The martian subsurface has been probed to kilometer depths by the Mars Advanced Radar for Subsurface and Ionospheric Sounding instrument aboard the Mars Express orbiter. Signals penetrate the polar layered deposits, probably imaging the base of the deposits. Data from the northern lowlands of Chryse Planitia have revealed a shallowly buried quasi-circular structure about 250 kilometers in diameter that is interpreted to be an impact basin. In addition, a planar reflector associated with the basin structure may indicate the presence of a low-loss deposit that is more than 1 kilometer thick.
火星快车轨道器搭载的火星地下和电离层探测高级雷达已对火星地下进行了千米深度的探测。信号穿透了极地层状沉积物，可能对沉积物底部进行了成像。来自克里斯平原北部低地的数据显示出一个直径约250公里、浅埋的准圆形结构，被解释为一个撞击盆地。此外，与盆地结构相关的一个平面反射器可能表明存在一个厚度超过1公里的低损耗沉积物。
