Deep Space Fleet is provided free of charge for educational, research, and non-commercial scientific inquiry. The service is hosted by RogerLe.com as part of The Astronomy Academy federation.
You are free to reference, cite, and utilize the data models, calculations, and visualizations in academic papers, lectures, school projects, and astronomy outreach.
Orbital ephemerides and mission parameters are derived from public domain research and open scientific portals maintained by NASA JPL, ESA, JAXA, and partner institutions.
When utilizing aggregate datasets or visualizations from this site, proper attribution to both the originating agency (e.g. NASA/JPL Horizons, ESA Planetary Science Archive) and Deep Space Fleet / The Astronomy Academy is appreciated.
While every effort is made to maintain high fidelity against official ephemerides, telemetry positions, light-time delays, and heliocentric speeds are modeled using standardized orbital integration baselines.
This service is not intended for spacecraft navigation, flight operations, or safety-critical astronomical missions. All content is provided "as is" without warranty of any kind.
