NASA map identifies 13 possible origin sites on Mars for ancient meteorite Teghaza 001
NASA released a global map identifying 13 potential launch points on Mars for Teghaza 001, one of the most ancient Martian meteorites discovered on Earth. Added to NASA's Photojournal on October 29, 2026, the map combines spacecraft measurements to trace where the rock likely formed before being blasted into space. Scientists cannot prove an exact point of origin for space rocks that land here, but mineral and chemical clues point directly toward the rugged highlands across the southern hemisphere of Mars. Researchers matched the rock's composition against orbiter survey data. For anyone interested in planetary history, pinpointing where Martian meteorites came from helps scientists link physical samples tested in Earth laboratories to specific geographical regions on Mars. This offers a rare ground-level check on the planet's earliest geological past without having to send a return mission to that exact spot.
What was announced
NASA published an image, credited alongside JPL-Caltech and the USGS, mapping 13 spots across Mars that match the chemical and mineral makeup of meteorite Teghaza 001. The rock is described as one of the most ancient Martian meteorites recovered on Earth.
To create the map, scientists relied on observations collected by two different spacecraft missions. They built the underlying global elevation map using data from the Mars Orbiter Laser Altimeter, an instrument carried on NASA's Mars Global Surveyor mission. They then identified the 13 candidate sites, marked on the image with white circles, using observations from NASA's Mars Reconnaissance Orbiter.
What it means
Space rocks found on Earth rarely come with an address. While scientists can examine Martian meteorites up close in a laboratory, tying them to a specific crater or region on Mars is difficult. The announcement states that researchers can never know with absolute certainty where any Martian meteorite began its journey.
Even so, the chemical and mineral data narrow the possibilities. The data links Teghaza 001 to highland regions in the southern hemisphere of Mars. By matching satellite readings to the physical composition of the meteorite, researchers can connect physical specimens in terrestrial labs to broader geological regions on another world.
What the announcement does not tell us
The release leaves out many basic details about the rock and the study behind it. It does not state when, where, or by whom Teghaza 001 was found on Earth. It does not specify its exact age, its size, or the specific minerals and chemical elements that define it.
The text also omits the names of the individual scientists who conducted the analysis. Furthermore, NASA does not explain what impact or event ejected the meteorite from Mars, how long it drifted through space, or whether researchers will attempt to narrow down the 13 candidate locations any further.

Description This global map of Mars shows 13 locations that match the mineralogy and chemistry of Teghaza 001, one of the most ancient Martian meteorites ever found on Earth. While scientists can never know for sure where a Martian meteorite originated, Teghaza 001 includes clues that link it to highlands in the southern hemisphere of […]
