Researchers verified that 3D micro-computed tomography scans can map the orientation of plant roots in space and used the method to demonstrate that carrots grown in actual and simulated microgravity both had random root orientation. These findings suggest that simulated microgravity offers a reliable and more affordable tool for studying plant adaptation to spaceflight. MULTI-TROP evaluated the role of gravity and other factors on plant growth. Plant roots grow downward in response to gravity on Earth, but in random directions in microgravity, which is a challenge for developing plant growth facilities for space. Results…

Spooky on the Space Station

NeRD

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Science in Space: October 2024 Cultures around the world celebrate Halloween on Oct 31. In many places, in addition to people wearing costumes and eating candy, this day is associated with spooky decorating using fake blood, skeletons, flies, and spiders, some of them glow-in-the-dark. Crew members on the International Space Station have been known to indulge in a bit of dressing up and candy consumption to mark the day, and the research they conduct year-round occasionally involves these iconic…

Credit: NASA Prioritizing health is important on Earth, and it’s even more important in space. Exploring beyond the Earth’s surface exposes humans to conditions that can impact blood pressure, bone density, immune health, and much more. With this in mind, two NASA inventors joined forces 20 years ago to create a way to someday monitor astronaut…

Artemis I Radiation Measurements Validate Orion Safety for Astronauts

NeRD

On flight day 13, Orion reached its maximum distance from Earth during the Artemis I mission when it was 268,563 miles away from our home planet. Orion has now traveled farther than any other spacecraft built for humans. Credit: NASA NASA’s Orion spacecraft is designed to keep astronauts safe in deep space, protecting them from the unforgiving environment far from Earth. During the uncrewed Artemis I mission, researchers from NASA, along with several collaborators, flew payloads onboard Orion to measure potential radiation exposure to astronauts. Radiation measurements were taken inside…

Tissue Chips Accurately Model Organs in Space

NeRD

NASA astronaut Jessica Meir conducts cardiac research using tissue chip platforms in the Life Sciences Glovebox aboard space station in March of 2022. NASA The International Space Station offers a unique microgravity environment where cells outside the human body behave similarly to how they do inside the human body. Tissue chips are small devices containing living cells that mimic complex functions of specific human tissues and organs. Researchers can run experiments using tissue chips aboard space station to understand disease progression and provide faster and safer alternatives for preparing medicine…

Researchers found that long-duration spaceflight affected the mechanical properties of eye tissues, including reducing the stiffness of tissue around the eyeball. A better understanding of these changes could help researchers prevent, diagnose, and treat the vision impairment often seen in crew members. SANSORI, a Canadian Space Agency investigation, examined whether reduced stiffness of eye tissue contributes to vision impairment in astronauts on long-term missions. This condition, known as Spaceflight Associated Neuro-Ocular Syndrome, or SANS, includes a range of physical changes to the eyes. This paper suggests that biomechanical changes in the eye…
