NASA officials sidestepped questions on Artemis II risks—there's a reason why
“This ought to make for some good reading,” NASA’s mission management team chair said.

TL;DR
- NASA officials have been reluctant to provide specific risk assessment numbers for the Artemis II mission.
- The mission's novelty and single previous test flight (Artemis I) make it difficult to quantify risks.
- NASA managers are focusing on risk mitigation rather than precise probabilistic figures.
- The Artemis II mission is scheduled for liftoff no earlier than April 1.
- The four-person crew expressed concerns during the Flight Readiness Review regarding the spacecraft's heat shield, reentry trajectory, communication, and life support systems.
- Previous launch delays were caused by issues with hydrogen seals and helium loading in the SLS rocket.
- Mission managers are opting not to conduct another fueling test, having demonstrated seal integrity.
- NASA aims to reduce the probability of failure on Artemis flights to below 1 in 50, but current assessments for Artemis II fall short of this goal.
- The Apollo 1 fire and Space Shuttle disasters are cited as examples of the dangers of "failure of imagination" and the complexities of risk assessment.
- The Artemis II mission's top risks include micrometeoroids and orbital debris (MMOD), and the environmental control and life support system.
- Astronauts acknowledge the inherent risks but express confidence in the mission and the Orion spacecraft.
