Firing up a new alloy

A new alloy is being developed through the testing of a sintering process in microgravity aboard the International Space Station. The investigation uses liquid phase sintering to study the degree of distortion caused by microgravity, with potential applications for space manufacturing and Earth-based industries.

Home is where the astronaut is

The study investigates changes in perceptions about home in space and the development of a unique culture among astronauts. Researchers found that a shared space culture can help crew members respond to different situations, reducing stress and improving morale.

Fishing for answers on bone loss in space

Researchers aboard the International Space Station reared small freshwater fish for 56 days to investigate microgravity's effects on bone density. The study found increased osteoclast activity and reduced bone mineral density in the fish, suggesting a potential link between mitochondria dysfunction and osteoporosis.

An orange a day keeps scurvy away

Astronauts' nutritional needs are crucial for long-duration space missions, as microgravity and radiation exposure impact health. NASA's Biochemical Profile project aims to understand the effects of spaceflight on nutrition and develop strategies to mitigate negative effects.

May the force (shoes) be with you

Researchers will use the ForceShoe to measure exercise loads and ground reaction forces, aiming to understand how joint forces differ between Earth-based exercises and those in microgravity. The goal is to recommend optimal exercise regimens for safe bone and muscle strength maintenance during spaceflight.

It's all in your head

Researchers are exploring methods to monitor and understand intracranial pressure through the ear, eye, and head. These non-invasive techniques aim to provide accurate and safer ways to determine the correlation between intracranial pressure and vision impairment.

Orbital samples with sight-saving potential

Two studies examine the effects of spaceflight on mouse eyes, revealing oxidative stress as a key mechanism behind eye damage. Researchers found genes involved in response to oxidative stress and potential indicators of optic nerve damage, highlighting the need for countermeasures to protect astronauts' vision.
