title: Progress in European CELSS activities.
abstract: The European CELSS activities started in the late 1970's with system analysis and feasibility studies of Biological Life Support Systems (BLSS). Since then the European efforts have continued in two major directions: as a series of individual development tasks like the Environmental Life Support System and the Solar Plant Growth Facility, and in parallel hereto as overall coordination and planning activities for life support system long term needs definition and payload definition for COLUMBUS utilization. The early initiations for CELSS came from the industry side in Europe, but since then planning and hardware feasibility analyses have been initiated also from customer/agency side. Despite this, it is still to early to state that a "CELSS-programme" as a "concerted" effort has been agreed upon in Europe. However, the general CELSS objectives have been accepted as planning and possible development goals for the European effort for manned space activities, and as experimental planning topics in the life sciences community for the next decades.
