Two Mines researchers have been awarded NASA grants to work on an “out-of-this-world” extraction technique called optical mining. Mechanical Engineering Assistant Research Professor Christopher Dreyer and Director of the Center for Space Resources Angel Abbud-Madrid are developing novel technologies to obtain valuable resources from asteroids, which can be used as rocket propellants.
“The optical mining concept is very exciting because it is a large-scale approach for producing resources in space that can be attempted soon,” Dreyer said. “We are contributing experimental evidence for the conditions under which intense light will disassemble carbonaceous chondrite asteroids.”
Optical mining will use concentrated solar energy to heat and fracture asteroids causing them to release volatile elements. These resources will be extracted and used in space to avoid the high cost of transporting them from Earth.
Mechanical engineering student Alexander Lampe and engineering physics student Travis Canney are helping with this research by preparing vacuum chambers for experiments, designing the test matrix, writing experimental procedures and running tests.
Their research project is funded by a $500,000 grant for “Laboratory Demonstration and Test of Solar Thermal Asteroid ISRU,” by the NASA Early Stage Innovations program and a $125,000 grant for “Demonstration of Optical Mining for Excavation of Asteroids and Production of Mission Consumables,” by the NASA Small Business Innovation Research program.
Mines researchers are working in this multidisciplinary effort with Missouri University of Science and Technology Professor Leslie Gertsch (Mines alumna GE ’82, PhD ‘89) and TransAstra Corporation Founder & Principal Engineer Joel Sercel. Other research participants include the University of Hawaii.
Mines’ research efforts were recently highlighted in Space.com, SpaceDaily, Sputnik International and Missouri S&T.
