A high-throughput communications satellite developed as a joint venture between Telesat and APT Satellite lifted off on top of a SpaceX Falcon 9 rocket at 12:45 a.m. EDT (0445 GMT) Monday from Cape Canaveral, following a delay to wait for storms to clear the Florida spaceport.
The engine test, called a static fire, saw the company ignite all seven of its BE-4 engines for less than half a minute. Local maritime and aviation hazards suggest a launch could happen as soon as Sunday, April 19.
