Ha ha yeah good ol’ SGP has given me plenty of sleep over the last few years

Let's wait and see, concerning Friday. If they cannot resolve the bleed line problem on the number 3 engine, via cycling or software, they will need to roll the ship back to the Fab building in order to tear into the plumbing. Keep in mind these sort of tanks can only be pressurised and depressed about 6 times before they have to be scrapped, and they have used up 3 cycles already (This info from NASA Spaceflight.com).
If they roll back the next available launch window blows out.

Rescheduled for early Sunday, our time.

NASA is running a special on NASA TV this morning @10am (if my time zoning is correct!) talking about what was learned.

Thanks Dunk, I watched the NASA TV briefing this morning. Still no info on the cause of the problem, but they are changing the timing of the fuel fill start, starting it earlier in the count next attempt.

Dodgy sensor?

Camelopardalis (Dunk) · #47 03-09-2022, 11:18 AM

Looks like Artemis 1 will be ready for a second go tonight at 4:17am AEST.

AdamJL · #48 03-09-2022, 12:22 PM

would be a great fathers day present if it launches tomorrow!

Stonius (Markus) · #49 03-09-2022, 01:44 PM

I don't think I'll be up for that one. :-(

DarkArts · #50 03-09-2022, 05:37 PM

I'll be up. How many times in my (remaining) life will I get to see a Moon launch? I figure it's worth it.

There's a 60% to 80% chance of favourable conditions during the window. The countdown commences at 6:37pm AEST Saturday (with a 2.5 hour hold after which the clock starts ticking). NASA TV full coverage starts on Sunday morning at 2:!5am AEST, but you can watch fuelling operations beforehand from 7:45pm AEST Saturday.

You can also watch via the NASA TV app, which is available on Android, IOS and Windows devices, as well as pre-installed on some streaming boxes (e.g. Fetch, AppleTV).

Not overly excited as there is no indication that they found a cause for the last bleed line problem.

AndyG (Andy) · #52 03-09-2022, 07:18 PM

Does anyone know the course this rocket is taking? Would someone living close to the equator see the rocket firing whilst it's still early morning at their location?

Just asking as I'd seen what appeared to be a Chinese rocket (from some launch info) visible over Townsville last year.

They replaced a bleed hose and sensor line, and re-torqued bolts in that area, so they think they found the issues.

Composite probability of "Go" is 70% at present.

Not sure, but the NASA-supplied graphics depict it as launching North East over Northern Europe.

... and it's "Go" for fuelling the core stage.

I read the sensor was at fault and assume replaced but apparently all the chilling operations are totally fine, and was mentioned that if this sensor fails again, they will just ignore it,, hmmm, must have confidence the chilling operations are all good...
Launch at approx 3:45am AEST Sunday at this stage ...
Weather at Cape Canaveral, Possible storms to the Nth at the start of 'Launch Window' becoming less threatening over the 2hr window !

astroron (Ron) · #56 03-09-2022, 09:28 PM

Anyone notice that the NASA Launch Control engineer saying the time,
which is 5 minutes behind the real time
Is this a deliberate delay in the broadcast

Cheers

DarkArts · #57 03-09-2022, 09:40 PM

He's saying the right time when I hear it ...

What platform are you watching on?

astroron (Ron) · #58 03-09-2022, 09:48 PM

NASA TV.
My clocks and watches and phone all
have the correct time.
Cheers

astroron (Ron) · #59 03-09-2022, 09:51 PM

Its correct now?
