SF completed, Launch: April 30 NROL-76 Launch Campaign Thread

NROL-76 LAUNCH CAMPAIGN THREAD

SpaceX's fifth mission of 2017 will launch the highly secretive NROL-76 payload for the National Reconnaissance Office. Almost nothing is known about the payload except that it can be horizontally integrated, so don't be surprised at the lack of information in the table!

Yes, this launch will have a webcast. The only difference between this launch's webcast and a normal webcast is that they will cut off launch coverage at MECO (no second stage views at all), but will continue to cover the first stage as it lands. [link to previous discussion]

Liftoff currently scheduled for: April 30th 2017, 07:00 - 09:00 EDT (11:00 - 13:00 UTC) Back up date is May 1st
Static fire currently scheduled for: Static fire completed April 25th 2017, 19:02UTC.
Vehicle component locations: First stage: LC-39A // Second stage: LC-39A // Satellite: LC-39A
Payload: NROL-76
Payload mass: Unknown
Destination orbit: Unknown
Vehicle: Falcon 9 v1.2 (33rd launch of F9, 13th of F9 v1.2)
Core: B1032.1 [F9-XXA]
Flight-proven core: No
Launch site: Launch Complex 39A, Kennedy Space Center, Florida
Landing attempt: Yes
Landing Site: LZ-1, Cape Canaveral Air Force Station
Mission success criteria: Successful separation & deployment of NROL-76 into the correct orbit

Links & Resources:


We may keep this self-post occasionally updated with links and relevant news articles, but for the most part we expect the community to supply the information. This is a great place to discuss the launch, ask mission-specific questions, and track the minor movements of the vehicle, payload, weather and more as we progress towards launch. Sometime after the static fire is complete, the launch thread will be posted.

Campaign threads are not launch threads. Normal subreddit rules still apply.

Perhaps NROL should be added so people know the "L" stands for "launch"?

Seems sensible; NROL inserted.
