NASA’s ambitious plans to return astronauts to the Moon by 2028 are facing significant hurdles, according to a new report from the agency’s Office of Inspector General (OIG). The report, released Tuesday, highlights critical gaps in testing and crew survival analyses for the human landing systems (HLS) being developed by SpaceX and Blue Origin – raising concerns that astronauts could be stranded on the lunar surface in the event of a catastrophic failure. The findings underscore the immense technical challenges of landing humans on the Moon and the critical need for robust safety measures.
The Artemis program, aiming to establish a sustained human presence on the Moon, relies on these new lunar landers to ferry astronauts from lunar orbit to the surface and back. However, the OIG report reveals a troubling lack of a dedicated rescue capability. “Without a rescue capability for the Artemis missions, the crew will be lost should the HLS turn into disabled on the lunar surface or be unable to dock with the awaiting Orion or Gateway in [lunar orbit],” the report states, emphasizing the potentially fatal consequences of a lander malfunction.
The report comes on the heels of a recent overhaul of the Artemis program, which included adding an additional test flight to prepare for a crewed Moon landing and working to standardize the Space Launch System (SLS) rocket for more frequent launches. NASA’s current schedule targets Artemis 4 for a lunar landing in 2028, with a potential follow-up mission, Artemis 5, later that same year. The agency is under increasing pressure to demonstrate progress in space exploration, particularly as China also pursues lunar ambitions.
Delays and Disagreements Complicate Lander Development
NASA initially planned to use a modified version of SpaceX’s Starship as the HLS, aiming for a 2027 landing. However, significant developmental delays prompted the agency to reopen the contract in October, leading to a competition with Blue Origin. Both companies are now racing to deliver a functional crew lander by the revised 2028 deadline. According to the OIG, it’s too early to assess the full technical, financial, and scheduling implications of this accelerated development effort.
The report raises concerns about the safety of both spacecraft. Although acknowledging NASA’s proactive approach to hazard mitigation, the OIG identified gaps in the agency’s risk reduction methodology. Specifically, the report points to missed opportunities to apply “test like you fly” principles – a NASA guideline emphasizing testing systems in conditions closely mirroring actual spaceflight – during uncrewed demonstration missions for both SpaceX and Blue Origin.
A key point of contention lies with SpaceX’s Starship HLS and the requirement for manual controls. The OIG report states that NASA and SpaceX disagree on whether the lander currently meets the necessary standards for crew control in emergency situations. Manual controls are considered a critical safety feature for human-rated spacecraft, allowing astronauts to override automated systems if needed. The status of manual controls for Blue Origin’s Blue Moon lander remains unclear, according to the report.
Crew Survival Analyses Lack Depth
Beyond the landers themselves, the OIG also criticized NASA’s approach to analyzing crew survival in the event of a catastrophic event. These “crew survival analyses” are limited by technical constraints and available resources, and are typically conducted late in the lander design process. This timing means they primarily identify risks rather than informing design choices to reduce those risks. The analyses do not adequately address extended crew survival beyond the immediate aftermath of a disaster.
The report highlights a stark parallel to the Apollo missions, noting that, as in the 1960s and 70s, NASA currently lacks the capability to rescue astronauts who might become stranded in space or on the lunar surface. Spaceflight Now reported on the OIG’s findings, emphasizing the lack of a rescue plan.
Recommendations and Next Steps
The OIG report outlines several recommendations for NASA to improve HLS program management and enhance crew safety. These include establishing clear rules for tracking government funding provided to contractors, updating contract language to reflect those rules, reviewing lessons learned from the Commercial Crew Program regarding manual spacecraft controls, and improving crew survival analyses to incorporate strategies for long-term survival. NASA has reportedly agreed to implement most of these recommendations.
As NASA addresses these concerns, the pressure to land astronauts on the Moon before China remains intense. Overcoming the technical challenges and ensuring crew safety will be paramount as the agency moves forward with the Artemis program. The agency is currently preparing the Space Launch System rocket and Orion crew capsule for the Artemis II mission, a planned flight around the Moon scheduled for around April 1, 2026, though it has faced delays due to propellant leaks and upper stage issues. NASA’s Office of Inspector General detailed these challenges in its recent report.
The future of lunar exploration hinges on addressing these safety concerns and ensuring that the next generation of Moon landings are not only ambitious but also secure. What comes next will be closely watched by both the space community and the public as NASA navigates the complexities of returning humans to the lunar surface.
