Researchers demonstrated the feasibility of 3D bioprinting a meniscus or knee cartilage tissue in microgravity. This successful result advances technology for bioprinting tissue to treat musculoskeletal injuries on long-term spaceflight or in extraterrestrial settings where resources and supply capacities are limited. BFF Meniscus-2 evaluated using the BioFabrication Facility to 3D print knee cartilage tissue using [...]

NASA and the military have shared strong connections since the agency’s early days. From the nation’s earliest aeronautic research and the recruitment of test pilot astronauts to modern-day technology development, satellite management, and planetary defense, NASA has built a longstanding partnership with the military. This legacy of collaboration has created natural opportunities for former service [...]
