Why NASA does what it does is only known by them. They have demonstrated to me they do what they do without requard to the citizens who sent them there. An explanation to the, truth of the anomaly is not something the feel a need to do. I guess they would just leave us to guess, ponder, and if they did a real good job have you follow along and not ask questions.

Even the Phoenix Lander on it way even as we speak is looking only for past life. Now why would the word it that way?
