Diving into untouched lunar treasures

March 27, 2019 -  
Nearly 50 years ago, some very special materials were transported from outer space to Earth — unopened lunar treasures rocketed back by Apollo moonwalkers between 1971 and 1972. Nine “special samples” were collected in containers during the Apollo 15, 16 and 17 missions that had indium knife-edge...
