ROSETTA-ORBITER 67P: Comet Gravity Measurements from Prelanding Phase

A Rosetta Radio Science dataset collected during the PRELANDING phase from 2014-01-21 to 2014-11 18. It contains global gravity measurements at comet 67P/Churyumov–Gerasimenko, specifically covering the period 2014-08-28T18:21:15.000 to 2014-08-29T00:44:10.500. 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 the global gravity measurements.
• Analyzing temporal variations in the comet's gravity field during the specified observation window.
• Calibrating and validating radio science instrumentation and methods for deep-space missions.
• Studying the relationship between a comet's gravity field and its surface features or activity.

Strengths

• Data originates from the authoritative NASA Rosetta mission.
• Covers a specific, well-documented observation period of over 6 hours.
• Part of a larger prelanding phase dataset spanning nearly 10 months.

Limitations

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