Spacer Community

Quote: "Most who grow up on an orbital habitat or asteroid belt community live a life much like anyone else in a high-tech city. For these people, their homes might as well be planetside, other than the slim chance of a life-support failure or similar disaster. However, not all space habitats are like this. Some are collections of small settlements in a planetoid field, with shuttles plying between them. For the inhabitants of such a community, formal education is likely to take second place to rule-of-thumb instruction in how to survive and get a day’s work done in a spacer environment.
Some Travellers leave the community and seek a normal career elsewhere, but many hang around for a few years, picking up skills that might make them invaluable to a small merchant ship or similar employer where competence is more important than documentation.
‘Graduates’ of a spacer community have had instruction from skilled people, whilst ‘honors graduates’ come out with additional skills which may have been gained at the cost of harrowing experiences."
