About NASA Launches
What counts as a NASA-related launch
NASA does not operate every rocket that carries a NASA spacecraft. Modern NASA missions frequently fly on commercial launch vehicles, and some projects involve international partners. This page therefore looks for NASA-related references across the upstream launch record instead of assuming that the launch service provider must be NASA itself.
The result can include science observatories, planetary missions, Earth-observation spacecraft, technology demonstrations, crew flights, cargo missions and other launches in which NASA is identified in the available mission data. The rocket, provider and pad fields remain separate so visitors can see who is flying the mission and where it will launch.
Why NASA mission dates evolve
NASA missions typically pass through extensive spacecraft testing, launch-vehicle integration and readiness reviews. A planetary mission may also have a narrow launch period determined by orbital mechanics, while a station mission can depend on rendezvous geometry and traffic around the destination. Weather and range constraints still apply on top of those mission-specific factors.
The schedule is therefore dynamic. SpaceTracker.live refreshes its shared data every fifteen minutes when required and removes launch windows that are no longer upcoming. If the source database changes a target, the NASA page follows that change automatically rather than preserving an obsolete manually written date.
Images and mission context
Launch cards show the best available image tied to the live record. The page prefers the specific launch image and then falls back to pad, location or provider imagery. Credits are retained when supplied. This helps distinguish a mission flying on a Falcon rocket from one launching on another vehicle or from another spaceport.
The local-time conversion is especially useful for NASA missions watched by a global audience. A launch from Florida in the evening can occur after midnight for viewers in Europe or Asia. The browser uses the device timezone so the displayed date and time match the viewer rather than forcing manual UTC conversion.
From launch to deep-space or orbital tracking
Once a NASA mission leaves the pad, its next home on SpaceTracker.live depends on the trajectory. Earth-orbiting spacecraft can move into the satellite tools after cataloguing. Missions travelling toward the Moon, Lagrange points or other planetary destinations fit the Deep Space section. A rocket-launch page should not pretend to be a complete mission tracker after deployment.
Use the NASA page to answer the pre-launch questions—when, what rocket, which provider and which site—then switch to the appropriate live tracker when authoritative post-launch trajectory or orbital data becomes available.
Using the NASA page without confusing agency and provider
One of the most common sources of confusion in launch schedules is assuming that the organisation responsible for a spacecraft must also own the rocket. Commercial launch services make that assumption unreliable. Keeping NASA mission context separate from the provider field lets a visitor understand, for example, that a NASA payload may fly on a vehicle operated by another company while still being correctly included on the NASA-focused page.
This distinction also improves internal navigation. Before launch, the NASA page helps with time, rocket and site. After launch, mission-specific tracking may move elsewhere on SpaceTracker.live. That prevents one page from trying to be a launch calendar, orbital tracker, deep-space ephemeris and mission-history article all at once.
Data freshness and schedule transparency
The small schedule-state notice is also important near major NASA mission milestones. It indicates whether the page is using a fresh shared response, a newly refreshed response or a previous valid copy because the remote service could not be reached. That transparency is preferable to silently presenting old information as live. For a mission close to launch, combine the SpaceTracker.live schedule with the latest official mission update so a late hold, scrub or range change is not missed.
For satellite objects that have already reached orbit, use Recently Launched Satellites. For wider orbital tracking, open the Satellite Directory or the Deep Space section.
How NASA classes its science missions
| Class | Typical role | Examples |
|---|---|---|
| Discovery | Lower-cost focused planetary missions | Lucy, Psyche |
| New Frontiers | Medium-cost missions to answer major questions | New Horizons, Juno, OSIRIS-REx |
| Flagship | Large, high-cost, long-development missions | James Webb Space Telescope, Europa Clipper |
Because NASA buys launches from commercial providers, a NASA mission may appear in the schedule under a company rocket name rather than a NASA vehicle.
NASA launch milestones
| Date | Event |
|---|---|
| 20 Jul 1969 | Apollo 11 lands the first humans on the Moon |
| 12 Apr 1981 | First Space Shuttle flight (STS-1) |
| 21 Jul 2011 | Last Space Shuttle mission (STS-135) |
| 25 Dec 2021 | James Webb Space Telescope launches on Ariane 5 |
| 16 Nov 2022 | Artemis I launches on the Space Launch System |
| 14 Oct 2024 | Europa Clipper launches toward Jupiter on a Falcon Heavy |
Most dates above are launch dates; arrival, landing or first-science dates are separate events.

Data, update and accuracy details
- Data source: the Launch Library 2 database from The Space Devs, which aggregates launch-provider announcements.
- How often data refreshes: the schedule is cached on our server for up to 15 minutes; refresh the page to see the newest cached copy.
- Accuracy: launch times can change at short notice because of weather, range conflicts or technical checks. The page shows the planned time and its precision label; it is not a live telemetry or webcast feed. Confirm critical plans, such as travelling to a viewing site, with the launch provider.

Frequently asked questions
Does NASA launch every NASA mission itself?
No. NASA missions can fly on launch vehicles operated by commercial or international launch providers.
How are NASA-related launches selected?
The page looks for NASA or National Aeronautics and Space Administration references in the upstream launch record.
Why might a NASA mission not appear yet?
A mission may be too far in the future, not yet present in the current feed or represented without a NASA label in the available record.
Does NASA launch its own rockets?
Mostly not. NASA buys launches from companies such as SpaceX, United Launch Alliance and Rocket Lab. Its own Space Launch System (SLS) rocket is used for the Artemis Moon missions.
Where does NASA launch from?
Most NASA missions launch from Kennedy Space Center and Cape Canaveral in Florida. Polar-orbiting satellites launch from Vandenberg in California, and smaller missions from Wallops Flight Facility in Virginia.
When is the next NASA launch?
The countdown at the top of this page shows the next NASA-related launch with a confirmed time, in your time zone. Missions that only have a target month are listed below with that target.
