ASAP Urges NASA to Reevaluate Artemis Mission Objectives Due to High Risk
In a significant development concerning NASA’s ambitious Artemis program, the Aerospace Safety Advisory Panel (ASAP) is calling for a reassessment of the upcoming mission plans. The panel’s concerns center on the sheer number of first-time objectives planned for each mission, especially Artemis 3, which aims to be the first crewed lunar landing of the series. This editorial will explore the issues highlighted and their potential impact on NASA’s lunar exploration efforts.
ASAP Raises Concerns Over Packed Objectives
ASAP members argued that packing too many objectives into single missions increases the overall risk. Bill Bray, a panel member, stated, “Each first milestone carries its own individual risk, and as these risks are compounded and aggregated, it only increases the overall risk posture for any individual flight mission.” The panel is urging the agency to reassess its approach, focusing on a more balanced risk exposure across all flight tests.
Changing Heat Shield Design Heightens Concerns
The situation has worsened with recent changes to the Orion spacecraft’s heat shield. NASA plans to reformulate the Avcoat material used in the heat shield for Artemis 3 and future missions, addressing heat shield erosion observed during the Artemis 1 reentry. These modifications, alongside the substantial new elements such as the Gateway, Blue Moon crewed lunar lander, and a lunar rover, amplify the risks associated with Artemis missions.
ASAP Pressures NASA for a Systematic Approach
The panel recommended that NASA adopt a methodical approach similar to the Apollo program, specifying clear test objectives for each launch to better manage the risks involved. They also suggested aiming for a more consistent cadence in mission launches.
Bray elaborated, “We discussed these issues with NASA’s deputy associate administrator of their Moon to Mars Program Office, Amit Kshatriya, at recent meetings. The panel advised NASA to treat each launch as a test objective, ensuring a regular flight schedule with balanced risk exposure.”
Gateway and HLS: Evolving Plans
The recent SpaceCom conference highlighted evolving plans for NASA’s Gateway and Human Landing System (HLS). For the Gateway, a logistics module’s architecture has been retooled, partly due to unspecified constraints stemming from evolving logistics needs. NASA and SpaceX are nearing the end of contract modifications and plan to unveil new designs during a system requirements review later this year.
Meanwhile, progress on HLS programs has been steady. SpaceX’s Starship HLS, including recent test flights, has seen successful demonstrations of its airlock and elevator, incorporating prototypes of Axiom’s lunar spacesuits. Notably, the company aims to conduct an in-space propellant transfer this year, crucial for transporting Starship to the moon. Conversely, Blue Origin has shown progress, from its New Glenn rocket’s inaugural flight to testing Blue Moon’s landing legs.
Blue Origins vs. SpaceX: Different Approaches
The two companies embody different strategies towards lunar exploration. SpaceX’s rapid testing schedule contrasts with Blue Origin’s more detailed approach, focusing on comprehensive design and development before hardware construction and rigorous testing.
Implications for Future Lunar Explorations
The safety advisory panel’s recommendations and evolving plans for Gateway and HLS could reshape NASA’s Artemis program. By focusing on a more balanced approach to mission objectives and safety, the agency can mitigate the high risks associated with pushing too many first-time feats into consecutive missions.

Looking Forward
As NASA proceeds with its lunar exploration agenda, continuous reassessment and adaptation of mission plans will be crucial. The recommendations from ASAP and the evolving plans for Gateway and HLS represent significant steps towards ensuring a safer and more sustainable approach to lunar missions.
