ROSETTA-ORBITER 67P: Radio Science Gravity Measurements During Extension 1

NASA's Rosetta Radio Science data set contains global gravity measurements for comet 67P/Churyumov–Gerasimenko. The data was collected during the ROSETTA EXTENSION 1 mission phase from 2016-01-01 to 2016-04-05, with a specific measurement interval on 2016-02-06. This dataset is version 1.0 and was last updated in the catalog on 2026-03 13.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity field measurements.
• Analyzing temporal variations in the comet's gravity field during a close orbital phase.
• Calibrating radio science instrumentation for future deep-space missions.
• Studying non-gravitational forces acting on the comet nucleus.

Strengths

• Data originates from a definitive NASA planetary science mission.
• Covers a specific, documented time range from 2016-01-01 to 2016-04-05.
• Focuses on a globally significant measurement type: gravity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The license is listed as 'other-license-specified', requiring review for usage terms.
