Insights from interior monologue of Mars
ON TUESDAY, InSight, NASA's Martian exploration device, successfully landed on its destination site. Guokr.com comments:
Unlike its predecessors that stressed exploring the surface of Mars or analyzing its atmosphere, InSight focuses on in-depth underground exploration of the red planet. For that purpose, it carries devices that can collect earthquake (or, more exactly, Marsquake) shock wave data and do thermal imaging of its inner structure.
Some might ask why the inner structure of Mars is so important to us. The answer is simple: Because the geological structure of Mars contains the records of the planet's evolution over billions of years, which in turn reflect its long history and might provide an answer to the origin of life on Earth.
