![]() ![]() Statement by Joseph H. Rothenberg Associate Administrator For Space Flight Washington - March 9, 2000 - As the result of ascent anomalies experienced on STS-93, I asked Dr. Henry McDonald (Center Director, Ames Research Center), on September 7, 1999, to lead an independent technical team to review the Space Shuttle systems and maintenance practices. The team, comprised of NASA, contractor, and DOD personnel, looked at NASA practices, Space Shuttle anomalies, and civilian and military aeronautical experience. My goal for this study was to bring to Space Shuttle maintenance and operations processes a perspective from the best practices of the external aviation community, and where applicable/appropriate, apply these practices to the Space Shuttle. This report fully endorsed the continuation of Space Shuttle flights after disposition of the team's immediate recommendations. Additionally, the Space Shuttle Independent Assessment Team (SIAT) was continually impressed with the skill, dedication, commitment and concern for astronaut safety and the entire Space Shuttle workforce. The SIAT documented many positive elements during the course of their interviews with the Space Shuttle NASA/contractor workforce. Particularly noteworthy were the observations dealing with the skill and dedication of the workforce. Independent assessments, like the SIAT, have been used repeatedly throughout the history of the Space Shuttle program. NASA's goal for these independent assessments has been to identify opportunities to improve safety. The SIAT report will provide additional input to the full range of activities already underway associated with Space Shuttle upgrades, including maintainability, processes for shuttle safety and quality control. This report brings to Space Shuttle maintenance and operations processes a perspective from the best practices of the external aviation community. The SIAT focused their activities on eleven technical areas: Avionics, Human Factors, Hydraulics, Hypergols and Auxiliary Power Unit, Problem Reporting and Tracking Process, Propulsion, Risk Assessment and Management, Safety and Mission Assurance, Software, Structures, and Wiring. They documented 81 recommendations in four categories:
It is expected that actions to be taken in response to this report will cover near-term and long-term strategies that will lead to the development and infusion of new technologies and practices.
The report led by former Mars Pathfinder Project Manager Tony Spear was chartered by the Office of the Chief Engineer in mid- 1999 to make recommendations on a set of principles, tools and processes for ensuring NASA's success in adopting the "Faster, Better, Cheaper" approach to project planning, management and execution. The Mars Climate Orbiter Phase I Report, released Nov. 10, 1999, identified the root cause and factors contributing to the Mars Climate Orbiter failure. The charter for this Phase II report, also led by Marshall Space Flight Center Director Art Stephenson, is to derive lessons learned from that failure and from other failed missions - as well as successful ones - and from them create a formula for future mission success. An additional report, from the Mars Independent Assessment Team chaired by Thomas Young, will be available by the end of March. The team was chartered by Associate Administrator for Space Science Dr. Ed Weiler in the wake of the Mars Polar Lander failure to evaluate recent successful and unsuccessful deep space missions. Their assessment and findings will be considered in planning for future Mars exploration missions.
