← ScienceWhich outcome occurs when a spacecraft's onboard systems trigger unexpectedly high transient currents?
A)Component single-event upset occurs✓
B)Fuel cell electrolyte starvation begins
C)Antenna gain becomes frequency-invariant
D)Thermoelectric cooling efficiency improves
💡 Explanation
Single-event upset occurs due to Electromagnetic Pulse (EMP). The transient current induces strong electromagnetic fields because of the skin effect, coupling into sensitive electronics and causing bit flips; therefore, upset results, rather than fuel cell issues or antenna/cooling effects.
