    No! You're missing the point of relativity completely. Yes, the ship should look contracted to Hussbot. But the reverse is also true: the environment looks contracted from the ship! That's the entire point of relativity: none of the systems are better than the other - both are inertial frames. The rules of nature should be the same in any inertial frame. That's one of the two basic assumptions special relativity is built on. It may seem paradoxical, but in fact it's all consistent (but you have to give up on the idea of simultaneity).

    The reason the twin paradox is still true, is that in order to return to Earth, the twin in the spaceship will have to accelerate - his system is no longer an inertial frame; you can distinguish between the two systems.
