Before going any further with this paper, I would like to take a moment to thank the crew of the space shuttle challenger for their bravery, courage, determinations and and sacrifice for this great nation. Francis R. Scobee (2), Commander, Michael J. Smith (1), Pilot Judith A. Resnik (2), Mission Specialist 1, Ellison S. Onizuka (2), Mission Specialist 2, Ronald E. McNair (2), Mission Specialist 3, Gregory B. Jarvis (1), Payload Specialist 1, Sharon Christa McAuliffe (1), Payload Specialist 2 (science.ksc), were parents, friends, children, husbands and wives, heroes, smart human being that were killed on this tragic day. May God be with your soul and may your memories and courage and passion shall not be forgotten but instead drive future generation determination and passion. The crash of the space shuttle

The integrity of the structure and of the seals of all joints should be not less than that of the case walls throughout the design envelope (rec 198, nasa.gov).
It took NASA a couple years to resume its flight to orbit. The catastrophe of the space shuttle challenger shook them up and have rethink their procedures and methods of operation. NASA, improve or I should say worked on developing its shuttle management structure, its shuttle safety panel, critical review and hazard policy, communication, safety organization and many more.
The crash of the space shuttle challenger could have been avoided and yet, the life of the crew members could have been spare if all the safety precaution were taken into considerations. We learn and improve ourselves from our mistakes, but we still have the choices to prevent those mistakes from happening by doing things right and the way there are supposed to be done. May they rest in
"One small step for man, one giant leap for mankind," said by Neil Armstrong as he took his first steps on the moon during the NASA Apollo 11 expedition to the moon. No man has ever been to the moon before and NASA, The National Aeronautics and Space Administration, was the first to get someone to land on the moon. NASA has had many great accomplishments in exploring the "new frontier" that have affected the United States ever since it was first created in July 1958. The idea for NASA first started when the Soviet Union launched the first satellite on October 4, 1957. United States started up its own space travel program and started to work on its own projects that would be better in than the Soviet Union's. This all started the great space race. It was a big race between the Soviet Union and the United States to see who could learn and discover the most. The United States and Soviet Union started building and sending satellites and space ships. Then they tried to see who could make a suit and ship that would be able to allow a living thing to go up in space. They tested out all of the equipment with monkeys and dogs, seeing what would work. Many animals did die in the process but by the results of their testing they were able to build suits and ships that allow human beings to go up in space. Even though they were able to create these machines, that doesn't mean that they didn't have their difficulties and dangers. Two space shuttles were crashed or blown up. There were many key factors that they had learned to fix that resulted in the crashing of those ships. They have made many discoveries and accomplishments like having the first astronauts walk on the moon.
The first would include a tour of the Challenger itself. The second is about the future of space travel. During the Challenger Mission, Christa McAuliffe and six others used the Challenger. This accommodation had up to two thousand displays and instruments, and carried about five computers. It was cold that morning on the lift off in Cape Canaveral, Florida.
In a person’s lifetime, many things can happen including death. In 1986 seven individuals, Michael Smith, Dick Scobee, Judith Resnic, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe, lost their lives doing what they loved most. The tragedy of the shuttle challenger brought much pain to the nation that day. Along with the pain comes grieving. The nation grieved the loss of these seven wonderful individuals and hoped to find peace and comfort for the days to come. As Ronald Reagan prepared to give the state of the union address, things changed for worse, he unexpectedly had to give a speech on a horrific event. Reagan was devastated at the loss of the seven men and women that were on that space shuttle challenger.
Contextual analysis is made up of three basic components; intended audience, setting and most importantly purpose. Authors often times consider and work each contextual piece into the construction of their given argument. An argument is not powerful if audience preference is not a main concern, if the setting isn’t taken into consideration, or if the purpose is not relevant to the current situation. On January 28th, 1986 the shuttle challenger exploded 73 seconds into its take off. President Ronald Reagan wrote a critical speech to address the tragedy that had struck our nation that day. It is highly evident in his address that kept audience, setting, and purpose in mind. He comforts a worried public using calm tone and simple yet effective diction to convince the American nation that it’s necessary to go on and continue the space program and ultimately the scientific revolution.
Space travel began in the 1960s with sending humans on single missions into space. Rockets launched into the air and just the tip would land in the ocean after parachuting back to Earth ("Space Shuttle Program," par. 4). The focus of space exploration changed during the 1980s; shifting from the desire for human space flight to the desire to create a reusable spacecraft. Originally called Space Transportation System (STS), NASA created the Space Shuttle Program (SSP) (Heiney, par. 1-2). It wanted a shuttle that was more economical because it could be launched, landed and relaunched and could gather better information. The 1980s began a new era in space exploration and had one the biggest tragedies in the history of space travel.
NASA has faced many tragedies during their time; but one can question if two of the tragedies were preventable by changing some critical decisions made by the organization. The investigation board looking at the decisions made for the space shuttle tragedies of the Columbia and Challenger noted that the “loss resulted as much from organizational as from technical failures” (Bolman & Deal, 2008, p. 191). The two space shuttle tragedies were about twenty years apart, they both had technical failures but politics also played a factor in to these two tragedies.
