The Space Shuttle Challenger disaster occurred on January 28, 1986, when Space Shuttle Challenger broke apart 73 seconds into its flight, leading to the deaths of its seven crew members.

The disaster resulted in a 32-month hiatus in the shuttle program and the formation of the Rogers Commission, a special commission appointed by U.S. President Ronald Reagan to investigate the accident.

The Rogers Commission found NASA's organizational culture and decision-making processes had been key contributing factors to the accident. NASA managers had known contractor Morton Thiokol's design of the SRBs contained a potentially catastrophic flaw in the O-rings since 1977, but failed to address it properly.

Allan McDonald, director of Morton Thiokol's shuttle solid rocket booster (SRB) project, was at Kennedy Space Center for the launch. He and other engineers worried that cold weather would compromise the O-rings.

In the end, MacDonald was so concerned about the potential for a catastrophic O-ring failure and the resulting loss of life that he refused to sign off on the launch. His boss, also an engineer, was concerned as well… but eventually gave his approval to proceed.

In this course, we’ll review the events surrounding the Challenger Disaster. We’ll also examine the ways in which some engineers adhered to their ethical responsibilities, as outlined in the NSPE Code of Ethics, while others compromised safety because of cost and schedule pressures.

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • What caused the worst accident in the history of the U.S. space program
  • Why there was so much pressure to launch this particular mission on schedule
  • NASA’s basis for selecting Morton Thiokol to build the solid rocket boosters (SRBs) for the space shuttle program
  • Why the issue that doomed the Challenger was never fixed, even though tests and flights from 1977 onward showed evidence of the problem
  • Why management did not heed a Thiokol engineer’s warning of the possibility of "catastrophe of the highest order- loss of human life."
  • Why the decision to launch the Challenger in January, 1986 was flawed
  • How weather directly contributed to the disaster
  • What happened to the five engineers who made their concerns known to both their senior management and NASA
  • The implications of the statement made by Thiokol's general manager to his fellow vice presidents: "It's time to take off your engineering hats and put on your management hats."
  • How the principles of Engineering Ethics apply to this case

Certificate of Completion
