Manufacturing tools and medicine in space is a key objective for NASA and its international partners as crews train for longer missions farther away from Earth. Humans living in space habitats will need to be self-sufficient to stay heathy and run successful missions since launching supplies from Earth will be less feasible and uneconomical.

NASA astronauts Jeanette Epps of Expedition 71 and Suni Williams, Pilot for Boeing’s Crew Flight Test, joined each other in the Columbus laboratory module and configured the Metal 3D printer on Wednesday. The duo first uninstalled the device from Columbus’ European Drawer Rack-2 (EDR-2), a multipurpose experiment rack, to access an experimental sample printed with stainless steel. They replaced a substrate in the advanced manufacturing hardware then reinstalled the 3D printer back in the EDR-2. Researchers are exploring how the Metal 3D printer operates in the microgravity conditions of weightlessness and radiation as well as its ability to manufacture tools and parts on demand during space missions.

NASA Flight Engineer Mike Barratt explored how stem cells grow in microgravity to improve cell therapies on Earth and cell manufacturing in space. Working in the Kibo laboratory module, Barratt serviced stem cell samples inside the Life Science Glovebox. The cells are undergoing a cellular reprogramming process and the samples will be returned to Earth for further analysis. Scientists are pursuing the production of stem cells in space that can be regenerated into human cells or tissues for personalized medicine.

Flight Engineer Matthew Dominick partnered with Crew Flight Test Commander Butch Wilmore, both NASA astronauts, checking CubeSat configurations before they are deployed into Earth orbit. The duo ensured the shoebox-sized satellites were secured in their launch cases and clear of debris inside the Small Satellite Orbital Deployer they are packed in. Afterward, they installed the deployer onto a multipurpose experiment platform and loaded it inside Kibo’s airlock where it will soon be placed in the vacuum of space to release the CubeSats for a variety of research.

NASA Flight Engineer Tracy C. Dyson focused on housekeeping tasks as she cleaned the crew quarters in the starboard side of the Harmony module. She vacuumed dust collected on ventilation systems and wiped down surfaces inside the module where Boeing’s Starliner and the SpaceX Dragon Endeavour spacecraft are docked.

Working in the Roscosmos segment of the orbiting lab, Commander Oleg Kononenko set up Earth observation gear, inspected the aft vestibule of the Zvezda service module, then explored futuristic planetary and robotic piloting techniques. Flight Engineer Nikolai Chub assisted Kononenko with the Zvezda checks then he explored how microalgae can be used to produce oxygen and consume carbon dioxide improving space life support systems. Flight Engineer Alexander Grebenkin spent his day on life support maintenance transferring from resupply tanks and performing coolant leak checks on the aur conditioning system.
