Two rocket launches scheduled to blast off from each coast Wednesday were both scrubbed, though Space Coast fans will get another chance to see a launch Thursday.

In California, United Launch Alliance is trying to launch a Delta II rocket with a weather and environmental monitoring satellite system from Vandenberg Air Force Base. A first launch attempt on Tuesday was scrubbed because of technical issues, and early Wednesday, high upper-level winds scrubbed the second attempt.

ULA and the National Oceanic and Atmospheric Administration have not announced a third launch time for the mission to deliver the NOAA's Joint Polar Satellite System-1.

Meanwhile, on the Space Coast, SpaceX pushed back the planned launch of a Falcon 9 rocket from Wednesday night to Thursday night to allow for more prep time, the company said.

"Both Falcon 9 and the payload remain healthy; teams will use the extra day to conduct some additional mission assurance work in advance of launch," SpaceX spokesman John Taylor said in an email.

The new launch window will open at 8 p.m. Thursday and will last two hours. The rocket, which will take off from Launch Pad 39A at Kennedy Space Center, will carry the Zuma, a satellite. SpaceX has kept mum on what the Zuma's purpose is.

SpaceX will try to land the first-stage booster at Cape Canaveral Air Force Station. SpaceX issued a sonic boom alert for the landing, saying residents in Brevard, Orange, Osceola, Seminole and Volusia counties may hear one or more sonic booms during the landing attempt.
