Task: Answer Verification
Input (English): Question: Does potassium ferrate [ Fe ( VI ) ] mediate self-sterilization of a surrogate Mars soil?
Answer: Based on our data and previously published descriptions of ancient but dormant life forms on Earth, we suggest that if entities resembling bacterial endospores were produced at some point by life forms on Mars, they might still be present and viable, given appropriate germination conditions. Endospores delivered to Mars on spacecraft would possibly survive and potentially compromise life detection experiments.
Output (English): no
