In my recent EDN article, Man’s endeavor to live beyond Planet Earth, I discussed the present efforts of NASA and the Biosphere 2 in their efforts towards a Bio-Regenerative Life Support System (BLSS), a critical component for sustainable long-term space missions. NASA’s 2016 budget has allocated $55M for a DSH effort.
Now I will discuss the future efforts by NASA and the Biosphere 2 towards a functional BLSS.
Before we have a fully workable Mars-Lunar Greenhouse (MLGH), scientists will need to refine the prototype and optimize it for poly-cultivation (wide diversity of crops) systems integrated into the future BLSS architecture. The MLGH modules will become a necessary component for DSH.
The Biosphere 2 provides an excellent test facility for DSH development. The Biosphere 2 is the first DSH analog; it is a 3.1 acre, controlled environment research facility with diverse biomes: A desert, mangrove and wetland, and a tropical rainforest for this effort. See Figure 1.

To see what a Biosphere 2 ‘lung’ is and look like, see the YouTube video below:
The U of A goal is to construct a DSH prototype inside the Biosphere 2 west ‘lung’ in the form of an inflatable structure (See my EDN article mentioned in the first paragraph above)

Once the DSH is set up in the West ‘lung’, a Mars surface replica could be created along with an outreach program for Biosphere 2 visitors to view through a one-way glass viewing area so that the potential crews, who can occupy the facility for some days, can go about their work undisturbed—as if on Mars.

The CHM will be a two-level structure with the upper floor containing operating systems, water storage (radiation protection) and the cupola viewing room. It has an added I-beam with aluminum skin and additional supporting materials for strength.
Research will be done there once completed and some of the first research tasks will be:
1 Food production and diet
2 In-situ labor and telepresence
3 a study of dust penetration inside the habitat
This effort will help progress towards NASA’s pursuit of a Manned Mission to Mars and the Moon and deployment of a livable habitat while they are there. Stay tuned to Planet Analog and EDN for more progress in this area from my exclusive NASA visits.
