SpaceX is preparing for its final mission supporting the National Reconnaissance Office in 2024.

The NROL-149 mission is targeting liftoff on a Falcon 9 rocket from Space Launch Complex 4 East (SLC-4E) at 5:20 a.m. PST (8:20 a.m. EST, 1320 UTC).

Spaceflight Now will have live coverage beginning about 30 minutes prior to liftoff.

The Falcon 9 booster supporting the mission will touch down on the SpaceX droneship, 'Of Course I Still Love You,' a little more than eight minutes after liftoff. If successful, this will be the 114th booster landing on OCISLY and the 384th booster landing to date.

Onboard the rocket are an undisclosed number of satellites, which are believed to be Starshield, the government variant of the Starlink satellites.
