Russian Spacewalkers to Move Cargo Boom, Deploy Ham Radio Satellite
Two Russian cosmonauts will leave the confines of the International Space Station on Aug.3 to move a cargo boom from one airlock to another, install a prototype laser communications system and deploy an amateur radio micro-satellite.
Expedition 28 Flight Engineers Sergei Volkov and Alexander Samokutyaev are scheduled to venture outside the Pirs airlock at 10:30 a.m. EDT Wednesday to begin the six-hour excursion. Both spacewalkers will wear Russian Orlan-MK spacesuits. Coverage of the spacewalk will be broadcast live on NASA Television beginning at 10 a.m. EDT.
Volkov, making his third spacewalk, and Samokutyaev, making his first, will both wear spacesuits marked with blue stripes. Volkov's previous two spacewalks occurred while he was Expedition 17 commander in 2008.
During the spacewalk, Commander Andrey Borisenko and NASA Flight Engineer Ron Garan will close the hatches on the Poisk docking module, which is opposite the Pirs airlock, and seal the hatches between Zvezda and Poisk.
This gives them access to their Soyuz 26 spacecraft, protects against the unlikely possibility of a sudden station depressurization and allows the forward transfer compartment of Zvezda to be used as a backup airlock.
Flight Engineers Mike Fossum of NASA, and Satoshi Furukawa of the Japan Aerospace Exploration Agency, will be in the U.S. segment and will have access to their Soyuz 27 spacecraft, which is docked to the Rassvet module.
The duo's first task will be to deploy a boxy, 57-pound satellite, called alternately ARISSat-1 and Radioskaf-V, which is the prototype test flight of a proposed series of educational satellites being developed in a partnership with the Radio Amateur Satellite Corp. (AMSAT), the NASA Office of Education ISS National Lab Project, the Amateur Radio on ISS (ARISS) working group and RSC-Energia.
The ARISSat design can carry up to four student experiments and the data from these experiments will be transmitted to the ground via an amateur radio link. This prototype ARISSat-1 carries one student experiment, a pressure sensor built at Kursk University in Russia, to measure atmospheric pressure for the lifetime of the satellite.
