The history of water on Mars has huge implications for the possibility of life on Mars and the future of life on Earth. This is the first of two lectures on this subject, with the second lecture to be given by Steve Clifford in February

Widespread fluvial dissection of the heavily cratered martian highlands indicates that, around 3.8 billion years ago, Mars had a warm, wet, Earth-like hydrologic system with precipitation, rivers, lakes and oceans. Mars then cooled and developed a kilometers-thick permafrost. Around 3.0-3.4 billion years ago massive eruptions of groundwater trapped beneath the permafrost caused huge floods that flowed into the low-lying northern plains to create an ocean that rapidly froze. The water subsequently sublimated away, some to form the present polar caps but most being lost to space, mainly during periods of high obliquity.
