The two-hour launch window opens at 6:53 p.m. - four minutes before sundown - with a backup launch set for Thursday at 6:53 p.m. The satellite is called EchoStar 105 and SES-11 because of its deal mission, and it's created to offer both C-Band and Ku-band broadcast capabilities for EchoStar and communications for SES.
Stringent orbital requirements necessitated that liftoff of the SpaceX Falcon 9 booster rocket had to take place within a one-second launch window.
The Falcon 9 booster to be launched on Wednesday made its maiden voyage on February, 2017, on a mission to resupply the ISS.
The Falcon 9 will carry a high-powered communications satellite, which will work double-duty for the USA -based operator EchoStar and Luxembourg-based SES.
If the Falcon 9 launches at the beginning of the window, it should be a lovely display on the Space Coast.
The fourth Iridium Next launch is scheduled for November. The landing was a success for SpaceX's ongoing effort to re-use expensive rocket parts instead of jettisoning them into the ocean after launch.
EchoStar 105/SES-11 provides EchoStar with 24 Ku-band transponders of 36 MHz, marketed as EchoStar 105, while it provides SES with a C-band payload of 24 transponders, marketed under the name SES-11. On Wednesday, the organization is booked to launch a hybrid broadcasting satellite to be utilized by the two SES and EchoStar.
The launch will be broadcast live online and visitors to the Kennedy Space Center at Cape Canaveral are welcome to watch the launch.
SpaceX first re-flew one of these landed boosters on March 30, during the successful launch of the SES-10 communications satellite. There's a reinforcement launch date available on Tuesday at 8:31 AM ET.
