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

Comet 67P/Churyumov–Gerasimenko gravity data collected by the Rosetta spacecraft's Radio Science Investigation (RSI) instrument. The dataset contains measurements from the ROSETTA EXTENSION 1 mission phase, covering a specific observation period on 2016-02-02. It was published by the National Aeronautics and Space Administration (NASA) and last updated on the datagov platform in April 2026.

Use Cases

• Modeling the gravitational field of comet 67P based on the described radio science measurements.
• Analyzing temporal changes in comet mass or density during the 2016 observation window.
• Validating orbital dynamics and spacecraft navigation models for the Rosetta mission.
• Studying the internal structure and homogeneity of a comet nucleus using gravity data.

Strengths

• Data originates from a definitive space mission, the Rosetta orbiter, providing authoritative measurements.
• Covers a specific and documented time range from 2016-02-02T22:34:05.000 to 2016-02-02T23:45:07.500.
• Focuses on a globally significant celestial body, comet 67P/Churyumov–Gerasimenko.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical needs.
• The description metadata is limited; actual data quality and completeness require manual inspection.
