Celestial Node
Connects Claude to Celestial Node's space data APIs with 18 read-only tools covering ISS and Tiangong tracking, crew rosters, rocket launches, Mars weather, and a million-star catalog from ESA Gaia. Works anonymously at 25 requests per hour or with a free API key for higher limits. Reach for this when you need real-time orbital positions, upcoming launch schedules, near-Earth asteroid data, or Mars surface conditions. All GET requests, aggregating from NASA, ESA, CNSA, JAXA, Roscosmos, and other agencies. The encyclopedia search covers spacecraft, missions, and engines if you need historical reference data alongside the live feeds.
