The largest known crater on the planet is the Vredefort Crater in the Free State Province, South Africa. It is a couple hundred kilometres across and is one of the only large meteorite impact craters that one can see exceptional detail into the geological composition of craters. The crater has a diameter of roughly 250 - 300 km.
But it is important to note that there is a chance that there is a larger one in Antarctica as scientific research there suggest a 'possible' one, but studies have not confirmed this yet.
The robots sent to Mars have found Water Ice in large quantities on the surface of Mars.
Jarosite is the sulfate mineral found on the surface of Mars that indicates the past presence of liquid water.
We have not found a good reason that some sort of living thing could not live on Mars. There is water, and the surface of Mars is certainly warm enough. But, no living things have been detected yet on Mars by the several rovers that we have sent to Mars' surface.
Mars is sandy.
The surface area of planet Mars is 144,798,500 km2
there is frozen water on mars some where under its surface
There are many places to find the facts about Mars's surface. These facts can be found online and in the local library.

Mars has a variety of surface features, including vast deserts, rocky mountain ranges, ancient river valleys, and polar ice caps. The surface is largely composed of iron-rich basaltic rocks and fine-grained dust. The planet also has the tallest volcano and the deepest canyon in the solar system.
The deepest valley in the solar system is Valles Marineris and is located on Mars.
The percent of water that is found on Mars is only 2 percent. The surface of Mars is mainly dry which is marked by old volcanoes.

We have discovered evidence of water beneath the surface of Mars. We have also found that there was once water on the Martian surface, though it is now gone.
Mars has roughly 30% the surface area of earth. All of that is dry ground. We have only found(very little) ice on mars.
Here are some major differences:Mars has two moons (Phobos and Deimos) while Earth has one (the Moon).Earth has an atmosphere breathable by humans; Mars does not. (The atmosphere on Mars is almost all carbon dioxide.)Earth has higher gravity than Mars.The deepest canyon on Mars (Valles Marineris) is 4 times as deep and ten times as long as the deepest canyon on Earth (Grand Canyon).Mars has a year of 687 Earth-days.The surface temperature of Mars is much, much colder. Earth is about 57 degrees (F) compared to -87 degrees (F) on Mars.
