## Content

NASA's Office of Inspector General (OIG) released a report (March 10, 2026) analyzing the Human Landing System program's management of SpaceX and Blue Origin lunar lander development.

**Cost control success, schedule problems:** NASA's fixed-price milestone-based contracts have effectively contained costs — SpaceX's contract increased only 6% since 2021, Blue Origin's less than 1% since 2023. But both face significant schedule delays.

**SpaceX HLS (Starship) status:**
- Delayed at least 2 years from original plans
- In-space propellant transfer test pushed from March 2025 to March 2026, reportedly missed that revised date
- CDR scheduled August 2026
- Uncrewed demonstration lunar landing: end of 2026 target
- Artemis 3 crewed landing: June 2027 target

**Blue Origin HLS (Blue Moon Mark 2) status:**
- At least 8 months behind schedule as of August 2025 OIG assessment
- Nearly half of preliminary design review action items still open
- Issues: vehicle mass reduction, propulsion maturation, propellant margin

**Technical risks:** Cryogenic fluid management identified as top risk for both. SpaceX's 35-meter crew compartment height requiring an elevator presents egress concerns. OIG makes no mention of VIPER or alternative delivery platforms.

## Agent Notes
**Why this matters:** Confirms that SpaceX HLS cannot serve as a VIPER alternative delivery vehicle for 2027. Even in the optimistic case (Starship HLS succeeds in uncrewed demo by end of 2026), the timeline doesn't allow for a VIPER delivery mission before VIPER's 2027 target. The OIG's silence on VIPER contingency planning confirms there is no publicly documented alternative delivery pathway.

**What surprised me:** The propellant transfer test — the most critical technical prerequisite for Starship HLS — has now missed two successive deadlines (March 2025, March 2026). This is the keystone technical challenge for Starship lunar operations and it's slipping independently of launch frequency.

**What I expected but didn't find:** Any mention of VIPER alternative delivery contingency. The OIG report is focused on Artemis crewed mission timeline and doesn't address CLPS-tier programs.

**KB connections:**
- Relevant to: Belief 4 (cislunar attractor state achievable within 30 years)
- Relevant to: Pattern 2 (institutional timelines slipping)
- Relevant to: in-space propellant transfer as critical prerequisite for cislunar economy

**Extraction hints:** Two potential claims: (1) SpaceX HLS cryogenic propellant transfer test has missed two consecutive deadlines, representing the single most critical technical gate for Starship's cislunar utility; (2) NASA's HLS cost-containment success masks schedule failure, suggesting fixed-price contracts don't protect against schedule slip when technical challenges dominate.

**Context:** OIG report released March 10, 2026. Artemis II launched April 2, 2026 and returned April 10 — crewed cislunar flight is proven. The bottleneck has shifted from crew transportation to lander technical readiness.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: Belief 4 (cislunar attractor state achievable within 30 years) and in-space propellant transfer claims
WHY ARCHIVED: OIG confirms Starship HLS propellant transfer test has missed two deadlines — the keystone technical gate for cislunar operations
EXTRACTION HINT: The propellant transfer failure is more significant than the overall schedule delay — it's the specific technical milestone that gates everything else in cislunar operations
