01 / Abstract

Abstract

This paper separates speculative superconductivity inspiration from actionable spacecraft engineering. Pais-style vibrated-wire superconductivity claims are treated as unverified prompts, not as available technology.

The practical path uses known superconducting physics: zero DC resistance below critical temperature, magnetic-field expulsion, high-current density, and compact high-field coils. The nearest useful spacefaring technology is disciplined cryogenic superconducting subsystems.

02 / Subsystems

Engineering Targets

The paper evaluates superconducting subsystems by total mass, heat, failure, and operational burden, not by conductor resistance alone.

\[ \Delta M_{\mathrm{net}} = M_{\mathrm{copper}} -\left(M_{\mathrm{HTS}}+M_{\mathrm{cryo}} +M_{\mathrm{shield}}+M_{\mathrm{quench}}\right) \]

\[ p_B=\frac{B^2}{2\mu_0} \]

Technology-Readiness Ladder

The conservative path moves from material coupon tests to thermal-vacuum modules and then to small-sat demonstrations.

Coupons Measure critical current, AC loss, bend radius, radiation exposure, and joint resistance.
Cables Test thermal cycling, vibration, quench detection, and current redistribution.
Coils Characterize field strength, stored energy, cryocooler load, and magnetic cleanliness.
Flight Demo Operate a low-risk superconducting power or magnetic subsystem in a representative mission.
