ROSETTA-ORBITER 67P: Radio Science Gravity Measurements During Prelanding Phase

Rosetta Radio Science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. It contains global gravity measurements for comet 67P/Churyumov–Gerasimenko, specifically covering the time period 2014-10-27T04:02:05.000 to 2014-10-27T14:34:12.000. The dataset is provided by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling comet 67P's gravitational field based on the global gravity measurement.
• Analyzing spacecraft radio signal propagation during the prelanding phase.
• Studying temporal variations in comet gravity during the specified 10-hour observation window.
• Calibrating or validating orbital dynamics models for the Rosetta mission.

Strengths

• Data originates from the authoritative Rosetta mission operated by ESA, with NASA as the listed provider.
• Covers a specific and defined 10-hour observation period on 2014-10-27.
• Focuses on a specialized global gravity measurement for a well-known comet.

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 of specific terms.
