ROSETTA-ORBITER 67P RSI: Radio Science Gravity Measurements for Comet 67P

2016-01-20T07:58:25.000 to 2016-01-20T13:51:46.000, this dataset contains Radio Science data collected by the Rosetta spacecraft during its EXTENSION 1 phase at comet 67P/Churyumov–Gerasimenko. It is a Global Gravity measurement, covering a specific observation window. The data was published by the National Aeronautics and Space Administration (NASA) and last updated on the datagov platform in March 2026.

Use Cases

• Modeling the internal mass distribution and gravity field of comet 67P based on the described gravity measurements.
• Analyzing spacecraft trajectory and orbital dynamics during the Rosetta mission's EXTENSION 1 phase.
• Studying comet composition and density through derived gravity data.
• Calibrating or validating radio science instrumentation and data processing methods for deep space missions.

Strengths

• Data originates from the authoritative Rosetta space mission operated by ESA with NASA involvement.
• Covers a precisely defined observation window from 2016-01-20T07:58:25.000 to 2016-01-20T13:51:46.000.
• Focuses on a specific scientific measurement type: Global Gravity at comet 67P.

Limitations

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