New Scientist says it is "probably the most ambitious seismological project ever conducted."
It is USArray. Part of the EarthScope project, it is a 15-year program to install an intricate network of portable and permanent seismographs across the continental United States. It's mission: to listen to the deep murmurs of the Earth, giving us an unprecedented view of what it looks like down there -- and what causes earthquakes and forms volcanoes.
Operating like a massive ultrasound, USArray will scan up to 2,900 kilometers (1,800 miles) below the surface of the Earth, to where the mantle meets the core, and maybe even further.
Now that's going deep.
