Veteran Russian Cosmonauts Set for Spacewalk on NASA TV
WASHINGTON, NASA Television will broadcast live coverage of a six-hour spacewalk by two Russian crew members aboard the International Space Station beginning at 9:45 a.m. EDT Monday, Aug. 10.
Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency (Roscosmos) will don their spacesuits and exit the station's Pirs airlock at 10:14 a.m. Their objectives are to rig new equipment on the Russian segment of the station and conduct a detailed photographic inspection of the exterior of the orbiting outpost.
Padalka and Kornienko will install devices called gap spanners on the hull of the station. These devices will facilitate the movement of crew members on future spacewalks. They also will clean residue off of the windows of the Zvezda Service Module, install fasteners on communications antennas, replace an aging antenna used for the rendezvous and docking of visiting vehicles at Russian docking ports, and photograph a variety of locations and hardware on Zvezda and nearby modules.
The pair also will retrieve an experiment first deployed in 2013, the Obstanovka Experiment, which studies the interaction between the space station and the space plasma environment in low-Earth orbit, as it can affect power supply systems and other external surfaces.
The spacewalk will be the 188th in support of space station assembly and maintenance, and the 10th spacewalk for Padalka, who has spent more time in space than any other human. It will be the second spacewalk for Kornienko, who is in the fifth month of a one-year mission on the complex.
Padalka will be designated extravehicular crew member 1 (EV1) and Kornienko will be extravehicular crew member 2 (EV2). Both will wear Russian Orlan spacesuits bearing blue stripes.

Russian cosmonauts to go on first spacewalk this year
the walk will last over six hours
Russian spacemen Gennady Padalka and Mikhail Korniyenko will leave the International Space Station (ISS) for six and half hours on Monday to work in outer space, The Russian Federal Space Agency (Roscosmos) has told TASS.
"The spacewalk will begin at 17:14 Moscow Time and will continue until 23:48 Moscow Time," a source in the space agency said.
Gennady Padalka has walked into space eight times, with his spacewalks lasting a total of 33 hours and 4 minutes , while Mikhail Korniyenko did one spacewalk, having spent 6 hours and 43 minutes in outer space.
During the two cosmonauts’ spacewalk on Monday, Russian cosmonaut Oleg Kononenko, US astronauts Scott Kelly and Chell Lindgren and Japanese astronaut Kimiya Yui will be waiting for their return at the International Space Station.

RS-41: Cosmonaut duo set for the only Russian spacewalk of 2015
While the astronauts in the US segment of the International Space Station (ISS) are working on returning their spacesuits to full service, the Russian segment is preparing for another, somewhat routine, extravehicular activity (EVA). RS EVA-41 will be the only Russian spacewalk of 2015 – set to begin shortly after 10 a.m. Eastern on Monday.Among the objectives of the spacewalk, designated RS-41, are the installation of gap spanners, maintenance of antennas used for communication with visiting vehicles, cleaning of a window, and science experiment work.
The spacewalk is scheduled to begin on Monday, August 10, at 14:14 UTC (10:14 a.m. Eastern) – although this is subject to change, based on the timeline of their EVA preparations – with cosmonauts Gennady Padalka and Mikhail Kornienko egressing the Pirs airlock.
Padalka will be EV-1 wearing an Orlan spacesuit with blue stripes. Kornienko will be EV-2, also with blue stripes.
Their first task is to install a gap spanner between two handrails on the Service Module (Zvezda). This installation is planned for just five minutes, as the two handrails are very close to each other.
Gap spanners, literally translated from Russian as soft handrails, are straps that connect handrails on the hull of the station. Cosmonauts use the gap spanners to translate past various obstacles more easily.
Then, the spacewalkers will move to window No.2 on Plane IV of the Service Module, and clean the window from rocket engine exhaust that deposits on the exterior of the station as visiting spacecraft arrive and leave.
After the cleaning, the pair of cosmonauts will translate along a series of handrails to the WAL1, WAL2, and WAL3 antennas, which serve communication between the Russian segment and approaching and departing visiting vehicles.
.
They will install fasteners on all three of these antennas. The fasteners are designed to prevent the antenna covers from inadvertently coming off – an issue observed back in August 2013.
This task will be followed by a visual check of their spacesuits, glove cleaning, and jettisoning of used towels.
The next activity on the EVA timeline is photography of the Expose-R experiment.
The experiment examines how microgravity and the conditions outside the ISS affect different biological samples.
The pictures taken will reveal to investigators whether there has been any change to the materials involved with this experiment.
Another experiment that the cosmonauts will work with is the Obstanovka experiment, which investigates plasma wave processes in the vicinity of the ISS.
Commander Padalka will dismantle a sensor unit and stow it in his crew lock bag to bring the sensor inside the station towards the end of the spacewalk.
Next up will be the installation of another gap spanner and sampling of a radiator panel surface as part of the Test experiment.
More sampling will take place near the Russian environmental and life support systems overboard vents. The systems sampled will be Vozdukh (carbon dioxide scrubbing) and Elektron (oxygen generation).
After the sampling, the cosmonaut duo will return back to the airlock and stow their crew lock bag which by then will contain the sensor unit from Obstanovka and the used sampling kits. They will retrieve more equipment related to the antenna work and also a brand new antenna to replace the WAL6 antenna.
.
Next, the EVA crew will install fasteners on the WAL4 antenna.
The final antenna maintenance task is to cut off cabling from the WAL6 antenna, remove the antenna and install its replacement. After they route and connect all the necessary cables for the new antenna, the two will head back to the airlock and jettison the old antenna.
Finally, the spacewalkers will translate to the Poisk module, where they will reposition BKDO, a piece of equipment which measures rocket engine plume impingements on the station’s hull.
Then, they will head back to the airlock to wrap up the EVA. The total duration of the excursion is planned to be 6 hours 28 minutes.

