2Overview of Deep Space Habitat Work. KSC involved in this AES DSH project which has revolved around HDU in the past and is now moving to ISS-derived DSH as part of an exploration architecture. X-Hab is an interesting academic innovation challenge where university teams compete to build concepts with our multi-center team. See web site for upcoming call opportunity ~April 2012 for FY14 projects. This program gives university teams the opportunity work with our team to develop a small project that contributes to habitation. Proposals come with some small funding but are judged by in kind contributions, integration into an academic program, outreach, and technical merit.2

Projects like these are often funded by local centers like KSC through Center Innovation Fund calls. There are opportunities to partner with NASA researchers on projects like these than can contribute to agency level projects like AES DSH. Demos like these give greater visibility for the researchers and better products for the projects thus a win-win and sum is greater than a total of its parts approach.3

This system will provide the ability to monitor the integrity of a composite or inflatable habitat with in situ system health monitoring.

You might even state it as ecological stability / sustainability. It would be most useful for NASA to look at the microbial level (e.g., setting up a microbial observatory on ISS).13Related ISS Payload Development14Some of these areas have matured to building flight hardware for the ISS14Food Production UnitsVEGGIE15

This is a KSC developed flight payload being prepared for the ISS. The concept is to demonstrate plant growth to supplement the crew's diet with fresh, perishable foods and herbs while on exploration campaigns.
