MEDIA ADVISORY: M11-161
NASA TELEVISION TO BROADCAST SPACE STATION SPACEWALK
HOUSTON -- Two cosmonauts will conduct a six-hour spacewalk on
Wednesday, Aug. 3, to continue outfitting the Russian segment of the
International Space Station. NASA Television will broadcast the
spacewalk beginning at 9 a.m. CDT.
Expedition 28 Russian Flight Engineers Sergei Volkov and Alexander
Samokutyaev will install laser communications equipment and replace
experiments on the Zvezda service module. They also will retrieve a
rendezvous antenna, relocate a boom structure to aid future
spacewalks and deploy a small satellite equipped with an amateur
radio transmitter and a student-built experiment.
The duo will wear Russian Orlan spacesuits and will emerge from the
Pirs docking compartment airlock at about 9:30 a.m. The spacewalk
will be the third for Volkov, who performed two spacewalks as
Expedition 17 commander in 2008. This will be the first spacewalk for
Samokutyaev.

About two hours to go for this. Going to move to live events to give it some additional eyeballs and leave a mirror in the ISS section, given we normally host these in the ISS section.
Will want people to help out with this as there's big things happening in the world of Shuttle/SLS and everything inbetween today, apparently.
-
troubleshooting com caps, ISS feed still coming from the US lab
-
One of the cosmonauts are in their suit, but cant tell whom due to the feed.
Edit: Another still ingressing suit.
-
performing leak checks
-
From http://www.arrl.org/news/arissat-1-deployment-set-for-august-3-watch-live-via-computer-or-tv
According to the schedule, the hatch to the ISS will open at 1430, and just 16 minutes later, the cosmonauts will bring ARISSat-1 out and secure the airlock chamber. At 1452, the team will remove the satellite’s solar panel covers and at 1507, they will bring ARISSat-1 to the deploy site, activate the PWR, TIMER1 and TIMER2 switches, verify that the LEDs are on and deploy the satellite.

-
Hopefully the ISS feed will change to a truss camera soon.
-
Hatch is closed (think it is one from DC to SM)
-
NTV starting EVA coverage
-
Coverage starting, and Josh is PAO!
Edit: Jeff Williams is on Console

Awesome, we have NASA PAO Josh commentating.
-
Performing leak checks, should open hatch in about 8 minutes
-
CGI view of the DC
-
prebreathe complete
-
Pressure 101mm
-
ISS feed now on ISS truss thanks PAO!
-
Dropping external pressure and gradually increasing pressure in the Orlans.
Cosmonaughts are asked to report pressure every 30mm
-
O2 open to EVA, going to 12 mm
-
Reached 12 mm. Next check is at 5mm.
Counting down 5 min for a leak check
-
Not much KU coverage today as Josh stated
-
Too many voice feeds....
-
Too many voice feeds....
... and translators omitting a lot of phrases
-
Short drop off, regulators to O2 closed
-
Too many voice feeds....
Yeah. Big loop, Russian loop and the translator. All of it probably coming from the Russian feed, so not sure they can do much about it.
-
DC is at 11.5 mm pressure
-
opening hatch
Edit: hatch is open
-
installing protective ring, think camera is pointed at the wrong hatch, 21 minutes behind schedule
-
The hatch was opened at 9:50am Central time.
Running 20min behind schedule
-
EVA start 50 minutes past the hour - about 20 mins down.

GOing out to the EVA support device,a activating sublimator
-
Both cosmonauts were suits with blue stripes
-
What's the sublimator?
-
removing Radioskaf-V nanosatellite from airlock
-
View from Alexander's WVS
-
What's the sublimator?
From an interview - best way of explaining:
"In the backpack on each spacesuit, we have something called a sublimator. And you may recall from science, sublimation is a process by which ice will just evaporate directly into water vapor without melting. And so what we do in space is we allow ice to build up in the sublimator, which is exposed to vacuum, and then the particles of ice evaporate directly into space because of the zero pressure that the ice is exposed to. And that's how we reject heat from the spacesuit. "

Alexander is egressing the DC
Sergei's WVS is number 20, Alexander number 18

I keep expecting to see a helmetcam view of an orbiter docked :(
-
getting in position for Nanosat deploy

-
radioskaf has been activated
-
They always sound like they are arguing during Russian EVAs ;D
They are - kind of ;)
One says that he doesn't like this position, but the other one argues that he has just found a comfortable position
-
in position to jettison
-
verifying nanosat is in proper configuration before release
-
A question was raised about just one antenna attached to the satellite. Seems like there should be 2. Cosmonauts confirm that there was only 1 antenna.
-
Going to return the Radioskaf to the DC
Edit: due to concerns, going to leave it on the outside of the DC
-
The decision is: to turn all switches off (the ones that were just turned on) and return Radio-Skaf back into the hatch.
Cosmonauts are asked to be careful with the solar arrays.
Cosmonaut expresses opinion that it is better to launch it now. Otherwise during the next attempt there will be no solar arrays (implying they will be broken during all these transfers)
-
VIew inside DC

