Alam Ki Khabar | Bihar News | Patna News | Samastipur News | Scientists have studied Teghaza 001, a 4.1-billion-year-old Martian meteorite found in Mali. Its minerals reveal evidence of water deep beneath the surface of ancient Mars.

October 31, 2026:


A remarkable discovery in the Sahara Desert is offering scientists a rare glimpse into the distant past of Mars. Researchers have studied a reddish meteorite recovered in Mali and found that it formed at least 4.1 billion years ago. Named Teghaza 001, the rock carries important clues suggesting that water once moved through the deeper layers of the Red Planet.


The discovery could help scientists better understand how Mars evolved from a potentially warmer and wetter world into the cold, dry planet we know today.


Teghaza 001: A Rare Martian Rock


The meteorite was discovered in Mali’s Sahara region in 2022. Scientists later identified it as a rock originating from Mars. Its age makes it one of the oldest Martian meteorites ever recovered on Earth.


According to research published in the journal Science, the meteorite contains a distinctive combination of minerals that preserves evidence of the planet’s early geological history. The recovered material weighs nearly 800 grams in total and consists of several pieces.


Researchers examined tiny mineral grains within the rock to establish its age. Zircon crystals proved particularly important because their radioactive elements can help scientists determine when a rock formed.


Minerals Reveal Evidence of Ancient Water


The most significant finding is the evidence of interaction between water and molten rock deep beneath the Martian surface.


Scientists detected chemical and isotopic signatures involving hydrogen and oxygen in the meteorite’s minerals. These clues indicate that water had seeped into the Martian crust and interacted with hot rocks as they cooled and crystallised.


The findings suggest that liquid water was present on Mars more than 4.1 billion years ago. They also provide insight into how water moved through the planet’s early crust and how Mars gradually changed over geological time.


NASA Scientist Highlights the Importance of the Discovery


Planetary scientist Yang Liu of NASA’s Jet Propulsion Laboratory led the research into the meteorite’s age and characteristics. Scientists believe Teghaza 001 could become an important sample for understanding the early atmosphere, crust and geological evolution of Mars.


The research supports the possibility that ancient Mars once had environmental conditions suitable for microbial life. However, scientists have not found proof of life in this meteorite. Evidence of water alone cannot establish that living organisms existed on the planet.


A New Window Into Mars’ Early History


Researchers believe the meteorite may have originated in the southern highlands of Mars, although its exact source location has not yet been confirmed. An enormous impact on Mars is thought to have blasted the rock into space, from where it eventually travelled to Earth and landed in the Sahara. Scientists do not know exactly when it fell to Earth.


Further examination of Teghaza 001 may reveal more about the planet’s ancient water systems, volcanic activity and changing atmosphere. For researchers, this small piece of rock is an unusually valuable record of a time when Mars may have been very different from the world seen today.
