Upgraded Hubble To Be 90 Times As Powerful 194
The feed brings us a New Scientist review of the repairs and new instruments that astronauts will bring to the Hubble Space Telescope next August (unless the launch is delayed). The resulting instrument will be 90 times as powerful as Hubble was designed to be when launched, and 60% more capable than it was after its flawed optics were repaired in 1993. If the astronauts pull it off — and the mission is no slam-dunk — the space telescope should be able to image galaxies back to 400 million years after the Big Bang.

The interpretation of the horsehead nebula is at least consistent (most of the time), but there is still plenty of artistic license being taken.

I was sort of disappointed when I found that out...

Really it's one of the most cost effective missions that NASA can do from a science per dollar perspective

The relevent question, though, is whether its one of the most cost effective things *we* can do from a science-per-dollar perspective. And it's not. $1.5 billion to launch. $350 million a year to keep operational. And for what? Pretty pictures of far away balls of gas and, maybe, if we're lucky, a hint of a large rock orbiting the balls of gas.
Let's bust out the government's $135 billion yearly R&D budget. What could we do with an extra $350 million? Well, let me present you with a variety of options. We could double our R&D spending on malaria and TB, working to save several hundred thousand children a year who die from one of the two. Maybe they're not as photogenic as stars many light years away, though. OK, forget the kids.
We could spend the $350 million paying for open source software to be developed. That would pay for, conservatively, hundreds of projects, or a few flagships with the impact of Apache or Firefox. One of them could even develop stunning vistas from distant galaxies, since apparently people think that is an important use of the taxpayer's dollars.
I'm personally skeptical about solar power but, hey, for $350 million you could fund about a dozen projects a year looking into both radical new materials to use and iterations on the existing stuff, trying to make it cost-competitive with cheap coal.
If exploring new frontiers makes you misty, you could just about double our oceanographic research budget with a cool $350 million. We've pissed away billions trying to get a closer look at a dead environment which is terribly hostile to human life and which might include a few drops of water here and there. Instead, for a few million we could do in-depth study of unique organisms who robust, exciting environment and which most certainly includes water. And if you're the "well we've got to find a way off this rock!" Slashdot contingent who has read one too many sci-fi novels, your $350 billion would also count against improving our ability to survive in hostile environments.
Speaking of ecosystems, want to see if an off-world colony is EVER going to be viable? For $350 million you could restart the BioDome project. If you can solve that issue here, you can always worry about launch vehicles later, but if you can't, then all space research in the world won't get you what you want.
Yeah yeah, I know, I know -- "Space isn't the biggest waste of money in the budget!" I'm sure it isn't, but being less-than-maximally-wasteful is not a ringing endorsement of your favorite program.

Money spent on pure science is usually a good investment because the returns are cumulative. The new knowledge that we gain can potentially benefit the human race in all perpetuity.
E.g. Of the immense amount of technology that gives you the ability to post here in Slashdot large portions was funded by public money. Yes, you could rather have used that money to feed a few hungry people, but I would argue that the human race as a whole would be worse off for it.

That may be true but there also may be benefits in learning to repair what we have, that go beyond merely the "launch and trash" philosophy, i.e. when resources are limited. What kinds of new technologies will be spawned to learn how to repair existing stuff in space and what will be learned I think is just as valuable since sooner or later we will have to learn whether others want it or not.
