Arizona designed the <strong>Prototype Lunar Greenhouse<\/strong> to feed astronauts, freshen the air, and recycle water and nutrient wastes in space. This greenhouse is inflatable and collapsible, equipped with a hydroponics system and <a href=\"https:\/\/astrobotany.com\/optimal-lighting-for-plants-in-space\/\" target=\"_blank\" rel=\"noopener\">grow lights<\/a>. The walls are transparent to allow sunlight to shine on the plants. The LGH is surprisingly easy to build because it deploys autonomously, meaning it is deployed and constructed by computers instead of astronauts.<\/p><p>Since 2004, Phil Sadler, Robert Furfaro, and Gene Giacomelli have worked on the LGH with 30-40 dedicated students, faculty, staff, and international collaborators.<\/p><figure class=\"wp-block-image aligncenter size-large is-resized\"><img decoding=\"async\" class=\"wp-image-3966\" style=\"width: 747px; height: 398px;\" src=\"https:\/\/astrobotany.com\/wp-content\/uploads\/2021\/02\/LGH1.jpg\" alt=\"\" width=\"747\" height=\"398\" srcset=\"https:\/\/astrobotany.com\/wp-content\/uploads\/2021\/02\/LGH1.jpg 750w, https:\/\/astrobotany.com\/wp-content\/uploads\/2021\/02\/LGH1-300x160.jpg 300w, https:\/\/astrobotany.com\/wp-content\/uploads\/2021\/02\/LGH1-600x320.jpg 600w\" sizes=\"(max-width: 747px) 100vw, 747px\" \/><\/figure><p>Though it is unclear whether this lunar greenhouse will ever be deployed in space, we have learned a lot from it. In 2015, scientists tested multi-cropping systems in this greenhouse. <b>Multi-cropping<\/b> is the practice of growing two or more crops in the same growing space. Multi-cropping can improve yields in traditional agriculture, but it has never been tested in space\u2014meaning data from these multi-cropping experiments may inform our future space gardening decisions. Alongside the role of the LGH as a space greenhouse, its other purpose is to provide a practical commercial-ready controlled environment greenhouse for use on Earth. Even if the LGH is never used on the Moon or Mars, it is still a valuable research tool for understanding how we can grow plants on Earth and beyond.<\/p><p><strong>The LGH as a Bioregenerative Life Support System:<\/strong><\/p><p>This greenhouse is a Bioregenerative Life Support System (BLSS) because it recycles waste products (namely CO<sub>2<\/sub> and nutrient waste) and provides food. BLS systems provide five main services: 1) atmosphere revitalization, 2) water recycling, 3) food production, 4) organic waste recycling, and 5) power generation. Dr. Gene Giacomelli says, \u201cWe\u2019re mimicking what the plants would have if they were on earth, and using these processes for life support. The entire system of the Lunar Greenhouse does represent, in a small way, the biological systems that are here on Earth\u201d.<\/p><figure class=\"wp-block-image aligncenter size-large
