Final answer:
The Challenger disaster was attributed to neglected responsibilities, including ethical considerations, safety protocols, and communication procedures, with crucial warnings about the O-rings in cold temperatures not being properly conveyed or heeded by NASA decision-makers.
Step-by-step explanation:
In the case of the Challenger space shuttle disaster, several professional responsibilities were neglected. Among these, ethical considerations, safety protocols, and communication procedures were prominent. There was a failure to adhere to ethical responsibilities in the decision-making process, as engineers from Morton Thiokol (the contractor responsible for the solid rocket boosters) initially recommended against the launch due to concerns about the effects of low temperatures on the O-rings. However, under pressure from NASA, they reversed their decision.
Safety protocols were also compromised; the warnings about temperature effects reflected a known design flaw that was not sufficiently addressed. The O-rings that sealed the joints of the SRBs were not designed to handle the unusually cold temperatures on the day of the launch, leading to the shuttle's destruction shortly after liftoff.
Communication procedures were inadequate in that concerns from engineers were not fully communicated or considered by NASA decision-makers. This breakdown in communication led to NASA managers disregarding the potential risk and proceeding with the launch. No evidence points to budgetary constraints directly impacting the decision to launch, although it is always a consideration in space missions.
