BRIC-23 GeneLab: Bacillus subtilis Omics Data from Spaceflight and Ground Control

Omics data from the BRIC-23 mission measures the response of the model organism Bacillus subtilis to the spaceflight environment aboard the International Space Station. The dataset includes transcriptomic, proteomic, and metabolomic data for comparison with matched ground controls and includes a specific experiment on the effects of slow freezing. It was produced by the National Aeronautics and Space Administration (NASA) as part of a process verification test for GeneLab Reference Missions.

Use Cases

• Compare microbial gene expression in space versus Earth based on transcriptomic data.
• Analyze protein abundance changes in response to spaceflight using proteomic data.
• Study metabolic shifts in Bacillus subtilis under spaceflight stress using metabolomic data.
• Assess the impact of slow freezing protocols on omics data quality as described in the control experiment.

Strengths

• Data is part of a formal NASA GeneLab Reference Mission designed to produce high-quality omics data.
• Includes a controlled experiment specifically designed to understand the effect of sample freezing rates on data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data for the related organism Staphylococcus aureus is deposited in a separate dataset (GLDS-145).
