Advanced life support systems require computer controls which deliver a high degree of reliability and autonomy and meet life support criteria. Such control systems must allow crewmembers on long-term missions to perform their scientific and engineering duties while minimizing interactions with life support systems. Control systems must be the “brains” of life support systems providing air, water, edible biomass, and recycling services. They must establish and maintain life support components in an optimized manner, providing self-sufficient infrastructures independent of Earth-based resupply.The CELSS (Controlled Ecological Life Support System) Breadboard Project has implemented such a computerized component of a future mission. The Universal Networked Data Acquisition and Control Engine (UNDACE) is the software interface between humans and hardware controlling plant growth experiments.
