SpaceX Milestone Schedule & Feasibility Sandbox

Flight Parameters ACTIVE

Technological Impossibility Score 88

Physics barrier and unproven engineering frontier score (0 = solved, 100 = unattempted in human history).

Iteration Cadence (Days / Loop) 14 d

Turnaround time from build to static fire / launch attempt (hardware-rich philosophy).

Dedicated Prototypes in Queue 12 hulls

Parallel test articles manufactured in advance to absorb destructive test failures.

Regulatory Buffer Multiplier 1.6x

FAA environmental reviews, safety mishap licenses, and orbital launch window constraints.

THE ITERATION ADVANTAGE

Fast hardware loops cut uncertainty faster than paper designs. Even when a milestone slips by months, the convergence slope prevents cancellation.

Projected Delay

42.5 months

Shift from Elon Time to Real World

Confidence Score

78.4%

P80 Monte Carlo breakthrough threshold

Feasibility Status

Late But Inevitable

Starship Rapid Reusability & Mars Transit

Optimal Iteration Speed

12-day test loops

Target for hardware-rich convergence
