SpaceX canceled the launch of the Falcon 9 with a satellite two seconds before launch

SpaceX canceled the launch of the Falcon 9 launch vehicle with the GPS III satellite 2 seconds before launch. The company is broadcasting live.

The launch was scheduled to take place at 21.43 East coast time from the Cape Canaveral Space Center (Florida). Two seconds before the start, the MCC gave the command to cancel the launch.
Details and reasons are not yet available. A new launch attempt, as reported by SpaceX, will no longer be made today.

The rocket was to launch a new–generation GPS III-4 geolocation satellite into orbit. It should enter the constellation of GPS geolocation satellites. There are already three new-generation GPS III devices that meet the needs of the US armed forces and civilian users.
