Joseph Green followed a duel career, working for 37 years in the American space program (six military, 31 civilian), and freelance writing at night and on weekends. He retired from NASA as Deputy Chief of the Education Office at the Kennedy Space Center.

At KSC he specialized in preparing fact sheets, brochures and other semi-technical publications for the general public, explaining complex scientific and engineering projects in terms understandable to a layman. He also prepared over 20 science papers for NASA and contractor executives.

As a part-time writer he produced five novels and about 90 short works, the latter published primarily in the magazines Analog and Fantasy & Science Fiction, and in original anthologies.

Prior jobs include working as a mill hand, construction worker, and shop supervisor for Boeing, the last while building Bomarc and Minuteman missile bases around the USA. His formal education includes a B.A. from the University of Alabama.
