Genomics On Orbit

NASA astronaut and Expedition 64 Flight Engineer Kate Rubins collects tubes containing swab samples of microbes for the 3DMM (Three-dimensional Microbial Monitoring of ISS Environment) investigation.
The study analyzes and sequences the DNA from bacteria swabbed from station surfaces to understand how microbes respond at a molecular level to specific stress conditions, including altered gravity and atmospheric composition.
