After completing the first stage, Falcon 9 landed safely on a Space X drone ship in the Atlantic Ocean just under nine minutes after lift-off. 
In the second stage, continued carrying both satellites toward their intended medium earth orbits.  
Space  X gives this information in its Twitter account.

O3b mPower 1 and 2 are created and operated by SES, a Luxembourgish – French satellite telecommunications network company. 
If SPACE X would have been succeeded to launch both Falcon 9 satellites and Starlink satellites on the same day, it could’ve created a record for the quickest turnaround between orbital launches.
