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

Rosetta Radio Science data collected by NASA during the PRELANDING phase from 2014-01-21 to 2014-11-18. The dataset contains global gravity measurements for comet 67P/Churyumov–Gerasimenko, specifically covering the period from 2014-09-08T17:36:15.000 to 2014-09-09T00:00:10.000.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity field data.
• Analyzing temporal variations in the comet's gravity during the prelanding observation window.
• Calibrating radio science instrumentation for future deep space missions.

Strengths

• Data originates from the Rosetta orbiter, a flagship European Space Agency mission with NASA involvement.
• Covers a specific, defined observation window of over 6 hours on 2014-09-08 and 2014-09-09.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
