The samples were opened on Tuesday as part of NASA's "Apollo Next-Generation Sample Analysis" (ANGSA) initiative.
These tests are intended to teach techniques to study future samples collected on Moon Artemis missions. NASA wants to land the first woman and next man on the moon by 2024.
Most of the samples returned from the Apollo missions were either studied or are part of ongoing research at NASA. However, some samples have been carefully preserved and reserved for testing with more advanced technologies.
"Today, we are able to make measurements that were simply not possible during the years of the Apollo program," said Dr. Sarah Noble, program scientist at ANGSA. "The analysis of these samples will maximize Apollo's scientific output and enable a new generation of scientists and curators to refine their techniques and prepare future explorers for lunar missions expected in the 2020s and beyond."
