a, Sub-ice topography, corrected for isostatic rebound due to ice removal3, with sharp topographic features enhanced by nonlinear filtering (Methods). The light grey lines are detected topographic lineaments interpreted as longitudinal normal faults forming the structural edges of the basins. The magenta and cyan lines represent detected topographic lineaments interpreted as either transverse strike–slip faults or associated normal faults that characterize the two circular shear belts shown in b (that is, the southern and northern TSCBs).

Drone Radar Reveals Buried Glaciers On Earth, Guiding The Search For Water On Mars

by Keith CowingMay 1, 2026May 1, 2026

Understanding how to explore hidden glaciers on Mars begins not in a laboratory, but in remote field camps across Alaska and Wyoming.

(a) Stratigraphic column demonstrating the location of the second aquifer implemented in this section. (b) Ht across entire receiver array. The wide RIR signal arrival between 3 and 6 s is comprised of RIRs from the top of the lower aquifer and both interfaces of the shallower, newly placed aquifer. (c) Vr from receiver at x = 0. (d, e) Er and Ht, respectively. The addition of the new SE sources from the second aquifer is evident in the more complex RIRs. -- Computational simulation/modeling

Marsquakes May Help Reveal Whether Liquid Water Exists Underground On Mars

by Keith CowingJune 26, 2024June 26, 2024

If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars — […]
