The rovers have gone to Mars, but why not people?

Better question would be, why would anyone go to Mars since it would be so dangerous and expensive to do so?

Because no one with the resources to get to Mars (i.e., world governments) have had a desire, and understandably so.
The Outer Space Treaty of 1967 forbids governments from claiming land on celestial bodies like Mars, so the governments don't have an interior motive for putting people in different places in our universe.
The public hasn't put any political pressure to put people on Mars, so the governments don't have much of an exterior motive either.
The situation is changing though... Countries like China are really pushing space exploration, which in turn presses other governments to act. Also, since the circumstances surrounding the Outer Space Treaty are no longer, some organizations are pressuring for a change to allow ownership of extra-terrestrial land, which would increase interest in establishing a human presence on Mars and elsewhere.

The biggest reason is that it would take a LONG time to get there. I've heard estimates of several years of straight travel time one way. It would take a ton of fuel and provisions to sustain a human crew for that length of time, let alone keeping them alive once they (hopefully) reached the planet. Some people have floated (no pun intended) of having a moon base be a staging point for launching shuttles to Mars. Others have thought of using the international space station. But either one of these isn't really all that much closer to Mars than a launch from Earth would be.

ah well - It takes an incredible amount of weight to send a small package. there are also considerations of bone density loss and plain mental issues. If an incremaental approach is taken it will be done but it will not be a trip it will be closer to a migration. The people who return(and some will stay) will not be the same people who left. If you want to see what it will be like look at the conquest of america by european and substract the wars. It will need a change in basic thinking (A paradigm shift) to properly project the future

I did go to mars if you can find a video I made title "True Space Travellers and Mars Exploration" if you do find it send me a email.

It's because of the climate. We can't live on mars becasue it is too close to the sun, I assume that it would fry our skin no matter what kind of protection we had on. And it takes a really long time just to make it to the moon, I think it takes like a month--maybe I'm wrong--but to think, traveling to mars?

1. There are no direct flights from Earth.
2. No motels.
3. No restaurants.
4. No entertainment.

Obviously needs more research to minimize the risks .... and also is a very long trip, meaning the muscles deteriorate quite a lot, until the crew is there .... and when then undergoing gravity no doctor is available there

Because the journey would probably take 3 years one way. They would not have enough food, fuel, oxygen, etc. and a lot could go wrong in that length of time. Then there's the journey home...
It will probably never be possible.

It is very far away from earth and in the fastest space shuttle it will take three years to get there. The human body can not survive in the weightless condition upto three years.
Enjoy....
