Space Debris Economics

Why should a private company make a business out of space debris removal?  Alternatively, can space debris removal be made into a viable business model?  This is one of those complicated questions that I recently saw reduced to a gross oversimplification in a news article.  There were a lot of issues with the article, and I don’t want to dwell on it, but I think the biggest problem was its underlying, unstated assumption that the only viable business case for space debris removal as a commercial service was if the government was the customer, or regulated private space industry into becoming customers.  The underlying argument of the article, therefore, is that there is no viable business model based on space debris removal.

TESS: Transiting Exoplanet Survey Satellite

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.

Where’s the Science Fiction?

Broadly, I classify my writing as speculative fiction, which includes the genres that are typically shelves under both the fantasy, and science fiction categories. Yet, you will notice that the majority of my works, both published so far on the site, and in progress, fall in the fantasy genre. Considering that my "real" job involves working with advanced, experimental satellites, that might seem somewhat counter-intuitive, and indeed I've gotten a lot of questions recently about why I don't write more science fiction. So, I've decided to try to provide an answer, other than the fact that I'm not nearly as skilled or imaginative, to why I'm not the next Isaac Asimov.