International Space Station Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency began a planned approximately 6-hour spacewalk from the Earth-facing Pirs Docking Compartment at 10:20 a.m. EDT.
Padalka will be designated extravehicular crew member 1 (EV1) and Kornienko will be extravehicular crew member 2 (EV2). Both will wear Russian Orlan spacesuits bearing blue stripes. Their suits are equipped with NASA helmet cameras to provide close-up views of the work they are performing outside the station.
This is the 188th spacewalk in support of space station assembly and maintenance.
The spacewalking duo will install devices called gap spanners on the hull of the station that will facilitate the movement of crew members on future spacewalks. They also will clean residue off of the windows of the Zvezda Service Module, install fasteners on communications antennas, replace an aging antenna used for the rendezvous and docking of visiting vehicles at Russian docking ports, and photograph a variety of locations and hardware on Zvezda and nearby modules. An experiment designed to measure the space environment first deployed in 2013 will be retrieved and brought inside for its return to Earth.
Flight controllers at the Russian Mission Control Center in Korolev, outside of Moscow, are providing primary support for the spacewalk and coordinating with Mission Control at NASA’s Johnson Space Center in Houston.

Russian astronauts go on spacewalk to clean windows and upgrade station
Astronauts filmed five-and-a-half-hour walk on hand-held cameras and kept in touch constantly with each other and Russian mission control near Moscow
Two Russian cosmonauts added new equipment outside the International Space Station on Monday and took pictures to study its exterior during a five-and-a-half-hour spacewalk.
The outing was the 188th in support of the space station and the 10th of Gennady Padalka’s career, a veteran cosmonaut and grandfather who is serving as commander of the space station.
In June, Padalka, 57, set the world record for the most time spent in space: a total of 803 days.
His spacewalking partner, Mikhail Kornienko, 55, undertook his second walkabout in space.
Hours into the rigorous spacewalk, Padalka and Kornienko playfully taunted each other over whose hands were coldest and who had the most spirit, live footage broadcast on the websites of the Russian and US space agencies showed.
The spacewalk was over at 1951 GMT, an hour ahead of schedule. It lasted five hours and 31 minutes, NASA said.
Padalka and Kornienko installed gap spanners on the hull of the station to help “facilitate the movement of crew members on future spacewalks”, NASA said.
They also cleaned windows, installed fasteners on communications antennas, replaced an ageing antenna used for rendezvous and docking visiting vehicles at Russian docking ports, and took pictures of locations and hardware on Zvezda and nearby modules.
Floating against the bright blue oceans and white clouds of Earth, the astronauts filmed the outing with small hand-held cameras, constantly communicating with each other and Russian mission control outside Moscow.
Once they get out of their spacesuits, they will be able to sample their first bites of space-grown red romaine lettuce that their colleagues have saved for them.
Two US and one Japanese astronaut tasted the lettuce earlier on Monday.
NASA astronaut Kjell Lindgren described the leafy greens as “awesome”.
Scott Kelly, who is spending one year aboard the space station with Kornienko, said the leaf tasted a bit like arugula.
The ability to cultivate food during a trip to Mars in the coming decades will be key to surviving the trip, which could last months or years.
“This payload, and having the ability for us to grow our own food, is a big step in that direction,” Kelly said.
The next spacewalk around the Russian section is set for January or February 2016, a space industry official, Alexander Kaleri, told the news agency Tass on Monday.
