Study Finds An Ancient History Of Water On Mars That Shifted Over Time

by Keith CowingSeptember 23, 2026September 23, 2026

[Purdue University] From orbit, a carbonate-rich band of rock along the inside edge of Mars’ Jezero Crater looked like it might be the remains of an ancient lakeshore. Then NASA’s […]

PIXL micro-XRF observation from the third “Apollo Temple” scan (a,b), alongside a SHERLOC WATSON color image for context (c). An RGB composite shows the areas with relative enrichment of FeOT, SO3, and SiO2 where brownish tones highlight Fe-sulfide (a). Zones of Ni enrichment are seen in yellow (b) and marked with white arrows (a,b,c). Dashed black box shows the approximate area of the PIXL scan (c). Image Credit: NASA/JPL-Caltech.
