There's Liquid Water Deep Down on Mars
Mars once flowed with water—then 3 billion years ago, it mysteriously disappeared. Where did these ancient Martian seas go? Did the Red Planet's collapsing magnetosphere allow solar winds to strip away its water into space or did the water sink into the Martian regolith, hiding from our view?NASA’s InSight mission may have cracked the case. Seismic waves from meteorite impacts revealed water layer lurking 5.4-8 kilometres below the surface.
