Celestrak vs Science
In-depth architectural comparison of the Celestrak and Science MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Celestrak
Aerospace & Astrodynamics · Remote HTTP/SSE
Quality: 51/100 (Good) | Auth: No auth required
Science
Aerospace & Astrodynamics · Remote HTTP/SSE
Quality: 56/100 (Good) | Auth: No auth required
Verdict Summary: Choose Celestrak if you need specialized Aerospace & Astrodynamics tools running via a hosted cloud SSE transport. Choose Science if your workspace requires Aerospace & Astrodynamics integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Celestrak when:
You need dedicated capabilities in the Aerospace & Astrodynamics domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Get satellite orbital elements (TLE / GP data) for a single object by NORAD catalog ID. Returns orbital parameters: inclination, eccentricity, mean motion, RAAN, argument of perigee, epoch, and derived orbital period in minutes. norad_id 25544 = ISS, 20580 = Hubble. This is the orbital catalog, not…
search_by_name
Search the satellite catalog by name substring and return matching orbital elements (TLE / GP data). e.g. "STARLINK", "NOAA", "GPS". Returns up to 50 matches with orbital parameters (inclination, eccentricity, period). Catalog/orbital data, not live tracking.
get_group
List orbital elements (TLE / GP data) for an entire CelesTrak group — e.g. the Starlink, GPS, or weather satellite catalog. Groups: "stations", "starlink", "gps-ops", "weather", "science", "geo", "active". Returns up to 100 satellites with orbital parameters (inclination, eccentricity, period). Cat…
Science Tools (4)
get_iss_location
Fetch the International Space Station's current latitude, longitude, and Unix timestamp from the Open Notify API. No inputs required; returns a real-time position fix.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Celestrak is categorized under Aerospace & Astrodynamics and uses a remote streaming HTTP/SSE transport. In contrast, Science belongs to Aerospace & Astrodynamics using remote streaming HTTP/SSE transport. Select Celestrak when you need capabilities focused on aerospace & astrodynamics and Science when you require tools for aerospace & astrodynamics.
Retrieve up to 20 globally recent earthquakes from the USGS FDSN service, filtered by lookback period (1–30 days, default 1) and minimum magnitude (default 4.0). Returns magnitude, location name, depth (km), coordinates, time, and tsunami warning flag.
get_air_quality
Check current air quality at a latitude/longitude. Returns US AQI score and category plus PM2.5, PM10, ozone, NO2, and CO levels.
get_apod
Get NASA's Astronomy Picture of the Day with image URL, title, and explanation. Optionally specify a date (e.g., '2024-01-15').
