When Kate Middleton handled a small piece of rock at London’s Natural History Museum, she joined a select group of individuals who have touched a meteorite. These rare extraterrestrial fragments not only offer scientists crucial insights into the solar system but also hold significant value in the market.
The most expensive meteorite on record, NWA 16788, a Martian meteorite weighing 54 pounds, was sold for $5.3 million (£3.9m) at Sotheby’s in New York earlier this year. This sale underscores the growing competition among meteorite enthusiasts and collectors.
Meteorite hunting is on the rise, partly due to the proliferation of Ring doorbells, car dashcams, and phone cameras that capture meteorite sightings. While such occurrences are rare in the UK, the Winchcombe meteorite, a unique 4.6 billion-year-old specimen that fell in Gloucestershire in February 2021, was captured on doorbell cameras, marking the first meteorite recovery in the country in three decades.
Professor Sara Russell, who leads the Planetary Materials Group at the Natural History Museum, explains that meteorites are rocks that have landed on Earth from space, with most believed to originate from asteroids. The UK Fireball Alliance (UKFall), a network of meteor cameras across the UK, plays a vital role in spotting meteorites and engaging citizen scientists in the search.
Dr. Helena Bates, also part of the Planetary Materials Group, praises networks like UKFall for facilitating citizen science and community engagement, leading to increased interest in meteorite studies. The recent surge in space exploration missions, such as Hayabusa, Hayabusa2, and OSIRIS-REx, bringing asteroid samples to Earth, has further fueled public curiosity about meteorites.
Meteorite discoveries in the UK are challenging due to the landscape and weather conditions, which often obscure fallen meteorites. However, the rapid collection of the Winchcombe meteorite, aided by camera footage and citizen scientists, highlights the potential for more frequent meteorite finds in the future.
Meteorites are invaluable to scientists, offering insights into the formation of the solar system billions of years ago. They contain clues about temperatures, conditions, and processes during that era, shedding light on our cosmic origins and planetary evolution.
While the exact number of meteorites landing on Earth remains unknown, the interest in acquiring and collecting them is growing. Darryl Pitt, curator of the Macovich Collection, emphasizes the importance of sourcing meteorites from reputable sellers to avoid purchasing common earth rocks or man-made objects posing as meteorites.
The trade and ownership of meteorites are subject to varying laws and regulations worldwide, with some countries strictly prohibiting their export. The scarcity of rare meteorite specimens poses challenges for scientific research and museum acquisitions, potentially hindering advancements in space exploration and industry planning.
Despite the commercialization of meteorites, many hunters make samples available to scientists, contributing to valuable scientific research. However, balancing accessibility for scientific study and commercial interests remains a critical consideration in the meteorite community.
