NASA Open Data Scraper

Search and extract metadata from NASA's Open Data Portal — powered by CKAN with 40,000+ NASA datasets covering Earth science, space exploration, aeronautics, climate, and more. No API key required.

What you can scrape

• Datasets — titles, descriptions, resources (files), tags, organization, license, metadata dates, resource counts
• Dataset detail — full metadata for specific datasets by ID or slug
• Organizations — NASA organizations publishing open data, with package counts

Use cases

• NASA research data discovery and analysis
• Finding Earth science, climate, or space datasets
• Academic and scientific research
• Building data pipelines from NASA open sources
• Tracking dataset availability by NASA program
• Discovering datasets in specific formats (CSV, GeoJSON, HDF, FITS, etc.)

FAQ

Do I need an API key? No. NASA's Open Data Portal CKAN API is fully open and does not require authentication.

How many datasets are available? Over 40,000 NASA datasets covering Earth science, space exploration, aeronautics, climate research, and more.

Can I filter by file format? Yes. Use the format field to filter by CSV, JSON, ZIP, PDF, GeoJSON, and more.

Can I search by NASA organization? Yes. Use the organization field with nasa as the slug.

What's the difference between searchDatasets and getDatasetDetail? searchDatasets performs keyword search and returns many results. getDatasetDetail fetches complete metadata for specific datasets by their ID or slug.

Why are some fields missing from output? Only fields with actual data are included. No null or blank values are emitted.

Can I get datasets sorted by date? Yes. Set sortBy to metadata_modified desc for recently updated datasets or metadata_created desc for newest additions.

What science topics are covered? NASA's portal includes data from Earth science, space physics, planetary science, astrophysics, aeronautics, human spaceflight, and climate research programs.
