Science is in full swing aboard the International Space Station today as the Expedition 65 crew studies how microgravity affects the human body. Back on Earth, four Commercial Crew astronauts are less than two days away from launching to the orbiting lab from Florida.
Blood samples, muscle scans and exercise were the subjects of Tuesday’s space research to learn how the human body adapts to weightlessness. To start the day, Flight Engineers Michael Hopkins and Soichi Noguchi collected their blood samples and stowed them in a science freezer for later analysis. Hopkins then joined Flight Engineer Victor Glover for muscle scans using an ultrasound device to understand how space impacts muscle tone, stiffness and elasticity.
NASA astronaut Mark Vande Hei, who is in his second week aboard the station, attached sensors to his chest and worked out on a stationary bike for another human research experiment during the day. The exercise study measures an astronaut’s aerobic capacity and the effort required to perform strenuous activities such as spacewalks.
Another muscle study is observing changes in the genetic expression of ...
