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: Polaris Dawn. This will also be available on the X platform. Coverage will start about 3.5 hours prior to 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

Given that this is a launch from Kennedy Space Center with no booster return to the Cape, Max Brewer Bridge and the northern Tistusville parks on Washington Avenue (US1) are your best bets: Space View Park, Rotary Riverview Park and others.

Merritt Island National Wildlife Refuge and Cape Canaveral National Seashore will be closed for the evening, but if the launch pushes past 6AM EDT, those areas should be open.
