Exoskeleton for Astronauts to Mars, Probably Good Idea

After so long in space to arrive at Mars an exoskeleton support system might be a life-line for the astronauts. Mars might feel more like Jupiter after time in space. NASA and SpaceX probably considered this already but there’s no harm in pointing it out again. I think that there is a higher probability of life under the surface of Titan (one of Saturn’s moons) than any on Mars. Unless they are intending to use Mars as a landing station for Titan as, obviously, Titan is much further away. By exoskeleton, I mean robotic assistance to aid muscular movement as well as the already well established environmental space suit.