-
MCC Moscow asking crew to pause as they are still examining what to do with the radioskaf, might deploy it
Loss of KU
-
next task will be БТЛС-Н install, but crew waiting for Radioskaf-V plan

He could either be psychic or be a NSF checker.
-
CGI on the paths they are working.
-
Russian commentator is laughing about something! ;D
-
-
Connectors mated. Covers next.
-
-
Good news - telemetry shows that both connectors are well mated and are now active.
Only 10 min behind the schedule
-
MLI being moved. About to take some pictures
-
Eeek, Juno news conference on the media channel coming up, which is the only NTV channel working on VLC.
You might also try the Education Channel for that. Some indication that the news conference would be on that feed, too; it's working for me in WMP:

I have also a VLC playlist of the Public Channel stream for your desktop
-
Asking for photos with the cover open:
-
Cosmonaut: "Do you want us to take pictures?"
Ground: "Yes! Every cable connection operation ends up with taking photos of these connections"
-
guess I need to pull out my laser pointer the next time there is an ISS pass
-
-
Here's the unit they are working on:
-
A wingnut on a wrench has apparently "floated away".
-
LSP on twitter indicating now that the public feed will also show the Juno press conference
-
going to photograph, then jettison the MLI cover
-
MLi has been jettisoned, will continue cable work
Also, NTV public feed is going to stay with the EVA unlike previously indicated
-
Would it have been possible to deploy the radioskaf from the JEM airlock ???...I realize there is nothing currently to grapple on to with the Japanese RMS, but would it have been small enough to fit into the JEM airlock any ways ??...this is supposed to be the first of several of these satellites...maybe future ones can be deployed in this manner instead of an EVA ???

Too much structure that the pico sat could collide with in this attitude, also lack of a grappling mechanism.
-
Ground letting crew know that they started late, but have good working tempo.
-
crew now going to examine the troublesome Antenna
Edit: actually dont know which Antenna they are working on...
-
not going to mess with the first antenna, but will still take photos of the second
-
ku returns!
Per PAO, going to skip KU band antenna removal for now due to timeline, still working laser communications device install
-
setting up to take images of the degraded antenna

MCC-M letting crew know what not to grab
-
Sergei has taken pictures, will swap cameras and wratchet wrenches
-
ok, why does the ISS feed always switch to the side that does not show the crew?
-
having issues translating, trying to figure out how to proceed, reel was about a meter short
-
ground asking crew to stop to try to figure out how to help
-
going to remove cable holder to add length
-
anyone want to take over?

anyone want to take over?
Here ;)
-
working connector cap, what camera is the second picture?
-
Are they still working wires of laser communications system?
-
And that connector is done.
-
Telementry confirms.
-
There's that "one, or should it be two antennas" ARISSat-1
-
Looks like they are going to launch it after all!
-
Not going to remove the Kurs antenna. Want to stay within a nominal EVA length.
Strela relocate - big task - will take three hours.
-
last from me, but it is a camera view from Cupola on the ISS feed
-
working connector cap, what camera is the second picture?
Maybe it was from Cupola, like the view we had just couple seconds ago..
-
They are at the Strela arms, but launch of ARISSat-1 is coming up shortly.
-
Starting with Strela 2.
-
Don't kick the Progress ;)
-
Interesting note from Josh, this view is coming from a camera set up by Mike Fossum in the Cupola.
-
No Ku - lots of fun with this task.
-
Off for a ride!
-
On ARISSat-1, they think the second antenna may be stuck inside the satellite, or it might of broken off, but they are going to deploy it.
-
Josh confirming they think it's damaged - antenna's broken off. Hope their kept their reciept.
-
Got to jettison before the eclipse. 3 minutes!
-
It's on its way. 1:43pm Central.
No Ku.
-
ARISSat-1 deploy! Yay!
Lets see if we get any signals when they pass overhead later.
-
No Ku.
And likely no UHF from the sat without the antenna.
-
Wow! Defer Strela relocation.
So this is just down to photos of the Russian version of the MISSE. Will now remove Kurs antenna. Install a bio container.

I've just lost track what they have actually done.. A lot of changes!
-
Hopefully the VHF side will still work.
-
Which antenna is missing the UHF receive or the VHF transmit
If it's the VHF transmit then the sat is useless
-
Ok, I think we're up to date - as to where we are now - with Pete's article:
http://www.nasaspaceflight.com/2011/08/cosmonauts-russian-spacewalk-international-space-station/
-

