nathaniel: thank goodness for hubble.
There was a talk about this last week that I didn't get a chance to hear... Anyway, 63 pointings with ACS is a huge number of observations. I wonder if the 500 images were each one orbit long or if they split each orbit into three (to remove cosmic rays). Either, way, that's something like 160 orbits at a minimum, a huge project.
I like the quote too, "...study the universe when it was about half as old as it is at present, or about 8 billion years ago..." That's, um, a lot of rounding.
One other interesting thing is that it turns out that WFC3 won't be able to do this sort of work with anything near the efficiency of ACS. It doesn't have quite the sensitivity of ACS and is a fair bit smaller on the sky. The latest word is that the NASA director might require that ACS get fixed in the servicing mission. That, of course, would be hella rad because you'd be able to observe in parallel with both ACS and WFC3. Unfortunately, it's not clear how you'd do the fix. It might be a matter of putting all the electronics in a box and slapping it on the outside of the telescope.
Oh, and Anton Keokemoer's office is like 5 offices down the hall from mine.
