Radiation Data in the NASA GeneLab Omics Database
Abstract
NASA GeneLab is an interactive, open-access database for sharing and analysis of omics data from spaceflight and ground analog experiments. Data on the environmental conditions experienced by the biological samples are an important component of the GeneLab Data System (GLDS). One of the most critical environmental factors is radiation exposure. Accurate data on radiation dose for flight experiments can be challenging to obtain, with inherent uncertainties in location relative to on-board dosimeters and in experiment timing. There are also variations in dosimeter technology among vehicles and among the various ISS modules. Data in the GLDS include absorbed doses and dose rates recorded on the Space Shuttle, ISS and biosatellites. Data from ground studies at proton and heavy ion accelerators are also incorporated in the GLDS, broken out by ion, energy (and/or LET) in addition as dose and dose rate. We will present examples of the radiation data available in the GLDS, and discuss how GeneLab is generating the metadata tags for ionizing radiation terms necessary to fully characterize both spaceflight data and ground studies simulating space radiation. Our goal is to establish a data submission portal and a well-defined ontology for users to self-curate their data. Lastly, we will discuss ideas for more accurate dosimetry for biology payloads on future space flights.
