How it works

Core temperature follows a lumped heat balance — the same relation as the article's ΔT = Q/(m·Cp), written as a rate equation:

C_th · dT/dt = Q_heater − h(P)·(T − T_hull)
h(P) = h0 · (P / 101 kPa)

Lower chamber pressure means fewer gas molecules to carry heat by convection, so it insulates the organism from the −40 °C hull chill; higher pressure conducts heat away faster.

Metabolic uptake follows Michaelis–Menten saturation in the nutrient infusion rate [N], then a Gaussian thermal-performance curve scales it by how close the core temperature is to the organism's optimum:

M(N) = Vmax · N / (Km + N)
f(T)  = exp( −((T − Topt) / σ)² )
Metabolic rate = M(N) · f(T)

Tissue stress accumulates when temperature drifts from Topt, when effective metabolism falls into starvation range, or when pressure leaves the safe band — and relaxes on its own whenever all three sit inside the safe zone at once. Random hull micro-fractures occasionally jolt the ambient temperature, exactly like the containment breach risk described in the source article.

Heater / chiller — direct thermal power Q into the chamber (negative = active cooling).
Nutrient infusion — sets [N] feeding the Michaelis–Menten uptake curve.
Chamber pressure — trades off insulation against the organism's safe barometric band (60–140 kPa).
Auto-Stabilize — a simple proportional controller nudges all three toward the setpoint that minimizes stress.
