The meteorite is smooth as if it was ground on Mars

NASA's Curiosity robot finds an unusual piece of smooth metal meteorite as if it were grinding on the surface of Mars.

The unusual sliver of meteorite called "Egg Stone" was discovered by Curiosity while climbing the Mars Mount Mount in Mars, Science Alert reported yesterday.

Meteors are very popular on the red planet because Mars has a thin atmosphere and is located near the asteroid belt. However, this meteorite is unusually smooth as if it is grinding and has some deep grooves, which may be a trace of ever melting.

Curiosity robot approached and photographed the structure of meteorite with ChemCam Remote Micro-Imager device for NASA scientists to analyze components. They claim that the meteorite is composed mainly of nickel and iron, originating from the core of an object in the asteroid belt. The objects in this belt often collide with Mars after being shot away by Jupiter's gravity.

Based on the shape, the researchers speculate that a 4-meter-wide metal meteorite melts as it passes through Mars's atmosphere and hardens after landing.

Mars is less affected by weathering and oxidation than the Earth, so meteorites on the planet's surface are also kept in better condition. Curiosity is moving around the base of Mount Sharp and continues its journey to find evidence of life on the red planet.
