ESA Targets ExoMars Rover at Oxia Planum's 300-Km Clay Deposits for Ancient Life Search

Summary
ESA said the Rosalind Franklin rover is now aiming to land at Mars' Oxia Planum, where scientists see clay-rich terrain as a prime place to preserve signs of ancient life.
A new study mapped clay deposits stretching about 300 kilometers from Oxia Planum to Mawrth Vallis, using ESA's Mars Express and NASA's Mars Reconnaissance Orbiter to trace mineral layers and shifts in ancient water chemistry.
Oxia Planum may once have hosted ocean-scale water or massive flooding about 4 billion years ago, making the site valuable for reconstructing early Martian climate as well as testing for biosignatures.
The rover, projected to launch in 2028, will pair with ESA's Trace Gas Orbiter and use a drill to probe below the surface, where preserved evidence of past life would be more likely to survive.
Mars' ancient ocean was far larger than imagined. Where does this discovery tell scientists to look for life next?
If the Rosalind Franklin rover finds life's building blocks, can it prove it's not just a geological false alarm?

Overview
The ExoMars Rosalind Franklin rover mission, set for launch in 2028 and landing in 2030, will explore Mars at Oxia Planum, a site chosen for its rich geological history. The mission’s main goal is to search for signs of past life by investigating whether Mars once hosted microbes within its buried clays. To do this, the rover will extract samples from the Martian subsurface, aiming to uncover answers about life beyond Earth. This ambitious project builds on international collaboration and advanced technology, offering a unique chance to deepen our understanding of Mars’s potential for habitability.
