I understand there was a problem with ground-support equipment this morning. Did cryo tanking begin on time?

No. Weather held it up. In works now. Lots of leaks at the pad...but nothing serious from what the reports are claiming (S0007 shift status updates via L2). Might do an article.

Looked pretty funky out there a few minutes back...

Main thing is "The STS-120 S0007 LCD is currently proceeding on schedule according to the bar chart..."

Just some showers going through and maybe a few lightning strikes, nothing close to worrisome...

More importantly, it looks like one of the tankers (LH2, if I'm guessing correctly) is leaving the pad currently.

Tanker truck now leaving, so I guess PRSD load has finished 1 hour and 50 minutes behind schedule due to weather:

T-19 hours and COUNTING for 8 hours!

Quick rundown of what's coming up during this countdown:

* Final preparations of the shuttle's three main engines for main propellant tanking (10 p.m.)
* Begin filling pad sound suppression system water tank (3 a.m.)
* Close out the tail service masts on the mobile launcher platform
* Begin star tracker functional checks (5:50 a.m.)
* Pad sound suppression system water tank filling complete (6 a.m.)

Wonder if the lighting is bright enough to see the water tank overflow when it happens before dawn.

On the technical side, but very live info based on L2 S0007 live updates:
