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 [...]

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 [...]

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 [...]

[Ed: I'm pretty sure I've used this argument before, but didn't see it on the blog, so I figured I'd put it down in writing even if it ends up being repetitive.]
One of the most common criticisms I hear of propellant depots is that we can’t “put unproven technology on the critical path to our [...]

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 [...]

I think most in the commercial space industry would agree that COTS is one of the best things the government has done to help promote commercial space in a long time. While I think that overall this program has been run pretty well by government standards, some recent discussions on a few threads at NASASpaceflight.com [...]

I don’t know for sure what it is, but I just don’t have a lot of mental bandwidth anymore these days. I’ve realized that I don’t have as much time or energy to pour over all the details of an idea before posting. Especially when a lot of these ideas may be a [...]

Space Journalist/Blogger Rob Coppinger wrote an article tonight attempting to debunk “The Fantasy of Propellant Depots“, which he makes out to be some sort of religious mantra in the New Space community. I will admit that depots are finally starting to get a tiny bit of the attention they deserve, but that has only been [...]

Here’s one other interesting paper, which was presented at the SPACE 2008 conference a few months ago. As I mentioned in a previous post, I was given a copy of a few of the ULA papers before the conference, but decided to wait until after the conference to write about it. The past [...]

Now that I’ve wrapped up my Orbital Access Methodologies series, I wanted to share some thoughts about the business and market development side of reusable space transportation. Some of this may be old-hat for many of you, but I figured there are probably some who will find this useful and interesting. I was originally going [...]
