NROL 76 (USA 276)

NROL 76 is an not yet identified payload for the NRO to be launched as the first NRO payload on a SpaceX Falcon-9 v1.2 rocket. The target orbit is not known.

The published NOTAMS show a launch to a ~50 orbit with a non-planar launch window. It is a LEO mission. This kind of orbit is not used by any known NRO mission before, so likely it is a new type of payload or an experimental one-off payload, perhaps similar to the NROL-21 (USA 193).

The observation of an yet unidentified object might hint to an orbit similar to the ISS orbit.

The delayed deorbiting of the second stage might provide a hint on possible secondary payloads.

The SpaceX Falcon-9 v1.2 launch was contracted via Ball Aerospace, which is likely the builder of the satellite.
