Exciting... But does anyone know any more detail time frame for the hot fire, other than sometime in February?

Offline Chris Bergin

Not yet (as of yesterday), but we'll be eager to know too.

Probably relates to the final cold test in the coming days and the results of it.

I'll be surprised (and impressed) if the COTS 2+ demo goes ahead before July. Similarly I think Orbital's CRS-1 might just about sneak into 2013, but not Q3.

Agreed. Another new vehicle and spacecraft in the mix is very positive.

Thanks YG and Andy! The good thing about these baseline style articles is it usually shakes the tree for more info.

It's already 2013 :o think you meant sneak into 2014.

No, that would be slipping. I think his estimate is Q4.

It's sometimes hard to convey these things with text only! No, I meant 2013, as Lurker Steve said, and in fact I was thinking Nov/Dec 2013, but please do share your opinion on future Antares activities timing... :)

I think that there was a backlog of activities based on the launch site slip. The schedule though seems to be lining up now and I think that the schedule should be close to the projections.

Looking forward to the hot fire test.  Sure the excitement with Orbital will continue to build after that.

This has been bugging me for a while:

Can someone tell me what the "7K" in "7K hot fire test" stands for?

It's short for "7000", which is just a milestone number in someone's Gantt chart somewhere.

Just finished reading Orbital tentatively realign Antares hot fire to next week following scrub, good article Chris. Well ahead of postings at the Orbital site.
The choice of the NK-33 has made me nervous for quite a while, though that hasn't been part of Orbital's reported problems as far as I know.
I decided to inform myself about the original engine by reading up on its history at http://www.aerospaceweb.org/question/spacecraft/q0196.shtml
Since both of ULA's rockets (Atlas V and Delta IV) have had good success with ex- & rebuilt Russian/Soviet engines.
Hopefully Orbital hasn't purchased the jinx attached to this engine that eliminated the Soviet Lunar Program.

Which engine on Delta IV is Russian/Soviet?  And which is one on Atlas is rebuilt?
