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 [...]

Or at least that’s how Stephen Flemming put it on Twitter regarding Jeff Greason’s presentation at the Augustine Committee meeting today in Florida. To be fair, the rest of the subgroup also did an amazing job, especially Chris Chyba’s wrapup near the the end, where he made the case forcefully that becoming a spacefaring civilization [...]

Last week, right after I finished sending my propellant depot white paper in to the Augustine Committee, I got contacted by David Shiga of New Scientist with some questions for an article he was writing. The article is now available online, and while it probably doesn’t say much that is new for most readers here, [...]

Mr X over at ChairForce Engineer has one of the best Apollo retrospectives I’ve seen this week (which is only helped by linking to one of my other favorites from this week, by Reason’s Ron Bailey). Their points are well-taken. At some point, we’ll have evolved our space transportation system to the point where we [...]

Ok, two weeks ago, I mentioned that the “pre-depot” dual EELV launch concept my friend had passed to me could be adapted to do manned lunar missions. Lunar missions are a lot easier to close if you assume a depot in LEO (and even easier if there’s also a small depot at L2). But it [...]

I noticed during the DIRECT presentation at today’s HSF public meeting, that they were asked why they would need an HLV if they had depots. Now, I didn’t hear the exact question, since I had a phone call come in just a few minutes earlier (ironically enough from one of my friends in the depot [...]

I’ve been busy a lot lately (between this, this, this, and having friends in from out of town for the holiday), so I hadn’t had a chance until now to reply to Mark Whittington’s correspondence with me (found here). A majority of his reply was arguing against stuff that I had never said, or making [...]
