Reducing reliance on resupply missions

Resupply of life support elements such as air, water, food, clothing, and hygiene items will be impractical on missions to the Moon and beyond.

assessed current use and resupply of these elements on the International Space Station and outlines technologies needed for sustained human presence in space, such as 3D printing maintenance parts, systems for laundering clothes, and improved recovery and recycling of elements.

Researchers analyzed the types and mass of elements supplied from Earth to the station and astronaut feedback from various studies and interviews. The paper also used data from

presents a review of examining the behavior of emulsions (suspensions of particles in a liquid) in microgravity using a technique called diffusing wave spectroscopy. Results offer insights that could support development of technologies to improve living environments and foods for crew members on future missions.

EEG measurements and predicting cognitive changes in spaceflight

Researchers used an electroencephalogram (EEG) to measure brainwave activity during a relaxed, wakeful state in crew members and

before, during, and after flight. These types of measurements could serve as biomarkers of brain health status, helping to predict changes in cognitive performance and the need for prevention and countermeasure strategies during future missions.

Studies have shown that spaceflight can affect key cognitive and motor skills such as task management, attention, and movement speed and accuracy.
