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 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
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
On Avoiding Some of the Mistakes of Apollo
Today is the 50th anniversary of the Apollo 11 moon landing. With a blog named Selenian Boondocks, I figured it probably made sense for me to say something. Earlier this year, thanks to some good advice from several friends, I … Continue reading
FISO Telecon Lecture on LEO Propellant Depots for Interplanetary Smallsat Launch
Today I gave a lecture on the Future In-Space Operations Telecon Series on the idea of using LEO propellant depots for interplanetary smallsat missions. Here’s a link to the archive page, which has both the presentation itself and an .mp3 … Continue reading
Research Papers I Wish I Could Con Someone Into Writing Part I: Lunar ISRU in the Age of RLVs
One of the things I’d love to do if I were successful enough at Altius to afford it would be to sponsor graduate-level research into space technology, business, economics, and policy topics that I’m interested in. Not just because I … Continue reading
Random Thoughts: The Difference Between a Base and a Settlement (by Doug Plata)
There was an interesting comment by Doug Plata a few days ago that I wanted to repeat as a blog post. Background was discussing the idea of long-term stays on the Moon, similar to my old Lunar One Way to … Continue reading
Random Thoughts: Throwing the Moon a Bone
[Note: This blog post was originally planned to be something significantly longer, triggered by one of Eric Berger’s recent Ars Technica articles. But running a bootstrapped startup gave me the choice of waiting until this was totally irrelevant, or saying … Continue reading
SpaceX Mars Plans: Jon’s First Take
I’ve had a lot of friends ping me today about my thoughts on Elon’s Mars talk today. I was in a meeting when it happened, and literally was pinged by half a dozen people during the meeting… Now that I’ve … Continue reading
The Slings and Arrows of Outrageous Lunar Transportation Schemes: Part 4–Propellantless Horizontal Soft-Landing Methods
As mentioned previously in Part 2 of this series, one of the key elements in establishing a lunar beachhead is developing ways to safely and affordably land payloads and people on the lunar surface. In Part 3, we discussed a … Continue reading
