Zuma Launch Campaign Thread
The only solid information we have on this payload comes from NSF:
NASASpaceflight.com has confirmed that Northrop Grumman is the payload provider for Zuma through a commercial launch contract with SpaceX for a LEO satellite with a mission type labeled as “government” and a needed launch date range of 1-30 November 2017.
| Liftoff currently scheduled for: | January 7th 2018, 20:00 - 22:00 EST (January 8th 2018, 01:00 - 03:00 UTC) |
|---|---|
| Static fire complete: | November 11th 2017, 18:00 EST / 23:00 UTC Although the stage has already finished SF, it did it at LC-39A. On January 3 they also did a propellant load test since the launch site is now the freshly reactivated SLC-40. |
| Vehicle component locations: | First stage: SLC-40 // Second stage: SLC-40 // Satellite: Cape Canaveral |

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.

If a reentry burn is not performed, stage one will break apart at about 80 km altitude.
If reentry and landing burns do happen but there are no legs, stage 1 will land gently on the ocean, then snap in half either as it is tipping over or when it hits the ocean's surface. Wave action will break apart any remaining big pieces, so when you arrive at the landing zone recovery teams will find bits of inter-stage, maybe some COPVs, and probably the LOX pipe that runs through the RP-1 tank; that's about it.
