This paper examines key barriers that can possibly inhibit safe and reliable mission execution and, in the worst case, result in loss of human life due to many unknown contributory factors that can lead to Black Swan events. Some of the representative contributory factors include decision errors, overconfidence and a host of common causes including cultural and human factors. Decisions are always easy to criticize in hindsight when more information is available after a major accident. Depending on the type and complexity of the project and/or mission, the catastrophic risks of drifting into failure can be alleviated by implementing uniquely and strategically tailored Integrated-System-of-Systems, dynamic, risk-informed decision management processes. This paper presents some of the lessons learned from James Webb Space Telescope (JWST), NASA's Human Space Flight program, and industry that provide motivation to organizations working on mega-complex missions to prudently accomplish targeted mission success. These lessons are important for future human Lunar, Mars and Beyond missions planned to be pursued by NASA through a public-private partnership using nimble but effective safety-conscious, proven sound engineering practices including implementation of integrated risk mitigation practices. Background: NASA flagship missions explore the unknown in air and space, innovate for the benefit of humanity and inspire the world through discovery. Complex flagship missions include major programs such as Artemis - Mission to Moon, Mars and Beyond; International Space Station; recent-past Space Shuttle Program and advanced robotic space exploration missions such as James Webb Space Telescope (JWST), and Mars Sample Return. Mission failures have serious consequences on safety of astronauts, future scientific exploration missions, national pride, cost, and reputation.
