NASA is set to launch its 33rd commercial resupply mission to the International Space Station (ISS) aboard the SpaceX Dragon spacecraft in late August. The mission aims to test several innovative technologies, including 3D bioprinting of implantable medical devices, observing engineered liver tissues, and examining microgravity’s effects on bone-forming cells.
One key focus is creating an implantable device that could support nerve regrowth after injuries. Researchers plan to print up to 18 implants using living cells or proteins as raw materials, with the goal of accelerating recovery and preserving function. This technology has the potential to revolutionize treatment options for individuals with traumatic injuries.
Engineers will also test bioprinted liver tissue containing blood vessels, aiming to develop vascular networks that could support the eventual production of entire functional organs for transplantation on Earth. A previous mission tested similar bioprinted liver tissue in space, and this round aims to assess its development in microgravity.
Furthermore, scientists are investigating the effects of microgravity on bone-forming cells, seeking to understand the mechanisms behind bone loss experienced by astronauts during space flight. They aim to identify a protein that can be targeted to reduce bone loss, with potential applications for osteoporosis and certain types of cancers.
Additionally, researchers will conduct a study on 3D printing with metal in space, building on recent successes in plastic printing. This investigation aims to determine the optimal approach for metal printers in space and develop in-space manufacturing capabilities.
The SpaceX Dragon spacecraft is scheduled to launch to the orbiting laboratory in late August, marking an exciting milestone in NASA’s efforts to advance space exploration and provide benefits to humanity.
