New Delhi: In a rare cosmic event, the largest known fragment of Mars ever to land on Earth officially designated NWA 16788 is about to make history at Sotheby’s Natural History auction in New York on July 16. This monumental meteorite, weighing an impressive 24.5 kg (54 pounds), dwarfs all previously discovered Martian rocks, being 70% larger than the next biggest specimen.
Discovery in the Niger Desert
The story of NWA 16788 began in November 2023, when a meteorite hunter uncovered the massive stone in the remote Agadez region of Niger. Its sheer size and excellent preservation immediately set it apart from the typical small Martian fragments that survive the journey through Earth’s atmosphere. Experts estimate the meteorite could command a price of $2–4 million (Rs 17–34 crore) at auction, making it one of the most valuable meteorites ever offered.
What Makes NWA 16788 So Special?
- Extraordinary Size and Rarity: Of the nearly 80,000 meteorites cataloged on Earth, only around 400 have been confirmed as Martian in origin. Most are tiny, but NWA 16788 alone accounts for over 6% of all Martian material ever found on our planet.
- Scientific Significance: Classified as a shergottite, this meteorite likely originated from volcanic regions on Mars and was ejected by a massive asteroid impact millions of years ago. Its minerals, some turned to glass, and its glassy fusion crust provide a window into Martian geology and the violent journey through space and Earth’s atmosphere.
- Visual Appeal: The meteorite’s deep red hue and glassy surface are not only visually striking but also offer clues about its Martian origins and the processes it endured before landing on Earth.
Scientists’ Concerns Over Auction
While collectors and enthusiasts eagerly await the auction, many scientists are uneasy about such a rare specimen entering private hands. Researchers argue that every Martian meteorite, especially one as significant as NWA 16788, holds invaluable scientific data that could advance our understanding of Mars. There is concern that private ownership could restrict access for further study, although a reference sample has been preserved at the Purple Mountain Observatory in China to ensure continued scientific analysis.
