If humans want to explore the Moon, and later Mars, the crews must be provided with medical care and at the same time the operation of life-support systems must be improved. 3D bioprinting – that is, 3D printing involving living cells – shows great potential for both requirements. The knowledge gained from this parabolic flight mission will help to better understand the influence of microgravity on the 3D bioprinting process. The team from TU Braunschweig / Carl Gustav Carus University Hospital Dresden wants to use DALERA to prepare experiments for use on board the ISS, where a 3D bioprinter is to be installed by the European Space Agency (ESA) for research purposes by the end of 2026.
