← ScienceWhich risk increases when a spacecraft's molecular sieve malfunctions?
A)Increased condensate accumulation and filter blockage✓
B)Reduced spacecraft skin embrittlement resistance
C)Compromised thermal radiation dissipation performance
D)Accelerated solar panel electron degradation
💡 Explanation
Increased condensate occurs because a malfunctioning molecular sieve decreases water vapor adsorption, resulting in condensate accumulation and potential filter blockage; therefore filter blockages increase, rather than embrittlement, radiation, which require different failure modes such as thermal loading.
