New satellite data from Indian’s moon mission Chandrayaan-1 has revealed a good amount of historic tectonic activity on the lunar surface, very similar to that on Earth . Scientists studying geological processes on the lunar surface now report faults and grabens in partially and completely shadowed crater interiors of the lunar polar regions.

Saumitra Mukherjee of the School of Environmental Sciences at Delhi’s Jawaharlal Nehru University along with colleague Priyadarshini Singh investigated data from the microwave sensor (MiniSAR) of the Chandrayan- 1 satellite using the image analysis software ENVI.

“The geological processes on the moon are marked with various tectonic features suggestive of similar geological activity occurring on the Earth,” Mukherjee told Nature India. He said the tectonic activity could have been generated by cosmic rays and solar wind flux variability coupled with some interior tectonic activity and meteorite impacts.   …more
