VO2 MARS RSS: Line-of-Sight Gravity from Viking Orbiter 2

79 orbits of Viking Orbiter 2 were tracked to produce line-of-sight gravity data for Mars. The data includes spacecraft latitude, longitude, accelerations, and altitude, with accelerations derived from raw Doppler residuals. This dataset was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling Martian crustal thickness based on gravity anomalies.
• Analyzing subsurface mass distribution based on line-of-sight acceleration data.
• Correlating topographic features with gravity signatures based on latitude, longitude, and altitude data.

Strengths

• Data derived from 79 distinct orbits of the Viking Orbiter 2 spacecraft.
• Acceleration data is provided with a specific conversion factor (100x) to milligals.

Limitations

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