Researchers tested a treatment on cartilage and bone tissue cultures subjected to compressive impact injury and found differences in the metabolites and proteins released by cells in space and on Earth along with partial improvement in both gravity conditions. The findings suggest the treatment is safe and could help ensure the health of crew members on future missions and patients on Earth.
Astronauts have high rates of musculoskeletal injuries, and post-traumatic osteoarthritis from joint injuries is a major contributor to disability across all ages on the ground. MVP Cell-06 used cultures of human knee cartilage and bone cells from two donors to study how spaceflight affects musculoskeletal disease. Results could lead to ways to prevent and treat bone and cartilage degradation in astronauts and people on Earth following joint injury.
NASA and Roscosmos researchers examined brazing of an aluminum-silicon material and found that gravity had a moderate effect with small quantities of the alloy and a more significant effect with larger quantities. The finding could inform techniques for manufacturing on future space missions.
SUBSA-BRAINS examined capillary flow, interface reactions, and bubble formation during solidification of brazing alloys in microgravity. Brazing, which bonds similar and dissimilar materials at temperatures above 450°C, is a potential tool…
