Expedition 36 Flight Engineers Fyodor Yurchikhin and Alexander
Misurkin closed the Pirs docking compartment hatch officially ending
their spacewalk at 6:05 p.m. EDT. The duo rigged cables for the future
arrival of a Russian laboratory module and installed an experiment
panel.
Clad in Russian Orlan spacesuits, the spacewalkers began their spacewalk at a revised time of 10:36 a.m. They first set up a Strela cargo boom on the Poisk mini-research module. Misurkin then used the Strela to maneuver Yurchikhin with cables to the Zarya module near the Unity node. Yurchikhin then rerouted a cable connector and installed cables on Zarya.
While Yurchikhin was working on Zarya, Misurkin installed an experiment panel on Poisk. The experiment, named Vinoslivost, exposes materials to the space environment so scientists can study the changes in their properties. He then installed two connector patch panels and gap spanners on Poisk.
After completing the Poisk work Misurkin joined Yurchikhin and assisted him with the Ethernet cable installation work on the Zarya cargo module. The duo went back and forth between Zarya and Poisk routing and installing the cable at various points and securing the cable’s slack.
The cable work outside the station’s Russian segment prepares the orbital laboratory for the arrival of the “Nauka” Multipurpose Laboratory Module. The “Nauka” is planned for a launch atop a Russian Proton rocket to replace Pirs.
For the duration of the spacewalk, station Commander Pavel Vinogradov and Flight Engineer Chris Cassidy were isolated to the Poisk module and their Soyuz TMA-08M spacecraft while Flight Engineers Karen Nyberg of NASA and Luca Parmitano of the European Space Agency moved about the U.S. segment of the complex.
The spacewalk is the 172nd in support of station assembly and maintenance, the seventh in Yurchikhin’s career and the second for Misurkin. The two will venture outside Pirs again on Aug. 22 to replace a laser communications experiment with a platform upon which a small optical telescope will be mounted during a future spacewalk.

NASA Exercises Expendable Launch Vehicle Contract Option
NASA
has exercised the first option on a contract providing integrated
services for the preparation and launch of the next generation of the
agency's scientific and exploration spacecraft.
The two-year Option Period 1 on the Expendable Launch Vehicle
Integrated Support (ELVIS) 2 contract, operated by a.i. solutions Inc.
of Lanham, Md., begins Oct. 1 and is valued at about $56.5 million. The
contract contains another potential option period that would begin in
October 2015, if exercised.
The ELVIS 2 contract began in April 2012 and has a potential maximum
value of $138.1 million. This contract resulted from a competitive small
business set-aside.
The ELVIS 2 contract supports NASA's Launch Services Program (LSP)
and LSP-sponsored missions, activities and strategic initiatives for
multiple NASA programs, the Defense Department and other government
agencies and commercial launch activities. The contractor will support
program management; vehicle engineering and analysis; launch site
engineering; communications and telemetry; technical integration
services; LSP programmatic safety, reliability and quality assurance;
LSP operations at Vandenberg Air Force Base in California; information
technology; and special studies.
