Life sciences continued to dominate the research calendar aboard the International Space Station on Wednesday for the benefit of humans living on and off Earth. Expedition 67’s seven orbital residents explored how life in microgravity affects tissue regeneration, crew psychology, and the human digestive system.

Learn to heal wounds in space is essential as NASA and its international partners plan crewed missions to the Moon, Mars and beyond. Four astronauts from the station teamed up this week for the skin-healing study taking place inside the Kibo lab module. Flight engineers Kjell Lindgren, Bob Hines and Jessica Watkins, all of NASA, with Samantha Cristoforetti of ESA (European Space Agency), study surgical techniques such as biopsies, suture splints and dressings, at the Inside the Kibo Life Science Glove Box.

Scientists on Earth seek to identify the molecular mechanisms that occur during tissue regeneration in weightlessness. Observations can offer advanced therapies and provide insight into how accelerated skin aging caused by space affects an astronaut’s healing properties. Biomedical experience can also contribute to better wound healing techniques on Earth.

Three of the astronauts also had time today for a cognitive assessment between the skin healing study. Lindgren, Hines and Watkins all took turns practicing simulated robotic capture of a spacecraft on a computer to understand how an astronaut might perform stressful activities on future space missions. One of six tests that are part of the Basic behavioral measures human research experience, the robotics session helps researchers reliably assess adverse cognitive or behavioral conditions that astronauts may encounter during long-duration spaceflight.

Two cosmonauts performed ultrasound scans of their digestive systems after having breakfast on Wednesday morning. Commander Oleg Artemyev and Flight Engineer Denis Matveev this week explore how microgravity affects the digestion process with potential applications for Earth-bound conditions. Flight Engineer Sergey Korsakov spent the day testing controls and operations on the European robotic arm attached to the Nauka Multipurpose Laboratory Module.
