title: A life support system for satellite experiments over one year.
abstract: The study of organisms in satellites over a period of a year or longer has failed due, primarily, to the high technical efforts in order to keep even low organisms alive. A new life support system is reported which enables the performance of experiments over a long period of time with an approximate animal (Hirudo medicinalis). The system has a total weight of 3 kg and a current consumption of 4 watts.
