Oficina del Inspector General de la NASA (NASA OIG) (15 de noviembre de 2021), NASA’s Management of the Artemis Missions, NASA, p. 21, consultado el 18 de enero de 2023, «To account for all Artemis costs for FYs 2021 through 2025, including Phase 2 projects like the SLS Block 1B, Mobile Launcher 2, and Gateway, we found that $25 billion should be added to the Artemis Plan’s estimated costs, increasing the total costs over this 5-year period to $53 billion. Furthermore, when considering the $40 billion already spent on the Artemis mission from FYs 2012 to 2020, the total projected cost through FY 2025 becomes $93 billion.».

First, a power and propulsion element will launch in 2022. Then, the crew module will launch (without a crew) in 2023. In 2024, during the months leading up to the crewed landing, NASA will launch the last critical components: a transfer vehicle that will ferry landers from the Gateway to a lower lunar orbit, a descent module that will bring the astronauts to the lunar surface, and an ascent module that will bring them back up to the transfer vehicle, which will then return them to the Gateway.»
