S1·E6 Sort of Like a Fateful Decision

Having made it to Mars, the Nadesico fends off an attack and locates an underground colony of survivors. But rather than being grateful to be rescued, the survivors have no intention of leaving their home, because they believe the Nadesico will be desroyed before it gets back to Earth! Can Yurika prove that the Nadesico is up to the task, or is the colonists' dire prediction all too accurate?
