Planet Mercury Found to Be Tectonically Active
Tucson AZ (SPX) Sep 28, 2016
Images acquired by NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft show geologic features that indicate Mercury is likely still contracting today, joining Earth as a tectonically active planet in our solar system. Previously undetected small fault scarps were observed in images collected during the MESSENGER mission's final 18 months in orbit around Mercury, according to a new paper in Nature Geoscience [http://www.nature.com/ngeo/index.html]. During the ... read more
