Thursday's launch was scrubbed minutes before the 6:47 p.m. launch window due to an issue loading the liquid oxygen fuel. The next launch attempt date has not been released. 

Wednesday's countdown was halted about a half-hour before the launch window opened at 6:46 p.m. out of "an abundance of caution."

The SES-9 satellite is the heaviest yet that a Falcon 9 has attempted to lift on its way to an orbit more than 22,000 miles over the equator.

Atop the Falcon 9 is the SES-9 communications satellite owned by Luxembourg-based SES, one of the world's largest satellite operators with more than 50 in orbit.
