NASA's Curiosity rover spots unexpected rock textures while hunting for minerals on Mars
Mission scientists report a shift from finely layered bedrock to new rock textures as Curiosity continues exploring Mars' sulfate-rich terrain.

NASA's Curiosity rover surprised mission scientists this week with a notable change in the rock textures found at its current Mars worksite, according to a mission update written by planetary scientist Lucy Lim of NASA's Goddard Space Flight Center.
For the Earth planning date of September 18, 2026, the team described how, instead of the finely layered bedrock blocks the rover had been examining in its recent sulfate unit workspaces, Curiosity encountered a markedly different rock texture, prompting renewed interest from the science team.
Hunting for minerals in changing terrain
Mission scientists use changes in rock texture as clues to the geological history of the areas Curiosity explores, since different textures can point to different conditions under which the rocks formed, including the presence of specific minerals.
The rover's onboard instruments allow the team to analyze these formations in detail, helping scientists piece together how the Martian sulfate-rich terrain developed over time and what it may reveal about the planet's past environmental conditions.
The mission update is part of NASA's ongoing public reporting on Curiosity's work as it continues its long-term exploration of Mars' surface, with the team continuing to assess the newly observed textures in the days following their initial discovery.
