The Stellar Death Clock: A Computational Application to Earth-Moon Migration using the Full Astroengineering Methodology

Mitigating solar luminosity inflation demands operational astroengineering frameworks capable of modulating the Earth-Moon orbit safely. This fifth installment of the Stellar Death Clock series presents the first full numerical execution of the calibrated methodology from Paper IV. Balancing the non-gravitational tensor bias-variance tradeoff via a 5-year hyper-parameter window, we optimize a controlled retrograde encounter between the asteroid 137 Meliboea and the Earth-Moon system using a RAM-cached Nelder-Mead algorithm within REBOUND. Initialized during an isolated window on August 31, 2027—synchronized with the superior solar conjunction of Venus and Mars—the optimization respects a rigid non-demolition barrier, guiding the asset into a night-side corridor at a periapsis of 16. 97 R_. An 892-day propagation reveals a close-approach displacement of r₄₀ₑₓ₇ = 21, 397. 62 m translating into a permanent secular heliocentric semi-major axis expansion of a_ = +1, 605. 12 m. Telemetry provides empirical proof of the binary adiabatic coupling theorem: the Moon co-migrates symmetrically (1. 0000) with a residual delta of 9 meters. Finally, a passive Jovian wake-trailing gravity assist curtails hyperbolic excess velocity, re-injecting the asteroid into a stable, closed-loop cycler topology. This automated re-centering eliminates active propulsion needs while keeping all inner planet deviations below 0. 0086 km, validating this architecture as a robust computational laboratory for long-term biospheric preservation.
