The space shuttle program was discussed on the FP over the weekend, and someone who worked on the project popped up. I thanked them, mentioning the lens correction on the Hubble as a highlight.
Well, here’s a short but sweet essay about that fix and the Hubble Deep Field image. It reads a little like Buzzfeed multi-page clickbait, but it’s written by an astrophysicist and designed to be an easy read, not a drag-you-through-a-slideshow nightmare, so it’s worthwhile.
