Well done! Nice to hear the Dragon-Falcon roar… ;D

The site is busy, but nice and smooth! :)

"Page created in 0.096 seconds with 21 queries"

That's cause we're on super duper servers. Thanks to L2 members such as yourself who cover our hosting costs! (YAY for L2 plug on a busy live thread ;D)

Meanwhile...


This is why we test - to make sure everything works so it doesn't happen on launch day. Optimistic they'll recycle, they did for the last time they aborted for a static firing on a F9.


Today is another test for Chris in preparation for the real thing, too. Edit: seemed fine to me.

cheers, Martin

Initial signs from SpaceX indicate a successful test.

Heard a "good static fire" among the controller chatter; no other details about the engine test yet.

Anyone else know if it went well?

@SpaceX:  "SUCCESS - 2 second burn!"


Excellent, thanks (my Itouch is down). I hope the post-test inspection comes out clean.

Is there a reason why they removed the countdown from the screen at 31 seconds? I thought we were looking at another abort  ::)

Anyways, well done SpaceX. Bring on next Monday!
They removed the graphic so it wouldn't interfere with the viewing frame.


Which is appreciated, I hate huge graphics like that.

Awesome! That was perhaps the closest I've come to a "Shuttley" feeling since STS-135. :)

That looked real smooth, hopefully the data is all in line.  Man this is going to be a long week...

Thank you to all you experts, it makes these historical events come alive. Just wish that more people understood the significance of these new private space programmes. I am a jealous admirer from the UK...go USA and remember what makes you great!

On a related note- can we presume continued venting means no prop offload so far, so not aborted *yet*?

That's safe to assume, but even if they started draining prop immediately, it would still vent for many minutes afterward.

I think the first four words of that sentence are contradicted by the rest of it.

cheers, Martin

Abort went as planned.  Reviewing data.  Controllers have vehicle reconfigured and topped off awaiting clearance from engineering to detank...

And MD just cleared it.

Looked good to me, don't know if it was for the full duration. I did see a reddish-brownish cloud, like you see for nitric acid-based rockets... is that from the hypergolic igniter?

Nah, just smoke looking browner than all the water vapor, coupled with the camera white balance setting.

TEA-TEB hypergolic igniters, according to another site.

I know what they're using, I'm saying that's a lot of smoke to be produced by the small quantity of TEA/TEB used during ignition. On the other hand there's a whole lot of black smoke and soot released when Merlins shut down.

Right, I had forgotten if those TEA-TEB igniters were based (heh) on nitric acid or not. They aren't. And, as you said, it's probably too little to make that sort of effect. It's just the hot brown smoke from kerolox combustion.

Also, doesn't TEA/TEB give a green flame?

Yes, but doesn't mean the smoke is green. IIRC, the smoke was bluish-white.
