Have to agree with Chris.

As I pointed out on the other thread, what we can take away from this is that we have a very good vehicle, and a very good team here. All the safety systems worked as expected and the vehicle shut itself down.


I am really pleased by what I saw this morning. If a slightly tight chamber pressure limit is the only issue with this vehicle, that's a good problem to have in my mind :)

Wow. Record time for that failure analysis. Like he was almost expecting it...
That's standard -- vehicle safing is highest priority before concentrating on that on the net.  (Remember the same for Shuttle early on.)

I remember watching the launches of Mercury and Gemini. Almost every launch attempt was aborted to come back again another day and try again. SpaceX is having it's growing pains but to date none of the aborts appear to be for causes as serious as those early days in the 1960's. Assuming the preliminary analysis holds and Range agrees, we'll all be back here about an hour earlier next Tuesday to do this again. :)

Wonderful coverage! Thanks. Back to sleep. If I can get my heart-rate down.

thanks for the coverage great job

They did so well to have such a smooth count. This situation is 100 times better than failing on the way uphill.

We'll see what additional info we can get in L2 and we'll summarize any important elements.

A little bit disgusted by a few comments at scrub, but three people on a site getting hit 160 times a second ain't too bad. Never quote and respond, we moderate and get rid of such stupidity (takes longer to remove the response too).

I really wonder why they can't set these limits straight during test firings. I mean, isn't this what you usually do on the test stand and it's not like they were not testing things.

A bit confusing to me, I mean, you don't WANT these limits to get into your way if in reality things are still OK.

The big question is was a a real issue or a sensor fault.

Likely an overly-tight limit.

Wow. Record time for abort analysis.

Tweet from Musk.

Launch aborted: slightly high combustion chamber pressure on engine 5. Will adjust limits for countdown in a few days.

Wow. Record time for that failure analysis. Like he was almost expecting it...


"I" was expecting it too!  ;)



Thanks for the great coverage Chris! 

Seconded!  Great as always!  Like watching a shuttle launch.

Awesome coverage Chris, I really think this is one of the best websites/forums out there.  Not only for Spaceflight but one of the best period.

No fresh fruit for Don Petit. :(

That was my question. They mentioned my name and all. Quite chuffed!

NTV coverage ends. L2 suggests this is not a major issue and thus looks good for May 22 (the latter is my assumption).

Post scrub presser at 6:30am Eastern.

It takes more than testing; it takes flying before all these potential anomalies can be identified and nailed down. It just takes time. I've been watching launches for many years, and trust me; for a new vehicle, Falcon 9 is doing spectacularly well.

Thanks for that, and for the other comments. Means a lot :)

Thanks also for everyone's patience. I do have a couple of mod running amok on these live threads to keep it clean and on track. It's never personal if you lose a post, it's all about housekeeping.
