So the final report is due by 30 April 2030.

Abstract

Nearly 1,800 miles below Earth’s surface, the rocky mantle meets the liquid iron core. Heat escaping the core stirs the slow churning of the solid mantle above driving plate tectonics, earthquakes, and volcanoes at the surface. Just above the Earth’s core sits a thin, mysterious layer known as D″ (“D double prime”). Mapping the characteristics of this layer is key to learning how much heat leaves the core and…
