MAVEN Ephemeris: Daily Heliocentric Trajectory Coordinates

Heliocentric trajectory data for the MAVEN spacecraft in Heliographic, Heliographic Inertial, and Solar Ecliptic coordinates. The data is produced by NASA using the 'Mean of Date' method for the Equinox Epoch, with original trajectory data sourced from JPL Horizons. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling spacecraft orbital dynamics based on heliocentric coordinate data
• Analyzing solar wind interactions based on spacecraft position relative to the sun
• Calibrating space weather models based on precise heliographic coordinates
• Studying long-term orbital drift based on the 'Mean of Date' Equinox Epoch method

Strengths

• Data originates from authoritative sources: NASA and JPL Horizons
• Coordinates are calculated using the defined 'Mean of Date' method for the Equinox Epoch
• Dataset was last updated on March 13, 2026

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
