Due to an administrative glitch, the Astromaterials Acquisition and Curation Office at the NASA Johnson Space Center is reposting a position opening for a specialist in the field of geomicrobiology or astrobiology. Qualified candidates who applied previously are encouraged to re-apply. The successful candidate will serve NASA as curator for biological components in astromaterials. Specifically, we seek an individual with current expertise in at least one of the following areas: (1) biological cleanliness and quantitative biological contaminant characterization; (2) chemical, mineralogical, or petrological consequences of microbial interaction with astromaterials, astromaterials simulants, and terrestrial analogs of astromaterials; (3) sample collection and handling (including transport, containment, preservation, and curation) of geological materials that contain microbial matter. The successful candidate should have a Ph.D. and at least 2 years of relevant post-graduate experience, and a demonstrated record of contributions to the field. The candidate shall develop an externally funded research program in the area of geomicrobiology and/or astrobiology. Additional duties include development and implementation of curation plans for astromaterials returned from future missions with possible extraterrestrial biological components; conducting advanced curation research to prevent biological contamination of NASA’s past, present, and future astromaterials collections. Furthermore, he or she will be expected to develop methods of monitoring for biological contamination within curation facilities and in NASA’s astromaterials collections. This individual will also provide expertise in the area of contamination knowledge as it relates to biological cleanliness of NASA spacecraft at all stages of a mission. The position is posted at USAJobs at http://www.usajobs.gov/GetJob/ViewDetails/450322000, starting 9/14 and closing 10/5, 2016.
