amples were studied and stored at the Vernadsky Institute of Geochemistry and Analytical Chemistry, GEOKhI, of the Russian Academy of Sciences. Some samples from the Luna-24 mission were provided to the Geological institute of the Czech Academy of Sciences, as well as 0.91 grams to the British scientists. During his visit to Moscow three months after Luna-24's return to Earth, NASA scientist Dr. Michael Duke exchanged three grams of samples from Luna-24 for 0.5 grams of samples delivered by Apollo astronauts. Luna-24 samples were then studied in the lunar research institute in Houston as well as a number of US academic institutions.

Does anyone know what institution(s) is (are) responsible for the storage and curation of the material returned by the three successful Luna sample return spacecraft that remains in Russian hands?
