SpaceX, ULA plan rocket launches for Wednesday

Last Updated: Tuesday, November 14, 2017, 6:27 PM EST

SpaceX plans to launch a Falcon 9 rocket from the Space Coast on Wednesday night.

  • SpaceX launch scheduled for Wednesday night from KSC
  • The Falcon 9 payload is the secretive Zuma project
  • Vandenberg AFB in California also to see launch Wednesday

The rocket will launch, which will blast off from Launch Pad 39A at Kennedy Space Center.

The launch window will open at 8 p.m. and last until 10 p.m.

The company will attempt to land the first stage of the rocket on land 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.

Sonic booms are likely when the rocket stage lands on land, as opposed to out on the droneship in the ocean. 

SpaceX has landed a first stage rocket booster at Landing Zone 1 seven times prior to this mission. The site on Cape Canaveral Air Force Station was a U.S. Air Force rocket and missile testing range.

The rocket will be carrying the Zuma, a satellite. But SpaceX is keeping mum on what the Zuma's purpose is.

Meanwhile, a United Launch Alliance rocket scheduled to lift off early Tuesday morning from Vandenberg Air Force Base in California was scrubbed because of technical issues.

The Delta II rocket is carrying the Joint Polar Satellite System, which will be used for severe weather prediction and environmental monitoring. That launch has been rescheduled for Wednesday at about 4:47 a.m. ET.

Also on Tuesday, a supply ship that lifted off from NASA's Wallops facility in Virginia two days ago delivered pizza and ice cream to the International Space Station. Italian astronaut Paolo Nespoli used the space station's robot arm to grab the cargo ship, as they zoomed 260 miles above the Indian Ocean. The capsule contained almost 4 tons of cargo, including high school students' experiments.
