ROSETTA-ORBITER 67P RSI: Comet Gravity Measurements from 2016

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 from 2016-02-05T09:01:00.000 to 2016-02-05T12:40:08.500. It was last updated on the platform in March 2026.

Use Cases

• Modeling comet 67P's internal mass distribution based on gravity measurements.
• Analyzing spacecraft trajectory and orbital dynamics around a comet.
• Studying temporal variations in a comet's gravitational field during a close approach.
• Calibrating radio science instrumentation and methods for deep space missions.

Strengths

• Data originates from a definitive NASA mission, the Rosetta orbiter.
• Covers a specific and documented time range from 2016-02-05T09:01:00.000 to 2016-02-05T12:40:08.500.
• Focuses on a unique scientific measurement: global gravity for a 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.
• Description metadata is limited; actual data quality requires manual inspection after download.
