SpaceX is prepping for a Monday launch out of Cape Canaveral for a Falcon 9 rocket carrying a Thai communication satellite.
The launch was originally scheduled for last Friday, but no reason for the delay was given.
One source said engineers were studying an issue with the Falcon 9 launch vehicle.
SpaceX's last launch out of Cape Canaveral was delayed three times in November because of computer and mechanical issues.
Meanwhile, Monday's scheduled launch is just one of many for SpaceX's international customers.
In fact, more than half of the launches on the 2014 manifest for the California-based company consist of clients from around the world.
It's a sign, some say, that commercial space flight is on the rise in the U.S.
Dale Ketchum, Chief of Strategic Alliances for Space Florida, said, "The fact that we are starting to see that become a reality is encouraging for any American, as it should be, because these are jobs that are now being done in America."
Because of the increase in commercial space flight, Ketchum is pushing for the construction of a commercial-only launch complex just north of Kennedy Space Center.
Early renderings show a two-tower facility built on a 200-acre plot of land in the Shiloh area.
The Federal Aviation Authority is expected to hold public meetings about the proposed launch complex beginning in mid-February.
A launch window has been set between 5:06 p.m. to 7:06 p.m.
If Monday's launch is scrubbed, back-up launch opportunities are available starting January 8 through January 12.
