Heading out there to watch tonight for sure, should be quite a sight in the dark night sky.
Any updates when it comes to weather prognosis? Last I heard was 70% chance of launch.

It appears they have just scrubbed due to weather preventing MST rollback.

Oh you bet!!
Atlantis was excellent. The next time we'll be out this way it'll be for humans-on-a-Falcon or SLS, or for the first KSC launch of Falcon Heavy
LOOONNGG flights home now and back to work Monday morning
'Bye for now.

Actually SFN timestamp on the scrub shows they were first by way of notification. They have EELVs in the bag, credit where credit's due.
I'm sure everyone is thankful for RG to post in a speedy fashion.
PS How's the weather looking today?

Actually I see ULA are currently go pre their latest release, so we'll change the call signs on the thread.

Thanks for the update, Launches are very good at filling boring cargo transfer days on the ISS.

Cape Canaveral Air Force Station, Fla. (July 15, 2011) – A United Launch Alliance Delta IV stands ready for launch at Space Launch Complex-37 with the Air Force’s Global Positioning System (GPS) IIF-2 payload. Launch is scheduled for Saturday, July 16 at 2:41 a.m. EDT. GPS IIF-2 is the second in a series of next generation GPS satellites and will join a worldwide timing and navigation systems utilizing 24 satellites, in six different planes, with a minimum of four satellites per place, positioned in orbit approximately 11,000 miles above the earths’ surface.

...

I see lots of references to the GPS constellation consisting of 24 satellites. That's actually the minimum number occupying the so called prime orbital slots. Twenty four are required for meeting a geometrical requirement related to the specified system accuracy. At this moment, there are 31 satellites transmitting. One is set unusable so 30 are available for use.
More specifically, the Air Force recently announced the completion of the 24+3 GPS constellation. The system operators were flying the 'extra' satellites in proximity to the prime slots. Although that configuration maintained a backup posture, the extra satellites didn't materially contribute to constellation effectiveness. About a year ago, they began repositioning six satellites to provide better coverage in the mountain valleys of Afghanistan.
There are also a few residual satellites available for emergency service.

Any news on the Launch? Weather doesn't look any better today (at least for me, being no weather expert
) than yesterday. I was surprised to read that they did the roll back today...

60 percent chance of favorable weather. Still a long time to launch yet.
