Niger is expressing outrage following the auction of the largest piece of Mars, a meteorite that sold for over $5 million at a New York auction. The government claims the rare Martian meteorite was illegally trafficked out of Africa and has launched an investigation into the sale. The auction, which saw the meteorite fetching up to $8 million, has sparked a legal battle and raised concerns about the legality of the sale. Niger has suspended exports of precious stones and meteorites as it seeks answers regarding the sale of this significant space rock found within its borders.
