The History and Legacy of Project Mercury

The History and Legacy of Project Mercury For people who were living in the 1950s and 1960s, the Space Race was an exciting time when people were venturing out from Earths surface and heading to the Moon, and hopefully beyond. It officially began when the Soviet Union beat the U.S. into space with the Sputnik mission in 1957 and with the first man into orbit in 1961. The U.S. scrambled to catch up, and the first human crews went to space as part of the Mercury program. The program goals were fairly simple, although the missions were quite challenging. Mission aims were to orbit a person in a spacecraft around Earth,  investigate a humans ability to function in space, and to recover both astronaut and spacecraft safely. It was a formidable challenge and it affected the scientific, technological, and educational establishments of both the U.S. and the Soviets. The Origins of Space Travel and the Mercury Program While the Space Race got started in 1957, it had roots much earlier in history. No one is exactly sure when humans first dreamed of space travel. Perhaps it began when  Johannes Kepler  wrote and published his  book Somnium. However, it wasnt until the middle of the 20th century that technology developed to the point where people could actually transform ideas about flight and rockets into hardware to achieve space flight. Initiated in 1958, completed in 1963, Project Mercury became the United Statess first man-in-space program. Creating the Mercury Missions After setting goals for the project, the newly formed NASA adopted guidelines for the technology that would be used in the space launch systems and crew capsules. The agency mandated that (wherever it was practical), existing technology and off-the-shelf equipment should be used. Engineers were required to take the simplest and most reliable approaches to system design. This meant that existing rockets would be used to take the capsules into orbit. Those rockets were based on captured designs from the Germans, who had designed and deployed them during World War II.   Finally, the agency set up a progressive and logical test program for the missions. The spacecraft had to be built tough enough to withstand a great deal of wear and tear during launch, flight, and return. It also had to have a reliable launch-escape system to separate the spacecraft and its crew from the launch vehicle in case of impending failure. This meant that the pilot had to have manual control of the craft, the spacecraft had to have a retrorocket system capable of reliably providing the necessary impulse to bring the spacecraft out of orbit, and its design would allow it to use drag braking for re-entry. The spacecraft also had to be able to withstand a water landing because, unlike the Russians, NASA planned to splash its capsules down in the ocean.   Although most of this was accomplished with off-the-shelf equipment or through the direct application of existing technology, two new technologies had to be developed. Those were an automatic blood-pressure measuring system for use in flight, and instruments to sense the partial pressures of oxygen and carbon dioxide in the oxygen atmosphere of the cabin and space suits. Mercurys Astronauts The Mercury program leaders decided that the military services would provide the pilots for this new endeavor. After screening more than 500 service records of test and fighter pilots in early 1959, 110 men were found that met the minimum standards. By the middle of April Americas first seven astronauts were selected, and they became known as the Mercury 7. They were Scott Carpenter,  L. Gordon Cooper,  John H. Glenn Jr.,  Virgil I. Gus Grissom,  Walter H. Wally Schirra Jr.,  Alan B. Shepard Jr., and  Donald K. Deke Slayton The Mercury Missions The Mercury Project consisted of several unmanned test missions as well as a number of missions taking pilots into space. The first one to fly was Freedom  7, carrying Alan B. Shepard into a suborbital flight,on May 5, 1961. He was followed by Virgil Grissom, who piloted the Liberty Bell 7 into a suborbital flight on July 21, 1961. The next Mercury mission flew on February 20, 1962, carrying John Glenn into a three-orbit flight aboard Friendship 7.  Following Glenns historic flight, astronaut Scott Carpenter rode Aurora 7 into orbit on May 24, 1962, followed by Wally Schirra aboard Sigma 7 on October 3, 1962. Schirras mission lasted six orbits. The final Mercury mission took Gordon Cooper into a 22-orbit track around Earth aboard Faith 7 on May 15-16, 1963. At the end of the Mercury era, with its technology proven, NASA prepared to move forward with the Gemini missions. These were planned as preparation for the Apollo missions to the Moon. The astronauts and ground teams for the Mercury missions proved that people could fly safely to space and return, and laid the groundwork for much of the technology and mission practices followed by NASA to this day.   Edited and updated by Carolyn Collins Petersen.

