Replay: SpaceX to launch SXM-8 satellite for Sirius XM, ,
Update for 1:15 a.m. EDT: SpaceX has successfully launched the Sirius XM SXM-8 radio satellite. See video and our launch wrap up here.
A SpaceX Falcon 9 rocket will launch a new Sirius XM radio satellite early Sunday, June 6, and you can watch it live here. Liftoff is set for 12:26 a.m. EDT (0426 GMT).
The mission, called SXM-8, will launch the satellite into orbit from Space Launch Complex 40 of the Cape Canaveral Air Force Station. It is the second launch in less than a week for SpaceX.
SpaceX’s launch webcast above will begin about 15 minutes before liftoff.
SpaceX is targeting Sunday, June 6 for Falcon 9’s launch of the SXM-8 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The one-hour and 59-minute launch window opens at 12:26 a.m. EDT, 4:26 UTC, and a backup launch opportunity is available on Monday, June 7 with the same one-hour and 59-minute launch window.
Falcon 9’s first stage booster previously supported SpaceX’s Crew-1 and Crew-2 missions, which launched astronauts to the International Space Station. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean. A live webcast of this mission will begin about 15 minutes prior to liftoff.

Find out what the astronauts and cosmonauts aboard the International Space Station are up to by tuning in to the “ISS Live” broadcast. Hear conversations between the crew and mission controllers on Earth and watch them work inside the U.S. segment of the orbiting laboratory. When the crew is off duty, you can enjoy live views of Earth from Space. You can watch and listen in the window below, courtesy of NASA.
“Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During ‘loss of signal’ periods, viewers will see a blue screen.
“Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below.”
