Underground Astronauts

The Underground Astronauts is the name given to a group of six scientists who excavated the bones of "Homo naledi" from the Dinaledi Chamber in South Africa. Hannah Morris, Marina Elliott, Becca Peixotto, Alia Gurtov, K. Lindsay (then Eaves) Hunter, and Elen Feuerriegel were selected by expedition leader Lee Rogers Berger.
In November 2013, the National Geographic Society and the University of the Witwatersrand funded an expedition called Rising Star Expedition for a twenty-one day excavation at the cave, followed by a second expedition in March 2014 for a 4-week excavation in the Dinaledi Chamber. In total, the expedition retrieved 1,550 pieces of bone belonging to at least fifteen individuals, found within 1 m2 of clay-rich sediments. They entered a narrow opening in the cave to reach the chamber where the bones were located, and as the expedition was dangerous, they were named the "Underground Astronauts".
