Tissint Meteorite 1.674g Slice

Martian, shergottite
Witnessed fall in Oued Drâa valley, Morocco, July 2011

A Rare Witness to Martian Volcanism
Martian meteorites are among the most elusive substances on our planet, but the subgroup of witnessed falls holds a place of even greater distinction. These extraordinary specimens were observed streaking across the sky before their recovery, allowing for immediate collection and preservation of their original cosmic state. Each Martian shergottite in this category represents a piece of volcanic crust launched from the Red Planet by a colossal impact millions of years ago. To possess a fragment of a witnessed fall like Tissint is to hold a celestial messenger in its most pristine form, capturing the energy of its journey while it remained untouched by the slow work of terrestrial weathering.

The Pristine Mineralogy of the Red Planet
Within this elite category, the importance of geological “freshness” provides a critical window into planetary science. Witnessed falls preserve delicate internal features—such as maskelynite glass and subtle isotopic signatures—that might otherwise be altered by prolonged exposure to Earth’s environment. These Martian meteorites offer a look into the magmatic evolution of a world that humanity has only just begun to explore through robotic missions. For the discerning collector, these specimens are more than rare objects; they are finite scientific records that bridge the vast silence of space between Earth and the Red Planet, offering a tangible connection to our neighbor in the solar system.
