July 23 (UPI) -- SpaceX launched two Falcon 9 rockets with satellite payloads after they were scrubbed less than a minute before liftoff one day earlier in Florida and California.

In both situations, the rockets and payloads were in good health.

On Wednesday, the private agency launched two Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, or TRACER, for NASA at 2:13 p.m. PDT from Vandenberg Space Force Base in California. The mission was scrubbed just 45 seconds before liftoff Tuesday because of Federal Aviation Administration "airspace concerns" in the Santa Barbara area, which is midway between San Francisco and Los Angeles.

On Tuesday, SpaceX launched two O3b mPOWER satellites for Luxembourg-based SES from Cape Canaveral Space Station's Pad 40 in Florida at 5:12 p.m. EDT after the mission was scrubbed 11 seconds before liftoff.
