Spacing Out in the Final Frontier

Ever since way back when, mankind has looked at the heavens and wondered what's up there, and some had notions of actually going there. In the 20th century and extending into nowadays, progress has been significant. While space probes are impressive in their own right, having men land on the moon and operate space stations is foudroyant. I reckon it's human nature to want to go further.

Mind you, Earth can be considered a mighty large spacecraft itself. It was put here by the Creator for a reason, and we were designed to live on it. Significant difficulties exist for protracted space flight, such as collisions with objects, radiation, and other things. Two worth highlighting are the psychological difficulties and the physical problems of being without gravity.
Through the imagination, we can soar through distant galaxies. Sooner or later, physical reality hits home.

Amazing, isn’t it, that space travelers in the movies can walk normally and breathe the air no matter what planet they land on. It may save money for Hollywood, but is it realistic? A couple of articles suggest otherwise. For better or worse, we humans are stuck here.
