Entry angle (°)

Ballistic coefficient (kg/m²)

A returning spacecraft sheds nearly all its 7.8 km/s orbital speed as heat in the upper atmosphere. Too shallow an angle and it skips back into space; too steep and the deceleration g-load and heating spike to lethal levels. The ballistic coefficient sets how deep it plunges before the thickening air finally slows it.

Governing equation

\overset{v}{˙} = - \frac{ρ v ^{2}}{2 β}, β = 400 kg/ m^{2}, g_{m a x} = 0.0

Reading this result: A moderate entry angle keeps peak deceleration within a survivable range while shedding orbital speed as heat.
