I don't think you'd need full earth graffiti to minimise the negative health effects of microgravity. Probably half or so would be enough. Just make sure people

  Low gravity will always have health effects. If you plan on returning to the Earth and have a very short stay, 0.5 G is probably a massive improvement over 1 G, especially if you keep doing exercise. For a martian transfer, you'd acutally only need 0.38 G as they'll be losing their bone structure to Martian gravity either way. Funny thing actually, a person born on Mars could probably never walk on the Earth without years of intensive physiotherapy.
