Curation
The careful storing, cataloguing, protecting and sharing of meteorites and other samples so they stay useful for science.
Curation covers everything that happens to a specimen after it enters a collection. A curator records its identity and history, gives it a catalogue number, stores it so it does not deteriorate, tracks every piece cut from it, and decides which researchers receive samples. Good curation keeps a meteorite scientifically valuable for centuries.
The biggest danger is contamination and change. Earth's air and water rust metal, alter delicate minerals and add organic compounds. So the most important samples are handled in clean, dry nitrogen cabinets and with tools that leave little trace. NASA's Johnson Space Center curates the Apollo Moon rocks, about 382 kilograms of them, alongside Antarctic meteorites and samples returned by spacecraft. Japan's space agency does the same for grains brought back from the asteroid Ryugu. When the Winchcombe meteorite fell in England in 2021, the first pieces were collected within days and stored carefully at the Natural History Museum in London, which made them especially valuable for studying their water-bearing minerals.
Signs of good curation are clear labels, catalogue numbers, records of each split, and careful storage. Private collectors can practise it too, by keeping specimens dry, labelled and documented.
