ROSETTA-ORBITER 67P RSI: Comet Gravity Measurements from 2016

NASA's Rosetta Radio Science data set provides global gravity measurements of comet 67P. The data was collected during the ROSETTA EXTENSION 1 phase from 2016-01-01 to 2016-04 05, with a specific measurement time from 2016-01-21T07:54:35.000 to 2016-01-21T13:47:37.500. The dataset 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 variations in gravitational pull during the Rosetta mission's extension phase.
• Calibrating spacecraft trajectory models using radio science data.
• Comparing gravitational data with other comet surface and composition datasets.

Strengths

• Data originates from the authoritative NASA Rosetta mission.
• Covers a specific and documented time range for gravity measurements.
• Focuses on a single comet (67P) for targeted analysis.

Limitations

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