(FloridaToday.com) - SpaceX hopes to make a third attempt to launch commercial satellites from Cape Canaveral on Tuesday, after putting off a planned try Sunday.
The company said engineers found a "potential concern" during pre-flight checks Sunday and would take more time "to ensure the highest possible level of mission assurance prior to flight."
A launch attempt on Sunday would have been the third in three days. Technical problems with the Falcon 9 rocket scrubbed a countdown Friday, and stormy weather scrubbed one Saturday.
Before those attempts, plans called for the Air Force to close the Eastern Range this week for scheduled maintenance, work that had been put off to fit in additional launch opportunities for SpaceX.
The Air Force has not confirmed the maintenance schedule or the range's availability this week.
SpaceX on Sunday said it would keep its 224-foot Falcon 9 rocket vertical at Launch Complex 40 in preparation for a next available launch opportunity targeted for Tuesday.
The Falcon 9 is carrying the first six of 17 second-generation satellites for Obcomm Inc., a provider of machine-to-machine communications.
