I'd say some people are probably a bit under pressure right now. Which might not be a bad thing.

NASA and management pressure rarely ends well.

Excerpt from nasa.gov:

The agency plans to begin live coverage on NASA Television, the agency’s website, and the NASA app approximately 30 minutes before the hot fire. The team will refine the timeline as it proceeds through operations. NASA will provide updates on the operations and the target hot fire time at @NASA and the Artemis blog.

So tomorrow, at 3PM EUS time, if everything goes well.

The "EUS" (never heard of that... maybe European something?) made me think this was going to happen about now, but actually it is at 1400 CDT, 1500 EDT, 1900 UTC, or in about 4 hours from now.

No Eastern US time. It was on NASA website. Now there's probably another acronym (EST?)

Should be in 4 hours from now.

EST is Eastern Standard Time. Since last weekend, the US is on Daylight Savings Time (DST), which makes it EDT. The four Continental United States (CONUS) time zones, are Eastern, Central, Mountain and Pacific.

Small hint for all people who get confused since the USA also switches time at different days of the year as Europe - you can configure windows 10 to show also two other other time zones if you hover your mouse over the clock in your taskbar.

That's a very good hint thanks, so is it :

UTC-5:00 - East - USA & Canada ?

Plus the error of ~20 seconds I recently noticed Windows 10 has... ?‍
Anyway, any bets for the length of the burn today? I say full duration... or it stops in the same place as the first one. ?

I think it will be a full-length burn without any significant anomalies.

Or some Boeing managers will be replacing the LC-39 flametrench bricks for the next decade.

Like I said the other day, I had two computers on my desk, both Windows 10, both connected to Internet, and proudly displayed a 2 minutes difference... Windows clock is not super-accurate...

Judging from the stream delay, it looks like T0 was moved back 1 hour.

I'm not too surprised, it is quite a complex machine, maybe too complex... we'll see...

Finally an update!

T0 currently at about 2030 GMT.

I want their 3D models of the SLS ?

 

[GLS]

Were using engines from the Space Shuttle, that launched John Glenn and Hubble missions, etc...
I wonder why they don't mention where those "historic" engines will end up...
