Luna-24 was the last spacecraft to land on the Moon (Soviet or American), on August 18, 1976. Boring 2.25 meters into the Moon, it obtained a 170.1 gram core sample 1.6 meters in length. The drilling apparatus packed the sample into a 8mm diameter plastic tube, which was wound into a helical container. At the Vernadsky Institute, the core was initially transfered to a flat spiral container to be x-rayed, then transfered to a series of trays.
