Preparations for Next Moonwalk Simulations Underway (and Underwater)<\/h1>\n<\/div>\n<\/div>\n<\/div>\n

Studies of neurological organoids, plant growth, and shifts in body fluids are among the scientific investigations that NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Tracy C. Dyson will help support aboard the International Space Station as part of Expedition 71. The crew members are targeting launch<\/a> to the space station in February and March.<\/p>\n

Here are details on some of the work scheduled during this upcoming expedition aboard the microgravity laboratory:<\/p>\n

Modeling Neuroinflammation<\/strong><\/h2>\n

Human Brain Organoid Models for Neurodegenerative Disease & Drug Discovery (HBOND<\/a>) studies the mechanisms behind neuroinflammation, a common feature of neurodegenerative disorders. Researchers create organoids using patient-derived iPSCs (induced pluripotent stem cells) from patients who have Parkinson\u2019s disease and primary progressive multiple sclerosis. The sixth space station organoid investigation funded by the National Stem Cell Foundation, HBOND includes for the first time Alzheimer\u2019s iPSCs and testing of the effects of drugs in development to treat neuroinflammation. Results could help improve diagnostics, provide insights into the effects of aging, accelerate drug discovery, and identify therapeutic targets for patients suffering from neurodegenerative diseases. The organoid models also could provide a way to anticipate how extended spaceflight affects the brain and support development of countermeasures.<\/p>\n

Protecting Plants from Spaceflight Stressors<\/strong><\/h2>\n

Plants can serve as a source of food and provide other life-support services on long-term missions to the Moon and Mars. The Study on Plant Responses Against the Stresses of Microgravity and High Ultraviolet Radiation in Space (Plant UV-B<\/a>) examines how stress from microgravity, UV radiation, and the combination of the two affect plants at the molecular, cellular, and whole organism levels. Results could increase understanding of plant growth in space and support improvements in plant cultivation technologies for future missions.<\/p>\n

Positive Pressure<\/strong><\/h2>\n

Microgravity causes fluids in the body to move toward the head, which can cause changes in eye structure and vision known as Spaceflight Associated Neuro-ocular Syndrome (SANS) and other health problems. Mitigating Headward Fluid Shifts with Veno-constrictive Thigh Cuffs During Spaceflight (Thigh Cuff<\/a>) examines whether thigh pressure cuffs could provide a simple way to counter this shift of body fluids and help protect astronauts from SANS and other issues on future missions to the Moon and Mars. Thigh cuffs also could help treat or prevent problems for patients with conditions on Earth that can cause fluid accumulation in the body, such as long-term bedrest and diseases.<\/p>\n

Incredible Edible Algae<\/strong><\/h2>\n

Arthrospira-C (Art-C<\/a>), an investigation from ESA (European Space Agency) analyzes how the cyanobacterium Limnospira <\/em>responds to spaceflight conditions and whether it produces the same quantity and quality of oxygen and biomass in space as on Earth. These microalgae, also known as Spirulina, could be used to remove carbon dioxide exhaled by astronauts, which can become toxic in an enclosed spacecraft, and to produce oxygen and fresh food as part of life support systems on future missions. Correct predictions of oxygen and biomass yields are crucial for design of life support systems using bioprocesses. Spirulina also has been shown to have radioprotective properties and eating it could help protect space travelers from cosmic radiation, as well as conserve healthy tissue in patients undergoing radiation treatment on Earth.<\/p>\n
