The Expedition 38 crew of the International Space Station wrapped up the first week of 2014 Friday with physics and biomedical research. Meanwhile, the newest commercial cargo vehicle to join the station’s resupply fleet is set to roll out to its launch pad this weekend for its inaugural operational flight to the station next week.

Flight Engineer Koichi Wakata spent much of his morning participating in the Body Measures experiment, which collects anthropometric data to help researchers understand the magnitude and variability of the changes to body measurements during spaceflight. Predicting these changes will maximize crew performance, prevent injury and reduce time spent altering or adjusting suits and workstations to accommodate anthropometrics. Flight Engineer Rick Mastracchio assisted Wakata throughout the experiment session, setting up the calibration tape, collecting data and taking photographs.

Afterward, Wakata teamed up with Flight Engineer Mike Hopkins for another round of Ocular Health examinations. Vision changes have been observed in some astronauts returning from long-duration spaceflight, and researchers want to learn more about its root causes and develop countermeasures to minimize this risk. With assistance from the Ocular Health team on the ground, the two astronauts conducted ultrasound scans of each other’s eyes, monitored blood pressure and collected echocardiogram data.

Mastracchio rounded out his day with the Capillary Flow Experiment, which takes a close look at how fluids flow across surfaces with complex geometries in a weightless environment. Results from this experiment will improve computer models used to design fluid transfer systems and fuel tanks on future spacecraft. These systems are crucial as NASA develops technologies that will take astronauts deeper into space than ever before.

On the Russian side of the complex, Commander Oleg Kotov performed the Bar experiment, studying methods and instruments for detecting the location of an air leak from one of the station’s modules.

Flight Engineer Mikhail Tyurin inspected and photographed the windows in the Russian segment to document the condition of their seals and the locations of any scratches.

Flight Engineer Sergey Ryazanskiy conducted another session of the Coulomb Crystal experiment, gathering data about charged particles in a weightless environment.

As the station’s crew wrapped up its workday Friday, ground controllers at Houston’s Mission Control Center began the process of remotely performing a “walkoff” of the Canadarm2 robotic arm. With Thursday’s robotic inspection of the Alpha Magnetic Spectrometer completed, the ground team will command Canadarm2 to reach out and latch on to a Power and Data Grapple Fixture on the Harmony module and release the other end of the 57-foot robotic arm from the station’s railcar, the Mobile Base System.

The relocation of Canadarm2 sets the stage for the arrival of Orbital Sciences Corporation’s Cygnus cargo craft, scheduled to launch on its first operational resupply mission to the station at 1:55 p.m. EST Tuesday. When Cygnus arrives at the station Jan. 10, Hopkins and Wakata will be standing by to capture the capsule with the station’s robotic arm and install it on the Earth-facing port of Harmony.

The Antares rocket, which will carry Cygnus and its 2,780 pounds of cargo into orbit, is set to roll out to launch pad 0A at the Wallops Flight Facility in Virginia Saturday night.
