MIDAS: 3D Images of Comet 67P Dust Particles

The Micro-Imaging Dust Analysis System (MIDAS) instrument on the ROSETTA Orbiter captured 3D images and statistical parameters of pristine cometary particles near comet 67P/Churyumov-Gerasimenko. This dataset includes all data from the PRELANDING mission phase. The data is provided by NASA and the current release supersedes version 1.0 based on reviews held in February 2016 and October 2017.

Use Cases

• Analyzing particle morphology based on 3D imaging data
• Statistical modeling of dust properties based on statistical parameters
• Comparative studies of cometary material based on data from comet 67P/Churyumov-Gerasimenko

Strengths

• Data is from a dedicated scientific instrument (MIDAS) on the ROSETTA Orbiter
• Focuses on pristine particles collected in the vicinity of a specific comet (67P/Churyumov-Gerasimenko)
• Dataset version is explicitly stated as superseding a previous release (V2.0 supersedes V1.0)

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
