MSL Curiosity is going about its business exploring Mars.
. The high-tech rover is currently exploring the sulphate-bearing unit on Mt. Sharp, the central peak in Mars' Gale Crater. Serendipity placed a metal meteorite in its path.
Even though Mars' atmosphere is much thinner than Earth's, it still creates enough friction to heat the meteorite's surface. The regmaglypts are likely created by vortices of hot gas that melted the rock as it travelled through the atmosphere.Curiosity found the iron-nickel meteorite"Cacao" on 27 January 2023.
Most iron-nickel meteorites come from the cores of shattered planetesimals that formed in the early Solar System. Those objects were large enough to differentiate when they were molten. They formed a core of dense iron and nickel, much like Earth did. That's what makes meteorites, and especially metal ones, so scientifically interesting. They can date back billions of years to the beginning of the Solar System.On Earth, meteorites like Cacao were humanity's first source of iron. Long before smelting, people collected these meteorites when they could and made knives and other implements out of them. King Tut was buried with a dagger made of meteoric iron, and the Inuit people in the Arctic and in Greenland also used meteoric iron.
