search - Capability: `satellites/gp_search` - Description: Search current GP element sets by object name (substring, case-insensitive, at least 3 characters) or by international designator: a launch (YYYY-NNN returns every tracked object from it) or one object (YYYY-NNNA). Returns up to limit element sets with OMM keywords, TLE lines where available and derived orbit size. Source: CelesTrak gp.php?NAME= or ?INTDES= (JSON, plus TLE). An empty element_sets list means CelesTrak tracks nothing matching. Data refreshes about every 2 hours (CelesTrak usage policy: download once per update); epoch_age_hours shows freshness. Objects cataloged since 2026-07-11 have 6-digit catalog numbers and no TLE, only OMM. - Instructions: Find a satellite, rocket body or crewed vehicle by name (STARSHIP, ZARYA, HUBBLE) or every object from one launch once it is cataloged, e.g. a new SpaceX launch by its designator. - Cost: 5 credits per call - Capability file: [Gp search](https://alexandria.firecrawl.dev/agents/providers/celestrak-org/satellites/gp_search) Accepted options: - `international_designator` (string): Launch designator YYYY-NNN (all objects from that launch) or object designator YYYY-NNNA. Pattern: ^\s*[0-9]{4}-[0-9]{3}[A-Za-z]{0,3}\s*$. Example: `` - `limit` (number): Most element sets to return (default 100). Example: `100` - `name` (string): Part of the object name, e.g. ZARYA or COSMOS 2251 DEB. Exactly one of name or international_designator.
