If you have any interest, I highly recommend reading this. It&#x27;s not marketing fluff; it has a creative and (seemingly) complete vision and well-thought-through planning, and is clear, concise, and detailed. Maybe someone who follows these issues closely will already know much of it (or maybe not; I have no idea), but it is an education for me and by far the best thing I&#x27;ve read on the subject.<p>For example, the three phases in the title are defined not by physical locations or technological developments, but by dependence on Earth:<p>* Earth Reliant<p>* Proving Ground: R&amp;D in &#x27;cislunar&#x27; space<p>* Earth Independent<p>Maybe that&#x27;s old news to space geeks, but it&#x27;s new to me and shows an effort to carefully conceive of the mission.
