Station Crew Preps Tools for Tuesday Spacewalk
July 12, 2013

[image-51]The Expedition 36 crew of the International Space Station finished out the week with scientific research, routine maintenance and preparations for a Tuesday, July 16, spacewalk to complete tasks begun on an excursion earlier in the week.

Following the crew’s daily planning conference with the flight control teams around the world, Flight Engineers Chris Cassidy and Luca Parmitano spent their morning preparing the tools they will use on next week’s spacewalk. During the excursion, currently slated to begin at 8:10 a.m. EDT Tuesday and last about six-hours and 15 minutes, Cassidy and Parmitano will primarily focus on completing tasks they began on their first Expedition 36 spacewalk on Tuesday, July 9. The two spacewalkers will finish the installation of bypass jumpers to provide power redundancy to critical station components, route additional cables for a new Russian Multipurpose Laboratory Module set to arrive later this year and perform additional maintenance and inspection tasks outside the station.

Before moving on to routine maintenance on the station’s Water Processor Assembly, Parmitano took a break to talk with Enrico Saggese, president of the Italian Space Agency, and reporters gathered at the agency’s headquarters in Rome.  Parmitano described his impressions of the July 9 spacewalk, the first for an Italian, and discussed the plans for the next excursion.

[image-78]Flight Engineer Karen Nyberg began her workday swapping out a battery for the EarthKAM camera mounted in the Window Observational Research Facility inside the Destiny laboratory.  EarthKAM allows students to program a digital camera aboard the station to photograph a variety of geographical targets for study in the classroom.

Later Nyberg collected and tested samples from the cooling systems of the Harmony node and the Destiny laboratory. Cassidy assisted with this task by collecting samples from the Tranquility node. Part of the station’s Environmental Control and Life Support System, the Internal Thermal Control System regulates the temperature of critical life support systems and payload racks.

Nyberg rounded out her day preparing test samples for the Advanced Colloids Experiment, or ACE, which is designed to help researchers understand how to optimize stabilizers to extend the shelf life of products like laundry detergent, paint, ketchup and even salad dressing.

Commander Pavel Vinogradov began his day conducting preventative maintenance on the ventilation system of the Zvezda service module. He later rounded up tools and equipment associated with the Treadmill with Vibration Isolation System, or TVIS, for return to the U.S. segment of the station.

Flight Engineer Fyodor Yurchikhin continued his work with the Kulonovskiy Kristall experiment, gathering data about charged particles in a weightless environment.  After consolidating some Russian spacewalk tools and electrical connectors, Yurchikhin finished his workday by collecting the data from Matryoshka.

Over the weekend, the crew will have an opportunity to speak with family members back on Earth and relax before next week’s spacewalk. The station’s residents also will take care of weekly housekeeping chores and continue their rigorous daily exercise regimen to prevent the loss of muscle mass and bone density that occurs during long-duration spaceflight.
