It will launch 60 Starlink satellites in orbit on Wednesday, the first step in the company's plan to build a global satellite internet network.
The SpaceX Falcon 9 rocket, launched from Space Launch Complex 40 (SLC40) at the Cape Canaveral Air Force Station in Florida, will carry the satellites.
The first launch window is from 10:30 pm ET on Wednesday until 12:00 am on Thursday. If this fails, a second launch window will open at 10:30 p.m. ET on Thursday and close at 12:00 a.m. ET on Friday.
The live broadcast of the mission will begin approximately 15 minutes before takeoff, and you can see it below.
Starlink satellites will be deployed approximately one hour and two minutes after takeoff, at an altitude of 440 km, after which they will use on-board propulsion to reach an operational altitude of 550 km.
After the separation of the stage, SpaceX will try again to land the first stage of Falcon 9 on a ship in the Atlantic Ocean.

SpaceX also shared some new details about Starlink satellites. They have a flat panel design with a single solar panel and multiple high-performance antennas, and weigh approximately 227 kg each.
They are equipped with Hall thrusters powered by krypton, a Startracker navigation system, and can automatically avoid collision with debris. Once they have done their best, 95% of the components will burn in the Earth's atmosphere, which, according to SpaceX, exceeds all current safety standards.
According to SpaceX, this mission pushes the limits of what Starlink satellites can do, and hopes to find problems along the way.
"Our learning here is key to developing an affordable and reliable broadband service in the future," The company said.
