ROSETTA-MIDAS: Cometary Dust Particle Images and Catalogue

ROSETTA-MIDAS 5 PRL-TO-EXT3 V2.0 is a dataset from the Micro-Imaging Dust Analysis System instrument on the ROSETTA Orbiter. It includes 3D images and statistical parameters of pristine dust particles collected near comet 67P/Churyumov-Gerasimenko during the PRELANDING to EXTENDED 3 mission phases. The dataset is provided by NASA and supersedes a previous version after corrections.

Use Cases

• Analyze particle morphology based on 3D images of cometary dust.
• Calculate statistical parameters of dust populations based on the particle catalogue.
• Study the evolution of dust collection over mission phases from PRELANDING to EXTENDED 3.
• Validate instrument performance and data corrections based on the superseded version.

Strengths

• Dataset supersedes V1.0 after fixing target numbers, indicating quality improvements.
• Includes a dedicated particle catalogue implemented as a CSV table.
• Provides 3D images of pristine particles collected directly from a comet.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
