← ScienceWhich risk increases when a satellite utilizes reaction wheels at maximum angular momentum capacity?
A)Solar panel misalignment degrades power
B)Thermal runaway destroys communication transceivers
C)Bearing lock halts wheel rotation✓
D)Fuel cell capacity limits thruster firings
💡 Explanation
Bearing lock is more likely; because accumulating momentum bleeds off via friction into bearings, excess wheel speed therefore exceeds thermal limits, rather than damaging solar panels directly because angular momentum transfers.
