Regarding Hubble, I was convinced they wouldn't be able to afford to do the repair robotically anyway, and after reading an article on the subject by Bruce Moomaw through Space Daily (The Case Against Hubble) I have reluctantly come to the conclusion that Hubble is just not worth saving.

We have 2 instruments intended for Hubble that could easily be sent up on their own, either as a pair on one platform or separately. Possibly the most important instrument on Hubble is the spectrograph, and it has already failed. It would be just as easy to send a new one of these up as a separate mission as well.

You could do all of this for less than the $1.6B US minimum price tag of the repair option. I'm sorry, but it just doesn't make economic sense.

I will be sorry when I hear it has deorbitted.
