ROSETTA-ORBITER MIDAS: 3D Images of Cometary Dust from Earth Swing-By 1

Data from the Earth Swing-By 1 phase of the Rosetta mission, collected by the Micro-Imaging Dust Analysis System (MIDAS) instrument. The dataset provides 3D images and statistical parameters of pristine cometary particles. It was produced by the National Aeronautics and Space Administration and last updated on 2026-03-13.

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 based on the described statistical parameters.
• Study pristine cometary material from the early solar system based on the description of the particles as pristine.
• Validate and calibrate dust impact models for cometary environments based on the instrument's detection method.

Strengths

• Data originates from a dedicated scientific instrument (MIDAS) on the Rosetta Orbiter.
• Provides 3D imaging data, which is less common than 2D for particle analysis.
• Focuses on pristine cometary particles, offering a direct sample of early solar system material.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
