Water on WorldsEdit
- Mercury/Water - Water ice is thought to be frozen in Mercury's eternal shadow craters like the Moon. Smooth areas detected by Earth-based radar are an early evidence. Messenger found that the shadow craters are sufficiently deep to trap water ice there.
- Mars/Water - Life giving substance generally found today on Mars in the form of ice at its caps and as vapor in the sky. Large amounts of it could be stored underground in areas outside the polar regions, such as under the craters at Sinus Sabaeus. Salty water, which has a lower freezing temperature, could occasionally flow on the surface today. Parts of Mars' interior may be warm enough to allow liquid water to exist. It may come up in a mud volcano. Nasa's current mantra is "follow the water", which its spacecraft do to try to find evidence of past and present habitability.
