Tomorrow, we look like a telescope.
Sorry about the long delay between posts. The Christmas and New Year's holidays have taken up most of our free time, but there has been lots of work going on as well. The most exciting news is that after our first round of photogrammetry, analysis by Jeff, and tweaking of the mirror panel positions, the surface of the mirror looks to be within a tenth of a millimeter of bang on, and the path looks clear to getting it significantly better than that. Since then, the mirror has been lifted off the large invar cone that will attach it to the telescope, and the invar cone itself has been lifted and attached to the telescope. And tonight, when the mirror and back-up structure get lifted and attached, we'll have a telescope that looks darn near complete.
Then comes the minor detail of something at the telescope focus to detect the incoming light. Two cryostats and 10 scientists show up later in the week to start that process. Stay tuned.
