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’ve mentioned, here and in my propellant depot paper, the post-flight cryogenic fluid management experiments ULA carried out on the AV-017 flight this past fall. I don’t have time this morning to comment on it, but I just found out that they have now published some information about the tests carried out and the preliminary [...]

Earlier this summer, I stumbled on a fascinating paper while trying to find some quotes for my Space 2009 Propellant Depot paper. The paper I found, Boom Rendezvous Alternative Docking Approach, written by Joseph Bonnometti of MSFC, discussed an interesting alternative to the standard method of bringing spacecraft together. It also provided an interesting insight [...]

Ok, between the trip to DC for the awards ceremony on Thursday, and taking all of next week off for a long-needed vacation, I’m not quite out of the woods yet. But after that I want to get back into blogging. And I have a few topics I’d like to write about, but wanted to [...]

I’ve been so busy lately that I’m only now getting a few spare minutes to show off some rather cool pictures I was sent a week ago. A week ago Monday, I got an email from Claire Flanagan of the Johannesburg Planetarium in South Africa, asking about some strange pictures, including the one taken above [...]

I only have a few minutes tonight, but part of what’s been keeping me busy lately has been two Space 2009 papers I’ve been involved with (one as the primary author, and another as a very minor coauthor). First, the propellant depot paper I keep talking about: AIAA 2009-6756 Near-Term Propellant Depots: Implementation of a [...]

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, [...]

I just wanted to mention that I’ll be chairing a propellant depot panel at the NewSpace 2009 conference this next week. This year, due to time constraints, I’m going to go for a slightly different format than I did last time. Basically my plan is to give a short 10 minute intro to the topic [...]
