Source Review: Payload Space "SpaceX and Blue Origin Cargo Lunar Landers"

Summary

Claim 1: Starship HLS Cargo 12-15 t payload (vs 100 t crewed-HLS)

Quote: "12 to 15 metric tons of payload" Verdict: Consistent Why: My calc's 10 t reference payload is closer to the cargo variant than the 100 t crewed-HLS headline. The 100 t figure is the mature Block 2 capability, not the operational near-term cargo configuration. q2.c12 mentions this distinction.

Claim 2: Blue Moon Mark 2 cargo 12-15 t payload

Quote: "12 to 15 metric tons of payload" Verdict: Consistent Why: Confirms the operational payload class. Blue Moon and Starship cargo variants converge on this number, suggesting it's the operational constraint rather than the architectural ceiling.

Claim 3: Blue Moon Mark 1 3 t payload, 2025 targeting

Quote: "three metric tons to the lunar surface" Verdict: Novel supporting Why: Provides a near-term early-era payload anchor (vs the optimistic 12-15 t / 100 t numbers). At 3 t payload and ~$400M per mission, the effective lunar surface delivery cost is ~$130,000/kg in the very-early era — much higher than my early-era figures. The early-era $/kg may be understated in my calc; this is a useful flag for q8 synthesis.

Claim 4: Timeline (Artemis VII 2032 for Starship cargo)

Quote: "Starship lunar cargo delivery scheduled for Artemis VII in 2032" Verdict: Consistent Why: Indicates that the operational cargo era starts mid-to-late in the 2026-2040 band, matching my "mid" and "late" era assumptions. Calendar dates suggest the early-era of my calc is HLS demonstration / single-mission deliveries, not commercial cargo.

Payload Space — cargo lander specs

Trade-press confirmation of cargo lunar lander payload capacities for the chemical-rocket scenarios.

payload-capacities-cargo-variants

• SpaceX Starship HLS Cargo: 12–15 metric tons of payload (NASA statement, April 2024). Note: this is for the cargo variant contract, distinct from the crewed HLS variant's 100 t maximum surface payload.
• Blue Origin Blue Moon Mark 2 Cargo: 12–15 metric tons of payload
• Blue Origin Blue Moon Mark 1: 3 metric tons to lunar surface (smaller variant, targeting 2025 launch on New Glenn)

timeline

• Starship lunar cargo delivery scheduled for Artemis VII in 2032
• Blue Moon Mark 1 prioritized for near-term operational deployment

relevance-to-q2

The cargo-variant payload of 12–15 t (rather than the crewed-HLS 100 t headline) is more realistic for the operational near-term lunar surface delivery scenario. Recalculating with this anchor:

If Starship HLS Cargo delivers 12 t to lunar surface per mission, and per-mission cost is $400–600M (per newspaceeconomy.ca trade press), then the Earth-imports-only lunar surface delivery cost is $33,000–50,000/kg in early Starship era. This is the operational reality, distinct from the Block-2-mature 100 t headline number.

For lunar surface to LEO (reverse direction), this cost roughly doubles or worse — every kg coming back from the Moon requires the lander to carry its own ascent propellant, which was itself launched from Earth at terrestrial cost.

limitations

• 12–15 t cargo variant is the current contracted value; mature Block 2 Starship cargo could exceed this
• Timeline (2032 for Artemis VII Starship cargo) suggests this scenario doesn't begin operationally until late in the q2 era band
• No direct cost figure; cost extrapolated from companion newspaceeconomy.ca source
