Yes, this expensive telescope is there just for taking pictures! Basically, it took the space telescope a whole month to get to that destination... The article mentions it'll take about 4 months to calibrate, the pictures will initially be blurry. I wonder why it would take that long to calibrate.

The article says something about that. I'll summarize for you. Basically, it's like aligning 18 different telescopes - and it's a million miles away. So that brings it down to about 6 days per individual alignment. I'm amazed that they can do it at all. I'm still in the wonderment stage. It's almost incredible that we can GET something - anything to travel a million miles and then position it accurately in space. And then making complex telescopes work and sending pictures back? Great! (I have enough trouble emailing pics to a couple of friends in Europe!) This whole project is genuine "frontier of space" stuff. My hat's off to those who brought it about. Brilliant! "Why does it take so long?" - Because it's HARD!
