Dr. Timothy Hammond (Duke University) and Dr. Holly Birdsall (Baylor College of Medicine) work for the Durham VA Health Care System and are the CoPrincipal Investigators for the Fuel to Mars study, one of four studies under NASA’s Biological & Physical Sciences Division’s Biological Experiment01 (BioExpt01) aboard Artemis I. The study will identify genes and gene pathways in algae (Chlamydomonas reinhardtii) that possess the best survival advantage during exposure to the combined effects of space radiation and microgravity. These will be used as parent strains in future studies to optimize generation of hydrogen and other essential fuels in space.
