Across the vast silence of planetary time, the European Space Agency's Mars Express orbiter has returned images that reframe what we thought we knew about our neighboring world. Three and a half billion years ago, Mars was not the barren, rust-colored desert of our imagination but a place convulsed by water — where groundwater burst from beneath the crust and carved a valley 1,300 kilometers long in what amounted to a geological instant. The discovery of Shalbatana Vallis, with its eroded craters, volcanic remnants, and collapsed terrain, invites us to reconsider not only Mars's past but the a
