Colony on Mars?

I don't believe there are glaciers on mars, none have ever been identified. From what I have read, the little robots humans have sent there uncovered a white substance which soon disappeared and scientists think it may be water that evaporated.

Mars is very Earth-like in many ways. First, it is a rocky planet with an iron-nickel core much like Earth's, with a silicate mantle and crust. There are probably no tectonic movements as on Earth, so the geological features are more enduring and stable. The entire planet seems to be more or less uniformly coated in a thick layer of dust. The dust has the same composition all over the planet and is composed of fine-ground basalt (sort of like talc.)

There are two principal topographies on Mars. In the north, about 1/3 of the planet is a smooth and flat basalt plain, with few craters or major geological features. The southern 2/3 of the planet is highlands, very heavily cratered and full of extremes in altitude and terrain. All over the planet there are signs of water, and in fact in days gone by there was an ocean, or large lakes. Layered sandstones and different minerals attest to the presence of liquid water. There are even signs of great flood events similar to Lake Missoula in the northwestern U.S.

I think you mean that Mars has geological features that indicate water erosion, but that water dried up a very long time ago.

Predominant surface minerals include olivine, pyroxines, and feldspars, the same minerals so common in Earth's crust.

When I was a kid we were still talking about the Canals on Mars. Today we have a complete and highly detailed map of the planet, good knowledge of its geological history and composition, and have found water.

Water is present in more than sufficient quantity to make small colonies possible. I have no idea why anyone would want to live there. The exploring robots have found no traces of a Walmart or MacDonald's.

I'd like see some evidence of these large quantities of water. As far as I know, only small traces of what is speculated to be water have been identified.

The Panspermia Theory rings true.
In the science program, "Magnetic Storm", highlighted is how a planet's molten core affects it's atmosphere, and protection from harmful cosmic solar rays from the Sun.

Discussed is how, over the last 300 years, also, the Earth's magnetic core has been diminishing in intensity, and how through various strata and magma study about past changes, that when the magnetic intensity is at it's weakest, a magnetic pole shift occurs.

The statement made also, that it is not "if" it will occur on Earth, but, "when".


It is speculated that the cooling of the molten core led to the dissipation of Mar's atmosphere.

•Rock is believed to be the oldest recognised sample of soil from Mars and holds a wealth of information about its origin and age

•Also provides clues about the release of volatiles - chemicals linked to a planet's water - and the first 100 million years of the planet's existence


"The zircons in the meteorite were probably formed by re-melting of the original Martian crust, says Professor Munir Humayan. Their similarity with the earliest terrestrial and lunar zircons suggests Mars' crust formed at the same time as Earth and Moon."

So... a gift? Where the hey did this come from? Rock suddenly appears at the foot of the Rover on Mars?

As the article says, the most likely explanation is that it was disturbed by the Rover's wheels.

No need to think of green men. Besides which, they could find better ways to contact us than secretively placing a rock in front of one of our robots. Why not wave into camera instead, or hold up a sign saying "Hello Mum!" ?

There is "Panspermia", the theory of Life being seeded here from Mars.
Then there's, "Transpermia", about Earth microbes transferred to other planets from past impacts here.

Think you made an assumption as to what I was referring to.
?
Besides, when have - "they" - ever stood in front of a camera and waved?
But, thanks for posting.

They haven't. That's my point,
