Briefings

A 2026 NASA photojournalism map identifies 13 specific locations on Mars matching the mineralogy of the ancient meteorite Teghaza 001, suggesting a southern hemisphere origin. The map uses data from the Mars Global Surveyor's Laser Altimeter and was updated using Mars Reconnaissance Orbiter data to highlight white-circled areas of interest.

Key points

• The map displays 13 distinct locations on Mars that share the same mineralogy and chemistry as the ancient meteorite Teghaza 001.
• Scientists identified these areas using data from the Mars Reconnaissance Orbiter, with specific locations marked by white circles on the map.

Context

Teghaza 001 is one of the oldest Martian meteorites ever recovered, and this map helps locate its potential source in the planet's southern highlands.

Limitations

The map is a snapshot from October 2026 and does not confirm the meteorite's origin; scientists cannot be certain of the exact source location.
