NEW: 1.4g Genuine Martian Meteorite - Scientifically Studied Rock From Planet Mars w/ Aqueous Alteration - NWA 18281

You are viewing the newest genuine Martian meteorite brought to the Interstellar market that originated on Planet Mars. This is a true chunk of the Red Planet, studied by leading scientists in the field of Meteoritics. It has been determined that this stone has evidence of aqueous alteration present within the pyroxenes that occurred while on its parent body. This signifies something we’ve already known to be true, but fascinating nonetheless - the presence of water on Mars. This is surely a front-of-display meteorite in your collection. *scale cube for reference only How do we know it’s from Mars? Like the Moon, Mars experiences frequent asteroid and meteoroid impacts. Some of these collisions are powerful enough to eject Martian rock beyond the planet’s gravity and into interplanetary space. On rare occasions, these fragments are sent into Earth-crossing orbits. If a fragment survives its fiery passage through Earth’s atmosphere and reaches the ground, it becomes known as a meteorite. When a suspected Martian meteorite is recovered—often by experienced meteorite hunters—a sample is submitted for scientific analysis. Using petrographic thin sections, chemical testing, and isotopic studies, Meteoriticists compare the specimen's composition to known planetary materials. Its Martian origin is then confirmed through a combination of mineralogical, chemical, and isotopic signatures. Once classified, these rare extraterrestrial specimens find their way into museums, universities, research collections, and private collections around the world. But the most definitive evidence comes from gas trapped inside the rock! Martian meteorites contain tiny bubbles of gas sealed within glassy inclusions. When analyzed using mass spectrometry, the gas composition matches the Martian atmosphere exactly as measured directly by NASA’s Viking landers in the 1970s and confirmed by later missions like Curiosity. The match is so specific that there's no other natural source on Earth (or elsewhere) with the same gas profile. The Interstellar Collection offers a wide array of genuine, scientifically-classified Martian meteorites. The Interstellar Collection, LLC is acknowledged by the IMCA (#3950), the Global Meteorite Association (GMA #042) and the Meteorite Club. We unconditionally guarantee the authenticity of all of our meteorites.
