NASA’s Curiosity rover recently snapped a captivating photo of a coral-like rock on Mars. This unique formation, about an inch wide, hints at a fascinating geological story dating back billions of years. Scientists believe it formed when water once flowed on Mars, leaving behind clues to the planet’s history.
Curiosity, launched in 2012, has been on a mission to find signs of ancient microbial life on Mars. Each rock it examines helps paint a picture of Mars’ environmental past. On July 24, during its 4,609th day on Mars, Curiosity captured this new coral-shaped rock, notable for its intricate ridges and curves.
Similar rock formations have been documented before. On the same day, another two-inch rock, nicknamed “Paposo,” was found nearby. While unusual, these shapes are common in Mars’ wind-eroded regions. NASA explains that the unique patterns likely came from mineral-rich fluids flowing through cracks in Martian rock, which then hardened over time.
“The minerals left behind tell a story of water’s past here,” NASA points out. This is not the first time Curiosity has discovered odd shapes. In 2022, a flower-shaped rock was found, supporting the idea that underground water once significantly impacted Mars’ landscape.
Curiosity landed in Gale Crater after an extensive journey of 352 million miles. Its primary mission has been to investigate conditions that could have supported life. So far, it has traveled over 22 miles, gathering valuable rock samples and atmospheric data that form a detailed geological timeline of ancient Mars.
As Curiosity explores around Mount Sharp, it continues to reveal a history of water shaping Mars’ environment. While this latest rock discovery doesn’t prove life existed, it raises more questions about the planet’s wet past and its potential for supporting life.
