Rocket Launch Today USA
Follow upcoming orbital launches from United States spaceports with live countdowns.
How to use this tracker
Launch dates can move. Open a mission card for details and use the webcast button when an official or provider stream is available.
Launch schedules are operational plans, not fixed appointments. The live list above is designed to keep mission times dynamic and to show provider, site, mission and webcast information when the upstream source supplies it.
Why launch dates move
Spaceflight schedules can change for reasons that have nothing to do with a problem on the rocket. Weather, launch-range coordination, payload readiness, upper-stage work, recovery conditions and another mission using shared infrastructure can all alter a target time.
A mission marked NET—“not earlier than”—should be read literally. It identifies the earliest current target, not a guarantee of liftoff. A hold or scrub can move a launch by minutes, hours or days.
How to read mission cards
Start with the mission name and provider, then check the launch site and displayed local/UTC time. Open the mission detail where available for payload or target-orbit context. If a webcast link is listed, it should be treated as the best route to live coverage rather than searching for unofficial rebroadcasts.
If you are planning to watch in person, use the launch provider and range/spaceport information as the final authority for visitor access, road closures and viewing rules.
What this page includes—and what it does not
This page filters the upstream launch database to United States launch locations. It is useful for discovering missions and monitoring schedule changes, but it is not a launch-control system and does not independently certify that a vehicle is “go” for flight.
Status wording can lag an operator announcement if the upstream database has not yet synchronized. Refreshing the page close to launch time is therefore sensible.
Where the schedule comes from
The live tracker uses The Space Devs Launch Library 2 as its structured schedule source and then applies U.S. location filtering. For NASA-operated missions, you can also compare against the official NASA launch schedule.
Best practice before a launch
Check the card when you first plan, check again the day before, and check once more shortly before the window. If the mission has an official provider page or webcast, use that source for final countdown status. This avoids relying on a date copied into an older article or social post.
Frequently asked questions
What does NET mean?
NET means “not earlier than.” The mission may launch at that time or later if the target changes.
Why does a countdown suddenly increase?
The source schedule may have been updated after a delay, scrub or new launch-window decision.
Does this page include launches outside the United States?
This page focuses on U.S. launch locations. Use the global launch tracker for broader coverage.
Are webcast links guaranteed?
No. A link is shown only when the data source provides one, and providers can change coverage details.
How to read today's U.S. rocket launch schedule
A launch date is a schedule, not a guarantee. Mission cards can move because of weather, range conflicts, technical work, spacecraft readiness or changes elsewhere in the launch campaign. Use the countdown as a convenient representation of the currently published time, then recheck the source close to liftoff.
Launch window, launch time and NET
A mission may have an instantaneous launch time or a wider launch window. “NET” means “no earlier than” and indicates that a mission is not expected to launch before the stated time or date; it can still move later. When a provider publishes only a broad window or date, a responsible tracker should preserve that uncertainty rather than inventing an exact liftoff time.
Where U.S. orbital launches happen
Major U.S. launches can depart from spaceports in Florida, California and other licensed locations depending on the required orbit and mission. East-coast sites are commonly used for many low-inclination, geostationary and crewed missions, while west-coast sites are useful for polar and Sun-synchronous trajectories. The tracker filters the global source data to U.S. locations rather than maintaining a separate hand-written calendar.
Where the schedule data come from
The page uses Launch Library 2 from The Space Devs, a community-maintained public spaceflight database. Their project and API documentation are available at The Space Devs. Official launch providers remain the final authority for mission-specific changes.

Frequently asked questions
Why did a countdown suddenly increase?
The underlying launch time was likely delayed or rescheduled. A live schedule should reflect the newest published time rather than continuing an obsolete countdown.
Does every mission have a webcast?
No. The tracker should show a webcast only when the data source or launch provider supplies one.
