Description:
NASA-Johnson's RLSS testbed employs higher plants in a closed environment, in conjunction with a physicochemically-based life-support system, to create an integrated, biological/physicochemical RLSS. Crew presence is simulated by a human metabolic simulator, and operation is sufficiently automated for crops to be grown from seed to harvest without human intervention. Attention is given to the Variable Pressure Growth Chamber, which will be operable at both ambient atmospheric pressures and at the reduced pressures representative of operations in lunar and Martian environments.
