Critical signature sound when rocks crack
Finding the specific sound a rock makes when it cracks and breaks seems impossible when surrounded by other subsurface noises. But Texas A&M University researcher Dr. Siddharth Misra, the Ted H. Smith, Jr. ’75 and Max R. Vordenbaum ’73 DVG Associate Professor in the Harold Vance Department of Petroleum Engineering, discovered a way to hear […]
Advanced analysis of Apollo sample illuminates Moon’s evolution
Sophisticated analysis of a rock sample taken from the Moon during the Apollo 17 mission revealed new information about the complex cooling and evolutionary history of the Moon. The findings, from University of Hawai’i (UH) at Manoa researchers, were published today in Nature Communications. Apollo 17 astronauts collected the rock sample troctolite 76535 from the […]
Early molten moon’s deep secrets
Shortly after it formed, the Moon was covered in a global ocean of molten rock (magma). As the magma ocean cooled and solidified, dense minerals sank to form the mantle layer, while less-dense minerals floated to form the surface crust. Later intense bombardment by massive asteroids and comets punched through the crust, blasting out pieces […]
