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

The Rosetta spacecraft's Standard Radiation Environment Monitor (SREM) instrument measured radiation count rates and standard deviations in the environment of comet 67P/Churyumov-Gerasimenko. These CODMAC Level 2 Experiment Data Record data were collected during the Medium Term Plan 9 period of the PRELANDING mission phase. The dataset was provided by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling the radiation environment near comet 67P/Churyumov-Gerasimenko based on measured count rates.
• Calibrating or validating spacecraft radiation monitors using the provided standard deviations.
• Analyzing temporal radiation trends during the Rosetta mission's Prelanding phase.
• Correlating radiation measurements with other spacecraft or cometary activity data.

Strengths

• Data is classified as CODMAC Level 2, indicating processed experiment data records.
• Includes standard deviations for the measured count rates, providing error estimates.
• Provided by the authoritative source, the National Aeronautics and Space Administration.

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.
