Speculation that SpaceX are now targeting 7.40pm Eastern / 11:40pm UTC, i.e. the end of the launch window.
Targeting the boat? Time to hit it then and head to the bar...

Anyone else having trouble with the live stream? I'm behind a VPN in China so that might have something to do with it.


TIA

youtube is banned in the people's republic of china, sorry

That's not it, though -- I am seeing the same thing in Canada. The problem is that the launch has been delayed, likely due to some boater deciding to enter the exclusion zone.

SpaceX isn't going to reuse a single engine.
That's NOT how it works.
Rockets are engineered. Tested before flight.
You don't introduce a higher risk item and see if that works.
Its not enough to see if it works.
It has to work with sufficient margins.
Just because a Falcon 9 rocket can loose an engine, doesn't make it OK to loose an engine and the other 8 make up for the lost thrust.

For instance if SpaceX has engine losses it will impact SpaceX reputation in front of DoD and NASA for crew and other high value payload launches.

SpaceX will do ALL of their homework. When they fly reused engines, it will be the whole reused first stage, with whatever refurb needed. SpaceX isn't going to launch unless they expect a fully successful launch, all 9 engines perform perfectly throughout the whole flight.

Thats your opinion, not a fact.

And it is simply not true that SpaceX could not reuse an engine and expect it to be fully succesful. After all, thats the whole point of requalification. You test your used engine to make sure it is as good as the new ones. Thus, you do not expect to lose an engine, and there is no higher risk, if your qualification is stringent enough.

But he's correct.

What are the links to the video feeds? Especially the "technical feed" which only has 37 viewers :)

Just go to YouTube and SpaceX channel, it has both hosted and technical webcasts there. The technical one is dropping, at 29 viewers already. Hosted at 667.

Is he? Why? Insider knowledge?

What's the point of stating a fact without some sort of indication why its is actually a fact and not conjecture? Is he saying, which he appears to be, the SpaceX will never take a used engine and put it on a new stage? Or by implication, that once an engine is on a stage, it will never be used on a different stage? ie Unless it fails, it stays on that stage forever. That seems a very ambitious statement to me.

I interpret that as "we have an issue, maybe we'll get it resolved by 7:40pm so lets not say 'scrub' yet". (i.e. hoping rather than 'targeting')

And about that boat: if they were holding for a boat SpaceX would have said that, they clearly said they are holding to review data.

I must be doing it wrong. When I go to the technical webcast, I just get a black screen. Where are the pictures in the update thread coming from?

Those images are from people who are physically at the cape, none of the streams are live yet.

Is the boat away from the area now?
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

The way this lady on Periscope is talking she makes it sound like a propellant load problem. Is there any word elsewhere on that?

There is no boat, they would've called it clearly. It's a so-far-undisclosed technical issue, it seems.

Now there's a countdown on the webcast, supposed to start in 1 hour 32 min

I'm getting a 1hour 30 minute countdown?  I thought the Launch was to happen shortly.
