This is what Hauser said to Douglas Quaid in the famous 1990 movie Total Recall. It is now the year 2011 (soon to be 2012) and you would think that travel to Mars would be readily available to the public by now. However, as far as I know, a person can't book a trip no matter how much money he/she has.
While the public can't visit Mars physically, one can do so virtually through the High Resolution Imaging Science Experiment at the University of Arizona. The above image is just one of many that can be viewed at the HRISE site.
