Oman-found Martian meteorite returns to Mars as Perseverance's calibration standard

A dark rock found in Oman is SaU 008, a fragment of Mars, and today a slice of it sits on the Perseverance rover as a SHERLOC calibration target. The meteorite’s 300,000-year journey — Mars to Earth and back to Mars — provides a known reference to ground-truth Raman and fluorescence readings and helps monitor the instrument’s response over time, making it an ordinary yet essential tool rather than a mere keepsake.

Record-Breaking Martian Meteorite Sells for $5.3 Million at Sotheby’s

A Maine museum lost its claim to the largest Martian meteorite on Earth after a larger one was found in Niger and auctioned for $5.3 million. The museum's collection, once home to the largest Martian meteorite, now ranks second, but it still holds the world's largest collection of lunar meteorites. The story highlights the rarity and scientific value of Martian rocks, as well as the complex world of meteorite trading.

The Dangers of Magnet Hunting for Meteorites

The use of hand magnets by meteorite hunters to verify the authenticity of meteorites is destroying valuable magnetic information stored within them. The process wipes the pre-existing magnetic field and replaces it with the magnet's own field, making it impossible to study the original magnetism of the meteorite. This poses a problem for scientists hoping to learn about the magnetic field that once shielded the Martian atmosphere. The study suggests that meteorite hunters should skip the magnet test and explore alternative methods to verify meteorites' authenticity.