The Payroll and Personnel Cycle - Assignment Example many steps involved, the organization of time cards and distribution of salaried management; this must be handles for each department within the company. They also, must attend to the necessary taxes and make certain that those numbers are properly reported to the correct government agencies. They must update these reports as they go and incorporate and update ledgers. This process must be completed for each and every pay period within a company. The payroll and personnel cycle is one that, often, requires diligent monitoring because it is a point where fraudulent acts from within the company can occur. When auditing this portion of the accounting cycle they, primarily, focus upon finding verification that their account balances are accurate and â€Å"fairly stated† in accordance with current accepted accounting principles.(Arens, Elder, and Beasely 3) In order to avoid fraud and any misinterpretations it is suggested that those responsible for the information have proper sepa ration of duties, that numbers are confirmed multiple times, correct adherence to the use of appropriate documents, and regular, physical, control over all assets and records. Ideally, these â€Å"internal control† measures will help to prevent the possibility, let alone the success of fraud, within the payroll and personnel portion of the accounting cycle. (Arens, Elder, and Beasely 16) However, it has, also, been said that the cycles of accounting and the differentiation of steps is the product of the manual accounting process that has been practiced for decades, practices that require individuals to do the steps completely by hand, entering the amounts into journals or ledgers, practices that are presently obsolete.

As the essay discusses  the cycles of accounting and the differentiation of steps is the product of the manual accounting process that has been practiced for decades, practices that require individuals to do the steps completely by hand, entering the amounts into journals or ledgers, practices that are presently obsolete. Much of the purpose of the steps in the accounting cycle was invented to simplify the process for the people involved in performing them. These are simplifications that modern technology does not need. Today most companies use accounting software that is capable of calculating and organizing the numbers much more efficiently and simultaneously providing balances and adjustments.According to the study findings  not only is the software more expeditious, more efficient, and provides a lesser margin of human error, but it, also, meets the desires of many businesses to â€Å"Go Green.†Ã‚   Many of the software will allow businesses to engage in a â€Å"paper less accounting.†Ã‚   The transfer from human to software accounting is that the traditional payroll cycle is one with a great deal of paper documents, like paychecks, reports, and receipts, that are highly confidential; The paperless route allows for decreasing the likelihood that any unauthorized individuals could have access to private information they should not be privy to.  The movement towards more automation and technology within companies will increase, and accounting software may very well be the financial solution for maintaining and organizing company finances.

Reading the paper and answer question - Essay Example Traditional methods and materials have been replaced by modern means of nail connections and light wood frames. He further sees today’s carpenters as finishers of houses, rather than builders of houses. He begins by telling the readers about Henry Mitchell, his neighbor who has lived in the same house for 85 years. Henry Mitchell watches the writer renovate his house often. Each renovation watched by his neighbor reminds the writer of the original builder of his house one and a half centuries ago (Invention & Technology, 1999). The writer notes that before the 19th century, frame houses were built using large timbers. The constructors believed that sawing was a waste of materials and labor, so, through experienced workers, they only squared off logs to facilitate connection. This gave rise to the balloon frame. They introduced nails and lumber in mass production, giving further advantage to the balloon frame. The results were savings in man hours, less requirements in skills a nd a complete change in ways of building. The writer also notes that balloon frames are structurally and materially more efficient. Since no joint is of more significance than another, then the connection between each wood is efficient. This exemplifies modification of building practices progressively. Although the practices called for less labor, simplified connections and used light weight materials, they were limited because construction of houses never reached a fully automated level. Therefore, in as much as it was an innovation, it has remained resistant to change, to the surprise of many (Invention & Technology, 1999). The writer also believes that the American style of construction of houses was influenced by the Midwest, made up of the French, Amerindians, Europeans and Spaniards (Invention & Technology, 1999). The 19th century saw new houses rise in demand, occasioned by a change in wood technologies, and American settlers around the Mississippi at that time found new cult ures in building. The settlers built sawmills as one of their new enterprises, contributing to the millions of feet of lumber produced in the region. This denotes a change towards the new culture, because if the settlers had been close to a river, they would have used saw planks instead. The writer also believes the invention of balloon frame lies with the Chicagoans. This is because the balloon frame is among the City’s founding myths. It has also been mentioned as a contributing factor to the 1872 Chicago fire. It is believed that in 1833 when Chicago was a year old, Augustine Taylor, a carpenter from Connecticut, was requested to build many houses but his response was to invent balloon frames (Invention & Technology, 1999). In that year, wood was of variable quality and dimension. In the structure of a balloon frame, one joint may collapse due to poor quality wood, but the main structure will remain stable because of many redundant joints. Nevertheless, the openings left b y the collapsed joints would let in cold in cold weather. It was, therefore, suggested by Taylor that dimension lumber, since it reacts in different ways than wood plunks and timber, be selected by experienced carpenters. It would then be assembled into a building leaving allowance for contraction and expansion. With all the displayed experience, observers noted that Taylor must have worked with balloon frames before his arrival in

