Keith Cowing just posted a link to a fascinating new pro-Propellant Depot analysis. I was impressed to see who the second coauthor was… When you have one of the leaders of ESAS coming out in favor of propellant depots and commercial launch, that says a ton. Very much looking forward to reading the article. Thanks [...]

So, most of you in the space policy world have heard about NASA’s report back to Congress about how it wants to build an Ares-V classic HLV, but that Congress wasn’t giving them enough time or money, and Congress’ dignified response that “Nu Uh! You can too!” That exchange was annoying, but utterly predictable. What [...]
I just saw something this morning that amused me. Both ESAS and Falcon 9 were formally announced within about a week or two of each other (in September 2005). Four and a half years later, a fully-orbital Falcon 9 is on the pad close to being ready for its first test flight, while Ares-I has [...]

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 [...]
This is poor taste, but too funny not to pass along (I apologize in advance to CxP workers reading this). Upon hearing about another CxP element that’s been supposedly defunded, a NASASpaceFlight.com member (Lawntonlookirs) expressed his frustration by creating the following, slightly modified mission patch for Constellation:
I listened in a bit on yesterday’s Augustine Committee discussion. The debate at the end between Bo and the others reminded me of a point I’ve made a bunch of times on this blog–that when you’re talking about exploration missions, ascent reliability is only a small component of the overall risk. Since I’ve been doing [...]

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 [...]

Just reading some of the comments from the Constellation used-car sale pitch going on in Huntsville today. One of the topics discussed was how Ares-V enables manned missions to Mars. The Marshall guys put up a chart showing that depending on whether we go with NTRs or chemical propulsion, Ares-V could place the needed mass [...]

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 [...]
