Timeline of Events and Causes of the Challenger Space Shuttle Accident

January 28, 1986, marks the day of the Space Shuttle Challenger Explosion. A day that will go down in history as a horrible tragedy for both NASA and America. Seven lives were lost that day, including the life of a high school teacher from New Hampshire. Former President Ronald Reagan was tasked with explaining this tragic event to the US people. Because of this, Reagan postponed the State of the Union Address and spoke about the Challenger Explosion instead. In his address to the nation about the explosion of the space shuttle, Challenger, President Ronald Reagan effectively commemorates the loss of the Challenger crew while also celebrating the crew’s achievements and encouraging further space travel by establishing pathos through his show of empathy, employing strong positive connotation, and alluding to the great explorer, Sir Francis Drake.

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].

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

Reagan then reassured that the space program would continue to operate and “what happened today does nothing to diminish it”. This message sought to protect the ongoing space programs and was dedicated to the last sub-audience of his speech: the NASA people. He acknowledged their hard work and expressed sympathy for their loss of friends and coworkers.

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.

"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.”

After nearly a five day delay filled with wind, rain, and freezing temperatures, Challenger was finally ready to go on mission 51-L. It would be the twenty-fifth mission for the world's first fleet of reusable manned spaceships. A spike in public interest in the flight had been caused by the

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.

　　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.

The article includes background information on the event as well as many quotes from people who followed the Challenger mission and remember the tragedy. Many of the quotes express the viewer’s shock at the disaster while others convey a sense of loss. The article also touches on the complacency of NASA leading up to the disaster and refers to a quote which states that “one of the biggest outcomes from the tragedy was the recommendation that NASA needed a stronger safety organization.”

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.

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.
