ExoMars / Rosalind Franklin Rover

European Mars rover mission to search for biosignatures. Originally a joint ESA-Roscosmos mission, restructured after Russia's invasion of Ukraine in 2022. ESA partnered with NASA for landing system support. The Rosalind Franklin rover can drill 2 meters below the Martian surface — deeper than any other Mars mission — to search for organic molecules shielded from radiation.
