Let's go!!!!

Forty second hold is stubborn.

Clear the hold!

Something keeps tripping around. 0:29

It's impressive they can hold and reset many times under 40 seconds tbh.

At least they could pan to Kate Tice while we're waiting to scrub.

Go go

Not happening.

0:28 again.

Looks like a scrub. Dang it

Laaaaame

Damn

Officially scrubbed for today

What a tease.

Soooo, was that perfomative practice or a real attempt to launch?

Haven't they had some other quick connect issues recently?

They launching it tomorrow then?

Someone didn't do their job.

Sounds like the DSS was tripping a sensor in the flame trench every time it kicked on.

The hydraulic pin holding the tower arm in place did not retract.

If that can be fixed tonight, there will be another launch attempt tomorrow at 5:30 CT. https://t.co/DJAdvDYQpH

Just send someone up there with a sledgehammer

Good thing they had a sensor on that pin. That could have been a very messy and explosive launch.

When the sun comes up that's going to be an electromechanical pin.

0530 or 1730?

1730. They delayed until 1830 today before scrubbing.

I was working and keeping an eye on the sky but I am glad it was scrubbed so I can see it tomorrow. There are a lot of thunderstorms on the forecast tomorrow afternoon so hope that doesn't become an issue.

For want of a pin a kingdom fell. Or something.

Dam.... Elon needs get his guys to go buy some WD40

Overnight teams worked on the locking pin for Tower 2's ship QD arm the reason for today's scrub. In the GIF, you can see it move in the center of the screen. Hopefully, it's fixed and signed off for Flight 12's second attempt.

I'm reminded of that Soyuz access platform the Russians had roll back out on it's rails during a launch last year because they didn't lock it back out of the way correctly? Simpler, sure, but I'm glad they didn't 'risk it' yesterday if this wasn't secured.

'It's the little things...'-REK.

If y'all haven't watched the third episode of CSI Starbase's stage zero series you really need to commit the time to it. Apparently SpaceX is using an in-house custom methalox ?burner? ?engine? to instantly vaporize liquid nitrogen as an air supply to pressurize the water deluge system. Zack previously referred to this thing as a baby raptor. Fly over pictures from McGregor reveal that SpaceX probably refers to this thing as a Grackle.

Using a methalox power supply for a compressed air source is crazy work.

NSF live stream is talking about You'll Thank Me Later and JRTI transporting components and ships/boosters from Starbase to the Cape.

In your experience, what is a reasonable transit time between those? I assume they'll go down the ICW the whole way, is that accurate?

May be a dumb question but why can't they recycle what fuel they loaded onto the ship yesterday?

I've never spent any time in the ICW so honestly I couldn't answer that question with any degree of certainty. I don't even know how fast those push boat guys run in there.
