Jeff, who happens to be in a really good position to know, clears up a common misconception about the Futron Space Tourism study that I’ve seen made a lot of places (including in the comments section here): This author, being intimately familiar with the forecast, can shed some light on that forecast. A common misconception [...]

It’s been a rather interesting month so far, and I’ve been under a bit too much stress lately to blog much, but I wanted to put up some of the presentations from the Propellant Depot panel I was on at Space Access this year. If I had found the time sooner I would also say [...]

I predict that regardless of the outcome of SpaceX’s inaugural Falcon 9 launch, nobody is going to change their opinion. If it’s successful, Ares-huggers will suddenly begin to understand the concept that a single successful flight doesn’t prove anything about a vehicle’s overall reliability (while most on the pro-commercial space guys will start sounding like [...]

Last year, my family went out to the coast to spend the holiday with a good friend who does finance and project management work for a large aerospace company out there. We’ve been brainstorming various space business opportunities for some time to see if there were any interesting areas that we could both make money [...]

The more I think about the Lunar One-Way-to-Stay concept, the more intriguing it is. Fundamentally, it’s one of the only ways with existing transportation systems to get the cost of early lunar experimentation anywhere near low-enough to be useful and interesting. Ultimately, for thriving two-way cislunar commerce, you need tugs, and depots, and high-flightrate RLVs. [...]

Amid all the recent discussion of the Augustine Committee’s results, Mark Whittington asks a question that a lot of people in Congress seem to be asking: “Why not just pay for the current program since any new program is going to cost more money anyway?” To elaborate, the line of reasoning goes that if the [...]

I didn’t have a chance to watch either of the House subcommittee hearings today, so I’m grateful that Clark linked to the testimonies of the various witnesses. I really enjoyed reading Brett’s testimony, and thought one of his points in particular is worth repeating. To me one of the more interesting points is found at [...]

I want to clean out some of the Skribit suggestions that I’ve been neglecting for a while. Some of these may end up somewhat brief, but I wanted to at least try to be responsive. Drop Tanks to Enable SSTO? I don’t like drop tanks. While they do definitely make the rest of the SSTO [...]

One of the more interesting modules that was originally going to be part of ISS was the Japanese-built Centrifuge Accomodations Module (CAM). The CAM was designed to provide the facilities for testing the impact of reduced and hypergravity–over a range of 1 milligee up to 2 gees of acceleration–on various biological specimens. Tests on these [...]

In light of how well today went at the Augustine Committee, I felt that it would be worthwhile to post the propellant depot white paper that a group of us submitted last week. I was originally planning a much longer paper, trying to make the case that depots were technologically mature enough to be worth [...]
