ROSETTA-ORBITER: 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 for comet 67P, specifically covering a 6-hour window on 2014-08-26. The data originates from the National Aeronautics and Space Administration.

Use Cases

• Modeling the gravitational field and mass distribution of comet 67P based on radio science measurements.
• Analyzing spacecraft trajectory and orbital dynamics during the prelanding phase.
• Studying temporal variations in comet activity and their influence on gravity signals.
• Calibrating and validating radio science instrumentation for deep space missions.

Strengths

• Data collected by the Rosetta orbiter, a flagship European Space Agency mission.
• Covers a specific, critical prelanding operational phase from 2014-01-21 to 2014-11-18.
• Provides a focused gravity measurement from a precise 6-hour window on 2014-08-26.

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.
