Traces of recent water on Mars: Liquid water on Mars as recently as 200,000 years ago

New research has shown that there was liquid water on Mars as recently as 200,000 years ago. The southern hemisphere of Mars is home to a crater that contains very well-preserved gullies and debris flow deposits. The geomorphological attributes of these landforms provide evidence that they were formed by the action of liquid water in geologically recent time.
