← ScienceWhich risk increases for spacecraft navigation during strong Gravitational Lensing?
A)Inaccurate astrometry of celestial objects✓
B)Reduced signal strength from distant beacons
C)Degradation of optical sensor components
D)Unpredictable radiation exposure levels increase
💡 Explanation
Astrometric measurements become skewed because light is deflected by spacetime curvature around a massive object; the Gravitational Lensing mechanism bends light. Therefore, positioning calculations become inaccurate, rather than signal weakens or hardware degrades, which involve different physical phenomena.
