火星探査機InSightに積まれた地震計に記録されたDataうぃ解析して、火星表面の地図を作成する計画です。

NASA's Mars InSight lander provided researchers with the data needed to give us our first detailed look at the red planet's crust, mantle and core. That map doesn't include any information on the structures nearer its surface, however, and we need that to be able to get a more complete picture of how the planet was formed. Now, a team of scientists was able to create the first detailed image of what lies right underneath the planet's surface, showing three billion years of its history, by listening to Martian winds.
