Skylab :: essays research papers

Skylab Skylab was America's first experimental space station. Some of Skylab's program objectives were: To prove that humans could live and work in space for extended periods, and to expand our knowledge of solar astronomy well beyond Earth-based observations. Skylab made much use of Saturn and Apollo equipment. Through the use of a "dry" third stage of the Saturn V rocket, the station was completely made as a workshop area before launch. Crews visited Skylab and returned to earth in the Apollo spacecraft. THE FLIGHTS Skylab's 1st unmanned mission May 14, 1973 The station was launched into orbit by a Saturn V booster. Almost immediately, problems developed due to vibrations during lift-off. A critical meteoroid shield ripped off taking one of the craft's two solar panels with it; a piece of the shield wrapped around the other panel keeping it from deploying. Skylab was maneuvered so its Apollo Telescope Mount (ATM) solar panels faced the Sun to provide as much electricity as possible. Because of the loss of the meteoroid shield, however, this positioning caused workshop temperatures to rise to 126 degrees F. The launch of Skylab 2 was postponed 10 days while NASA engineers developed procedures and trained the crew to make the workshop habitable. At the same time, engineers "rolled" Skylab to lower the temperature of the workshop. Skylab's 2nd manned mission - May 25th to June 22nd Astronauts; Charles Conrad, Jr. Paul J. Weitz Joseph P. Kerwin The crew meats with Skylab on the fifth orbit. After making many repairs, including deployment of parasol sunshade which cooled the inside temperatures to 75 degrees F, by June 4 the workshop was in full operation. In orbit the crew conducted solar Earth resources experiments, medical studies, and five student experiments; 404 orbits and 392 experiment hours were completed; three EVAs that totaled six hours, 20 minuets. Skylab's 3rd manned mission - July 28th to September 25th, 1973 Astronauts; Alan L. Bean Jack R. Lousma Owen K. Garriott Continued maintenance of the space station and extensive scientific and medical experiments. Completed 858 Earth orbits and 1,081 hours of solar and Earth experiments; three EVAs totaled 13 hours, 43 minuets. Skylab's 4th mission - November 16th, 1973 to February 8th 1974 Astronauts; Gerald P. Carr William R.

BPL Rise N Fall Down

BPL has a pioneering legacy in Indian electronic industry. In 1963, BPL came into being in collaboration with the erstwhile British Physical Laboratories, UK, to manufacture hermetically sealed panel meters. It was a small beginning. In a few years BPL ventured into medical electronics and then test & measuring instruments. In 1968 BPL introduced India’s Indigenously built first ECG machine – the Cardiart T108. It instilled confidence that with ingenuity and commitment we can match the best in the world. It showed the way for bigger things to come. In the 1970s, BPL began catering to national power grids with Power-line Carrier Communication systems. In the first two decades of its existence BPL was a brand built on its technological strength in professional electronic products. In the 1980s, BPL forayed into consumer electronics. Soon BPL became a trusted household brand reputed for its wide range of reliable products that included entertainment and leisure products such as colour TVs, music systems and video players, and home appliances such as refrigerators, washing machines and microwave ovens. Meanwhile, extending its expertise into telecom, BPL started making EPBAX and telephone instruments. In the 1990s BPL expanded its footprint to include mobile telephony services with BPL Mobile. The company also started manufacture of alkaline batteries and indigenous manufacture of CRT for TVs. With relentless commitment BPL became recognized as the market benchmark for new age technology and digital concepts, superior product quality, and easily accessible service. This ensured loyal customers and nationwide acclaim in the industry. BPL carved itself a place in over 20 million homes and hearts. Looking at the future BPL will make a sustainable difference in peoples lives, be it with affordable yet reliable LED lighting system for homes at the bottom of the pyramid, with medical equipment for growing need for primary healthcare or by making life enjoyable and safe with lifestyle enhancement products. Fall of bpl Sanyo was surprised BPL was not seeking the kits like every other company, but was asking for transfer of technology to fully manufacture TVs in India, Nambiar said in an email to Mint. That was a tall task considering India had practically no local vendors to supply most of the components needed to make colour TVs, which was something BPL set out to do. But the entry of LG and Samsung meant serious competition. â€Å"The Koreans, with their relentless focus on customizing products for the local market, cost-cutting and global volumes had a huge edge,† said a former BPL group senior executive who did not want to be identified. â€Å"Why, the Koreans have even dethroned the Japanese globally. Today, Samsung which initially copied from Sony, is larger than that firm. †

Analysis Of Julius Caesar s The Gallic War - 1070 Words

Critique Essay In this critique of Julius Caesar’s book, The Gallic War, I will be discussing the purpose and accuracy (or in this case, inaccuracy) over his adventures and military campaign against the Gallic tribes. There is a constant debate between historians: The Myth of Certainty. History is all about interpretation and finding truth out of subjectivity. History can often be lost in time as the firsthand accounts will eventually fade out. Even if firsthand accounts remains intact, it is not completely objective. Every person has their own agenda and is biased in one shape or form, no matter how much they try not to be; Julius Caesar is not an exception. I will start this critique by stating the author’s main purpose for writing his book. Secondly I will attempt to decipher the accuracy and inconsistency of Julius Caesar’s account. Finally, I will express my opinion over his commentaries over the Gallic War. There were many reasons to why Julius Caesar wro te his book over the Gallic War. One of these reasons was to help inspire the people of Rome. Rome had just been sacked by the Gaul, creating tension between the Roman people and the Celtic tribes. The growing resentment towards the Gallic people spread like wildfire as political turmoil rise. Although the Romans were very tenacious and persevering, this did not stop the morale blow that many Romans felt. Another reason for the commentaries was to justify Caesar’s invasion.
