Which risk increases when a spacecraft shield undergoes rapid micrometeoroid bombardment?

A)Capacitance discharge induces unintended thruster firing
B)Heat shield sublimation accelerates unexpectedly faster rate
C)Electromagnetic pulse disables onboard gyroscopes
D)Metal fatigue lowers temperature damage threshold

💡 Explanation

A micrometeoroid strike charges the shield, and capacitance discharge generates current because accumulated charge tunnels through weakened insulators, therefore, triggering parasitic current, rather than bulk heating, or damage thresholds.
