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 [...]

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 [...]

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 [...]

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 few months [...]

Someone was digging around the ULA publications section, and stumbled on a very interesting paper I hadn’t heard about yet discussing a shuttle alternative for resupplying the space station. While I don’t agree with everything in it, it’s worth a good read. One of the main ideas presented in the paper is a “Payload Bay [...]

I don’t have time to go into detail at the moment, but I wanted to relay an interesting paper that Keith Cowing reported on NASAWatch today. Now, if I were someone at the ESA, I’d probably be taking NASA’s grand plans about Constellation with an appropriate sized grain of salt right about now. But there [...]
