Current trace contaminant control (TCC) systems for removal of trace contaminant gases from cabin air are based on activated carbon filters and high temperature catalytic oxidation (HTCO). However, HTCO suffers from poisoning, and activated carbon suffers from absorbent saturation, which leads to off gassing. It also generates a secondary waste stream and becomes a microorganism breeding ground. During the Phase I effort, a bench scale TCC system utilizing a nanoparticulate photocatalytic filter was fabricated. Testing performed successfully demonstrated the technology feasibility for eliminating airborne chemicals and microorganisms. Preliminary equivalent system mass analysis shows the system efficacy and applicability to space missions. During the Phase II, a scaled-up, fully operational, flight qualifiable, microgravity compatible breadboard will be developed, tested with chemicals known to be present in International Space Station (ISS) cabin air, and delivered to NASA. Benefits of this reagentless approach are its low cost, low maintenance, reliability, longevity, size, performance, and elimination of a secondary waste stream. Photocatalytic unit implementation would serve to expand the capabilities of TCC technologies for missions beyond the ISS including Lunar and Martian exploration.","startYear":2004,"startMonth":11,"endYear":2006,"endMonth":11,"statusDescription":"Completed","programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
