Robotic Mission vs Manned Mission Essay Example for Free

Robotic Mission vs Manned Mission EssayIt is my opinion that if given a choice between a golemic and a manned spot based exploration, it is better to execute a robotic mission. It is non worth the cost and risk for humans to simply explore shoes, except when the goal is specifically colonization. First, a manned mission would be much more technically complicated than a robotic one outweighing any incremental benefit resulting from a human presence. Second, the financial cost of manned missions to overcome the complications is not worth the projected costs. Third, funding robotic missions are indirect investments in aiding the reliable human condition.That is, the cost saving from robot missions could help relieve true issues here on earth. Lastly, pushing the boundaries of the unknown will al fashions be fascinating to humans, but we would be pushing current human boundaries to explore much further past the moon, with our current technology. Advancements in robot technolog y can allow us to take the next musical note in forward-looking space missions. Some would argue the opposite some would say that manned missions are essential to quench our curiosity and thirst for breakthrough the unknown, our desperate search for answers slightly the universe, and to find life beyond our planet. on that point are specific advantages to robotic exploration over human space missions. Space is a dangerous place for humans in many ways there are many factors working against long term human space travel. There is harsh radiation, zero gravity and the element of time to consider. Radiation, in form of cosmic rays (high energy particles) and other high-energy radiation emitted from our sun, breaks down DNA in our bodies (0), track downs to major complications, and poses the largest threat to human space travel.Extended zero gravity exposure leads to bone destiny loss and weakened organs because our physiology evolved having gravity. Time is also a factor against h uman space travel we simply cannot go fast enough and live long enough to make it. If we went 123,000 mph with current plasma engines (1) to the closest star, Proxima Centauri 4. 22 light years away (2), it would take 23 thousands years (2. 1). We cant live that long but robots could possibly go faster and need no protection from anything except sensitive equipment.Robots dont need to come back, they have no families and we can build unsanded ones. As questions are asked about the cosmos we develop new-fashioned detectors, telescopes, and probes to answer those questions safely, quickly, and with accuracy. Human space missions are extremely expensive, unsafe, and inefficient(3) compared to robotic ones. A manned mission would or so likely involve advanced life support systems, ample social interaction that means more people, food, oxygen, radiation protection, constant exercise, etc. with all systems organism mostly self-sustaining or replenishing.This is all equals to weight, c ost, time, and research. Also, the effects of zero-gravity and cosmic radiation have not been studied in depth and the long term exposure, could be detrimental(4). Also, the effects on the mind, in the long term, we know little about. (5) Constant isolation and confinement could drive any crew mad. (5. 1) We currently dont even have spacesuits that protect against radiation. (6) Dennis Bushnell, NASA Langleys chief scientist said, Whats affordable is not safe whats safe is not affordable. (7).A robotic mission would not encounter any of these problems and risks. The space shuttle had a price tag of about $450 million per mission and today unmanned payload cost about $12,000 per pound. (8) Most of this cost is associated with the fuel it takes to escape Earths orbit which is burned upon take off. The less weight expended the less fuel is required for takeoff, hence saving money to make it worth these endeavors. Assuming we do not colonise the location we plan on exploring, we would want our fellow space explorers to draw home to their families safely.This would require a mission plan home, this is more than one mission, an increase in cost and preparation, making a returning virtually impossible. (8. 1) Robotic space missions could directly address and change human conditions on Earth. The possibilities of immediate results on Earth are enticing, new technologies found through the research of problems encountered could lead to advanced propulsion technologies that could give us more efficient methods of travel here on Earth and possibly end our use of fossil fuels. Reaching and exploring asteroids could lead the way to learning how to divert one here on Earth(9).Possible colonization of new worlds can first be explored by robots, giving us an understanding of our true environment and helps us expand, as the human race not any specific nation or country but for humanness as a whole. Finding new resources from asteroids, moons, and worlds in our solar system c ould give us a new era of economic stimulus, growth, and hopefully peace. By 2030 we human on Earth will be consuming the resources of two planets annually (10), this is a scary thought and we must prepare for the possibility of expanding our horizons to the new frontier, united as one people for the common good.Some opposing cases have been argued that it is essential for manned missions to be funded. It is very possible for us to pass off Mars in one month (11) with a proposed 123,000 MPH plasma engine. This makes it imperative to do so immediately. With less and less standing in our way to colonizing our solar system, we must see these new frontiers with our eyes. New technologies researched for the survival of colonies in space, could bring many positive effects on Earth, such as closed-loop sustainable habitats would give the poor around the world, enough food. 12) This would not be possible, if we sent robots, since they dont eat. The necessity for manned missions could inadv ertently allow us to set off new technologies that will, assuredly help us on Earth. There even is the possibility of a one-way journey for a single candidate to colonize Mars. (13) This would reduce risk, cost, and the lives of other potential settlers. Since, there is no longer the competition of nations to reach space, like the space-race between USA and Russia, but today we work together, deal a club of developers. (14) In conclusion, I feel that a robotic mission is the way to explore space. The cost, risk, and benefits gained from a manned mission are just not worth it, when compared to a robotic one. Although, the possibility of many technologies arising from the research aimed toward at solving current hurdles of successful manned missions, we should not to bear the risks associated with them since, robots are generation of ourselves.
