About
Mission control for everyone
Launches are scheduled for no earlier than a date and time, NET for short. Then they slip, hold and scrub, sometimes in the final seconds. No Earlier Than keeps up with every change, and your calendar with it.
What it does
Every launch in your calendar: SpaceX, Blue Origin, NASA, Europe’s orbital launches and every crewed flight worldwide. Subscribe once, and launches appear by themselves, move when they slip and bring the webcast, the timeline and an alert before liftoff.
Live from liftoff: every launch has its own page with a countdown in your time zone. Near T−0 it runs on SpaceX’s own clock where SpaceX publishes one, holds included. Falcon 9, Falcon Heavy and Starship stand in 3D, painted as SpaceX’s photos show them. Flights on SpaceX’s vehicle tracker fly live on a globe, Dragon all the way to the station.
Where the numbers come from
- Launches: Launch Library 2 by The Space Devs.
- Mission details, timelines and live positions: SpaceX’s public mission pages and vehicle tracker.
- Orbits of stations and satellites: CelesTrak’s orbital elements, computed with the standard SGP4 model.
- Weather at the pad: the nearest airfield within 16 km, as its METAR reports it, through NOAA’s Aviation Weather Center.
Every number on the site comes from them, and anything estimated says so.
Free for everyone

Why it exists
I wanted every launch in my calendar, with the webcast one tap away and an alert before liftoff, and a live view that follows the flight all the way. I couldn’t find anything that did all of that, so I built it. Now it’s mission control. For everyone.
