The Expedition 36 crew members participated in biomedical experiments, prepared for an upcoming spacewalk and worked to maintain the systems aboard the International Space Station on Wednesday.

Flight Engineers Chris Cassidy, Karen Nyberg and Luca Parmitano used the Ultrasound 2 equipment to perform eye scans as part of the ongoing Ocular Heath study. The data collected was then downlinked for analysis by medical ground support teams to study the effect of microgravity on sight.

Nyberg and Parmitano also participated in the Reaction experiment, a short reaction time task that allows the crew and researchers to track the effects of fatigue on performance.

Cassidy performed some maintenance in the Destiny laboratory, removing and replacing the Rack Interface Controller in EXPRESS rack 7.

Parmatino participated in an in-flight interview with Italian TV network TG1, answering questions about his recent spacewalk, science and life aboard the station.

Throughout the week, Nyberg and Cassidy have been participating in robotics training to prepare for the grapple and berthing of the Japanese “Kounotori” H2 Transfer Vehicle-4 (HTV-4) set for August 9. HTV-4 is scheduled to launch on an H-IIB rocket Saturday at 3:48 p.m. EDT (4:48 a.m. Japan time on Sunday, Aug. 4) from the Japanese Space Agency’s Tanegashima Space Center in Southern Japan, beginning a week-long journey to the orbiting outpost.

Flight Engineers Alexander Misurkin and Fyodor Yurchikhin reviewed procedures and the timeline for their upcoming spacewalk, currently set for August 16. During the excursion, the duo will wear their Russian Orlan spacesuits and exit the Pirs docking compartment to route power cables from the Russian segment to the Zarya module. They will also continue the routing of an Ethernet cable from Zarya to the Poisk module in preparation for the arrival of the new Multipurpose Laboratory Module and set up another suite of experiments on the hull of the Poisk module.

Misurkin and Yurchikhin were later joined by Nyberg to gather spacewalking tools and equipment in advance of the upcoming spacewalk.

Commander Pavel Vinogradov worked on the transfer of supplies from the docked ISS Progress 52 resupply ship after opening its hatches for the first time on Sunday. The unpiloted Russian cargo ship docked to the station less than six hours after launch on Saturday with a payload of nearly three tons of supplies for the Expedition 36 crew. Included in the delivered cargo are tools for possible repairs to the U.S. spacesuits.

Misurkin worked with Cascade, a Russian experiment that investigates cultivation processes of micro-organism, animal and human cells in microgravity.  He, along with Yurchikhin and Vinogradov, also performed a variety of maintenance duties throughout the Russian segment of the station.
