NASA’s Curiosity rover has despatched again intriguing photographs of what appears like a chunk of coral on Mars.
The unusual object is actually a small, light-colored, wind-eroded rock, which the rover discovered contained in the Red Planet’s Gale Crater on July 24 — nevertheless it appears remarkably much like the reef-building creatures present in Earth’s oceans.
A black and white image taken with Curiosity’s Remote Micro Imager — a high-resolution, telescopic digicam that’s mounted on the rover — and shared by NASA in a statement on Aug. 4 exhibits the roughly 1-inch-wide (2.5 centimeters) rock with its intricate branches.
“Curiosity has found many rocks like this one, which were formed by ancient water combined with billions of years of sandblasting by the wind,” NASA representatives wrote within the assertion.
Coral-shaped rocks on Mars began forming billions of years in the past, when the Red Planet nonetheless had water, based on the assertion. Just like water on Earth, this water was stuffed with dissolved minerals. It percolated by means of small cracks in Martian rocks, regularly depositing minerals and forming strong “veins” contained in the rocks.
These veins type the unusual branches of the coral-shaped object that we see in Curiosity’s image right this moment, after tens of millions of years of abrasion by sand-laden winds wore away the rock.

Other examples of surprising rocks discovered on Mars embody “Paposo” — a strangely-shaped rock measuring about 2 inches (5 cm) throughout that Curiosity also discovered on July 24 — and a tiny, flower-shaped object, which the rover photographed in Gale Crater in 2022.
Curiosity landed on Mars in 2012, touching down within the Gale Crater — a meteor impression crater on the boundary between the Red Planet’s cratered southern highlands and its clean northern plains. The rover’s mission, led by NASA’s Jet Propulsion Laboratory in California, is to scan the Martian floor for any indicators that it was liveable at any level within the distant previous.
So far, Curiosity has traversed roughly 22 miles (35 kilometers) of the 96-mile-wide (154 km) crater. Its path is meandering and gradual, as a result of it has to cease to drill into rocks, acquire samples and collect information.
The rover’s explorations have uncovered considerable proof that the potential for all times as soon as existed on Mars, together with lengthy carbon chains from 3.7 billion-year-old rocks and indicators that Mars as soon as had a carbon cycle.
