Man in Outer Space Without a Special Space Suit

Problem statement: Many people dreamed about a living human in space without the encumbrance of a complex space suit. Unfortunately no scientific research and inventions: How to make it? Approach: Purpose of this research was to initial researching of this problem, necessary conditions, inventions, design needed devices, system and testing them. In this case main problem is how to satiate human blood with oxygen and delete carbonic acid gas (carbon dioxide). Proposed system enabled a person to function in outer space without a space suit and, for a long time, without food. Results: The theory showed that man can be in space without special complex and massive space suite, it is necessary special testing in animals. Current heart-lung apparatus allowed testing this idea. Researcher offered the simple light apparatus and system for astronauts. Conclusion: Biological humanity can only seriously attempt to colonize space if people will have simple apparatus for support their live in space without massive complex space suit. That is useful also in the Earth for sustaining working men in an otherwise deadly atmosphere laden with lethal particulates (in case of nuclear, chemical or biological war), in underground confined spaces without fresh air, under water or a top high mountains above a height that can sustain respiration.
