NASA has awarded approximately $2 million for 2 new research proposals to assist answer questions on astronaut health and performance during future long-duration missions beyond low-Earth orbit. The proposals will investigate biological, physiological, and behavioral adaptations to spaceflight using multiple International space platform flights and Earth-based studies to contribute to NASA’s preparations for crewed missions to the Moon and eventually Mars as a part of the Artemis program.
The selected proposals will receive a complete of roughly $2 million during a three- to six-year period. The projects, from two institutions in two different states, were selected from 23 proposals received in response to the 2018 Human Exploration Research Opportunities Appendix D, which solicited for projects investigating cardiovascular adaptations to long-duration spaceflight and for projects studying individual and team problem-solving skills training for exploration missions.
Benjamin Levine, professor of general medicine and Cardiology at the University of Texas Southwestern center at Dallas, will determine the effect of progressive durations of spaceflight on coronary anatomy and physiology, which relates to the arteries that surround the guts , and identify biomarkers which will be useful for early detection of accelerated atherosclerosis, a narrowing of arteries. Dr. Levine’s project are going to be incorporated into a complement of studies previously selected by NASA which will examine a spread of physiological systems including the brain, eyes, sensorimotor, musculoskeletal, bone, and immune among others.
