Does Mars have water on it?

Answer 1

No because water freezes (and thaws) at zero degrees Celsius. Mars' winter temperature is something like -150 degrees C... It's summer is something around -25 C. Liquid water on the surface would simply freeze, and get covered with dust and rock and more dust. There is some question as to whether liquid water exists underground, where magma and the heat of the planet would keep it thawed. Discoveries of large amounts of methane in Mars' atmosphere point that Mars is geologically active, meaning its not a solid lump of rock and that it is possible that magma flows deep deep beneath the surface. (It could also mean that life exists but that's a little redundant)

Though evidence has found that liquid water existed on Mars's surface in the past.

Answer 2

No, the density of Mars is 3.9335 g/cm³ (the density of water is 1.00 g/cm3), therefore Mars would sink.

The planet that would float in water is the planet Saturn which has a density of 0.687 g/cm3.

Answer 3

Yes, Mars has frozen water in the form of ice at its polar caps and underground. There is also evidence of ancient rivers and lakes on the planet, suggesting Mars once had liquid water on its surface.

Answer 4

Water can't boil on Mars because its maximum temperature is 32 degrees F, which is the freezing point.

Answer 5

no there is not water on mars but NASA found out there used to be water flowing on mars

Answer 6

yes we can if you are less than 38 pounds

Edit: I don't think you can. The gravity is a lot more than the Moon.

Also there's no liquid water to float in.

Answer 7

yes it has water in it...

Answer 8

no
