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.

Fewer Words, Longer Books

rigorous, quantitative analyses to confirm the trend, so what I really have is a suspicion based on inference, internal logic, and anecdotal evidence; however, it struck me as a sufficiently interesting observation that I should desire to share it with you.  The trend is this: the English language is losing words (ironic, considering our post about word creation), and is using more of them to compensate.

Conservation and Cycles

In any closed system, quantities must be conserved.  Thermodynamics inform us that energy is conserved.  Linear and angular momentum are both conserved, whether we’re looking at billiard balls in a Newtonian paradigm, or photons in a quantum system.  Special relativity expands conservation even further to the equivalence between matter and energy.  In a closed system, where nothing can escape, quantities are inevitably conserved.

Thought Out

of my favorite books growing up were How Things Work, and its sequel.  I read books on circuit design and simple machines from cover to cover, multiple times, and I saw engineering as the ultimate in thinking everything through.  In my head, anything made by human hands was the product of a thorough process of dimensional and material optimization.
