US EditionCuriosity Rover Reveals Coral-Like Rock Paposo as Ancient Mineral Vein
GALE CRATER, MARS, AUG 11 – The Curiosity rover discovered coral-shaped rocks formed by mineral-rich water and wind erosion billions of years ago, supporting evidence of ancient habitable conditions on Mars.
- On Aug. 4, NASA released an image from the Curiosity rover’s Remote Micro Imager showing a roughly one inch coral-like rock inside Gale Crater discovered on July 24, 2025.
- NASA explains that coral-shaped rocks on Mars started forming billions of years ago when water carried dissolved minerals into cracks, then dried and was sculpted by wind.
- Earlier this week, NASA said, 'Remarkably, the boxwork patterns show that even in the midst of this drying, water was still present underground, creating changes seen today,' based on Curiosity's findings of small features formed billions of years ago.
- Despite its coral-like look, NASA clarified the formation shows no signs of life on Mars.
- Space.com reports that the Curiosity rover continues to adapt with remote fixes and new software upgrades allowing multitasking and early power-down, extending its mission, NASA said.

NASA Finds Multi-Billion-Year-Old ‘Coral’ Structures on Mars
Coral-shaped formations discovered on Mars by Curiosity. Credit: NASA / JPL-Caltech / MSSS A delicate rock formation resembling coral has been spotted on Mars, according to images sent back by NASA’s Curiosity rover. Although it mimics the branching shape of coral seen in Earth’s oceans, scientists confirmed the structure is the result of natural geological processes unique to the Martian environment. The unusual rock was discovered on July 24 i…
NASA's Curiosity Rover is surprised by what appears to be a coral reef on the planet Marte. Researchers have highlighted the mystery and explain that the strange object is, in fact, a small, open-coloured rock, wind-red, which the Rover found in the Gale crater, on the Red Planet, on July 24, shows Live Science.
