There was a bit of discussion about dry launch in the space blogosphere in the last day or two. It seems to have started with Jon Goff’s piece at Selenian Boondocks, which Clark Lindsey picked up and expanded on (see the “Fueling a Space Town” post), and was followed up with a post on agile space development by Dan Scrimpsher.

This is an important topic, and I wish that there was some sign that the new management at NASA is paying attention to it.

I would also add, as a response to the commenter who asks in Jon’s comments section, why deliver propellant that has to be transferred as a fluid on orbit, rather than easier-to-handle propellant tanks? It’s because delivering tanks doesn’t offer the possibility of refueling them on orbit, so they’d only be single use. And in-space refueling is a critical technology in becoming a truly space-faring civilization, and the sooner we get on with developing and becoming comfortable with it, the sooner we’ll reach that desirable (at least to me) destination.

[Update at 9 AM EDT]

I was imprecise above. As Paul Dietz points out in comments, delivering tanks doesn’t preclude the possibility of refueling them later, but that wasn’t what the the commenter was suggesting. What I should have said is that it doesn’t advance us toward that (in my opinion) worthy goal, and it was clear from the commenter’s question that he didn’t have in mind tanks designed to be refueled (and it is a significant design issue).

[One more update]

I should have written “…preclude us from refueling from them later,” to respond to Paul’s most recent comment about mischaracterizing what he said.
