According to NASA News Releases, a global map of Mars displays 13 sites that share the mineralogy and chemistry of Teghaza 001, which is noted as one of the oldest Martian meteorites discovered on Earth. Although scientists cannot definitively determine the origin of a Martian meteorite, Teghaza 001 contains indicators suggesting a connection to the highlands situated in the southern hemisphere of Mars.

The base map used in this visualization was generated utilizing data from the Mars Orbiter Laser Altimeter instrument, which is part of NASA’s Mars Global Surveyor mission. Researchers employed data from NASA’s Mars Reconnaissance Orbiter to pinpoint areas on the map, which are marked with white circles, that exhibit mineralogy and chemistry similar to those found in Teghaza 001.
