Orbital CRS-3 Rocket explodes t+6 seconds

Our backward march continues... hey, Russia, can you help us with our rockets? We don't have any more German scientists from WWII.

Well...Russia could be part of the problem. As far as I understand it, these rocket engines being used in Cygnus are old refurbished engines from the Soviet N1 moon rocket program.

They have had some issues with failures during testing in the past. One for example determined to be caused by "kerosene fuel leak in engine manifold due to stress corrosion cracking of the 40 year old metal". Here's a Popular Mechanics article if you want to read more.

Chinese chips in American hightech weapons.

Russian engines in American space rockets.

What's next? Northkorean burgers at McDonalds?

I had thought about getting a job at Orbital Sciences... Now I'm not so sure...

In any case, Elon Musk is no doubt stroking his white persian cat and grinning maniacally.

Yea, set up here on the Va border hoping to see a rocket launch....

The way I understand the company has decided to produce their own engine, rather buy old stocks of Soviet NK33s or new Russian RD180 series engines.

Plus they have outsourced some work on the first stage to the Southern Design Bureau in Ukraine.

You would really base an employment decision based on this one incident?

Orbital is quite successful in most of the stuff they are doing. If I wanted to get into the purely civilian market, Orbital would be one of the first I would send my resume to.

I hate to break the news to everyone but we really need to get these astronauts resupplied soon. This set back could lead to a major international incident if they start battling over the last roll of toilet paper.

Could well be.

My understanding is that refurbished Russian engines were used.

Yes, old (1970s Soviet Lunar program) NK33 engines refurbished by Ukrainian Yuzhnoye Design Bureau to the Air Jet 26 standard.

I think we can just be glad it wasn't a manned mission. It's a huge step backwards for commercial space travel, but only a step.

The simple fact is that rocket launch failures happen, even with generally well rated engines, and there are always kinks when it comes to designing and using a new launcher, such as unanticipated pogo effects or problems with the piping. Considering it had 3 prior successful missions in space, it is doing pretty good (the Falcon-1 for example had 3 failures to 2 successes)

As for the NK-33. They are generally considered to be a very good engine design with great specific impulse. They themselves were not the reason why the N-1 project was such a colossal failure, it had to do with the clustered design.

We better stock up on candles, for when the grid goes down.

Check out NASA's record with rockets back in the day, seems like every other one blew up on the pad! These are new companies getting into rocket design, and it appears they are taking short cuts that aren't working out real well. But we have had plenty of Atlas and Titan rockets do the same thing sadly.
