BRIC-21 Bacillus subtilis transcriptome profile data

Published by Open Science Data Repository | National Aeronautics and Space Administration | Metadata Last Checked: August 25, 2025 | Last Modified: 2025-08-21
The BRIC-21 mission was designed to identify the response of Bacillus subtilis to the human spaceflight environment. For this mission, samples were grown in rich-medium using the Biological Research in Canister Petri Dish Fixation Units (BRIC-PDFU) spaceflight hardware. B. subtilis spores were inoculated during spaceflight, grown at the ambient ISS temperature, and frozen in the onboard -80 C freezer prior to returning to Earth. RNA was extracted from samples grown onboard the International Space Station (ISS) and matching Ground Controls for transcriptome analysis.
