Did they figure out why it was scrubbed?

From the link...
"United Launch Alliance chief executive Tory Bruno has said Saturday night's abort was caused by a "bad sensor" that tripped an automatic limit, leading the computer controlling the countdown to halt the launch just before ignition of the Delta 4-Heavy's RS-68A main engines.
"An intermittent signal from a bad monitor caused an automated hold to be triggered ... before ignition," Bruno tweeted."

Due to high winds, launch pushed to Wednesday 5:44 PM Pacific

"ULA is keeping open the option of conducting another Delta 4-Heavy launch attempt as soon as tomorrow, assuming the issue that caused tonight’s scrub is resolved. Launch from California tomorrow would occur at 5:31 p.m. PST (8:31 p.m. EST; 0131 GMT)."

Now they're saying no earlier that Dec 30

I'm sitting at the Auckland airport right now so I'm happy that it got delayed since I'll be home then.
