Which risk increases when an interstellar spacecraft's velocity approaches relativistic speeds?

💡 Explanation

An increase in speed increases micrometeoroid impact frequency, due to relativistic effects compressing spacetime in the direction of travel. Because of length contraction, the spacecraft experiences a higher flux of particles along its path, therefore micrometeoroid risks escalate, rather than internal malfunctions, because other systems don't interact directly.
