Joseph Erhabor Professor Fletcher English 1101 19 November 2014 Apollo 13 Successful and Failure Apollo 13 is one of the most memorable missions in NASA. Apollo 13 how about crew members on the mission. The crew was ready to launch until they had a problem with the ship. They had to hold back the mission for a couple of seconds. The Apollo 13 mission had technical problems with the spaceship. This missions took place in April, 11 1970 (apollo 13).The crew was excited to launch. The crew member…

When Lovell first applied to NASA, he was turned down due to a temporary liver condition. Fortunately for him, NASA selected him in his second application as an astronaut in September 1962. He immediately began training in NASA. He had test flight experience before he became an astronaut, meaning he was used to dealing with in-flight problems. This experience would come in handy on Apollo 13. Apollo 13 was the seventh mission in the American Apollo program and the third targeted to land on the…

Neon is one of the world’s rare and most expensive elements. I chose Neon because of it's uniqueness. In 1898, William Ramsay and Morris Travers at University College London isolated krypton gas by evaporating liquid argon. They had been expecting to find a lighter gas which would fit a niche above argon in the periodic table of the elements. They then repeated their experiment, that time allowing solid argon to evaporate at a slow pace under reduced pressure and collected the gas which came off…

In the 1960s, the United States’ NASA carried out the Apollo program, the third of its manned human spaceflight programs. The goal of the program was to achieve manned exploration of the Moon and retake the lead in the Space Race against the Soviets, who had beaten the US to the first satellite and human in space, and convince the American public of the superiority of the US’ technological capability. After three unmanned flights, mission AS-204 (named Apollo 1 by the crew, and officially…

I choose Neon because of the many things that it can be used for such as cryogenics, lasers and neon signs. Also because neon is so rare compared to other elements Neon was discovered or isolated in 1898 by two chemist named Ramsay and Travers along with krypton and xenon Neon got its name from the Greek word neos which means new Neon is important for lighting,signs,lasers and refrigeration Neon is the fifth most abundant element in the universe but is very rare on Earth(about 0.0018%) of…

two years ago I was sitting at home with the T.V. on, watching my daily news when suddenly the T.V. cut to an emergency broadcast. The ground shook and I knew the worst thing imaginable was about to unfold. The next words out of this reporter’s mouth would decide if I run out the door to the vault or finish my coffee. For the past three years we’ve been at war with almost every country. And today might be the day one of those countries decides to drop nukes and wipe us out the next words would…

“5, 4, 3, 2, 1, Liftoff!” The message came over the intercom, it was time. I engaged the thrusters and aimed for the NARSS(North American Recreational Space Station). This will be my home for 15 years. You are probably wondering how I got here. Ever since I was five years old, I wanted to travel to space. Due to my good grades in math and science, I was able to enter into a competition to be the first to go to a space station resort and school orbiting earth. The station was constructed in 2050…

extreme intensity (5, 5000 ° F). When liquid hydrogen is combined with liquid oxygen, liquid hydrogen has the highest efficiency in relation to how much fuel is used, compared to any other rocket fuels. Since liquid oxygen and liquid hydrogen are both cryogenic, meaning they both can be turned into a liquid, making more storage space for each…

CHAPTER 1 INTRODUCTION 1.1 Background To overcome the problems interconnected with manual involvement in production operations, it is essential to step towards automation. One such sector where manufacturer is focusing is on programmable robots. Robot is an electromechanical device which is used to do the specified work prescribed by the human beings. First robot was invented by George devol in 1954. Robots are controlled with the help of computers; the desired work is programmed with the…

1. Introduction 1.1 Lubrication Friction is caused during machining operation at tool and chip interface. This produces the heat which affects the machining performance in terms of surface finish, dimensional accuracy, tool life and machining cost. To reduce the heat different techniques have been utilized. Earlier, during industrial revolution water was utilized as a coolant but it caused corrosion [1]. With the development of technology different cooling and lubrication techniques have come…
