Ok, fine Jim.

It still appears Elon has automated the launch sequence so it's all handled by computers.

Just like everyone else

Webcast resumed!

Having some issues with the last loading of Helium. Taking longer than expected to load the helium. We're going to load the rest of the helium, reload the rest of the tank, and then try to launch within the window - PAO

Good luck, guys!

Another 'break' while this happens, so will be a few minutes for this to finish.

I thought the part where he mentioned that they had learned from experience that colder fuel resulted in lower thrust in a prior "campaign" was interesting.

Was that a factor in the lower than expected thrust in the last attempt? I thought that was attributed to something else. I know they had a scrub due to a temperature alarm on a prior attempt.

The clock is holding at T-16 minutes. We are loaded to 97% and it is taking longer than expected to load the final 3%. To prevent fuel from getting too cold, we are detanking. Max will be back on-air at 7:00 PDT / 10:00 EDT / 02:00 UTC with further information. Updates will be posted here as available.

Helium as a pressurant is a love/hate relationship. Helium as anything, for that matter. Mostly hate.

Gotta love Google and WunderMap for their awesome service. Here's an image capture from a minute ago. Weather looks great!

No, it was the reason they aborted after ignition about an hour before that.

It would be nice if the streamed video also showed those times.

Now over an hour into the hold.

1Hr 15Min into hold.

Clock reset to T-55.

If the fuel chills too much, it does not mix at the right temperature and the ISP will be down a bit. In flight 2 this put it just below the low limit and caused a shutdown. They then detanked the fuel to warm it up, retanked a bit later and flew.

Strange, the condensation off the rocket makes it look like a section of the 2nd stage has pealed away. Are my eyes playing tricks on me?
