Cosmic Disclosure S04 E09 Inner Earth: Missions

Some areas of the inner earth are so strange that it is like being on another planet, within our own planet. Emery Smith describes the technology and functions he was tasked with during his missions to explore and take samples from many subterranean caverns. He reveals that an important part of the way missions are conducted builds compartmentalization so that even the crew undertaking these missions do not know the full scope of the operation.
