This annual contest, co-sponsored by NASA Ames and the National Space Society, is for 6-12th graders (11-18 years old) from anywhere in the world. Individuals, small teams of two to six, and large teams of seven or more (often whole classrooms with teacher leadership) may enter their design for and description of a human colony in outer space. Submissions must relate to orbital settlements; they may not be on a planet or moon. Settlements must be permanent, relatively self-sufficient homes, not temporary work camps. Designs, original research, essays, stories, models, artwork or any other orbital space settlement related materials may be submitted. Grades 6-8, 9-10 and 11-12 are judged separately, except for the grand prize. The single highest scoring team or individual attending will receive the NSS Bruce M. Clark, Jr. Memorial Space Settlement Award for $3,000. Submissions must be received by March 15.
