Members of NASA’s Mars Exploration Program, the European Space Agency, the Australian Space Agency, and the Australian Commonwealth Scientific and Industrial Research Organization are in Western Australia’s Pilbara region to investigate “stromatolites,” the oldest confirmed fossilized lifeforms on Earth.
“This science expedition was a great opportunity for NASA to work with our international partners to study the ancient Earth as it relates to Mars, which may have had a similar past,” said Eric Ianson, director of NASA’s Mars Exploration Program at NASA Headquarters in Washington. “The more we learn about our planet’s evolution, the more we can apply that knowledge to our characterization of the Red Planet.
“What we’re looking at here in Western Australia are known as stromatolites,” said Mitch Schulte, program scientist for the Mars Perseverance Rover at NASA Headquarters. “They’re fossils caused by mats of microorganisms living around 3.5 billion years ago that had their presence captured and preserved in the rock record for all this time.”
