Blue Origin Gains Some Useful Experience

…by crashing a test vehicle – Successful Short Hop, Set Back, and Next Vehicle:

Three months ago, we successfully flew our second test vehicle in a short hop mission, and then last week we lost the vehicle during a developmental test at Mach 1.2 and an altitude of 45,000 feet. A flight instability drove an angle of attack that triggered our range safety system to terminate thrust on the vehicle. Not the outcome any of us wanted, but we’re signed up for this to be hard, and the Blue Origin team is doing an outstanding job. We’re already working on our next development vehicle.

Nobody wants to lose a test vehicle, of course, but this can actually be a useful development — as anyone who has read Henry Petroski’s books understands, you learn more from your failures than from your successes. It has always struck me as the wrong approach that Orion didn’t budget and schedule a bunch of simple test vehicles, with potential failures and learning from them in mind. Yes there are test vehicles, but they’re each quite complex and expensive, and the failure of any one of them will be seen as a major black eye to the whole program (regardless of what might be learned).

Fortunately, given Bezos’ ability to fund the project, NASA getting cold feet over COTS or CCDEV after a failure probably isn’t much of a threat to the ongoing efforts he mentions in the post.

Apollo I

I missed the anniversary last week due to other time commitments, but here’s a suitably ethereal shot of the “monument” at Cape Canaveral’s LC-34:

Columbia Report Coming Out

Well this is a surprise – CNN is reporting that NASA will be releasing today the final report on the Columbia accident investigation today. This is not the what-caused-it report, but the what-happened-during analysis. Specifically, the report findings we saw concerned how the breakup progressed from initiation to completion and what can be learned to improve spacecraft design for crew survivability.

Not sure if they’ll give as much detail to the public as we got in a briefing back in January, but if so it’s both fascinating and gruesome. It’s simply amazing what the investigators have been able to piece together from very little information.

UPDATE: Keith Cowing has posted a ton of links to the report and related coverage. Since I’m not clear on whether the release of the report frees us from the embargo we signed up for as a condition of getting the briefing from the invedtigators, I’ll wait to comment on it until I get some clarification.
