ROSETTA-ORBITER: Comet 67P Gravity Measurements from 2016

Rosetta spacecraft gravity data captured during a 3-hour, 49-minute window on 2016-01-31. This dataset from NASA's ROSETTA EXTENSION 1 phase provides global gravity measurements for comet 67P/Churyumov–Gerasimenko. It was last updated on the datagov platform in March 2026.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity measurements.
• Analyzing temporal gravity variations during the spacecraft's close approach in 2016.
• Calibrating radio science instrumentation for future deep-space missions.
• Studying comet nucleus properties like density and porosity from global gravity data.

Strengths

• Data originates from NASA's authoritative Rosetta mission.
• Covers a specific 3-hour, 49-minute observation window with precise start and end times.
• Focuses on a single, well-documented celestial body (comet 67P).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file format are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
