Ok, you can survive 437.7 days in microgravity. You do realize they have to land on Mars and it has gravity. They will be in no shape to land or do anything after that long without having been in a gravity environment along the way. The other problem is lets suppose they use water. Water isn't exactly light and for the same amount of protection, you will probably have to put up 15 times as much water as lead making the vehicle even bigger. Also, your estimate that the vehicle would be 50 tons is ridiculous. Anything with rotating sections, a large radiation shield, and the fuel alone is going many times heavier (probably on the order of 1,000 tons). It is a simple fact this is all purely science fiction and nobody will go to Mars in our lifetimes.
