ROSETTA-ORBITER 67P SREM 2: Radiation Count Rates at Comet 67P

Standard Radiation Environment Monitor (SREM) count rates and standard deviations from the Rosetta spacecraft during its EXTENSION 2 mission phase. The data, classified as CODMAC Level 2 Experiment Data Records, measure the radiation environment around the primary target, comet 67P/Churyumov-Gerasimenko, for the Medium Term Plan 29 period. NASA published this dataset, which was last updated on March 13, 2026.

Use Cases

• Modeling spacecraft radiation exposure based on measured count rates.
• Analyzing temporal radiation variations during the EXTENSION 2 mission phase.
• Correlating environmental radiation with comet activity for comet 67P/Churyumov-Gerasimenko.
• Validating space weather models using in-situ SREM instrument measurements.

Strengths

• Data is classified as CODMAC Level 2 Experiment Data Records, indicating a defined level of processing.
• Includes standard deviations alongside count rates, providing error estimates.
• Originates from a well-documented NASA mission, the Rosetta orbiter.
• Last updated on 2026-03-13, suggesting recent metadata maintenance.

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.
