Cross-section of the Rising Star Cave system

The Underground Astronauts is the name given to a group of six scientists:[1] Hannah Morris, Marina Elliott, Becca Peixotto, Alia Gurtov, K. Lindsay (then Eaves) Hunter,[2] and Elen Feuerriegel, who excavated the bones of Homo naledi from the Dinaledi Chamber of the Rising Star cave system in Gauteng, South Africa.[3][4][5][6] The six women were selected by the expedition leader, Lee Rogers Berger,[7][8] who posted a message on Facebook asking for scientists with experience in paleontological excavations, caving, and were thin.[6] Within ten days of the post, Berger had received sixty applicants and chose six scientists to make up his expedition team.[9]

In November 2013, the National Geographic Society and the University of the Witwatersrand funded an expedition called the Rising Star Expedition for a twenty-one day excavation at the cave,[10] followed by a second expedition in March 2014 for a 4-week excavation in the Dinaledi Chamber. The first expedition retrieved 1,550 pieces of bone belonging to at least fifteen individuals, found within 1 m2 of clay-rich sediments.[11][5] Out of the fossil assemblage found, only twenty bones in the human anatomy were not found in the assortment.[5]

The six scientist had to pass through three points of difficult terrain in the cave to reach the bone chamber. One is referred to as 'Superman's Crawl', which required one arm held forward to pass, like in Superman's flight. Next, the scientists had to climb vertically up a rock surface, known as the 'Dragon's back', and then finally pass through an opening that was only 18 cm wide,[5][12] descending thirty meters into the chamber.[5][9][13] Because of the difficulty of their expedition and their exploration into the Dinaledi Chamber, the six women were given the name: the Underground Astronauts.[14]

Controversy

Berger's methods in selecting his research team for the Rising Star Expedition did not go uncriticised. The first issue came because of how he called for applicants via Facebook to investigate new hominin remains, leaving experts within the field to question whether or not it was a serious and professional expedition.[13] The second issue came when it came time to analyze of the recovered remains, and Berger once again sent out a call online for those interested, and he specifically looked for early career applicants.[13] Because of this Berger was given the nickname: "Mr. Paleodemocracy".[13] Some other experts began to view the expedition as a media stunt because the process of excavation by the Underground Astronauts was documented daily via blog posts, while Berger spoke on radio shows.[13] The data collected was published in open-access journals and scanned in-order to allow the greatest amount of scientists to access and contribute to the study of the fossil data, which is quite different than the slow and limited access methods taken by most paleoanthropologists.[9] Despite these criticisms, Berger stood by his decisions regarding his excavation and excavation team arguing that he wanted to allow greater access to paleoanthropological research.[13]
