WASHINGTON, April 2, 2013 /PRNewswire-USNewswire/ -- NASA is seeking innovative, early-stage space technology proposals from accredited U.S. universities that will enable NASA's future missions and America's leadership in space. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Proposals are sought for science instruments, cryogenic propellant storage for long-duration space exploration, optical coatings for astrophysical pursuits, oxygen recovery for life support systems, and to improve our understanding of and protection from near-Earth asteroids. Each of these space technology areas requires dramatic improvements over existing capabilities. New early stage, or low technology readiness-level, technologies could mature into tools that solve the hard challenges facing NASA's future scientific and human spaceflight missions. Researchers should propose unique, transformational space technologies that address specific topics found in this solicitation. "Space technology is the underpinning of all of NASA's future missions," said Michael Gazarik, NASA's associate administrator for the Space Technology Mission Directorate in Washington. "NASA's collaboration with the National Research Council and the agency's recent Strategic Space Technology Investment Plan have helped us identify areas where new, cross-cutting space technologies are needed to enable our future missions. Now we're reaching out to American universities to tap into the nation's best and brightest minds to help solve these tough technology problems." This solicitation requests proposals on five topic areas. The first topic area seeks new instrument technologies for the exploration of planetary bodies within our solar system. Innovative technology advances are needed to support the instruments that scientists will need to better understand the history, climates, evidence of past life and future potential habitability of planets and moons within the solar system. Spaceflight architectures for future human space exploration beyond low-Earth orbit will require technologies and capabilities not available today, such as long duration storage of cryogenic propellants in a zero gravity environment. Under a second topic area for this solicitation, NASA is particularly interested in proposals regarding how to mature fundamental experimental and computational solutions to address the challenges of cryogenic storage of liquid hydrogen.
