The thing is, NASA wants to go to Mars, but before they can even think about that, they really should think about going back to the moon and using that as a stepping stone and preparations for the 6 month journey to Mars. Everything we would need to test for Mars can be done on the moon and also possibly set up an underground base on the moon.
I am not sure if it's final but it does make me angry. The telescope is way behind schedule and at around 4x the projected cost. What is really upsetting is that they plan to end Hubble in 2014 (ditching it into the ocean) which means if they don't extend hubble for another few years, we will have to go 3-5 years without a space telescope.
