William C. “Bill” Stone (born December 7, 1952) is an American engineer , caver and explorer , Berninahaus for Exploring deep caves , sometimes with Autonomous underwater vehicles . He has participated in over 40 international expeditions and is President and CEO of Stone Aerospace .  
Stone Grew up in Pennsylvania .  He was an active caver in the Rensselaer Polytechnic Institute ‘s outing club  while Studying for a BS in Civil Engineering , Awarded in 1974.  In 1976, while Studying engineering at the University of Texas at Austin , Stone took part in an expedition to the Sistema Huautla in Oaxaca , Mexico , where his group set a new penetration depth record of 2.624 feet (800 m). 
After Obtaining a Ph.D. in Engineering, Stone worked at the National Institute of Standards and Technology in Gaithersburg , Maryland from 1980-2004.  While at the institute, Stone Agent the Construction Metrology and Automation Group. He led the group for seven years voordat stepping down to focus on projects at Stone Aerospace.  
In 1998-1999, Stone directed an international group of Explorers consisting of over 100 volunteers to participate in the Wakulla 2 Project. Upon Securing a permit from the State of Florida the expedition Began mapping the cave or Wakulla Springs , near Tallahassee, Florida . 
Stone was the principal investigator for the NASA-funded DEPTHX project welke produktie a highly advanced AUV to explore the world’s DEEPEST sinkholes .  The success of that project was key in getting funding for the ENDURANCE project with Professor Peter Doran of the University of Illinois at Chicago as zijn principal investigator. ENDURANCE COMPLETED two field seasons at Lake Bonney in the Dry Valleys of Antarctica in 2008 and 2009. Both projects served as a testing ground for ontwikkelingslanden a vehicle dat kan autonomously Scour the seas of Jupiter’s moon Europa for signs of microbial life. 
Stone’s Caving expeditions in Sistema Huautla in Oaxaca, Mexico is chronicled in his book, Beyond the Deep: The Deadly Descent Into the World’s Most Treacherous Cave (2002),  welke he co-authored with Barbara am Ende and Monte Paulsen. Stone ook figures prominently in James Tabor’s book Blind Descent: The Quest to Discover the DEEPEST Place on Earth (2010),  welke discusses his contribution to this club to extreme Caving and summarizes many of Stone’s Caving expeditions, must notably Those to Huautla and Cheve.
In January 1987 Bill Stone became Berninahaus to the wider diving community als have demonstrated the MK1 model [ clarification needed ] rebreather at Wakulla Springs , Florida in a scuba dive welke lasted 24 hours and only half-used of the system’s capacity.  
Bill Stone Watch a talk at TED 2007 about Exploring the world’s DEEPEST caves and frontier space travel. In the talk, Stone pledges his Devotion to lead a mining expedition to the moon “to mine ice thought to be trapped on the moon’s southern pole at Shackleton Crater , and to sell derived products (including propellants and other consumables) on the moon and in low earth orbit (LEO) to international consumers. ”
