Key takeaways

Scientists confirmed that the 800-gram rose-colored Teghaza 001 meteorite landed on Earth from Mars.
The rock originated over 4.1 billion years ago during the Noachian era on Mars.
Search teams discovered this fragment in 2022 within Teghaza, Mali, in the Sahara Desert.
Geochemical evidence inside the meteorite proves that liquid water flowed through the Martian crust billions of years ago.

A NASA-funded research study in the journal Science verified that a rare rose-colored meteorite named Teghaza 001 came directly from Mars.
The meteorite weighs 800 grams and was initially discovered in the Sahara Desert in 2022.
Scientific measurements reveal that this space rock formed on Mars more than 4.1 billion years ago.

This unique 800-gram pinkish rock represents an undisturbed sample of the original surface layer of Mars.
It belongs to a small group of roughly 435 confirmed Martian meteorites located on Earth.
Geologists consider this discovery a key key to understanding the earliest geological history of Mars.

The rock formed when liquid magma cooled inside the crust of Mars during its ancient Noachian era over 4.1 billion years ago.
Data from NASA's Mars Reconnaissance Orbiter (MRO) matched the rock to 13 potential landing sites on Mars, mainly in its southern highlands.
A powerful asteroid or comet impact knocked the rock off Mars, sending it through space until it fell to Earth.

Searchers located the rock in 2022 near Teghaza, Mali, inside the Sahara Desert.
Tests at the University of New Mexico checked its oxygen elements to confirm its origin from Mars.

The rock has a pink color and holds various volcanic minerals that show how the crust of Mars developed.
Tiny zircon crystals inside the rock preserve structural details that helped scientists calculate its exact age.
Researchers applied a precise rubidium-strontium dating method to inspect mineral grains without damaging the sample.
Chemical traces inside the meteorite confirm that liquid water moved through the Martian crust around 4.1 billion years ago.
The sample contains clues about how the surface rocks, water, and air of Mars affected each other long ago.

The findings prove that ancient Mars had flowing water, which helps scientists judge if simple life could have existed there.
Having a real piece of Mars allows scientists to run direct laboratory tests on Earth without waiting for space missions to bring back samples.
