> These ripples were imaged by Curiosity on Sol 3684 (Dec. 16, 2022). (Image credit: NASA/JPL-Caltech/MSSS) The caption on the second image of this space.com article is misleading. This photo does not show ripples, it is showing the particular ripple-bearing thin laminations in this sedimentary rock, exposed here as "edges". The journal article shows this photo [Fig 2. C] with an annotation line identifying the particular strata containing the ripples. The ripple-bearing unit is 15cm thick and is the thinly bedded strata below the piled sand. If you're interested, the actual paper is predictably much more informative than this shallow space.com article: https://www.science.org/doi/10.1126/sciadv.adr0010 https://www.science.org/doi/10.1126/sciadv.adr0010
