Well that was exciting Thanks NSF for the great coverage as usual!

[simonbp]

Ugh. Chamber pressure was the reason for the scrub.

Hope that doesn't mean an engine change. If so, May might be right out...

Fantastic coverage Chris.

Ditto.

[psloss]

Strongback to be raised.

In progress, almost done.

Disappointing, but good safety measures.  Better a safe abort on the pad than a spectacular failure.... a big Ka-boom type of failure.  Now they can turn it around and try again.

[Rocket Science]

Gwynne said 50/50 chance of launch. Launch team sounded smooth…

[clongton]

The launch control team sounds very professional. At Abort they just went thru the numbers. Any emotion was suppressed under procedure.

[JBF]

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

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

Likely an overly-tight limit.

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

Based on the two previous launches, I predict it's just an overly-conservative limit that will be relaxed in the future...

Tweet from Musk.

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

Ah, new(er) vehicle: learning curve!

[corrodedNut]

Engine 5 is center engine?

Correct

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

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).

Great coverage. Looking forward to the next attempt.

[Rahkashi]

Sometime today or later? I thought the next window was Tuesday at 3:44 am?

Wow. Record time for abort analysis.

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

That was the SpaceX loop, on NASATV. The SpaceX feed immediately cut in with commentary after 15 seconds. And now it's offline.

Tuesday May 22 at 3:44am is the next launch attempt date & time.

Thanks for the great coverage Chris!
