document: Intelligent control of life support for space missions Future manned space operations will include a greater use of automation than we currently see . For example , semiautonomous robots and software agents will perform difficult tasks while operating unattended most of the time . As these automated agents become more prevalent , human contact with them will occur more often and become more routine , so designing these automated agents according to the principles of human-centered computing is important . We describe two cases of semiautonomous control software developed and fielded in test environments at the NASA Johnson Space Center . This software operated continuously at the JSC and interacted closely with humans for months at a time
