Six deployments occurred about 13 to 43 minutes after the launch, and Spaceflights will command its own deployments over a period of six hours, the release said. The mission set a record for the largest single launch of satellites from US soil, the release said.
SpaceX has successfully deployed four microsats and a pair of Spaceflight free-flying deployers in orbit. This ends SpaceX’s role in today’s mission, which is now in the hands of Spaceflight's free-flyers to release 60 more satellites in the coming hours. https://t.co/paq40MckXspic.twitter.com/xTKitu3Jhp
