Seega otsustasid teadlased uurida maa-alust! Nad kasutasid Mars Expressi spetsiaalset MARSIS-seadet (<b>M<\/b>ars <b>A<\/b>t\u00e4iustatud <b>R<\/b>adar jaoks <b>S<\/b>pinnal\u00e4hedane ja <b>I<\/b>onosf\u00e4\u00e4r <b>S<\/b>(maapinna l\u00e4bistav) seade.

Nende kihiliste setete all avastati eriti heleda radarpeegeldusega ala, mille laius on 20 km.
