The International Space Station’s Expedition 38 crew has begun unloading its delivery from the newly arrived ISS Progress 53 resupply craft. The long-term residents also conducted life science and reviewed emergency procedures.
Following its arrival on Friday, the hatches to the Progress 53 were opened on Saturday revealing the 2.9 tons of supplies it brought to the orbiting laboratory. The cargo craft docked to the Zvezda service module completing a four day journey that included a “flyby” to test its new Kurs automated rendezvous system.
NASA astronauts Mike Hopkins and Rick Mastracchio teamed up for the Spinal Ultrasound experiment and conducted backbone scans. The study observes vertebral changes caused by the forces of launch, landing and long-term exposure to microgravity.
Later, Hopkins worked with the long-running Capillary Fluids Experiment that studies the behavior of liquids in space. Observations from the experiment will help researchers design better fluid delivery systems, such as fuel and water, for future spacecraft.
Mastracchio continued his computer-based training as the station’s Crew Medical Officer. He later replaced an exercise rope on the advanced resistive exercise device.
Mastracchio also joined Japanese astronaut Koichi Wakata for eye exams in conjunction with medical ground support personnel. Past station crew members have reported changes in their eyesight and doctors are studying this phenomenon to mitigate future health risks.
From inside the seven-window cupola, Wakata started his day setting up a high definition video camera to record Earth views. He later cleaned a sampling adapter inside the Internal Thermal Control System which is part of the station’s Environmental Control and Life Support System.
On the Russian side of the space station, the three cosmonauts checked station systems, conducted science and performed fuel leak checks on the new Progress 53.
Commander Oleg Kotov worked throughout Monday unloading the Progress and updating the inventory management system. Later he photographed ocean environments to help locate productive areas for Russian fisheries.
Flight Engineer Sergey Ryazanskiy assisted Kotov during the Seiner ocean photography experiment. He also worked the Relaxation experiment which observes chemical reactions in the Earth’s atmosphere created by jet and spacecraft exhaust.
Mikhail Tyurin, a veteran of two previous station Expeditions, worked throughout the morning on laptop computer maintenance. He also transferred fluids, flushed tanks and participated in a video documentation of life on orbit.
All six crew members gathered together to review updated emergencies roles and responsibilities. The new emergency procedures were delivered aboard the Progress and highlight new escape routes and new fire prevention techniques.
