Loss of Signal: Aeromedical Lessons Learned from the STS-107 Columbia Space Shuttle Mishap

Loss of Signal: Aeromedical Lessons Learned from the STS-107 Columbia Space Shuttle Mishap published on

Authored by National Aeronautics and Space Administration

On the morning of February 1, 2003, the Space Shuttle Columbia underwent a high-altitude, high-velocity breakup during the entry-to-landing phase of flight. The external investigation by the Columbia Accident Investigation Board (CAIB) provided the overall causes of the accident in a report that included an analysis by the Crew Survivability Working Group to determine the cause of the crew members’ deaths and the lessons learned. The next year the Space Shuttle Program commissioned the Spacecraft Crew Survival Integrated Investigation Team to perform a comprehensive analysis of the accident, focusing on factors and events affecting crew safety and developing recommendations for improving crew survival for future human space flight. This report was published in December 2008.
Loss of Signal presents the aeromedical lessons learned from the Columbia accident that will enhance crew safety and survival on human space flight missions. These lessons were presented to limited audiences at three separate Aerospace Medical Association (AsMA) conferences: in 2004 in Anchorage, Alaska, on the causes of the accident; in 2005 in Kansas City, Missouri, on the response, recovery, and identification aspects of the investigation; and in 2011, again in Anchorage, Alaska, on future implications for human space flight. As we are embarking on the development of new spacefaring vehicles through both government and commercial efforts, the NASA Johnson Space Center Space Life Sciences Directorate (SLSD)1 proceeded to make this information available to a wider audience engaged in the design and development of future space vehicles.
