Vacuum Adapted Humans

Homo cosmosapiens spatialis and other subspecies.

In the late Interplanetary Age, after the development of the original Space Adapted Humans, further developments in genetics led to further projects aimed at adapting humans to vacuum. The end result was a gradual convergence of the various solutions, resulting in the Deepspacers, also known as the Vacuum Adapted Human clade. The name is a misnomer, because the classic unaugmented VAH can only survive in a hard vacuum for brief periods of time. Nevertheless they are more suited to survive in instances of ship or hab explosive decompression, low oxygen, and so on, until help arrives or the problem can be fixed.

As with the original microgravity adapts Homo Cosmoi, the new clade of spacers soon migrated outwards, finding ready employment among the megacorps keen to develop the outer solar system, the Kuiper belt and the Oort cloud. Like many deep space migrating clades of the time they were only mildly effected by the nanodisaster - in fact the result of the nanodisaster was to drive them deeper into interstellar space.

In the 1000's some VAHs joined the Federation, but most preferred to stay aloof or colonise interstellar space on their own. They often supplemented their biological adaptations with tailor made bionano and hylonano augments. Over the centuries the spacers have developed into an independent branch of humanity, living together with baseline and near-baseline humans in some habitats but always a bit apart due to their easy access to space. Many spacer-only habitats exist.

VAH Spacers have a skin covered with enamel scales, feet with opposable thumbs, eyes covered with resilient lenses and a flexible membrane that when in space seals the nose and mouth. Considerable quantities of oxygen are stored in the blood and tissues of the Spacers and slowly released while they are in vacuum; a similar augmentation to the deep-sea diving abilities of the Merpeople. Their thick skin can function as a pressure suit when necessary.

Later clades derived from humans and other species, such as the Sailors, were developed which could survive in vacuum for an almost indefinite period.
