The launch of a SpaceX rocket may be visible across the Southeast and Mid-Atlantic on Tuesday evening — as the rocket ascends high enough to be seen by distant skywatchers. The launch time window is set for 6:07 to 7:07 p.

The company plans to send its Falcon 9 rocket on a mission to deliver 21 new Starlink satellites into low-earth orbit. The satellites are used to expand Starlink’s global high-speed internet network. SpaceX said 13 will have direct-to-cell capabilities.
