Space Exploration Methods

Amazing Essays
The future of space exploration starts today with the Space Launch System. Soon we will be able to go farther and faster than ever before to explore Mars and everything beyond. There are many difficult choices to be made before this is possible. We must choose a transportation method for the crew to travel these vast distances. SEP-Chem and the Hybrid Method are the two most promising methods. We must also be able to use Mars’s natural resources to our advantage and explore new ways of getting to other planets by using gravity with current propulsion technology. The SEP-Chem and Hybrid Method are similar in their initial stages of deployment. With the timeline to send humans to Mars and its moons in the mid 2030’s regardless of which system …show more content…
For humans to stay healthy it is recommended that, “an adult male needs about 3 liters per day while an adult female needs about 2.2 liters per day” according to the United States Geological survey. Mars missions will require a lot of water for each crew member to stay healthy. We will need to bring all of our water with us or find a way to extract it from the Martian land. In 2015 NASA announced an important discovery about running water on the surface of Mars. Liquid water flows according to NASA, appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times”. Hydrated salts lowered the freezing point of the water essentially creating brine making it possible for water to flow on the surface of Mars. Future Mars missions could greatly benefit from this discovery with a source of water confirmed on Mars, we can collect it for studying and eventually consumption. Once we have examined the Brine and determined it safe for human consumption, we can begin a desalination process to create drinking water. By tapping into this water source we would no longer have to drink so much water for a single mission, which would lower the payload weight at launch ultimately saving money for other …show more content…
One of the most recent examples of this is the New Horizons probe’s journey to Pluto and beyond. The team used the gravity well of the gas giant Jupiter to speed the probe up so it would fly by Pluto in 2015. Another more dramatic example of using the gravity assists maneuver was the Apollo 13 lunar mission. Apollo 13 was badly damaged by an explosion of the oxygen tanks which crippled the craft rendering the command module useless and with it the engines. Apollo 13 used the Moon’s gravity to slingshot themselves around for a return trajectory to Earth with the help of the Lunar Lander’s

    It sounds too funny, we study in the atmosphere of Titan, but we still decide to use lander. According to the different layers of atmosphere, we need to know and understand the each layer’s compositions. Therefore, we start to work on the lander because lander can go down through the whole atmospheric layers and land on the surface of Titan for collecting evidence, which can help us to find weather the origin of methane comes from the underground or not. In January 2005, the Huygens probe landed on Titan. It is a good successful example to land on Titan and it also transmitted the data back to Earth before its batteries died.…

    These moon missions may also be used as a base of operations where humans will learn how to replenish essential supplies. “NASA has an exciting new vision of future space flight - the return of humans to the moon by 2020 in preparation for visits to Mars and possibly beyond.” (Schlager,NP) Those skills are essential to the future expansion of human presence into deeper space. The Constellation project also has objectives. Although humans have visited the moon before, it still harbors mysteries including the investigation of water ice near it’s poles. Future missions are also being planned to observe the Sun, venus, and even Jupiter.…

    Space colonization would be our century’s version of the moon landing but a thousand times more spectacular. Imagine living on a planet light years away. To just get there, we would need an engine able to harness an unimaginable amount of energy, radiation shields, a spacecraft able to create a biosphere to sustain crop growth, and a way to recycle water. The invention of these items would alone be quite a phenomenon. To combine all these inventions would be a plethora of innovation.…

    The report outlined NASA’s plan for future Mars exploration as well as NASA’s goal of sending men and women to Mars in the 2030’s, “not just to visit, but to stay” (NASA 7, 29). In this report, the future missions were broken up into three categories: Earth Reliant, Proving Ground, and Earth Independent (NASA 7). The organization also identified three key challenges that must be overcome in order to have a manned Mars mission. Those challenges include transportation, working in space, and staying healthy (NASA 29-31). Each stage in the plan will systematically address these challenges in a way that will produce reliable…

    Mars is a prime example of any space missions to other planets because it is the planet we have tried to observe the most. One of the spacecraft’s, Mariner 4, missions was to carry out the first flybys of Mars. It collected the first close-up photographs of the planet and had a small tape recorder on it as well. It showed us craters on Mars and while in Mars’ solar orbit it also taught us about Mars’ solar wind environment; teaching us about the magnetic field and atmosphere of the planet. There is a current mission happening called MAVEN that hopes to learn more about how fast atmospheric gases are being lost to space today, leading to knowledge about what happened in the past.…

    On November 26, 2011 NASA launched a robotic space probe mission to Mars, called “Mars Science Laboratory”. This mission successfully landed Curiosity rover in Mars on August 6, 2012 (Space). The objectives of this mission included investigating Mars’ habitability, studying its climate, and collecting data for a manned mission to mars in the future. The Mars Science Laboratory mission is an incredible mission that will change humanity forever. The first reason is being able to ensure the survival of our species (Orwig).…

    Robots will be sent first, then humans to Mars. The Mars 2020 rover will help NASA understand the current weather, winds, radiation, and dust environment. Also, it will demonstrate technologies that will help humans once there. The moon has radiation too when Americans went there, but a good argument is made with radiation with more time on Mars. Many astronauts are willing to assume the risks of Mars Mission, so they know the costs of this greater good.…

    It meant that people could survive in space and there was a possibility of making more discoveries. When the Soviets were able to the beat the US to a common goal when they were so close to accomplishing it themselves it logically lead to some tension and made the US more focussed on completing the next step in space history. When President Kennedy announced that the US would reach the moon before the Soviets it showed that the US wanted to win the Space Race and that they were going to do anything to redeem themselves after not being able to get the first person in space. Ultimately Vostok 1 made the US want to have a larger breakthrough than the Soviets. This lead to the start of the Apollo Program.…

    With the vastness of space that contains humanity 's own planet plus billions of others there is almost a grantee of life. As for life it may not to far away the Goldilocks zone still holds a number of discoveries that have not been found. As time advances so does technology that is a given, humanity will continue to advance. It will become smarter, being able to create device able to find heat signal of planets to possibly observe life, or be able to launch space telescope so massive that they can observe planets with potential life with ease, and not to forget to mention one day for certain there will be a way to travel to these planets. Even now organizations such as NASA are still researching the life that exist in space.…
