SpaceX successfully launches 56 Starlink satellites on Falcon 9 rocket.

SpaceX launched 56 more older-generation Starlink satellites on Friday, as the company troubleshoots problems with a batch of upgraded Starlinks launched last month. The Falcon 9 rocket successfully deployed the 56 satellites into an orbit about 200 miles above Earth. SpaceX has swapped out the second-generation Starlink V2 Mini satellites for groupings of older Starlink V1.5 spacecraft on the next two Falcon 9 missions. SpaceX has launched 4,161 Starlink satellites to date, and 3,858 of the spacecraft are currently in orbit.
