No we won't. Neither of us will live to see it. Mars can only be inhabited by going underground. It will never be terraformed.

Us living to see it's completion is irrelevant. Chances are in my lifetime, since we will be sending Humans to Mars, some of the earliest efforts will be to deduce whether the planet is actually suitable for terraforming and implementing initial stages. At present most signs point to yes, other than the magnetic field issue, which in itself is extremely overrated as a problem. Earlier in Earth's history there were much higher levels of radiation on our planet in addition to other conditions hostile to life and... somehow... that also happens to be the time period when life actually began to appear.

If we can build a nuclear rocket to go fast enough we can travel thousands of years into the future to see if Mars has been terraformed.

Finally. A good use for the Twin Paradox.

Fear of nuclear power is the only thing that is holding back the space program. Tax payers object to the space program because it is too expensive but with nuclear power space travel would be cheap.

We are now starting to find habitable planets in interstellar space but the environmentalists don't want us to go because we would have to use nuclear power to get there.

The amount of rocket fuel needed to get somewhere, whether chemical, nuclear, or antimatter, is proportional to the square of the distance traveled because it needs to carry its fuel wherever it goes. A better solution is an electric engine, perhaps similar to an ion engine. I have an idea for a relatively inexpensive way to travel to other planets; I'll post it on my blog once I've written a good description of it.

I'll move to the colony on another planet as soon as it has internet connection and cable.

Forget about it. Mars can be as many as 20 light minutes from Earth.

Internet works on our planet because no two points are more than 1/10 of a light second apart.

Someday there will be an interplanetary information network. Its impossible to get around the light barrier (afawk) but data exchange between Earth and Mars is an inevitability.

If one does not mind a 40 minute round trip (at times). It makes conversation a bit difficult.

Of course. It will be akin to an extremely slow instant messaging service I suppose

Then I shall move when they set up the interplanetary information network! :lol:

How about impossible. No magnetic field, no life except deep underground.

ruveyn

Actually it wouldn't be that deep. The lowest point on mars is in the Hellas Impact Crater and is about 8200 meters below the Mars Areoid (a reference height similar to Earth's sea level).

But if you look closely you'll notice that the area around the crater is about 200 meters above the areoid. Add a few hundred meters for safety from even bigger craters, and you still only have to drill about 30000 feet (or 9144 meters) underground: Quite possible considering we drilled over 40000 feet in the Kola Superdeep Borehole in Russia.

Or maybe more like writing letters to each other. People were so much more patient back then...

I could only imagine the pressure that deep, would planetary life even be possible. moving water through a semipermeable wall seems like insanity at that gravitational level, or the chemicals in our body being able to travel. Seems crazy to me.

I wonder what it would be like to travel thousands of years into the future. Would marriage be obsolete? Would everyone practice free love like in the movie Brave New World? Would children be hatched in incubators ? Would we be considered savages compared to their advanced civilization?

Definitely not. We will be far less intelligent in the future than we are now, just like people thousands of years ago were more intelligent than we are. Sure, maybe we have more knowledge and have invented more things we can use, but as far as thinking power goes people get dumber over time. It's social entropy: Order descends into chaos.
