Presets

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.

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