Space weather will apparently not be a major concern.

PDF of online SpaceX press kit with updated main image. The second stage has a grey band around the fuel tank, indicating that a long duration mission kit has been added.

SFN: SpaceX to launch classified payload for the National Reconnaissance Office [Dec 9]

End of an era
The planned landing of B1096 at LZ-2 may very well wrap up SpaceX’s time using this site as a landing location for its Falcon boosters.

In an effort to increase access to launch providers at Cape Canaveral Space Force Station, Space Launch Delta 45 decided all launch providers need to return their rocket boosters to landing sites at their launch pads.

SpaceX has been taking the necessary steps to shift its recovery infrastructure away from LZ-1 and LZ-2. The company’s lease for these sites ends on Dec. 31, 2025.

All systems are looking good and weather is 98% favorable for liftoff. Propellant load is about to begin for today’s launch of the @USSF_SSC and @NRO_gov’s NROL-77 mission from Florida → http://spacex.com/launches/nrol77

About eight minutes after liftoff, Falcon 9’s first stage will return to Landing Zone 2 at Cape Canaveral Space Force Station, announcing its arrival with a sonic boom

Assuming that propellant loading is underway, but it's hard to see the frost line from the camera's angle. But we should be able to see the 20-minute vent when that occurs.

This is an RTLS, and it will be the last time a F9 booster lands on LZ-2.

Due to customer request, views of the second stage and event after Meco will not be shown. We will continue covering the booster return to LZ-2.

The SpaceX launch broadcast has started early due to a customer payload.
