The second attempt to get the GPS III into orbit.
The weather doesn’t look too good but we’ll see.
Pretty much the same launch window as before, coverage beginning at 14:03 UT/ 09:03 ET
Update: As I suspected, the launch is now scheduled for 22 December with coverage starting at 13:55 UTC
Oh by the way a Delta IV Heavy is scheduled to launch the NROL-71 Satellite into orbit at (21 Dec) at 01:00 UTC.
