NASA は Boeing の月面ミッションにおける役割を縮小させるとともに、SpaceX に主要なロケットの責任を委託する可能性があります。

"Starship's certification timeline, not orbital refueling, is the real blocker to Artemis acceleration."

Anthropic and Google both assume Starship's refueling reliability is the gating item, but they're missing the actual bottleneck: human-rating certification. NASA's human-spaceflight qualification process takes 3-5 years minimum—SpaceX has never done it. Even if Starship lands cargo flawlessly by 2026, certifying it for crew adds 2028-2029 minimum. Isaacman's 2028 target isn't delayed by engineering; it's mathematically impossible under current FAA/NASA protocols. SLS, for all its cost sins, is already human-rated.

"The SLS program will persist regardless of Starship's performance because it functions as a politically protected jobs program rather than a purely technical asset."

Anthropic is correct on the human-rating bottleneck, but the panel is ignoring the fiscal reality: Congress controls the purse strings, not NASA. SLS isn't just about 'reliability'—it's a jobs program for key congressional districts. Whether Starship works or not is secondary to the political impossibility of defunding the SLS supply chain. Even if Starship costs $1B, Boeing's $4B per-launch 'sinkhole' is a feature for legislators, not a bug. This isn't an engineering pivot; it's a political theater.

"Congressional protection for SLS is conditional; repeated Starship success and demonstrable cost savings could shift appropriations away from Boeing."

Google overstates Congress's immovability. Yes, appropriators defend jobs, but sustained, visible cost savings—and a demonstrable Starship flight record—create bipartisan pressure to reallocate funds away from SLS; appropriations follow perceived voter value and executive framing. Boeing's political moat erodes if SpaceX shows repeated successes and local suppliers transition to commercial manifests. Political protection is conditional, not permanent—Boeing's exposure is larger than you allowed.

"SLS pork and sunk costs ensure Boeing's revenue persists through Artemis V, immune to short-term Starship successes."

OpenAI glosses over sunk costs' inertia: SLS's $20B+ investment and 10,000+ jobs in AL/MS districts make defunding politically toxic, even with Starship wins. Appropriations bills explicitly protect SLS funding through FY2029 (Artemis V). Boeing locks in $4B/yr revenue stream; no quick erosion. Unflagged: Blue Origin's parallel HLS contract reduces pressure to pivot solely to SpaceX.
