This answer and the linked YouTube video discuss some difficulties with the experience of artificial "gravity" generated by small rotating craft (like one that could be launched to Mars in the near future). The gravity gradient from head to foot and especially the Coriolis effect would be quite strong for a small craft, and could conceivably be more uncomfortable than no gravity.
note: One could use an external mass and tether for a more uniform artificial gravity, but that's a separate issue.
After a flight to Mars with no artificial gravity, what would the initial experience be like after landing? With no ground crew to assist, would the crew simply sit there for a while, then slowly start moving and assisting each other? Would robotic assistance be particularly helpful in this case? I can imagine without a ground crew, I'd appreciate some help from a robotic arm, bringing me things I ask for, helping me stand, and possibly get out of my bulky suit.
Would Mars' lower gravity compared to earth reduce the risk of breaking a bone (considering the bone loss associated with the trip) or would that still be a major concern?
This is a prototype of the robotic arc welder that will tack-weld the F9 legs down after landing at sea. (humor) A similar device could assist the astronauts, but at lower voltage.
