Geologic History, Earth and Mars

Author: Hugh Bollinger/Thursday, May 18, 2017/Categories: natural history, photography, space science, art and design, environment, adventure

As more and more satellite images are acquired from Mars, striking comparisons between the Red Planet and Earth become possible. NASA has shown just how similar by comparing pairs of geologic images. One example are rock structures thrusting from the flat, dry, landscapes of northwestern New Mexico and from a Martian desert plain.

Protruding from the New Mexico desert the extinct, volcanic spire of Shiprock, a "plug" of lava rock, is compared to dry landscape terrains on Mars. Volcanic activity on Mars created similar razor-like, shapes visible as virtical, triangular walls.

Additional geological research will add to an understanding of how similar and for how long such processes worked on Mars and if they are still in progress.
