Antares-Cygnus ORB-2 ISS launch


Recommended Posts

Oh ####!!

Exploded at T+6 seconds. I assume another AJ-26 failure, but this time not on a test stand.

Significant property and vehicle damage. No personnel in danger.

They're trying to get RD-180's from ULA again, with little luck so far. Better rethink that as they need a replacement engine a LOT sooner than messing with ULA and possible anti-trust lawsuits will get them.

With pad and transporter-erector damage one wonders if they can continue. Cygnus on Falcon 9?

Could be the end of Antares.

This looked like an engine failure. They've rejected some of these Russian motors before, and 2 have self-destructed on the test stand.

Earlier they said they want to replace them with RD-180's purchased through ILA, but the latter wouldn't sell them before. And obviously, it needs a different engine.

A NASA suit mentioned some Cygnus duplicate cargo, especially a nitrogen tank, will be stuffed into Dragon CRS-5 which is on for Dec. 9. He also said it could be rescheduled, but didn't say left or right.

The media's also catching on to AJ-26 being a refurbed 40 year old Russian NK-33 engine. That could get interesting on the Hill.

It used the Soviet era N1 engines that only had failures in its lifetime? Have these engines ever been used successfully? :p

 

Edit: What DocM said.

They've flown 10 refurbed NK-33/AJ-26 engines, 2 demonstration flights and 3 CRS missions, and they've lost 2 on the test stand. If only one failed yesterday that's 3/12 or 25% that have unzipped themselves. Dunno how many failed quality checks.

Russia restarted production of NK-33 and is flying them on the Soyuz-2-1v.

One Soyuz-2-1v stage blew up on the test stand due to a "software error," one test stand burn stopped 52 seconds prematurely and there has been 1 launch success.
