The launch of a United Launch Alliance Delta IV Heavy carrying the NROL-71 mission for the National Reconnaissance Office was scrubbed today due to an issue with a redundant communication link between the control center and the launch site.   

The team is prepping for a 24-hour turn around on Saturday, Dec. 8, from Space Launch Complex-6 at Vandenberg Air Force Base. The forecast shows a 60 percent chance of favorable weather conditions for launch. The launch time is 8:06 p.m. PT.

Team Vandenberg is scheduled to support the launch of a United Launch Alliance Delta IV Heavy rocket carrying a National Reconnaissance Office payload from Space Launch Complex-6 on Friday, Dec. 7, with a launch window opening at 8:19 p.m. PST.  

Col. Bob Reeves, 30th Space Vice Wing commander, will be the space launch commander. 

"Team V has put in a lot of hard work for this launch," said Reeves. "We are dedicated to mission success and proud to work alongside United Launch Alliance and the National Reconnaissance Office."

The 4th Space Launch Squadron executes integrated launch operations with a focus on mission assurance for this spacelift mission.  

"Every mission is unique and this Delta IV Heavy launch is a prime example of teamwork with a laser focus on mission success," said Lt. Col. Kenneth Decker, 4th SLS commander and Air Force Launch Director for the mission.

"Our mission assurance technicians and engineers have worked diligently with United Launch Alliance and the other mission partners to reduce risk in order to assure mission safety and security.  The men and women of the 4 SLS are proud to contribute to this important mission."

I noticed someone nearby had a star tracker for their digital SLR. Nice way to keep blurry stars out of your night sky photos. I've seen them for telescopes but I shouldn't have been surprised photogs are also using them.

We were out on our deck on Friday night waiting for the original launch. After waiting for about 45 minutes in the cold air we figured that maybe we got the time wrong, or that maybe the launch was delayed. As it turns out, of course, the launch was delayed until last night. Well, last night we were at a party that had incredible food, live music, and lots of liquid merriment. Then we remembered that the launch was going to happen, so we got in our SUV, and headed home where we have an outdoor deck that is in the perfect position to see most of the Vandenburg launches. We were a bit cold, but knew that the launch was going to be spectacular.....we waited, and waited.....and waited....nothing. We were so disappointed that we had wasted so much time over two nights waiting for nothing to happen. Not sure if or when they are going to schedule the relaunch, but we plan to give it a pass as we're not willing to stand outside again while they "scrub" another launch. Guess we'll have to watch it on Youtube or read about it somewhere else.

Next time you can use the ULA link provided by John Wiley below on your cell phone to monitor live the minutes leading to the launch. Then you'll know if there's a delay or scrub right away. We were near Camino Cielo with three other groups of people. Two groups had cell coverage so we got the live launch status. SpaceX also has a live link for their launches.

Thanks everyone for your up to minute postings last night. I was a bit preoccupied with son’s birthday party winding down when I remembered about the launch at 8:30. I was ready to call everyone outside to watch it while refreshing Edhat on my iPhone at my street corner until I read the post that it was scrubbed. Launches like these make it look like a sunrise is happening while looking up Garden St.

No date set still. "...unexpected condition during terminal count at approximately 7.5 seconds before liftoff."

ULA's site said there could be a small adjustment to the launch time due to the 13-minute countdown delay experienced this afternoon.

Is it likely to be interesting to watch? I missed the last impressive launch.

Spy satellites are usually in high-inclination orbits, so my bet would be a very southerly trajectory.

Yes, my guess is it will be cool to watch the brilliant flame when it clears the horizon. Maybe being 22 minutes earlier the trail will enter sunlight and put on a show when it nears orbit? Anyone here know the launch path and geometry of that offhand?

Are they evacuating Jalama for every launch or have they decided that's overkill now?

These launches are so great for Lompoc. We are fortunate that we can see these SpaceX and United Launch blast-offs so close to home... If you can, go up on Harris Grade and watch one.
