I’ll update this after work with some commentary (and sometime in the next week or two, I’ll see if I can upload a video of the session as well). But for now here are the four presentations that were given.
I started out with an introduction to the concept of propellant depots, a short discussion on some of the general technical and business challenges, and then an introduction to the panelists.
Rand Simberg (of Transterrestrial Musings and also of Wyoming Space and Information Systems) gave a presentation talking about some more of the business and policy issues related to propellant depots.
Dallas Bienhoff of Boeing discussed the work he’s done over the past several years on propellant depots, and he also discussed in more concrete terms some of the advantages (both to ESAS and to commercial operators) of propellant depots.
The final presentation was given by Frank Zegler, of ULA. He talked about their thoughts on propellant depots, and some related work they’ve been doing (and will be doing in the near future. Frank had some cool eyecandy for some of the hardware they’ve been building and testing lately for the new Advanced Cryogenic Evolved Stage that ULA is working on.

You and your accomplices make a compelling case. It is just amazing that this wasn’t addressed in say, the 80s.
Accomplices? I believe the term these days is “unindicted coconspirators”.

Good stuff. Thanks for posting it.

Any news on ULA development of the wide-body-Centaur EELV upper stage? Or is it moribund?
Tom,
You’re welcome!
Anonymous,
They’re still working on an advanced stage called “Advanced Cryogenic Evolved Stage” or ACES for short. It’s been going through several iterations, and I’m not sure when they’re actually going to move it into production, but it’s an ongoing project AFAIK.
