For future long-duration space exploration missions, NASA expressed the need for plant systems that may provide a nutrient dense supplement to crew diet and possibly other life support functions, such as CO2 removal, O2 production, water recovery, and waste recycling. Current and future infrastructure for plant growth include chambers with controlled environments. To ensure optimal growing conditions in these chambers, the plants will require precise monitoring of health throughout the plant life cycle. These monitoring systems will need to operate autonomously with little crew involvement. Current plant monitoring instruments include multispectral and hyperspectral sensing that require post-process algorithms to detect physiological phenomena. In Phase I, Space Lab Technologies (Space Lab) and the Space Plants Lab at the University of Florida (UF) investigated an improved approach for monitoring space plant health using a smart spectral polarimetric (SSP) imager to monitor morphological features and stresses. The Phase II work builds upon the prototypes and analyses completed in Phase I, which includes a deliverable of an engineering demonstration unit (EDU) to NASA Kennedy Space Center. The EDU is compact and intended for use in the ground-based plant growth chamber equivalents of the Advance Plant Habitat (APH) or VEGGIE.
