NASA map identifies 13 potential source sites for ancient Martian meteorite Teghaza 001

Partly verified · 4/5 supported1 cited · 1 min read

nasa.gov reports that the map shows 13 locations on Mars that match the mineralogy and chemistry of the meteorite Teghaza 001 . nasa.gov reports that Teghaza 001 is one of the most ancient Martian meteorites ever found on Earth . nasa.gov reports that scientists cannot definitively determine the meteorite’s origin, but clues link it to highlands in Mars’ southern hemisphere . nasa.gov reports that the base map uses data from the Mars Orbiter Laser Altimeter on the Mars Global Surveyor mission, and the identified areas were derived using data from the Mars Reconnaissance Orbiter .

Why it matters. Scientists now have 13 candidate locations on Mars that match the meteorite’s mineralogy and chemistry .
