Your Gateway to Space Exploration
Track space launches, monitor the ISS, and discover asteroids in real-time.
Upcoming missions and selected flights. Featured missions may remain visible after launch.
Falcon 9 Block 5 | O3b mPower 11-13
3 high-throughput communications satellites in Medium Earth Orbit (MEO) built by Boeing and operated by SES.
Vega-C | Sentinel-3C & FLEX
Sentinel-3C is the third satellite in the Sentinel-3 constellation, which provides high-accuracy optical, radar and altimetry data for marine and land services. The Fluorescence Explorer (FLEX) satellite is a part of ESA's Earth Explorer program. The satellite will map vegetation fluorescence to quantify photosynthetic activity.
Zhuque-2E Block 2 | Unknown Payload
Possibly launch of a batch of SpaceSail LEO communication satellites. Details TBD.
What We Track
Comprehensive coverage of space activities from trusted sources like NASA and The Space Devs.
Space Launches
Real-time tracking of upcoming launches from SpaceX, NASA, Blue Origin, ISRO, CNSA, Roscosmos, and more. Features live countdowns, mission details, launch locations, and direct links to livestreams.
ISS Live Tracking
Follow timestamped ISS positions on an interactive map, with altitude, speed and a sampled ground track. Delayed updates are marked, and the guide explains what the map can and cannot tell you.
Near-Earth Asteroids
NASA-powered data on asteroids passing close to Earth. Includes size estimates, velocity, closest approach distance, and potential hazard classification. Updated hourly from JPL NeoWs.
Rocket References
Five source-linked vehicle references explaining configurations, published specifications and their limitations. No unsupported launch totals or reliability rankings.
Make sense of what you track
A launch time is a target, a map position is not a visibility forecast, and a close asteroid approach is not an impact warning. Start with the guide for the tool you are using.
Trusted Data Sources
All information on Spaceflight Tracker comes from reputable scientific and institutional sources
The Space Devs API
Launch Library 2 — the most comprehensive open-source space launch database maintained by a dedicated community of space enthusiasts and professionals.
NASA JPL NeoWs
Near Earth Object Web Service from NASA's Jet Propulsion Laboratory provides data on asteroids and their trajectories near Earth.
Where the ISS at?
International Space Station positions supplied by Where the ISS at?. Availability depends on the provider and your connection.
