Frozen astronomy census
The registry connects global astronomy spacecraft to missions, instruments, observing programs, preserved archives, specialist catalogs, and documented outcomes without turning objectives into discoveries.

The global boundary is every spacecraft carrying GCAT’s astronomy classification, including failures and objects without a current AstronautAtlas mission page.
MAST, HEASARC, IRSA, Chandra, ESA, and Gaia retain native proposal, observation, product, and catalog identifiers.
SIMBAD, NED, and ADS remain specialist authorities. AstronautAtlas links to their identities instead of pretending to mirror every changing object or publication record.
Review the space-object census, the planetary archive, or return to methodology.
The shared science directory now exposes all 280 frozen astronomy observatories, 4,072 canonical instruments and payloads, 86 observing programs, and 330 results alongside their archive, target, operation, and sample relationships. Existing hardware and instrument pages are reused rather than duplicated.
