Yesterday Nick was pretty keen to get the cryostat opened, so that when Matt arrived he could quickly get to all the post-shipping operations (change out optics box legs, inspect for loose screws, etc). Otherwise, odd jobs progressed here and there. I had a few periods of waiting for slow computer operations, so took a bunch of random pictures.
The other thing I haven’t discussed at all, but bears mention in writing, is lunch. Lunch at LDB rocks! We’ve got a great chef serving a manageable number of people. As a result, I stuff myself as much as possible at lunch, to minimize other meals at the regular McMurdo galley. Then, while digesting, I have a good time to write these posts. So you, dear reader, also benefit from my lunch.
