ROSETTA-ORBITER MIDAS: Cometary Particle Images and Statistics from 67P

The Micro-Imaging Dust Analysis System (MIDAS) instrument on the ROSETTA Orbiter collected 3D images and statistical parameters of pristine cometary particles near comet 67P/Churyumov-Gerasimenko. This dataset includes all data from the ROSETTA EXTENSION 2 mission phase and supersedes version 2.0. The data was produced by the National Aeronautics and Space Administration and was last updated on the platform in March 2026.

Use Cases

• Analyze the 3D morphology of cometary dust particles based on the micro-imaging data.
• Calculate statistical parameters of particle size and shape distributions from the instrument's measurements.
• Model cometary dust environments based on particle collection data from the vicinity of comet 67P.
• Validate and compare dust analysis models using the pristine particle data collected during the mission extension.

Strengths

• Data is from a dedicated space mission instrument (MIDAS) designed for pristine particle analysis.
• The dataset represents a specific, superseding release (V3.0) for the EXTENSION 2 mission phase.
• Source organization is the authoritative National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality and formats require manual inspection after download.
