Rocket Launch Countdown Screensaver
The Rocket Launch Countdown screensaver counts down live to the next scheduled orbital rocket launch worldwide, showing the mission, vehicle and launch site — key-less, live from The Space Devs' Launch Library. It's free, runs in your browser, and ESC exits.
How the Rocket Launch Countdown screensaver works
The saver fetches the next scheduled orbital launches worldwide, with no key required.
A large countdown ticks down to the soonest confirmed launch time.
The mission name, rocket and launch site are shown beneath the clock.
An optional list previews the next few launches queued up after it.
A worked example
You might see the clock counting down to a real Falcon 9 launch from Cape Canaveral, with the mission name overhead — the actual next confirmed launch, not a placeholder.
Settings & tips
