The science and technology which have advanced man safely into space have brought about startling medical advances for man on earth. Out of space research have come new knowledge, techniques and instruments which have enabled some bedridden invalids to walk, the totally deaf to hear, the voiceless to talk, and, in the foreseeable future, may even make it possible for the blind to "see."

Space is an environment of emptiness. It offers no possibility for natural adaptation to any living organism - and particularly not to the highly sophisticated creature, man. Yet man has the ability to resolve this paradox through his intellectual power and creative faculties.

If someday rockets should open the gates to space, then we must be oriented as to its environmental conditions and their possible biological effects. To study this, and to find means of protection, is one of the tasks of space medicine.

The conquest of the outskirts of the atmosphere, and eventually space, is a revolutionary event, comparable only to the transition of the aquatic animals to the land in geologic times.

It is not too farfetched that soon it will be possible for a physician to send the electrocardiogram and the heart sound via communication satellite to a distant heart specialist for diagnosis and consultation.
