AbstractThe proposed project is the continued development of the High Efficiency Lighting with Integrated Adaptive Control (HELIAC) system. Solar radiation is not a viable option for growing plants on the Moon or on Mars for multiple reasons. On the other hand, lighting plants with electric lamps and rejecting the associated waste heat has associated energy costs that have driven NASA toward other options to provide food and fresh air to future Mars crews The HELIAC lighting system consists of small individual LED "light engines" that provide a level of control precision far in excess of standard lamps. This precision enables lamp configuration to be adapted to species specific growth habits so that photons can be absorbed efficiently by all available photosynthetic tissues. HELIAC will also provide the capability to adapt spectral balance automatically to plant development stage. Finally, it will have the capability to automatically detect the proximity of plant tissue and power only adjacent light engines, thereby greatly decreasing power requirements, particularly in the early stage of plant development.
