It doesn't matter how fast you are moving, you still would not notice any difference, at least not according to your own clocks moving with you on Mars. You need to be able to observe the clocks on earth while you are located on Mars (or after returning from Mars) in order to see a difference. Then it is simply a matter of clock accuracy as to whether or not you will be able to 'notice any difference'.

In the previous discussion of time dilation, Kaptain K and I, for example, were making an implicit assumption (required by SR & GR) that one is able to observe & compare clocks in two different frames.
