    • Assuming we do detect a planet that has all the characteristics described by Dr. Sasselov (rocky but watery, slightly larger than the earth, in the Goldilocks zone), how do you think we should follow up to definitely prove that it contains life?

Would you ever be convinced by data that was entirely collected from afar? Explain your answer.
