... lifetime ended up being more than twice its original design-life (32 years rather than 15). However, the NASA of the 2020s is clearly intent on reinventing itself. Today, it is no longer developing ‘technical specifications’ in-... it is producing ‘performance specifications’ from which private space companies develop competitive designs that NASA selects after a detailed review. This article explores the status of planning and implementation for...
