Timeline of events and causes of the Challenger Space shuttle accident
In 28 January 1986, the Space Shuttle Challenger was launched for the Last time and exploded less than 2 minutes after the lift-off resulting in the deaths of all seven crew members on board (Space shuttle challenger: Wikipedia, 2006).
The failure of the solid rocket booster o-rings was attributed to several factors, including faulty design of the solid rocket boosters, insufficient low temperature testing of the O-ring material and lack of communication between different levels of NASA management.

Once functional, the shuttle became exposed to operational demands from a multitude of users as NASA endeavoured to live up to its promises. Coordinating the needs of political, commercial, military, international and scientific communities placed immense pressures on the shuttle management team (nasa: government, 2006). • Political pressure to provide a reliable reusable space vehicle with rapid turn-around time and deployment seriously hindered the ability for effective systems integration and development. • It was not feasible to construct any complete management support systems that could integrate all of the factors associated with such a diverse group in the operational environment.
The push of the Reagan administration to declare the shuttle ‘operational’ before the ‘developmental’ stage was completed created uncertainty and low NASA employee morale
The process of ‘selling’ the concept of a re-usable space transportation system to the American public and its political system started in the late 1960’s, following the successful Apollo mission. The space shuttle was approved as a method for operating in space without a firm definition of what it goals would be (unlike previous NASA programmes). Support for the project, both politically and economically, was not very strong (nasa: government, 2006).
These factors created an environment in NASA preceding the
Then came the disaster that would change not only change space, but also US history. The Challenger exploded mid-flight on their way to their historic mission. What went wrong? What actually happened to cause a veteran space shuttle such as Challenger to dysfunction on its tenth run? A videotape showed black smoke coming from the bottom field joint of the right solid rocket booster (SRB). The black smoke suggested that grease, joint insulation, and rubber O-rings were being burned. The smoke continued to come from the bottom field joint facing the exterior tank in cycles of three puffs of smoke per second. The black smoke was an indication that the bottom field joint was not sealing correctly. Into flight the a flame was seen coming from the right SRB. The flame was coming from the underside of the bottom joint. As the flame increased in size, it had begun to push against the external tank due to the rushing air around the orbiter. Soon later there was a sudden chain of events that destroyed Challenger and the seven crew members on
On the morning of January 28th, 1986, Americans watched in shock and horror as the space shuttle Challenger exploded only 74 seconds after its launch, killing all seven crew members on board including a high school teacher Christa McAuliffe. Thousands, including families of the crew and schoolchildren
On January 28, 1986, the Space Shuttle Challenger “violently exploded” tragically after 73 seconds of flight (Reagan). Ronald Reagan then came out to remind everyone of the importance of mistakes like this and not to let them destroy people's confidence. He stated, “It’s all part of the process of exploration and discovery. It’s all part of taking a chance and expanding man's horizons. The future doesn’t belong to the fainthearted; it belongs to the brave.
Well known president, Ronald Reagan, in his address to the nation, “Explosion of the Space Shuttle Challenger,” expresses grief for the explosion of the Challenger. Reagan’s purpose is to commemorate the seven men and women, who lost their lives and offer hope to those who will continue to explore space. He creates a sad, yet hopeful tone in order to convey to America, we all mourn the loss of the Challenger Seven, but our space program will continue.
As President Eisenhower once stated, “Every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed” (qtd in DeGroot). According to Jerry DeGroot, a lecturer in the Department of Modern History at the University of St. Andrews and author of the widely acclaimed biography “Douglas Haig”, every year, the United States federal government funds the National Aeronautics and Space Administration (NASA) with over $17 billion. When Keith Yost, a professor at the Massachusetts Institute of Technology (MIT), was asked about government funding on NASA, he replied, “NASA is not only spending money, but also the sweat of our laborers, the genius of our scientists, and the hopes of our children.” As a powerhouse in the work industry, NASA is taking away from the remainder of the country. Before venturing off into space, the US needs to realize the importance of tackling the issues that lie before the citizens here on Earth. As Richard Truly, a retired Vice Admiral in the United States Navy, stated in agreement, “...I didn’t go to NASA for the United States to make international commitments that wouldn’t keep, to design space vehicles that will never be built (or will be then fail), or to make promises to the American people that will never be kept.” It would be in the best interest for the citizens of the United States federal government to cut NASA funding.
