Expedition 52 is now up to full speed with six crew members. The latest trio from the United States, Italy and Russia arrived Friday afternoon beginning a 4-1/2 month mission in space.
The new crew is familiarizing itself with International Space Station systems and getting used to life 250 miles above Earth’s surface. NASA astronaut Randy Bresnik is starting his second space mission and spent time on Tuesday replacing networking hardware in the Japanese Experiment Module.
Astronaut Paolo Nespoli of the European Space Agency is on his third spaceflight. Nespoli took part in the Sarcolab-3 study using the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module. The data collected for Sarcolab-3 will be used to assess microgravity’s impact on muscle loss in astronauts, focusing specifically on the calf muscle in the leg.
Cosmonaut Sergey Ryazanskiy begins his second mission aboard the station as a flight engineer. He last visited the orbital complex in 2013 with his Expedition 37-38 crewmates. Ryazanskiy conducted routine maintenance across the station’s Russian segment and assisted Nespoli during the Sarcolab-3 experiment session.
