Less Curiouser and Less Curiouser

The US spent $2.5 billion sending an amazing robotic explorer to Mars and has now shut it down for no good reason. And what bad reason do they have for shutting it down? Well, as far as I can tell they shut the Curiosity rover down because they don't want black people to have health care. No, I don't understand it either. As far as I am aware the mars rover was not giving medical treatment to black people on mars.

UPDATE: They didn't actually shut down the Curiosity rover.  I mention this fact despite the fact that it is a fact and we appear to have moved beyond such petty considerations as a society.
