About this Item: Presidential Commission, Washington, DC, 1986. Wraps. Condition: Very good. Presumed First Edition, First printing. Quarto. [6], 256, [6] pages. Volume I ONLY. Wraps. Illustrations (some color). Tables. Charts. Appendices. References. Slight wear to cover and spine edges. Sticker residue inside front flyleaf. Volume I contains the report and appendices AD. Volumes II and III (not present) contain the rest of the appendices; Volumes IV and V (also not present) contain hearings of the Presidential Commission. The Rogers Commission Report was created by a Presidential Commission charged with investigating the Space Shuttle Challenger disaster during its 10th mission, STS-51-L. The report, released and submitted to President Ronald Reagan on 9 June 1986, both determined the cause of the disaster that took place 73 seconds after liftoff, and urged NASA to improve and install new safety features on the shuttles and in its organizational handling of future missions. One of the commission's members was physicist Richard Feynman. His style of investigating with his own direct methods rather than following the commission schedule put him at odds with Rogers, who commented, "Feynman is becoming a real pain." During a hearing, Feynman famously demonstrated how the O-rings became less resilient and subject to seal failures at ice-cold temperatures by immersing a sample of the material in a glass of ice water. Feynman's own investigation revealed a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed misunderstandings of elementary concepts. One such concept was the determination of a safety factor. The commission found that the Challenger accident was caused by a failure in the O-rings sealing the aft field joint on the right solid rocket booster, causing pressurized hot gases and eventually flame to "blow by" the O-ring and contact the adjacent external tank, causing structural failure. The failure of the O-rings was attributed to a design flaw, as their performance could be too easily compromised by factors including the low temperature on the day of launch. "An accident rooted in history" More broadly, the report also determined the contributing causes of the accident. Most salient was the failure of both NASA and its contractor, Morton Thiokol, to respond adequately to the design flaw. The Commission found that as early as 1977, NASA managers had not only known about the flawed O-ring, but that it had the potential for catastrophe. This led the Rogers Commission to conclude that the Challenger disaster was "an accident rooted in history". The report also strongly criticized the decision making process that led to the launch of Challenger, saying that it was seriously flawed. There was a meeting the night before the launch to discuss any major pressing issues that might delay the launch further. Several of the Morton Thiokol engineers stated their concerns about the O-rings and urged a delay, but the concerns didn't get communicated beyond the Level III Flight Readiness Review (FRO). It is certain that even though members of higher FRO teams knew about the issues, there were plenty of members who could have stopped the launch but decided not to. This was done in large part because of the management structure at NASA and the lack of major checks and balances, which proved to be fatal in this scenario. Seller Inventory # 43546
