NASA implements multiple testing levels, independent validation, and safety communities to ensure software safety for the Space Shuttle and Orion MPCV. Darrel Raines discussed the importance of learning from failures and improving processes. Software development has evolved significantly since the Space Shuttle era due to available tools. Programs require 4 to 7 testing levels, with diverse teams facilitating broader perspectives. The NASA Software Quality Assurance team monitors software development, identifying defects and ensuring quality. A continuous evaluation of safety practices emphasizes the commitment to improving overall software safety.
NASA employs multiple testing levels, independent validation, standards, and safety communities to ensure software safety during the Space Shuttle and Orion MPCV programs.
Raines emphasized that between 4 and 7 testing levels are required before software is considered safe for flight, involving different teams for diverse perspectives.
