Coronavirus has nothing to do with it.
SpaceX said the launch of the Falcon-9 launch vehicle, which was supposed to launch another batch of Starlink satellites yesterday, was again delayed.
The start-up procedure was interrupted automatically when, during the engine check, the system found that the control data had exceeded its normal limits.
This is the second transfer of the launch, originally scheduled for March 14. The date of the next attempt is still unknown.
