NASA scientists traveled to the Scottish Highlands to examine ancient rock formations matching Martian environments, building on rover data that points to potential ancient microbial life.
Holding evidence of microbial life dating back 1.2 billion years, researchers with the Goddard Instrument Field Team focused their recent work on the Stoer formation, a coastal site featuring cliffs and rocks laid down in ancient river and lake settings. This geological setting mirrors the layered mudstones and siltstones rich in clay minerals found on Mars. The Scottish rocks predate the emergence of land plants on Earth.
Timing Coastal Climbs Along Clachtoll
Field investigators had to carefully time their climbs to access investigation sites between high tides, ensuring they retreated before slopes became slick in the damp Scottish climate. Carrying science instruments on their backs, team members hiked the rugged coastline of the Clachtoll region. Using handheld gear, scientists checked mineral and chemical compositions directly on the spot, searched the terrain for environmental indicators, and gathered samples for laboratory study.
The expedition was inspired by discoveries from the Perseverance rover, which identified reduction spots—telltale chemical reaction markers that could suggest ancient microbial activity—inside Jezero Crater on Mars.
Partnerships Powering the Scottish Expedition
Teams across the United States and overseas are now processing the collected material with advanced laboratory tools. While the Goddard Instrument Field Team led the field deployment out of the agency’s Goddard Space Flight Center in Greenbelt, Maryland, the project drew support from a large academic and institutional network.

Previous Planetary Research in Scotland
A team from the University of St Andrews previously tested technology slated for Martian life detection at Lower Diabaig in Torridon. That area features billion-year-old rock formations comparable to those on the Red Planet. Scotland’s ancient geology has a history of serving as a terrestrial testing ground for planetary research.
Other Martian sites carry names such as Siccar Point, Muck, Wick, Sandwick, and Holyrood. The connection between Scottish geography and Mars extends directly into official mission mapping. NASA selected the name Torridon for a Martian geological feature because of the Torridonian Supergroup in the northwest Highlands, which houses some of the oldest evidence of life preserved in UK rocks. In 2012, the Highland community of Glenelg celebrated an official Martian location being named after the local area.
