His Own Petard

As NASA continues to chop everything in its budget other than the least cost-effective things–Shuttle, ISS and ESAS–Lou Friedman of the Planetary Society is starting to whine about the loss of space science. But Clark Lindsey points out the irony:

[Dr. Griffin’s plan to delay planetary science programs] would make perfect sense if the CEV program promised to significantly lower the cost of space access and of its utilization. Lower transport costs would make all of those science projects much cheaper to build and operate and would allow for many more science missions than can be flown now.

However, as has been argued often here and in many other sites, flying capsules on Shuttle derived expendables and building a hugely expensive and seldom launched heavy lifter just isn’t going to lower the cost of space very much over what it is now. While halting the Shuttle program now would help to fund a handful of space science missions, it would not help overcome the long term limitations to space exploration and development caused by the extremely high costs of getting to space…

…I’ll note that much of the basic CEV architecture using Shuttle components was born via a Planetary Society sponsored study (pdf) by Griffin and several collaborators before he came to NASA.

Idiot Bureaucrat Defeat

Clark Lindsey has some good news on the model rocketry front–a legal victory over ATFE (a situation about which I’ve written previously). I love this quote from the ruling judge:

The problem in this case is that ATFE’s explanation for its determination that APCP deflagrates lacks any coherence. We therefore owe no deference to ATFE’s purported expertise because we cannot discern it. ATFE has neither laid out a concrete standard for classifying materials along the burn-deflagrate-detonate continuum, nor offered data specific to the burn speed of APCP when used for its ‘common or primary purpose.’ On this record, the agency’s decision cannot withstand judicial review.

AST Conference Blogging

Unfortunately, I haven’t been to the FAA Commercial Space Transportation conference (held every February) in a few years. The years that I have the time, I don’t have the money, and the years that I have the money, I can’t find the time (the latter, which was the case this year, is a better situation). Funny how that works.

Anyway, while I didn’t go, Clark Lindsey did, and he’s got a report from yesterday’s festivities.

Imminent Test Firing?

The count is back on (if you can believe the blog–he says not to, probably to cover his keister). If there were no problems, the test should have occurred by now.

[Update at 4:05 PM EST]

Close, but no cigar:

A few seconds before the engine ingited [sic], the count was held.
They are now safing the vehicle and we will find out soon if they will restart the count and take it all the way to ignition.

It’s sounding like a good thing that they did this test before launch. I think they’re finding out how hard building and flying rockets is.

[Update about 4:30 PM EST]

They’ve recycled the count to T-15 minutes.

I find the fact that they can take the engine all the way to ignition and recycle to a fifteen-minute count a testament to the simplicity of the system (none of this having to empty tanks and recycle to the next day stuff). I’m not sure what it says about reliability at this point, though.

[Update at 4:50 PM EST]

They’ve stopped the count again, but this latest post expands on my comments above about repeated launch cycles, and how far the technology has allowed us to come in that regard. It also provides some explanation of the issues they’ve been encountering today.

Once again, though, it points out that they weren’t ready for prime time when it came to launching (and that these test firing rehearsals were a good idea). That’s what test flights are for, and so far, while they haven’t launched, they haven’t lost anything, either, except some time. Hopefully, this “shakedown cruise” will reveal a lot of things that will give them better schedule reliability in the future.

[Another update a couple minutes later]

It really is a family affair. Note the last name of the commenter to this latest post.

[Update a few minutes later, for those not following the Kwajrocket blog]

They’ve emptied the propellant tanks and are analyzing data, but it doesn’t sound like they’ve yet given up on an engine firing today.

[Late night update]

Two to four weeks (sorry, no permalink–just click on the link to “New Launch Date Update.”)

Problem At Kwaj?

They were supposed to have their engine test a few minutes ago, but they’re on a hold at T-1.

[Update a few minutes later]

They haven’t restarted the count, yet, but Kimbal has some pictures up. Keep checking the main page of the blog for updates.

Heresy

Bill Whittle’s been working on a movie script:

(spoiler alert!)

* Men travelling through space WITHOUT THE AID OF GOVERNMENT AGENCIES!
* People facing extreme risks and DECIDING TO TAKE THEM ANYWAY!
* Puny Earthlings using THEIR OWN MONEY ANY DAMN WAY THEY CHOOSE TO!
* Nuclear Energy being portrayed in a NON-EVIL FASHION!
* BUSINESSMEN and ENGINEERS as HEROES!
* PROTESTORS and CELEBRITIES as JOKES!

Full disclosure: I’ve been kicking ideas around with him over beers and comestibles over the past few months.

Horrific

Clark Lindsey has some more perspective on what a waste of money the Shuttle program is currently, given that we aren’t even flying it (and perhaps even if we were):

* Elon Musk has spent about $100M so far on developing the line of SpaceX Falcon launchers. The first Falcon 9 launch is scheduled for 2007. He hasn’t said how much more money it will take to reach that launch but I doubt it could be more than another $100M.

* Kistler says it needs a few hundred million dollars to finish its fully reusable two stage K-1 vehicle.

* T/Space said it can build a CEV system capable of taking crews and cargo to the ISS for around $500M.

* LockMart once promised to build the VentureStar for $6B. If they had a 100% overrun that would still be less than $13B.
