Robotic Mission vs Manned Mission Essay Example for Free

Robotic Mission vs Manned Mission Essay It is my opinion that if given a choice between a robotic and a manned space based exploration, it is better to execute a robotic mission. It is not worth the cost and risk for humans to simply explore space, 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 current human condition. That is, the cost saving from robot missions could help relieve current issues here on earth. Lastly, pushing the boundaries of the unknown will always 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 technology can allow us to take the next step in advanced space missions. Some would argue the opposite; some would say that manned missions are essential to quench our curiosity and thirst for uncovering the unknown, our desperate search for answers about the universe, and to find life beyond our planet. There 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), leads 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 human 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 don’t need to come back, they have no families and we can build new ones. As questions are asked about the cosmos we develop new 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 most likely involve advanced life support systems, ample social interaction that means more people, food, oxygen, radiation protection, constant exercise, etc. with all systems being mostly self-sustaining or replenishing. This is all equals to weight, cost, 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 don’t even have spacesuits that protect against radiation. (6) Dennis Bushnell, NASA Langley’s chief scientist said, â€Å"What’s affordable is not safe; what’s 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 Earth’s orbit which is burned upon take off. The less weight expended the less fuel is required for takeoff, thus saving money to make it worth these endeavors. Assuming we do not colonize the location we plan on exploring, we would want our fellow space explorers to return 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 humankind as a whole. Finding new resources from asteroids, moons, and worlds in our solar system could 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 reach 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 don’t eat. The necessity for manned missions could inadvertently allow us to discover 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, â€Å"Like 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 extension of ourselves.

The Dysfunctional Family Essay

In a family with one rebellious child, the other children have to â€Å"walk on egg shells† to avoid the wrath of their parents. Going beyond mere disagreement, an intense schism between family members regarding religion or ideology Lack of empathy, understanding, and sensitivity towards certain family members, while expressing extreme empathy towards one or more members (or even pets) who have real or perceived â€Å"special needs†. In other words, one family member continuously receives far more than he or she deserves, while another is marginalized Extremes in conflict (either too much fighting or insufficient peaceful arguing between family members Unequal or unfair treatment of one or more family members due to their birth order, gender, age, family role (mother, etc.), abilities, race, caste, etc. (may include frequent appeasement of one member at the expense of others, or an uneven enforcement of rules Denial (refusal to acknowledge abusive behavior, possibly bel ieving that the situation is normal or even beneficial; also known as the â€Å"elephant in the room.†) Unhealthy parenting signs: Giving â€Å"mixed messages† by having a dual system of values (i.e. one set for the outside world, another when in private, or teaching divergent values to each child) Stifled speech (children not allowed to dissent or question authority) Denial of an â€Å"inner life† (children are not allowed to develop their own value systems) Being under- or over-protective Apathy â€Å"I don’t care!† Belittling â€Å"You can’t do anything right!† Unrealistic expectations Ridicule Bitterness (regardless of what is said, using a bitter tone of voice) The â€Å"know-it-all† (has no need to obtain child’s side of the story when accusing, or listen to child’s opinions on matters which greatly impact them) Either being a miser (â€Å"scrooge†) in totality or selectively allowing children’s needs to go unmet (e.g. father will not buy a bicycle for his son because he wants to save money for retirement or â€Å"something important†) Dysfunctional parenting styles: Perfectionist (fixating on order, prestige, power, and/or perfect appearances, while preventing their child from failing at anything) Dogmatic or cult-like (harsh and inflexible discipline, with children not allowed, within reason, to dissent, question authority, or develop their own value system) â€Å"The politician† (a parent who repeatedly makes or agrees to children’s promises while having little to no intention of keeping them) Dynamics: Parents vs. kids (generation gap or culture shock dysfunction) The balkanized family (named after the three-way war in the Balkans where alliances shift back and forth) Children growing up in a dysfunctional family have been known to adopt one or more of these six basic roles: The Good Child (also known as the Hero): a child who assumes the parental role. The Problem Child or Rebel (also known as the Scapegoat): the child who is blamed for most problems related to the family’s dysfunction, despite often being the only emotionally stable one in the family. The Caretaker: the one who takes responsibility for the emotional well-being of the family. The Lost Child: the inconspicuous, quiet one, whose needs are usually ignored or hidden. The Mascot: uses comedy to divert attention away from the increasingly dysfunctional family system. The Mastermind: the opportunist who capitalizes on the other family members’ faults to get whatever he or she wants. Often the object of appeasement by grown-ups. Effects on children Children of dysfunctional families, either at the time, or as they grow older, may also: Lack the ability to be playful, or childlike, and may â€Å"grow up too fast†; conversely they may grow up too slowly, or be in a mixed mode (e.g. well-behaved, but unable to care for themselves) Have moderate to severe mental health issues, including possible depression, anxiety, and suicidal thoughts Become addicted to smoking, alcohol, and/or drugs, especially if parents or friends have done the same Bully or harass others, or be an easy victim thereof (possibly taking a dual role in different  settings) Be in denial regarding the severity of the family’s situation Have mixed feelings of love–hate towards certain family members Become a sex offender, possibly including pedophilia. Have difficulty forming healthy relationships within their peer group (usually due to shyness or a personality disorder) Spend an inordinate amount of time alone watching television, playing video games, surfing the Internet, listening to music, and other activities which lack in-person social interaction Feel angry, anxious, depressed, isolated from others, or unlovable Have a speech disorder (related to emotional abuse) Distrust others or even have paranoia Become a juvenile delinquent and turn to a life of crime (with or without dropping out of school), and possibly become a gang member as well Struggle academically at school or academic performance declines unexpectedly Have low self-esteem or a poor self image with difficulty expressing emotions Rebel against parental authority, or conversely, uphold their family’s values in the face of peer pressure, or even try to take an impossible â€Å"middle ground† that pleases no one Think only of themselves to make up the difference of their childhoods (as they are still learning the balance of self-love) Have little self-discipline when parents are not around, such as compulsive spending, procrastinating too close to deadlines, etc. (unfamiliar and seemingly lax â€Å"real-world† consequences vs. familiar parental consequences) Find an (often abusive) spouse or partner at a young age, and/or run away from home Become pregnant and/or a parent of illegitimate children Be at risk of becoming poor or homeless, even if the family is already wealthy or middle-class Have auto-destructive or potentially self-damaging behaviors Join a cult to find the acceptance they never had at home, or at a minimum, have differing philosophical/religious beliefs from what they were previously taught Strive (as young adults) to live far away from particular family members or the family as a whole Perpetuate dysfunctional behaviors in other relationships (especially their own children)

