ROSETTA-ORBITER 67P SREM: Radiation Count Rates Near Comet 67P

Radiation count rates and standard deviations measured by the Standard Radiation Environment Monitor (SREM) aboard the Rosetta spacecraft. The data, classified as CODMAC Level 2 Experiment Data Records, characterize the radiation environment during the Medium Term Plan 31 period of the EXTENSION 3 mission phase. NASA produced this dataset, which was last updated on March 13, 2026.

Use Cases

• Modeling the radiation environment around comet 67P/Churyumov-Gerasimenko based on measured count rates.
• Analyzing temporal variations in spacecraft radiation exposure during the Medium Term Plan 31 mission phase.
• Validating radiation shielding models for deep-space missions based on empirical SREM measurements.
• Correlating radiation flux with spacecraft position and comet activity using the provided time-series data.

Strengths

• Data is classified as CODMAC Level 2, indicating processed and validated experiment data records.
• Includes standard deviations for the count rates, providing a measure of data uncertainty.
• Produced 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 for large-scale analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
