Images from the [spacecraft][3] orbiting [Mars][4] seem to indicate the [Red Planet][5] may once have had oceans and lakes, and researchers are still trying to figure out how these bodies of water could have developed. A new explanation is that underground aquifers fed water to the surface, forming the floors of ancient [continental][6]-scale basins on Mars. The groundwater emerged through extensive and widespread fractures, leading to the formation of river systems, large-scale regional [erosion][7], sedimentary deposition and water ponding in widespread and long-lasting bodies of water in Mars northern plains.
