Description
Data from 2002-05 29 to 2015-10-20 documents the operational history of the COSIMA instrument on the Rosetta orbiter. It contains records of 72 dust collecting substrates, with operations including expose, storage, spectra, and imaging. This dataset, produced by the National Aeronautics and Space Administration, supersedes all previous COSIMA data versions.
Use Cases
Analyze instrument health and operational functionality based on the history of substrate operations.
Study dust collection patterns near comet 67P/Churyumov-Gerasimenko based on the D0 substrate set exposures from 2014-08.
Investigate the impact of instrument failure and recovery on data quality based on the timeline of SIMS operations.
Compare dust analysis results from different substrate sets (e.g., CD, CF, D1) based on the TOF-SIMS measurements described.
Strengths
Covers a long operational timeline of over 13 years, from 2002 to 2015.
Tracks operations for 72 distinct dust collecting substrates.
Supersedes and corrects data from at least five previous dataset versions, including temperature unit errors.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
SIMS data is described as scientifically unusable for a period after 2014-10-23 due to an instrument failure.
Row count is unknown, which may limit suitability assessment.
