I heard that it is not completely proven that there is no life on mars
Is that true?
Of course that's true.
Why was everyone blaming the government? They did all they could to get to try to get it unstuck, but that's pretty much impossible, so they're just using it as a stationary platform thing.
And it wasn't a sandstorm. It broke through a layer of hardened material and got stuck in the soft crap below.
Still a sad image anyway.
