In Defense Of Daring

I respond to Jeffrey Kluger’s Branson bashing, over at The New Atlantis.

[Update a few minutes later]

Meghan McArdle says that of course space tourism will continue. The notion that a fatality in a flight test would destroy an industry is pretty stupid.

Also, nothing has changed in the past decade: Alex Tabarrok still doesn’t understand the difference between orbital and suborbital flight, or between flight test and operations.

Branson And Refunds

I’m sure that you’re as shocked as I am that Sir Richard’s statement on Saturday is at variance with reality. I think the technical business term for this is “fiasco.” And I’m angry that it has so tainted the industry, not to mention given the FAA an excuse to regulate, if they wish to.

[Update a couple minutes later]

The real problem is “bad business.”

Pilot Error?

That’s not a statement, but clearly is a legitimate question. If so, he paid with his life.

Also if so, it’s a pretty easy thing to fix. But it still doesn’t explain why they deployed without the command to do so. And we still don’t really know how well the engine performed, or what kind of vibration environment it will provide the vehicle and passengers. At least publicly.

It strikes me as ironic, and a demonstration of one of the major points of my book, that the two main features of the vehicle implemented in the name of safety (hybrid motor, and feathering wings) may have actually made the vehicle more dangerous and less operable. Lynx will be a much simpler system.

In Which I’m Quoted In The Times Of London

This comment was made in the weekend context, when most reasonably assumed that the engine had caused the disaster:

The decision to change the fuel may have been behind the crash. Experts questioned whether pressure from investors might have been a factor in decisions by Sir Richard Branson and Scaled Composites, the spacecraft’s designers, to pursue what many considered to be a flawed design.

“If Sir Richard wants to move forward with his business, he needs to go back to the drawing board,” said Mr Simberg, the author of Safe is Not an Option. “Many in the industry, including me, have been concerned about Virgin’s propellant system for years.”

Obviously, I expect them to continue down the current path now, absent some new engine concern. But my warnings were never that much about safety (though as I wrote on Saturday, the safety of hybrids has been dramatically overhyped), but whether or not it was a good engine from a business standpoint, in terms of performance, operability, turnaround, cost, and getting the vehicle to market soon. Those concerns have not gone away.

A pretty comprehensive story, including history, over at Popular Mechanics. He’s not sanguine about the prospects for the vehicle, though (like me) doesn’t see it as a setback for the industry itself.

What does this mean for New Mexico? A long but useful backgrounder.

[Update early afternoon]

Someone over at Arocket found a video of a previous SS2 flight in which feathers were unlocked ten seconds into the burn (as opposed to nine seconds on Friday). So if it was early, it wasn’t very. Not obvious pilot error yet.

The Antares Problem

A piece at Forbes, quoting Dennis Wingo. I love this:

When contacted for comment, Orbital Sciences spokesperson Sean Wilson refused to be drawn into a discussion of the malfunctioning launcher’s problems.

“Until the investigation is complete, we can’t speculate on what caused the failure,” Wilson told Forbes.

Of course you can. You’re not under a gag order. You’re just using that as an excuse to not do so.

What Happened To SpaceShipTwo?

My thoughts, over at PJMedia.

I should note that I since I wrote it yesterday, I’m starting to think that perhaps a chunk of nylon at cold temperatures aloft broke off and blocked the nozzle, because I’m hearing that the oxidizer tank itself was intact, meaning that it was a combustion-chamber explosion (which would be consistent with the pictures). So perhaps it was a problem with the new fuel. Either way, we won’t know until the NTSB completes its investigation, but either way, I think they have to (finally) take a new approach.

[Evening update]


This article
at The Telegraph is pretty devastating.

I think that the biggest issue at this point is how to stave off demands that the FAA start regulating, and to somehow still extend the learning period.
