A unique meteorite, which is the largest known fragment of Mars on Earth, will be auctioned by Sotheby's in New York on July 16, 2025. Its price is expected to reach up to $4 million. This meteorite, known as NWA 16788, weighs an impressive 24.5 kg, making it significantly larger compared to most Martian meteorites, which are usually small fragments. According to Sotheby's, it is about 70% larger than the next largest piece of Mars ever found on Earth. This is an incredibly rare occurrence, as only about 400 Martian meteorites have been found on our planet.
The analysis of the meteorite's internal composition showed that it was likely torn from the surface of Mars and ejected into space due to a collision with an asteroid that was so powerful that it turned parts of the meteorite into glass. Its surface also reveals a glassy crust formed during its passage through the Earth's atmosphere. The fact that such a unique specimen is being sold raises concerns among some scientists. However, Julia Cartwright, a planetary geologist and independent research fellow at the Space Institute at the University of Leicester, notes that there is a 'symbiotic relationship' between researchers and collectors. 'If there wasn't a market for the search, collection, and sale of meteorites, there wouldn't be so many in our collections - and this drives science!', she said.
Conclusion: The unique Mars meteorite, weighing 24.5 kg, will be auctioned in New York with an estimated price of up to $4 million. This rare specimen may help science better understand the processes occurring in space and exemplifies the 'symbiotic relationship' between the scientific community and meteorite collectors.
