The collection of lunar samples for lunar exploration dates back to the Apollo era, and the significant results of the Apollodeny moon program are reflected in collected lunar samples and a great deal of new findings from research institutes around these samples for half a century all over the world. The total of 6 Apollo lunar exploration events recovered 381.7Kg lunar samples with about 24Kg of samples with particles smaller than 1cm, most of these samples were subjected to preliminary size sorting in the Johnson space center with 1.3Kg of above 1cm fraction only. In addition, the Luna lunar exploration mission of the former soviet union returned a 301g sample of the moon.
