SpaceX scrubbed a rocket launch Sunday afternoon, postponing it until Monday.
Another attempt will be made Monday at 8:34 p.m.
The planned launch will be the first since a summer accident grounded the company's Falcon line of rockets.
The company conducted a test-firing of its rocket at Cape Canaveral Friday.
It took three days for SpaceX to complete the test.
Chief executive Elon Musk said the engine firing appeared to go well.
SpaceX's rockets have been grounded since one failed during liftoff in June. The accident occurred on a space station supply run for NASA.
The upcoming flight will involve a satellite delivery for OrbComm.
If it goes well, flights for NASA could resume in February.
The company will attempt, again, to land the spent first-stage booster.
Monday's weather conditions are projected to be 10 percent more favorable for the landing, Musk tweeted.
