Is a 70mm refractor telescope strong enough to see planets like venus and mars?

Perhaps 10% of the amount Earth has, mostly far below the surface of Mars. Earth has considerable water in the crust and mantel, but steam keeps pushing it toward the surface. Most of the interior of Mars is not hot enough to make steam under the high pressure conditions.

It all depends on who you ask ... and on if that person is looking through rose-colored glasses. NASA wants to see water. So they see it everywhere -- moon, Mars, Mercury, Pluto, Ceres, and almost every moon of Jupiter and Saturn.

The reality is that there is no confirmation of any of that water. There is ice on Mars. And in certain areas, that ice can sublime to a vapor and back to ice as the temperature rises in summer (and falls at night and in winter).

"On September 28, 2015, NASA announced that they had found conclusive evidence of hydrated brine flows on recurring slope lineae, based on spectrometer readings of the darkened areas of slopes. These observations provided confirmation of earlier hypotheses based on timing of formation and rate of growth that these dark streaks resulted from water flowing in the very shallow subsurface. The streaks contain hydrated salts, perchlorates, which have water molecules in their crystal structure.

The streaks flow downhill in Martian summer, when the temperature is above –23 degrees Celsius, and freeze at lower temperatures." That is a quote from here :-- https://en.wikipedia.org/wiki/Mars#Hydro... and that is hardly an ocean of water.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
