331 SEM images of microbial-induced corrosion (MIC) collected by Robert McLean from the NASA SpaceX-21 mission. The dataset includes both flight and ground control conditions with corresponding segmentation annotations for corrosion detection. It was last updated in February 2026 to support maintenance planning and corrosion mitigation research.
Use Cases
- Training semantic segmentation models to identify MIC regions in SEM imagery
- Comparative analysis of corrosion patterns between flight and ground control samples
- Developing automated maintenance planning tools for space-based infrastructure using MIC detection features
Strengths
- 331 SEM images with segmentation annotations
- Includes both flight and ground control conditions
- NASA SpaceX-21 mission source data
Limitations
- Small sample size of 331 images
- Specific to conditions of a single space mission
- Potential class imbalance between flight and ground control samples
