The crew aboard the International Space Station continued exploring the numerous ways living in space affects the human body and other organisms. The station residents also participated in an emergency simulation exercise.
Commander Jeff Williams and Flight Engineer Oleg Skripochka this week are exploring fluid shifts from an astronaut’s lower body to the upper body during long-term space missions. This phenomena that occurs in microgravity increases pressure on a crew member’s brain and eye structure potentially affecting vision.
NASA astronaut Kate Rubins relocated an incubator that houses Heart Cells research samples from one science rack to another. Those samples will be analyzed on Earth when the SpaceX Dragon returns the research at the end of August. Japanese astronaut Takuya Onishi continued the upkeep of an experiment that is researching genetic alteration in mice and their offspring due to the microgravity environment.
All six Expedition 48 crew members joined each other in the afternoon to practice their response to an unlikely emergency situation. The astronauts and cosmonauts practiced communication and coordination in conjunction with Houston and Moscow control centers in response to emergency simulators.
