Station Crew Set for a Spacewalk on Tuesday
July 15, 2013


Expedition 36 crew members living and working aboard the International Space Station on Monday wrapped up a variety of preparations for a spacewalk and continued their work with an assortment of science experiments.

The spacewalk is set to begin at 8:10 a.m. EDT Tuesday morning and last about six-hours and 15 minutes. Flight Engineers Chris Cassidy of NASA and Luca Parmitano of the European Space Agency will focus primarily on completing tasks they began on their first Expedition 36 spacewalk July 9. Coverage of the spacewalk will begin at 7 a.m. on NASA TV.

During the excursion, 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,  replace a video camera on the Japanese Exposed Facility experiment platform, relocate wireless television camera equipment, troubleshoot a balky door cover over electronic relay boxes on the station’s truss and reconfigure a thermal insulation over a failed electronics box that was removed from the station’s truss last year.

It will be the 171st spacewalk in support of station assembly and maintenance, the fifth conducted at the station this year, the sixth of Cassidy’s career and the second for Parmitano. Cassidy will wear the spacesuit with red stripes, while Parmitano will wear the spacesuit with no stripes or markings.

Cassidy and Parmitano spent much of the day Monday working in the Quest airlock preparing an array tools and equipment they will use during Tuesday’s spacewalk.


In other spacewalk preparations, Cassidy and Parmitano took part in health status checks with Flight Engineer Karen Nyberg acting as Crew Medical Officer. They were later joined by Flight Engineer Fyodor Yurchikhin for a spacewalk procedure and timeline review with ground teams.

In the Russian segment of the orbiting laboratory, Commander Pavel Vinogradov and Yurchikhin worked with the worked with the Bar experiment, which looks at methods and instruments for detecting the location of an air leak from one of the station’s modules.

Flight Engineer Alexander Misurkin conducted ocean photography for the Russian Seiner experiment, which examines Earth’s oceans to determine the current position and coordinates of bioproductive areas that impact the fishing industry.

Misurkin also conducted a session with the Uragan experiment. Named for the Russian word for hurricane, Uragan seeks to document and predict the development of natural and man-made disasters on Earth.