There are three pairs of questions below Article

There are three pairs of questions below - Article Example The Yoga of the Gita is founded on two major terms: ‘Vairagya’ and ‘Abhyasa’. While it may be difficult not to use â€Å"and† between the two closely related terms, the connector â€Å"and† should be used carefully because the two terms basically refer to the same thing. The two go hand in hand. An individual cannot practice ‘Vairagya’ in one day and practice ‘Abhyasa’ on another day. The two go together and are like the head and tail of a coin. Essentially, there is usually no time variation between the practice of ‘Vairagya’ and ‘Abhyasa’. People must be adept and skillful in ‘Vairagya’ and ‘Abhyasa’ simultaneously. While individuals have to be withdrawn, they must also be concentrated at the same time. This is reflected in non-attachment and steadfastness, which form the major principle in Yoga of Bhagavad-Gita. The ultimate meaning is that individuals must be very observant. A person must ever be cautious and is not supposed to forget this important virtue. â€Å"Pramada† or weakness is perceived to be a big mistake in a bid to perfect one’s soul. An individual needs to be an expert in connecting ‘Vairagya’ and ‘Abhyasa’. As the Gita tells us, the art of expertnesses in itself manifests Yoga, which is referred to as Yogah Karmasu Kausalam. Yoga is also the ability of an individual to present himself to daily life issues and to acclimatize to different scenarios. This is because according to Gita, each situation is a timeless incidence. Despite the fact that Bhagavad Gita is perceived to be an archaic text of yoga, it has limited coverage of practical yoga. The Gita conforms to Arjuna’s urge for divine assistance. Krishna provides solutions to Arjuna’s questions on ways to explore his internal holiness in order to take charge of his worldly mandates (Prakash, 2009). Yoga takes the form of Karma yoga, which is the service yoga, jnana yoga, which is a yoga that concerns knowledge, especially self-knowledge and finally, bhakti yoga, referring to the yoga of dedication or devotion to love. Bhakti yoga is the most important off all forms of yoga in the Gita. In the Gita, there are various forms of yoga that fundamentally refer to a single thing. The other forms yoga are all belong to bhakti-yoga. The divergence is only in the level of emphasis (Prakash, 2009). Bhakti-yoga is the perfection of all other forms of yoga and hence stands out as the most important form of yoga. Q2b. The following quotes form the main foundation of the principle of the doctrine of Conditioned Genesis: â€Å"When this is, that is; This arising, that arises; When this is not, that is not; This ceasing, that ceases† This principle of conditionality, relativity as well as interdependence clarifies the process of life from birth to death. It explains how life comes about, exists and progresses (Rahula, 1974, p. 53). According to the doctrine of Conditioned Genesis, life does not happen like a sequence of reactions but reflects a string of recurring events. Every element is conditioned and is conditioning at the same time. The doctrine of Conditioned Genesis is as such cyclical and not similar to a sequence of reactions. The doctrine of Conditioned Genesis holds that the notion of an abiding and eternal gist in man is a bogus belief and only a mere psychological projection. The assessment of the twelve elements of the doctrine enables

Business Communication - Essay Example First, Marge did not plan well for Jerry’s evaluation. Jerry is full of excitement about his evaluation, has thus prepared well, and planned his time well in a way that he arrives at the conference room five minutes earlier. As a good leader, Marge needed to do likewise and appear on time for Jerry’s evaluation, which would give both of them a chance to converse and come to an agreement before eleven o’clock. Marge is using her lagging behind schedule, her hectic morning, and a meeting ahead with an important client as an excuse to sit and evaluate Jerry in a proper manner. Her lack of planning brings about the miscommunication between her and jerry. Jerry even quotes her as â€Å"late again† to show that it is a habit. A second barrier to communication between Jerry and Marge is their conflicting goals. As a supervisor to Jerry, Marge retorts that if he rates Jerry anything beyond average, he may relax. She appreciates that Jerry is working hard, but she does not communicate this to him. Instead, she decides to give him this rating to make Jerry work harder and improve on his work. On the other hand, Jerry expectations are high and according to him, an above average or excellent is his rating. He needs an explanation as to why Marge rates her as average and refuses to sign the evaluation documents. Marge cannot explain her aim in rating Jerry in the average column and thus they fail to understand one another.
