- He gave a 1-in-20 catastrophic failure probability before launch. Orion returned safely, but the heat shield data he cited as unresolved has not been publicly disclosed post-flight.Source: DB event camardas-1-in-20-risk-estimate-half-vindicated

Background
Dr Charles Camarda is a former NASA astronaut and aerospace engineer who flew aboard Space Shuttle Discovery on STS-114 in 2005. Before Artemis II launch he publicly assessed the probability of catastrophic failure at 1 in 20 (5%), describing the trajectory modification as "playing Russian roulette" in statements to Fortune and NBC News. His warning was cited in aerospace media but did not delay the launch. With Artemis II having returned safely, his catastrophic-failure probability did not materialise. However, his estimate went unaddressed again at the 16 April crew press conference, and the heat shield anomaly he referenced has not been publicly resolved.
Camarda's expertise is in structural mechanics and thermal protection systems, directly relevant to the heat shield questions NASA has declined to disclose. He served as an engineer and safety analyst at NASA Langley Research Centre. His pre-launch critique was institutional as well as technical: he argued that NASA safety culture had not adequately internalised the lessons of Columbia, particularly the pressure to meet schedule.
Mission survival resolves the Artemis II outcome. It does not resolve the Bolt melt-through scenario the OIG documented in IG-24-011, the scenario from which Camarda's estimate was partly derived. The formal 30-day KSC heat shield scan, not yet under way at the crew conference, is the first data that could begin to address his technical concerns.
