In 2022, a pinkish-hued meteorite was discovered in the Sahara Desert, its origin and age initially remaining unknown. Scientists working with financial support from NASA conducted dating of minerals comprising the sample and established that the stone weighing nearly 800 grams (about 2 pounds) is a fragment of Mars. According to the data obtained, the meteorite formed more than 4.1 billion years ago, in the earliest period of the Solar System's history. This makes the discovery one of the oldest known Martian meteorites ever found on Earth. Such specimens are of great scientific value, as they allow researchers to study early geological processes on Mars, including the formation of its crust and possible conditions that existed on the planet billions of years ago. Analysis of the meteorite's mineralogical composition and isotopic characteristics helps scientists reconstruct the history of the Martian surface during the period preceding the formation of large impact craters and volcanic plains. The research underscores the importance of meteorite discoveries in desert regions, such as the Sahara, where the dry climate contributes to good preservation of extraterrestrial material. The results of the work, supported by NASA, provide additional data for understanding Mars's early evolution and may be used in planning future missions to study the planet, including analysis of samples retrieved from its surface.
