There are systems being thought about to help Martian Humans like exo-suits that would use nano robotics to help Martians cope on earth. This is feasible of course and likely the way it will be done but new questions pop up like what happens when they need to go to the loo?!
In other space related news, was reading his article with interest as it's a topic that's often talked about and finally two models by experts have been drawn up that could in theory work to make use of wormholes. Obviously only one of these slows for the possibility of humans to travel but as always time is relative and you simply cannot loophole around this. Whilst the person travelling through would be able to get from a point in the galaxy to another instantly, the people back on Earth would have to sit through the thousands of years as relative observers. This type of travel would effectively be a one way journey.
Maybe in time this could be the way humans continue existing, once our solar system is nearing its end, hope through and find home elsewhere or send human seedlings and resources through that are looked after by AI and robots during icubation and once ready, slowly grow with the ship carrying a historical record so they know what's been going on. A bit like the recent movie "Mother".

An interesting point made on reddit too:
It would be possible the group going through end up meeting humans on the other side, that are technically so advanced they found a quicker method of transportation
