A rare Martian meteorite is making headlines. Known as NWA 16788, this meteorite weighs a hefty 54 pounds (about 24.5 kilograms). It’s the largest piece of Mars ever found on Earth and could sell for as much as $4 million at an auction later this month.
Discovered in November 2023 in Niger’s Agadez region, NWA 16788 is significantly larger than other Martian meteorites, some of which are mere fragments. In fact, it’s about 70% larger than the next biggest Martian meteorite. Only around 400 such meteorites have ever been identified on our planet, making this one exceptionally rare.
Cassandra Hatton from Sotheby’s describes it as a “once-in-a-generation find.” Its unique red color and massive size make it a standout piece. The meteorite was likely blasted into space by an asteroid impact, which also turned parts of it into glass. This journey through space has weathered its surface, creating a glassy crust after passing through Earth’s atmosphere.
The auction will take place at Sotheby’s in New York on July 16. However, hosting an auction for such a significant piece of space history has sparked debate. Some, like Steve Brusatte, a paleontologist at the University of Edinburgh, voice concerns that the meteorite should end up in a museum for public benefit and study.
On the flip side, Julia Cartwright, a planetary scientist at the University of Leicester, believes that the market for meteorites supports scientific research. She suggests that selling meteorites helps fuel discoveries and that private collectors often contribute to scientific knowledge.
Historical context shows that interest in Martian meteorites has grown in recent years. For instance, in February 2021, another Martian meteorite fetched $200,000 at auction, which was well above its expected price of $30,000 to $50,000.
As NWA 16788 approaches its auction date, many are watching closely to see where it will end up—and what secrets it may reveal about Mars in the future. Scientists hope that, regardless of the auction outcome, this remarkable find will continue to inspire curiosity about our neighboring planet.
