Right now the environment of space has a certain amount of mystery, even an aura of magic, connected with it. This is caused largely by its unknown elements. We have always been fearful of the unknown. Space is not hostile toward man. Hostility is willfully, deliberately directed by someone with the intellect and ability to act.
Space is simply there, following the immutable laws of nature that govern creation.
Neither is it hospitable. Just as there is danger for man on earth if he walks off a high cliff, stays out in the tropic sun too long when he is unaccustomed to it, or attempts to live in the arctic cold without adequate protection. But man reacts to his environment, and adjusts to it. He has learned to live on earth without undue danger. And he will live in the environment of space, as he comes to know its characteristics better, and learns to use them to his advantage.
