Reddit thread is interesting. Pulled this off there... wow https://www.youtube.com/watch?v=Zl12dXYcUTo

Interesting in that case that the range officer didn't destroy the rocket, or waited a really long time.

In general, Russian rockets don't have the same range safety mechanisms that American and European rockets do.

A lot of people are trying to build mechanical perpetual motion engines, and have failed for thousands of years. Failure doesn't always signal you're doing something right.

These guys, whom i believe to be an investment scam, are the most recent: http://www.steorn.com/ http://en.wikipedia.org/wiki/Steorn They've erased some of the history from their website and interest hasn't been high enough for full exposure of their nonsense. Yet a decade of failure hasn't shut them down. I feel sorry for the people who poured €11 million into them. Never seeing that back.

I had followed Steorn Orbo pretty closely back then, and eagerly awaited for their demo at Kinetica Museum, UK. As expected, they chickened out at the last moment :) This website has chronicled the whole Steorn Orbo saga: http://dispatchesfromthefuture.com/

According to the press conference just now, the range safety officer apparently did send a destruct signal. The signal probably would have been sent very close to the time the rocket hit the ground. In my relatively ignorant opinion, it was going to blow up one way or another. We'll probably get more details later.

Out of curiosity, what does this signal actually trigger?

Usually it's a rope of explosives running up the barrel of the rocket. The goal is to quickly remove structural integrity, and the rocket takes care of blowing itself up immediately.

I had a close friend who worked on this. Everybody in our lab stopped working this afternoon to watch it launch, and to cheer our friend on. Definitely went from "YAY!" to sad really quick. It's been said other places in this thread, but to echo it again: I really feel for all the engineers involved in this. That's got to be devastating. To everybody: failures suck, but big spectacular failure is directly correlated…

I happened upon this website as a result of a Google search re. yesterday's failed launch of the Orbital Sciences venture to resupply the ISS, and this URL appeared as the first search result. I've read your site guidelines, as well as the many comments on this news page, and as a lay person I humbly offer this question, which I hope someone will answer: Why was there no escape rocket atop the rocket's payload module? Was it considered cost-prohibitive? Thanks for your time. Cordially, Steve Logsdon. Post Script: I hope you won't think it patronizing of me to observe that I found the apparent erudition and literacy of the contributors to this web page to be most impressive.

If I remember correctly, the cause of this accident was that one of the nozzles had been wired in reverse, causing it to move differently from what the rocket ordered it to.

In that one the gyroscopes (all 3 of them) were installed upside-down, and what's truly facepalm-worthy was that the guy who did that decided to force them into place:

investigators simulated the improper installation of the DUS angular velocity sensors on the actual hardware. As it turned out, it would be very difficult to do but not impossible. To achieve that personnel would need to use procedures and instruments not certified either by the design documentation or the installation instructions. As a result, the plate holding the sensors sustained damage.

"If you're failing, you're doing something right." I didn't think people said this and meant it. If you succeed, it means you've done the critical things right. If you're failing, it means that you didn't do something right. Or several somethings. Yeah, you can learn from it and do better, and that's great - but that doesn't mean it's a success. It's a failure and - in some cases - a chance to do better the next time…

As I've understood it, it means that the scale of your ambitions is right. Consider a continuum of things that you can do, divided up by difficulty. For some part of it, you allways succeed, for some part of it, it's a mix of sucess and failure, and for some even more difficult part, you always fail. Now in order to succeed at something consistently, you need to master it, which also means that the things you always…

I'm way late on this, but I also think considering the network effect of efforts make direct learning from mistakes more...interesting. There are individuals on the team that very clearly were not responsible for the failure, others somewhat responsible, and perhaps a few directly responsible. This would correlate nicely with your continuum above..

Ahh somehow i missed that blog over the years. Its the kind of things Jon Ronson should do a piece on.

I found his public facebook feed recently. Whole thing is madness. People/friends/family seem to think he really is some kind of big shot. He posts pictures of T-shirts with CEO written on them etc. To me it is and always has been an investment scam.
