The investigation continues into the cause of a spacesuit water leak that occurred during last week’s spacewalk. Meanwhile, the Expedition 36 crew is preparing for the launch of two new resupply ships over seven days.

Flight Engineer Karen Nyberg joined Flight Engineer Chris Cassidy for troubleshooting work on a leaky spacesuit that ended a July 16 spacewalk. Ground teams have been working in conjunction with the crew to review possible evidence to identify the cause. Spacesuit tools have been shipped to Russia for launch aboard a new ISS Progress 50 (50P) resupply ship Saturday at 4:45 p.m. EDT with docking scheduled about six hours later.

After assisting Cassidy, Nyberg worked on numerous science and maintenance tasks. She checked out an Earth observation experiment, ISERV, observing the payload during ground commanding. She also printed new rack labels and conducted an inventory of contents inside the Unity node. Finally, Nyberg checked out and activated gear to assist in the approach and rendezvous of the H-II Transfer Vehicle-4 (HTV-4) from the Japan Aerospace Exploration Agency. The HTV-4 is scheduled for launch from the Tanegashima Space Center in Japan Aug. 3.

Flight Engineer Luca Parmitano partnered with Ames Research Center engineers to remotely control a surface rover in California from the space station. The experiment, called Surface Telerobotics, will help scientists plan future missions where a robotic rover could prepare a site on a moon or a planet for a crew.

While performing some minor work Friday, the three cosmonauts had an off duty day. The trio will be working Saturday monitoring the arrival of the 50P.

Commander Pavel Vinogradov started Friday morning with housekeeping tasks checking ventilation systems, inspecting an air conditioner and cleaning laptop computers. Later he joined Flight Engineers Alexander Misurkin and Fyodor Yurchikhin installing thermostats for several ongoing Russian experiments.

Throughout the day, Misurkin and Yurchikhin worked on a variety of science experiments that included studying bacteria, measuring vibrations outside the station and photographing and videotaping the Earth below.
