Prediction text
By late 2026, SpaceX will launch a flotilla of approximately 5 uncrewed Starships to the Martian surface — success relies entirely on autonomous orbital refilling + AI-driven landing telemetry, proving precursor infrastructure for human colonization can be established without human physical labor onsite. | 2026 Mars window launch attempt
Key catalyst: 2026 Mars window launch attempt
Watch events: 2026 Mars launch window; Starship V3 propellant transfer demo
Resolution evidence
Mars launch window opens Nov 2026; Starship V3 orbital refueling unproven; 5 simultaneous Starships implausible at current cadence. Per SPC_008 base rate, Mars timelines miss 100%.
Predictor: Gwynne Shotwell
Evidence about this node from Gwynne Shotwell is multiplied by κ in /api/intake. Lower κ = less weight; floors at 0.10 (effectively silenced) and caps at 1.00 (full weight).
Reference class: mars_uncrewed_landing_window
Successful uncrewed payload delivery to Mars surface within named transfer window
Tetlock-style outside view: at TRF=1 (just predicted), outside view dominates (w_in=0.3). At TRF=0 (deadline), inside view dominates (w_in=1.0). The blend regularizes overconfident inside views toward the historical base rate.
