Rocket launch alerts — never miss a liftoff again
Rockets launch almost every other day now — over 200 orbital launches a year — and the best ones happen while you're not looking. Cosmik sends you a free push or email before every liftoff, with the live countdown and webcast one tap away. Set up your alert →

Every launch, not just the famous ones
Alerts cover every orbital attempt worldwide — SpaceX Falcon 9 and Starship from Starbase, NASA missions, Rocket Lab, ULA, Arianespace and the rest — powered by the same Launch Library data trusted across the space community. Browse the full rocket launch schedule or read our launch news and previews.
Then watch what the rocket left behind
Minutes after deployment, the payloads show up on Cosmik's live satellite tracker — follow a fresh Starlink train across your evening sky, or get a pass alert when the new satellite first crosses your city.
FAQ
How do I get notified before a rocket launch?
Open Cosmik, tap the launch countdown, and enable alerts — you'll get a free push notification or email before liftoff, with the live webcast link. It takes about ten seconds and works on any phone or desktop browser, no app required.
Are rocket launch alerts free?
Yes, completely free — browser push or email, your choice, with no account needed. Cosmik also updates you when a launch slips or scrubs, so you don't wait up for a rocket that isn't flying.
