NASA is ready to open a 50-year-old moon rock. Are you?

By the end of the six Apollo missions that took place from 1969-72, astronauts brought back a total of 842 pounds of rocks and dust from the moon. Of the 2,200 samples, NASA scientists started studying all but two samples, which were left untouched and unopened. Now, after more than five decades of preservation, they’ve opened them!