Lack of authority and direction at NASA: The agency did not have a permanent administrator for almost four months and there was a high turnover rate among the high level management employees.
The Challenger disaster of 1986 was a shock felt around the country. During liftoff, the shuttle exploded, creating a fireball in the sky. The seven astronauts on board were killed and the shuttle was obliterated. Immediately after the catastrophe, blame was spread to various people who were in charge of creating the shuttle and the parts of the shuttle itself. The Presidential Commission was decisive in blaming the disaster on a faulty O-ring, used to connect the pieces of the craft. On the other hand, Harry Collins and Trevor Pinch, in The Golem at Large, believe that blame cannot be isolated to any person or reason of failure. The authors prove that there are too many factors to decide concretely as to why the Challenger exploded. Collins and Pinch do believe that it was the organizational culture of NASA and Morton Thiokol that allowed the disaster. While NASA and Thiokol were deciding whether to launch, there was not a concrete reason to postpone the mission.
It’s very hard to say what steps, if any, could have been taken to prevent the Space Shuttle Columbia disaster from occurring. When mankind continues to “push the envelope” in the interest of bettering humanity, there will always be risks. In the manned spaceflight business, we have always had to live with trade-offs. All programs do not carry equal risk nor do they offer the same benefits. The acceptable risk for a given program or operation should be worth the potential benefits to be gained. The goal should be a management system that puts safety first, but not safety at any price. As of Sept 7th, 2003, NASA has ordered extensive factory inspections of wing panels between flights that could add as much as three months to the time it takes to prepare a space shuttle orbiter for launch. NASA does all it can to safely bring its astronauts back to earth, but as stated earlier, risks are expected.
When writing “In Event of Moon Disaster” William Safire acted as a comforting yet encouraging mother for a grieving nation. While acknowledging the need for the public to mourn and remember the deceased astronauts the writer also tries to boost the morale of the American people exclaiming that the astronaut's sacrifice will not be forgotten.
R. M. Boisjoly had over a quarter-century’s experience in the aerospace industry in 1985 when he became involved in an improvement effort on the O-ring which connect segments of Morton Thiokol’s Solid Rocket Booster. This was used to bring the Space Shuttle into orbit (OEC, 2006). Morton Thiokol is an aerospace company that manufactures the solid propellant rocket motors used to launch the Challenger (Skubik). Boisjoly authored a memo to R.L. Lund, Vice President of Engineering and four others, in regards to his concerns about the flawed O-ring erosion problem. His warnings were ignored leading to the deaths of six astronauts and one social studies teacher.
On a cold winter’s morning on the 28th day of January in the year 1986, America was profoundly shaken and sent to its knees as the space shuttle Challenger gruesomely exploded just seconds after launching. The seven members of its crew, including one civilian teacher, were all lost. This was a game changer, we had never lost a single astronaut in flight. The United States by this time had unfortunately grown accustomed to successful space missions, and this reality check was all too sudden, too brutal for a complacent and oblivious nation (“Space”). The outbreak of sympathy that poured from its citizens had not been seen since President John F. Kennedy’s assassination. The disturbing scenes were shown repeatedly on news networks which undeniably made it troublesome to keep it from haunting the nation’s cognizance (“Space”). The current president had more than situation to address, he had the problematic undertaking of gracefully picking America back up by its boot straps.
It was on January 28, 1986 at 11:38 A.M. that the shuttle Challenger, NASA flight 51-L, the twenty-fifth shuttle flight, took off. It was the "Teacher in Space" mission. At lift-off, the temperature at ground level was 36° Fahrenheit, which was 15° Fahrenheit cooler than any previous launch by NASA. It was the Challenger's tenth flight. Take-off had been delayed several times. Finally the shuttle had taken off. The shuttle had climbed high in the sky thirty-five seconds after take-off, and it was getting hit by strong winds. The on board computers were making continuous adjustments so the shuttle would stay on course. About eight miles in the air, about seventy-two seconds after take-off, people watched in fear and horror as the shuttle was engulfed by a huge fire ball. All the crew members were killed instantly.
NASA has built its newest space shuttle which is made to set records and take humans further than they have ever gone before to explore unmapped territory, asteroids, and the Red Planet, Mars. There was a test flight scheduled for this amazing machine to fly on Thursday December 4, 2014 but the launch time continued being delayed for multiple reasons. The new apparent launch date is Friday December 5, 2014 at 7:05 AM ET.
By being in a very technologically advanced era, scientists can invent revolutionary devices never thought of. NASA is doing that right now and has been doing that since it began. They are not only climbing the stairs in space exploration but in the medical industry, too. Nevertheless, they are forever changing millions of lives by using all they have discovered. Most of all, they are teaching people a life lesson, to always use the things you have for the greater good. NASA has achieved profound success ever since their start in 1958 and they will continue to make discovery and innovation their first and foremost goal for years to come.
