NASA's Curiosity Mars rover spotted these finger-like rocks with its Mast Camera, or Mastcam, on May 15, 2022, the 3,474th Martian day, or sol, of the mission. These likely formed as groundwater trickled through rock in the ancient past, depositing mineral cements over time; many years later, when the rock was exposed to the atmosphere, wind eroded the softer material around the cemented portions. The rocks were found on Mount Sharp, the 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been climbing since 2014.

Figure A shows a close-up of the finger-like rocks.

Figure B is a 3-D version meant to be viewed through red-blue glasses.

Curiosity was built by NASA's Jet Propulsion Laboratory in Southern California, which leads the mission on behalf of NASA's Science Mission Directorate in Washington. Malin Space Science Systems in San Diego built and operates Mastcam.

1. PPOD: Here is another cool rock at Gale crater on Mars! The spikes are most likely the cemented fillings of ancient fractures in a sedimentary rock. The rest of the rock was made of softer material and was eroded away. 📷:
