The instrument—the Mars Advanced Radar for Subsurface and Ionosphere Sounding, or MARSIS【C12】______—emits radio waves toward the planet. The waves penetrate the Martian surface and bounce off【C13】______material they come in contact with, then reflect back to the spacecraft.

Starting in May 2012, MARSIS【C16】______more than three years pinging a region at Mars with radio waves.【C17】______helps to look at the data yourself.
