin). The only thing left to do was to put something or someone on its surface. Lockheed Martin built the first orbiter that took pictures as well as the first two landers to touch the surface of Mars. Lockheed participated in the Mars Odyssey mission by building the orbiter in which the mission was named. The Odyssey later became the main means of communication for NASA to the rovers on the surface of Mars. Lockheed has no plans to quit being in the cutting edge of sending satellites to Mars. NASA started the race to Mars with the launch of Mariner 3 on November 5, 196 which was the first flyby......
