NASA Is Testing Whether Cartilage Prints Better in Microgravity
On 9 October 2026, NASA astronaut and Expedition 75 flight engineer Jessica Watkins worked inside the Kibo laboratory module's Life Science Glovebox, mixing living cell samples with a bioink and then filling a special cartridge with the cell-ink mixture.
The work was part of the InSPA-Auxilium Bioprinter-Cell Printing investigation, which explores 3D bioprinting cartilage tissue in microgravity of higher quality than cartilage produced on Earth. NASA says the results may advance the ability to biomanufacture cartilage, benefiting patients on Earth and crew members on long-duration space missions.

Keep the aim separate from the achievement: what's described is an investigation into whether microgravity produces better cartilage, and results that may help — not a finished graft with a timestamp on it.
Two beneficiary groups get named, Earth patients and long-duration crews, and which one you find more compelling probably says whether you read space biology as medicine or as life-support engineering.
