The main reason is that Mars is a very unhealthy place, not just for humans but for all life. Forget the temperature extremes. The biggest problem with Mars for maintaining life is that it has almost no protection against radiation. It has no iron core like Earth and thus it does not have the magnetic field that protects humans from cosmic rays and solar mass ejections.
Read this article for more information.
Six feet of soil can shield against cosmic rays as can a few centimeters of water. Since hauling water to Mars hardly seems practical, unless an ample water supply is found on Mars, the "explorers" will have to be satisfied with living and exploring under the surface.
Also, the human body is so adapted to our level of gravity that almost absent gravity (as in the space station) damages bone density. In a large space craft that rotates, you can use centrifugal force to simulate gravity, but how do you do that on the surface of Mars? Not exactly a vacation and no place anyone would want to live for long.
Terraforming isn't practical unless there's a way to give the planet a magnetic field. Otherwise, the atmosphere will simply be lost to space.
What do you think?
Apparently that passage was one of the warped ones, as scientists currently believe strongly enough that they exist, that they have a number of "tachyon traps" in place in an attempt to detect them - a lot of effort for a myth.
For now, it remains highly dubious.
At minimum, it's a three-minute light-speed trip to Mars!
You would not have infinite mass at the speed of light; mass is an amount of matter. You would not have infinite weight, either, since weight is a function of acceleration. Given a gradual acceleration, we could stop accelerating at light-speed while continuing to move at that speed and float around the same as astronauts orbiting the earth.
Robert D - I don't know the source of your information, but I learned that as an object accelerates, it's mass increases, until, at the speed of light, it becomes infinite.
Mass, measured in [kilo]grams, with an applied gravitational force (acceleration) is weight, measured in Newtons. You're thinking of casual weighing, measured in kilograms. The space shuttle has the same mass while in its hanger on earth, when in space, and also when it is achieving escape velocity..
it might be simpler to bring Mars to you.
NONONONONONONO!!!!! think about the impact on the tides!
"The tides come in, the tides go out - you can't explain that --"
I don't even CARE if life exists on Mars, unless it is intelligent life, and I wonder if it's worth not doing all the good that investment would purchase just to find out that, yeah, 55,000 feet down we found a bacterium. I'd use the money to contribute to balancing the budget and providing universal health care before I'd spend money on finding life on Mars, or anywhere.
To me the odds of some other life forms, in no way similar to us, existing among the billions of galaxies is a good one. I can't imagine our planet among trillions is the only one inhabited by a life form.
Any such lifeforms would have evolved, based on the specific gravity of their planet.

I can go on, Nostradamus, but your whole line of argument is weak shit.
I was wrong about where I misplaced my glasses this morning, so I guess that means we should start mounting a trip to the edge of the universe, expecting that someone will figure out the details later.
