ROSETTA-ORBITER 67P: Radio Science Gravity Measurements at Comet 67P

Rosetta spacecraft radio science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. This dataset provides a global gravity measurement at comet 67P, specifically covering the time period 2014-10-27T04:56:57.000 to 2014-10-27T14:34:12.000. The data originates from the National Aeronautics and Space Administration and was last updated on the 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 prelanding observation window.
• Calibrating or validating orbital dynamics models for the Rosetta spacecraft.
• Comparing gravity field data with other Rosetta instrument datasets for a multi-parameter analysis of the comet.

Strengths

• Data originates from the authoritative Rosetta mission operated by the National Aeronautics and Space Administration.
• Covers a specific, high-resolution 9.6-hour observation window on 2014-10-27 for focused analysis.
• Part of the defined PRELANDING operational phase spanning nearly ten months from January to November 2014.

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.
