Rather than lamenting the decline of science fiction, we should probably spend time talking about how wonderful Rocheworld is, and why you should absolutely go find a copy as soon as possible. Granted, that may be a little difficult, because it's no longer in print. However, I was able to find a lightly used copy without much difficulty, so I imagine you can, too. Just be sure you look for the complete Rocheworld, and not one of the earlier versions, sometimes titled Flight of the Dragonfly. The book is from back in the days when many science fiction novels were published in short, serialized form in magazines, so Flight of the Dragonfly is about a hundred thousand words shorter than the complete Rocheworld.
As a bit of a side project at work recently, I did some modeling work on TESS, which is a NASA spacecraft that was launched to help search for exoplanets using the transit method (I know, you could never have guessed that from the name's acronym breakdown). Working with satellites as much as I do, this was a really interesting project, because it was quite distinctive in its orbit and mission architecture from most spacecraft that I get to study on a regular basis. For one thing, it is a remarkably low-cost, robust, straightforward system, quite different from what you often see with NASA programs, which because of their scientific goals are often pushing the very edge of our capabilities and therefore become very complex and very expensive. For another, it utilizes a simply fascinating orbit. Since I've been trying to post occasional in-depth articles on various academic topics, it seemed appropriate to share some of what I learned from that project here.
