Ice lake found on the Red Planet
The existence of the water-ice patch on Mars raises the prospect that past or present life will one day be detected.

It also boosts the chances that manned missions could eventually be sent to the Red Planet - because they would probably need accessible water to survive.

The highly visible ice lake is sitting in a crater which is 35 km (23 miles) wide, with a maximum depth of about two km (1.2 miles).