Personal Code Of Ethics By Meredith Keck - 777 Words

Personal Code of Ethics Meredith Keck University of the Incarnate Word: Communications in Organizations 27 January 2017 Introduction Leaders are expected to act consistently with their vision and the values they advocate to their team. If a leader’s words or actions are contrary to the values they expect in others, they will be faced with cynicism and contempt. Followers expect their leader to act in their best interests, putting their welfare before their own. An ethical leader is honest, open and truthful to their followers. When leaders lose this trust, their followers will quickly disregard them. Part I Knowledge, integrity, empathy, patience, and love are at the core of my ethos. These traits shape my character, nature,†¦show more content†¦Many higher ranking leaders may unintentionally make them feel disregarded because of this. When a new Airman joins my team it can take them months to open up and begin expressing their ideas. However, change is on the horizon- a year ago our Medical Wing developed an ‘Innovation Center’. All ranks are encouraged to attend a nine day Innovation Center course where they can openly share their ideas to improve our organization. Providers sit with technicians and Generals rub elbows with Airmen to learn Lean management and work together to develop improvement strategies and plans. Part II As a leader, I am committed to creating an open, welcoming environment that respects diversity and creative thinking; inspiring personal and professional growth. I value all individualities and viewpoints equally. My ethics are the same for every one of my followers, regardless of age, ethnicity, culture, gender, sexual orientation, or religion. By removing any stigmas or barriers, we strengthen the unity between us, enabling us to succeed individually and as a whole. I encourage my team to be open with me on all accounts. When they share personal matters with me, I keep them confidential. The trust that we have built within my team is incredible, and it is not something that I take lightly. I am devoted to keeping this trust within my team by staying true to my
