The California-based spaceflight company was scheduled to launch another batch of its Starlink internet-beaming satellites and two satellites for BlackSky on a previously flown Falcon 9 rocket at 4:18 p.m. EST (2018 GMT) today from Pad 39A at NASA's Kennedy Space Center in Florida. However, the company chose to delay the launch attempt, and a new date has not yet been set.

"Standing down from today's Starlink mission; team needed additional time for pre-launch checkouts, but Falcon 9 and the satellites are healthy," SpaceX tweeted on Friday afternoon. "Will announce new target launch date once confirmed on the Range."  

The "Range" SpaceX mentions is the Eastern Range, which is part of the U.S. Space Force and is the entity that oversees the launches from Florida's Space Coast.  This Starlink launch is one of two launches SpaceX has on the Range's calendar for this week.
