Which means you can't hear the hum. The sound of Mars Philippe Lognonne of the University of Paris said a proposed future mission to Mars, known as NetLander and expected to launch between 2005 and 2007, would explore the seismic waves of the Red Planet and their possible connection to the atmosphere. It is clearly a technical challenge, but it might be possible. Studying how the seismic waves move through subsurface layers of different composition would help scientists determine the diameter of the planet's core and whether it is solid or liquid. A set of four meteorology stations would monitor the martian atmosphere and how it interacts with the surface.
