NASA’s Selection of the Blue Moon Lander for Artemis V
Last week, when NASA announced that they were picking Blue Origin’s National Team to develop a sustainable human lander for the Artemis V mission, what surprised me wasn’t the selection, but the fact that I’ve come around to really liking the decision. Continue reading
Fill ‘er Up: New AIAA Aerospace America Article on Propellant Depots
I was interviewed by John Kelvey for an article on propellant depots, which AIAA just published in this month’s Aerospace America magazine. Here’s an online version of the article for those of you who don’t get the print edition. Also … Continue reading
Independent Perspectives on Cislunar Depotization
I was invited to participate in a workshop this week in Chantilly, VA focused on cislunar propellant depots. As part of the preparation for the workshop, they asked for stakeholder to provide their perspectives on depot architectures, the benefits of … Continue reading
Unorthodox Reusable Lunar Landers Concepts
[Author’s Note: Back in summer of 2019, shortly after Mike Pence announced the goal of having NASA return astronauts to the lunar surface for the first time in over half a century, I had the idea of doing a blog … Continue reading
An Updated Propellant Depot Taxonomy Part VI: Roving Depots
In the last post in this series, I discussed the idea of large-scale depots for human spaceflight applications, which operate in fixed, low-orbits. While the final post in this series will investigate human spaceflight depots that operate in fixed higher … Continue reading
An Updated Propellant Depot Taxonomy Part V: Human Spaceflight Fixed Depots (Low-Orbit)
For this next depot taxonomy post, we’ll finally be talking about what people usually think about when they hear the term orbital propellant depot — larger, cryogenic refueling facilities, focused on enabling large-scale human spaceflight missions, performed by a diverse … Continue reading

An Updated Propellant Depot Taxonomy Part IV: Smallsat Launcher Refueling Depots
After a brief hiatus, I’d like to continue this series with the type of depot I’ve spent the most time thinking about over the last several years, and the first type of depot that really fits the mold of what … Continue reading
An Updated Propellant Depot Taxonomy Part III: GEO Depots
Of the six depot types I’ll be describing in this series, GEO Depots are probably the least fully-baked of the concepts for me, mostly because I’ve only had limited involvement in the traditional GEO satellite world. But I wanted to … Continue reading
An Updated Propellant Depot Taxonomy Part II: Distributed LEO Nano-Depots
For this first type of propellant depot, we have an idea that several of us seem to have independently realized. My company is developing a family of servicing tugs focused on servicing customers in Low Earth Orbit. We realized pretty … Continue reading
An Updated Propellant Depot Taxonomy
After way too many years in the wilderness, the concept of orbital propellant depots and in-space refueling in general, are finally beginning to be taken seriously again in public circles. A couple of examples include: Elon’s announcement that he is … Continue reading
