Background
The OIG's May 2024 report documented three Orion heat shield failure modes, including an explicit warning that bolt melt could cause vehicle breakup and crew loss. The same audit confirmed a $4 billion per-flight cost for SLS and a $93 billion total programme cost since 2012. related event
The Office of Inspector General is an independent statutory office within NASA, established under the Inspector General Act. It conducts audits and investigations of NASA programmes, contracts, and operations, reporting findings to both the NASA Administrator and Congress. Its reports are public documents.
The OIG's cost and safety findings provide the most authoritative public accountability data on Artemis. Its documented warning about crew loss from bolt melt is the starkest safety language in any official assessment, and its per-flight cost figure has become the reference number in all congressional and media scrutiny of the programme's value.
