Tools & capabilities
Space Feeds tools 3
list_feedsList the curated space & spaceflight feeds (id, title, category, source). Optionally filter by category (space) or keyword. Pass an id to read_feed.read_feedRead a curated space & spaceflight feed by its id (from list_feeds). Returns normalized items (title, link, published, summary). Optionally filter items by keyword.fetch_feedFetch and normalize any RSS / Atom / RDF feed by URL. CF-robust: fetches directly and falls back to a proxy if the source blocks the gateway. Use list_feeds first for curated sources.
Mast Nasa tools 4
cone_searchSearch MAST around (RA, Dec).mission_searchMission-scoped search with arbitrary criteria.caomGeneric CAOM (Common Archive Observation Model) query.lookup_nameResolve target name → coords.
