SpaceX is set to launch Falcon 9 and the SES-operated O3b mPower satellites this evening from Space Launch Complex 40 at Cape Canaveral. Liftoff is set for 05:12 PM ET, with a two hour window extending to 07:12 PM ET.

Official weather forecasts have given the mission a 50/50 chance for acceptable weather, with roughly a 25% chance of thunderstorms in the launch area during the launch window. Keep in mind that acceptable conditions consider more than just rain, it also includes thunderstorm activity in the launch area as well as the lightning potential in the immediate vicinity of the rocket.

Boeing’s 9th and 10th O3b mPOWER satellites—launched in partnership with SES—will bolster the company’s push to deliver global connectivity from space. Leveraging Boeing’s fully software-defined payload technology, these satellites can dynamically allocate power to match user demand.

Today will mark the sixth mission for Falcon 9 first stage booster B1096, and after completing its share of the mission, the booster will touch down offshore on ASDS ‘Just Read The Instructions.’

Online Viewing

SpaceCoastLaunchCalendar.com will have a livestream of the launch if you’re not able to watch the launch in person: Livestream

SpaceX will have a livestream of the launch on their website: O3B MPower Mission. This will also be available on the X platform. Coverage starts about fifteen minutes before liftoff.

Spaceflight Now will have coverage of the launch starting about one hour before liftoff on Youtube: link

For official updates regarding launch times, SpaceX.com is the best source of information. Starlink launch times change from time to time, and the company generally updates their website within minutes of the decision to change the launch time. This is very handy if none of the streaming options on YouTube have started their broadcasts.

Remember that there is a delay between a launch stream and the actual countdown clock. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.

Next Space Flight an app for iOS and Android phones, has a real-time countdown clock that is accurate to a second, give or take. The app is free. Search the App Store or Google Play. They are also on the web: nextspaceflight.com.

Launch Viewing: In Person

The best free options are available for spectators: Northern Titusville parks on Washington Avenue / US-1 are your best bets: Space View Park, Sands Park, Rotary Riverfront Park.
