NASA’s Mars Curiosity rover finds evidence of high-frequency wet-dry cycling in the Gale Crater. New observations of mud cracks made by NASA’s Mars Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments, indicating that the red planet may have onc
Patterns in mud cracks show that Mars may have had cyclical moisture patterns. Left: the terrain in the Gale Crater where Curiosity is currently exploring. Right: mud cracks on Earth, where wet-dry cycling has occurred, creating Y-shaped patterns.
After years of exploring terrain largely comprised of silicates, the rover entered a new area filled with sulfates, marking a major environment transition. In this new environment, the research team found a change in mud crack patterns, signifying a change in the way the surface would have dried. This indicates that water was still present on the surface of Mars episodically, meaning water could have been present for a time, evaporated, and repeated until polygons, or mud cracks, formed.
