Mission details:

A United Launch Alliance Atlas V, flight AV-086, flew from Cape Canaveral on Mar 26, 2020. After the second Centaur burn, to geotransfer orbit, the TDO 2 tracking calibration satellite was ejected from the Centaur aft bulkhead. A further burn will raise perigee, putting the AEHF 6 communications satellite in transfer orbit for the US Space Force.