On January 28, 1986, as millions of Americans watched on live television and in person, the Challenger space shuttle exploded and broke up over the Atlantic Ocean just moments after its launch. This space mission was significant for several reason, among them was that it would be the first time where the space shuttle would carry a civilian into outer space. Also, there was a frenzy of interest for Americans as the U.S. and Russians were locked in a space race for space exploration supremacy. Instead. President Ronald Reagan was left with the unenviable duty of consoling a nation that had just witnessed the most significant disaster in American history.
President Ronald Reagan inherited the space policy of his predecessor, Jimmy Carter and was not satisfied with its current objectives and lack of direction (Logsdon, 1995). He put together a transition team to draft a new chapter for NASA which was left in an “untenable position” by Carter’s lack of direction for the agency. The NASA transition team leader, George Low, remarked that NASA can be “the best in American accomplishment and inspiration for all citizens” (Logsdon, 1995). The team provided input to Reagan that would drive space policy during his eight year tenure.
"Give me a challenge and I'll meet it with joy.” Ronald Reagan described the five astronauts and two payload specialists who died in the Challenger explosion, about six hours after the Space Shuttle Challenger exploded 73 seconds into its launch. Ronald Reagan’s Address to the Nation would be broadcasted on television and radio nationwide. In this speech, Reagan tells us that this is a day to remember and mourn the loss of the brave challenger crew. Reagan argues that we are pioneers on space travel, and while this is a tragic loss, we must continue to expand our knowledge of space and keep exploring the “Final Frontier.”

On 1st of February, 2003, the space shuttle Columbia exploded when it re-entered the Earth’s atmosphere after finished a 16 days mission in space. All seven astronauts were dead because of this incident. The National Aeronautics and Space Administration (NASA) had stopped the space shuttle program for more than two years to investigate this tragedy. In the 16 days period, the astronauts did approximately 80 experiments on different categories, for example, life science and material science [1]. An investigation later has found out that the disaster was caused by a problem on the day that took off on 16th of January.
On January 28, 1986, a day that was supposed to be filled with excitement and exploration, suddenly turned into a day filled with tragedy and sadness. The space shuttle Challenger was supposed to carry a seven member crew into orbit with one unique member along for this particular mission. Christa McAuliffe was supposed to be the first teacher to go into space as a member of the Teacher in Space Project. Due to this occasion, the media coverage and the number of viewers of this mission was extensive, particularly in schools across the nation. The Challenger lifted off shortly after 11:30 A.M., but tragically only seventy three seconds after takeoff it exploded sending debris and the seven crew members back to earth and into the Atlantic
On the morning of Janurary 28th 1986, the world witnessed in shock and horror what was known as the Challenger disaster as the space shuttle exploded only 73 seconds after its launch, killing all seven crew members onboard including one teacher Christa McAuliffe. Approximately 17 percent of Americans watched the live broadcast of this launch, many of them schoolchildren including those from McAuliffe’s school. From this grave moment emerged an exigency that demands immediate action by the president. Later on that same day, President Ronald Reagan delivered his Challenger address to the nation.
Unfortunately, there is always risk when it comes to space flight. This makes it difficult to determine what constitutes an “Acceptable” risk. A space agency has many worries such as their reputation with the public and the world, the success of their missions, and most importantly the lives of their staff and astronauts. Engineers are usually technically gifted but lacking in organization. This spawns a need for non-technical managers to oversee the day to day operations of projects and companies. While the engineers worry about the functionality of the project (in this case, a space shuttle), the managers worry about the cost to the company and the infamous pick 2 triangle of good, cheap, fast. This causes a disconnect between the engineers and the management where pressure from anything whether it be the public or CEO, can cause concerns to be overlooked.
Many critics believe that NASA and space exploration should not be the main focus of the government. However, NASA is not just about flying rockets and putting men into space. There is science and engineering that is being developed to push humanity forward in life. This space program is essential to answering philosophical questions, creating new technology for practical everyday use, the international collaboration with other countries, and the long-term survival of the human
Seventy three seconds into its 10th flight, on January 28, 1986, the Space Shuttle Challenger broke apart over the Atlantic Ocean, killing the seven crew members on board [1]. The Challenger was the second space shuttle constructed by NASA and had completed nine successful missions prior to the disaster. Following the accident, the shuttle program was suspended for 32 months as President Ronald Regan appointed a Commission, chaired by William P. Rogers and known as the Rogers Commission, to investigate the cause of the accident [1].
