By now my picture of the Humans in this Universe is coming together nicely. The Spacers appear to turn out as some kind of hybrid between massai warriors, superstitious scientists and hacker pilots.

You notice that contrary to the spaceress in the earlier picture, this one has long hair. General tradition among Spacers is that prior to their first free-fall and completion of their checkout flight after training to be a cosmonaut they are not allowed to receive any tattoos, and are not allowed to cut their hair. Consequently, male and female spacers alike before the age of between 16 and 20 depending on their origins tend to have long manes. Some tribes, families and societies decorate and tend to their hair in ritualized fashion, others simply keep it as it is.

First free-fall is the first orbital flight that a young spacer takes in a crew position aboard a spaceship. Suborbital and Passenger flights do not count. A complete orbit or passage (if no body to orbit exists) is necessary. Usually, this achievement is accompanied by a coming of age ceremony and festivities aboard the ship.

Most young spacers complete their first free-fall along with getting their checkout: this is what the successful completion of spaceboard basic training is called. Once the checkout is finished, and the Student has passed, they are elevated to Adulthood and have their hair cut. The festivities above are usually split into two parts, the ritual part of which ends with the cutting and shaving of the hair of the head. After that, the feast and nonformal part of the party begins.

Young spacers are also not allowed to tattoo their bodies. Children can often be seen with sticker-tattoos when at play, however, the tattoos are a visible record of a spacers achievements and are thus treated as a legal document. Tribe, Profession, Age, Criminal record, Achievements and Family ties can all be deciphered from these tattoos. Young children only receive their Tribal insignia prior to completing checkout and first free-fall.

The girl pictured above is wearing an MCP (Mechanical CounterPressure: http://en.wikipedia.org/wiki/Space_activity_suit) Space Survival suit: the lack of helmet collar and absence of native fluid and climate system connectors identifies it as a training suit. Her right arm is a bionic prosthesis. Behind her ear the plug-connector for the spine-tape can be seen. This device is the topmost part of the neural interface implanted along the spine at around age 16, and serves as an emergency connector to the nervous system in case of mechanical disruption of the primary biological brain-limb interface (crushed or broken spine).
The spine-tape has access points along the back of the body, which serve to control exoskeletal suit elements or link into spaceship systems.

She is also barefoot, probably because she is lazy. Damn kids these days, can't even take zero grav training serious. You know, back in my day....
