After scrubbing Wednesday night's launch so it can have enough preparation time, SpaceX decided to push Thursday night's attempt to launch a Falcon 9 rocket back as well.

SpaceX pushed back its planned Wednesday evening launch to allow for more prep time, the company said.

On Thursday night, SpaceX released a statement, saying the company was taking "a closer look at data from recent fairing testing for another customer.

"Though we have preserved the range opportunity for tomorrow, we will take the time we need to complete the data review and will then confirm a new launch date,” said spokesman John Taylor.

Which means there's a chance the rocket may not launch Friday, but as of right now SpaceX is operating as if it will happen.

If it happens, the launch window will open at 8 p.m. Friday 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, alerting those in Brevard, Orange, Osceola, Seminole and Volusia counties that they might hear one or more sonic booms during the landing attempt.

Meanwhile 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.
