The six Expedition 36 crew members living and working aboard the International Space Station were busy with biomedical experiments and a variety of spacewalk-related activities Wednesday as they continue to unload cargo delivered aboard the “Albert Einstein” Automated Transfer Vehicle-4.

Flight Engineers Chris Cassidy, Karen Nyberg and Luca Parmitano continued their participation in the Occular Heath study, performing eye tests using a Fundoscope. They also performed intraocular pressure measurements, or tonometry tests, as part of the Crew Health Maintenance System. The data collected was then downlinked for analysis by medical ground support teams to study the effect of microgravity on sight.

Cassidy and Nyberg also performed a scrub of the cooling loops on the U.S. spacesuits in the Quest airlock as preparations continue for a pair of spacewalks scheduled for July 9 and 16.

During the spacewalks, Cassidy and Parmitano are scheduled to replace a space-to-ground communications system and some wireless video equipment and install power cables for the upcoming Russian laboratory.

Parmitano was focused on the transfer of cargo from the European Space Agency’s Automated Transfer Vehicle-4 (ATV-4). Also known as the “Albert Einstein,” ATV-4 delivered 7.3 tons of science experiments and supplies for the crew when it docked with the station’s Zvezda service module on June 15.

After performing a successful spacewalk on Monday, Flight Engineers Fyodor Yurchikhin and Alexander Misurkin participated in a conference with Russian specialists to review the details of Monday’s excursion and to set the course for their next spacewalk together in mid-August.

Commander Pavel Vinogradov, Yurchikhin and Misurkin performed a variety of other post-spacewalk activities, including stowing equipment, performing leak checks and opening the hatch between the Zvezda service module and the ISS Progress 50 cargo craft to return the Russian segment to its pre-spacewalk configuration.
