ROSETTA-ORBITER 67P SREM 2: Radiation Count Rates During Prelanding Phase

NASA's Rosetta spacecraft measured radiation count rates and standard deviations in the environment around comet 67P/Churyumov-Gerasimenko. The data are CODMAC Level 2 Experiment Data Records from the Medium Term Plan 4 period of the PRELANDING mission phase. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling the radiation environment around comet 67P/Churyumov-Gerasimenko based on count rates.
• Assessing spacecraft instrument performance and health based on SREM measurements.
• Correlating radiation levels with spacecraft position and mission phase during the PRELANDING period.

Strengths

• Data includes standard deviations for the count rates, providing uncertainty estimates.
• Data is classified as CODMAC Level 2, indicating processed experiment data records.
• Dataset is provided by NASA, an authoritative source for space science data.

Limitations

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