This federal contract award, identified as 80NSSC18K1058, was granted to Portland State University by the National Aeronautics and Space Administration (NASA) for scientific research related to the agency's Exobiology program. The $775,267.90 grant is funding a project that aims to achieve a deeper understanding of the unusual sulfide-based assimilatory sulfur metabolism found in some of Earth's earliest anaerobic organisms. The research involves experimental and computational methods, including...
This is a $242,742.04 grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to Portland State University, a U.S. state government and public educational institution, for research related to the potential role of atmospheric aerosols in the origin of life. The grant does not have a set-aside designation. The award builds on the work of Carl Woese, who in 1979 proposed a greater role for atmospheric aerosols in the transition from prebiotic to...
This federal contract award, worth $250,632.00, was granted by the Shared Services Center (part of the National Aeronautics and Space Administration) to Portland State University (PSU) to expand the understanding of Nanoarchaeota and Korarchaeota, two groups of hyperthermophilic archaea, across distinct marine and terrestrial geothermal environments. The goal is to study the evolution, diversification, and symbiotic/parasitic relationships of these ancient lineages as a way to trace back the...
This is a grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Florida (UF) to conduct research on methanogens, a type of microorganism, under simulated Martian conditions. The $542,194.21 grant, awarded on June 15, 2017, is focused on establishing the limits for metabolism, growth, and methane production of psychrophilic (cold-loving) methanogens under low pressure, low temperature, low oxygen, and high perchlorate/chlorate salt conditions that may...
This is a $358,750.01 grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University for research on the chemical mechanism responsible for the mass-independent fractionation of sulfur isotopes seen in Archean sedimentary rocks. The research will involve measuring high-resolution photoexcitation cross sections, dissociation probabilities, and rates of collisional and radiative deactivation of excited-state sulfur species. The results will be incorporated...
This is a grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to Portland State University (PSU) to conduct applied science and engineering research on advanced life support systems for space exploration. The $387,364.70 grant is for developing solutions to NASA's needs in areas such as passive biofluids management, water delivery and management for plants in space, and crowd-sourcing plant root water delivery methods. The research will involve...
This is a $100,158 grant awarded by the National Aeronautics and Space Administration (NASA) to Montana State University (MSU) under the Exobiology program. The grant is to support the research of an MSU assistant professor on developing novel bioorthogonal labeling tools to study extremophilic microbes in geothermal hot springs. The research aims to provide a better understanding of the biotic and geochemical factors that drive microbial activity, which is relevant to NASA's Exobiology...
This is a grant award from the National Aeronautics and Space Administration (NASA) to the SETI Institute, a non-profit scientific organization, for a research project titled "Biosynthesis of 3-Methylhopanoids by Purple Non-Sulfur Anoxygenic Phototrophs." The project aims to investigate the cellular function of certain lipid biomarkers in purple non-sulfur bacteria and their potential implications for interpreting the geological record. The grant has a total ceiling value of...
This is a $360,000.00 grant awarded by the National Aeronautics and Space Administration (NASA) to Michigan State University (MSU) to research the evolution of microbial metabolic networks. The research aims to understand how different metabolisms may arise and what environmental conditions select for various types of metabolic networks, particularly in the context of early microbial evolution on Earth and potentially other habitable planets. The research will combine two novel modeling...
The University of Southern California (USC) has been awarded a $1,983,901.56 research grant by the National Aeronautics and Space Administration (NASA) to investigate the role of iron redox cycling in the formation and decline of stromatolites, which represent some of the earliest macroscopic evidence of life on Earth. The grant, titled "STROMATOLITES LAMINATED, LITHIFIED STRUCTURES TYPICALLY BUILT BY MICROBIAL MATS REPRESENT THE MOST ABUNDANT RECORD OF LIFE IN THE FIRST 7/8THS OF EARTH...
This is a $858,990.51 grant awarded by the National Aeronautics and Space Administration (NASA) to Portland State University (PSU) for research on the biological sulfur metabolism of methanogens, ancient microorganisms that emerged on the anaerobic Earth over 2 billion years ago. The grant, titled "DESCRIPTION OF KEY CENTRAL OBJECTIVES SULFUR ASSIMILATION AND TRAFFICKING IN METHANOGENS EXHIBIT UNIQUE FEATURES AS COMPARED WITH ALL OTHER EXTANT ORGANISMS, REFLECTING THE EMERGENCE OF THESE ARCHAEA ON THE ANAEROBIC EARTH OVER TWO BILLION YEARS AGO", aims to identify novel genes involved in sulfide uptake and sulfur trafficking, and characterize the associated proteins and their interactions. This research is highly relevant to NASA's Astrobiology Roadmap, as it seeks to understand how life on Earth and its planetary environment have co-evolved through geologic time. The grant does not have a set-aside designation, indicating it was awarded through open competition.
