After a scrubbed first attempt SpaceX targets Thursday night for Falcon Heavy launch

Update: (Thursday, July 27) SpaceX has delayed the Falcon Heavy launch of the Jupiter 3 EchoStar satellite from Kennedy Space Center until Friday, July 28, at 11:04 p.m. EDT.

Update: (Thursday, July 27) Weather permitting, SpaceX teams in Florida are on track to attempt back-to-back launches from the Space Coast late Thursday. A Falcon 9 rocket with another batch of Starlink internet-beaming satellites from Cape Canaveral Space Force Station and a Falcon Heavy rocket with a communications satellite from Kennedy Space Center are set to liftoff less than an hour apart.Look for FLORIDA TODAY's live launch coverage to begin 90 minutes before the liftoff at https://www.floridatoday.com/space/.

Update: SpaceX scrubbed the first launch attempt of this mission on Wednesday, July 26, seconds before liftoff due to an unknown technical issue. The next launch attempt is Thursday, July 27, between 11:00 p.m. EDT and 12:43 a.m. EDT.

It's SpaceX Falcon Heavy launch (and landing) day!

After a scrubbed first launch attempt on Wednesday, July 26, teams at Kennedy Space Center in Florida are on track to launch a triple-core Falcon Heavy rocket overnight Thursday, July 27, sending the JUPITER 3 satellite built by Maxar Technologies for Hughes Network Systems to geostationary orbit. Follow FLORIDA TODAY's Space Team live launch coverage beginning 90 minutes before liftoff.

Here's everything you need to know:

  • The launch window extends from 11:04 p.m. EDT on Thursday, July 27, to 12:43 a.m. EDT Friday, July 28.

  • Launch Complex 39A at Kennedy Space Center will host.

  • Forecasters with the U.S. Space Force predict a 40% chance of "go" conditions throughout the launch window.

  • The payload is the JUPITER 3 satellite for Hughes Network Systems. It's the largest satellite ever built by Maxar Technologies. With the solar arrays fully deployed, it approaches the size of the wingspan of a commercial airliner and weighs roughly nine tons. It will join a fleet of EchoStar satellites in geostationary orbit to enhance the delivery of HughesNet internet connectivity to customers across North and South America.

Where to watch: SpaceX Falcon Heavy rocket launch; who will likely hear sonic booms

Rocket launch schedule: Upcoming Florida launches and landings

  • The 230-foot, triple-core Falcon Heavy rocket will follow a trajectory to the east-northeast away from Kennedy Space Center over the Atlantic Ocean.

  • After stage separation, the twin side boosters will somersault for a double landing attempt at Cape Canaveral Space Force Station's Landing Zones 1 and 2.

  • As the boosters return back to the Space Coast for landings, near simultaneous double sonic booms are expected to be heard throughout the Space Coast and surrounding areas depending on cloud cover and wind direction.

  • Extra performance is required for this mission which makes the center core booster expendable. SpaceX will not attempt to recover it.