Looks like its the UHF antenna, according to comments on ISS Fan Club. So we may still hear some activity on the 2m band.
-
Lets hope so!!!
-
4hrs 10mins PET - so you can see why they had no chance of completing the 3hr Strela task.
-
Sergei sounds downbeat about this all. MCC-M noting they feel his pain.
-
I wonder whether they'll add another EVA to relocate Strela - if so, this might not be the last EVA of this year.
-
Should be getting Ku back soon.
-
Here we are:
-
The ARISSat-1 problem will result in degraded receive capability only.
-
Kurs antenna removed.
-
Technically one hour remaining on the EVA.
-
ARISSat-1 has a UHF to VHF transponder that would allow amateur radio operators to talk with each other. Without a UHF antenna this side of the bird is unlikely to function. It should still be able to transmit VHF-side recorded messages, telemetry, and slow-scan TV (SSTV) images.
Ground station control was probably through the UHF side as well. It's likely that is lost or at best iffy.
-
Now in the location of the Komplast.
Loving the translator!
"Be careful with your tethers"
"I know, but they are sooooo loooong" - it's the way he's translating it ;D
-
-
There's the Komplast in question.
-
Going to take some photos to see how the different materials are performing.
-
Photos from the side.
-
Biorisk containers next. 15 min task.
-
15 mins of LOS coming up
-
LOS happens in the middle of a conversation, oops.
-
Another 40 mins without Ku. 10 more for LOS.
-
Currently putting the removed Kurs antenna into the airlock. Will be taken inside of station with them at the conclusion of the EVA.
-
Site of use:
http://www.arissat1.org/v3/
-
Here's the Biorisk experiment they are working on.
Next to last task.
Photos will wrap up the EVA.
-
FD Emily Nelson and FD Royce Renfrew - both known to frequent this very site at times :)
-
Holding for about 10 minutes to sunrise to start the final task of the EVA - to take some photos.
-
They will be photographing pictures of influential Russian space figures Yuri Gagarin, Sergei Korolev, and Konstantin Tsiolkovski floating in the vacuum of space.
-
Ku is back. Taking photos of the legends.
-
They are taking them from within the airlock.
-
Here you can see one of the portraits...
-
And another...
-
Job done!
Go to ingress. I think I captured Korolev:
-
Alexander Samokutyaev joining Sergei Volkov in the airlock.
-
Tool inventory. EVA will conclude at hatch closure (Russian EVA end point).
-
Go to complete hatch closure.
-
Hatch closed. 4:13pm Central time.
EVA lasted 6hrs and 23mins.
-
Josh with some stats:
161 EVAs for ISS. Total time 1,015 hours and 32 minutes.
Ex-28 now has two EVAs, the other out of Quest during 135.
-
This is the task we lost:
-
Josh signing off, he was great as per usual.

As was the coverage from this site. Thanks to all who contributed!
-
Kind of sad that the main reason for the EVA was not accomplished, how long until another? Wouldn't be surprised if there was a second EVA before the end of the year. This EVA was definitely a uphill battle today.
Also, why didnt they start out with the Strela relocation, and done the other activities later? Seems like a USOS would have prioritized the major task first, like the PM return/RRM retrieval.

:o! ;)
Pete's article...
"The next spacewalk (RS EVA-30) is currently scheduled to be conducted sometime in February 2012 – meaning that this EVA will be the last scheduled EVA of 2011, and the last scheduled EVA for six months."

I did know that the next scheduled EVA was next year, was just speculating that MCC-Moscow might add another just to do the Strela work since this crew is already trained to do it, which was the reason for the "how long until another" comment.

Maybe there is an unscheduled Russian EVA-29A later this year.

ARISSat-1 downlink appears to be working, as at least 13 HAMs have now reported hearing it. No report that the uplink/transponder is working, as to be expected with the missing uplink UHF antenna.

The article didn't make clear why there is any limit on how many spacewalks they can do. Why not just do another one in a few days to finish the work?

Two reasons:
- Crew time to rest and then prep for the EVA
- Russia flies a Progress vehicle to replenish the air that is vented overboard. Doing another EVA right now would mess with the long-term consumables planning.

Sergei Volkov and Oleg Kononenko had to conduct an unscheduled EVA on Expedition 17 to remove a pyrobolt from their Soyuz, then conducted another EVA five days later.
-
Has it been published which Orlan-MK suits were used for the EVA (e.g. Orlan-MK #4 and 5)?
-

I think the Orlan MK suits used were #4 and #6 (both blue stripes), but I can't find who used each one.
Suit #5 has red stripes.

Hammin’ It Up
A satellite with amateur radio capabilities and a student-designed experiment was released into orbit around Earth on Aug. 3, 2011, during a spacewalk outside the International Space Station. The satellite is transmitting signals containing information that students around the world can access.
The Amateur Radio on the International Space Station Satellite-1, or ARISSat-1, is a follow-on project to the unique SuitSat-1. SuitSat-1 was an amateur radio transmitter fitted into a surplus Russian Orlan spacesuit that was released from the station into space in 2006. SuitSat-1 transmitted for about two weeks and orbited Earth for seven months before burning up in Earth’s atmosphere.
Formerly known as SuitSat-2 and also called Radioskaf-V and Kedr by the project’s Russian partners, ARISSat-1 contains a student-designed experiment and other equipment that students can use to learn more about space and space exploration. ("Kedr," which is Russian for "Cedar" in English, was the call sign of Yuri Gagarin, a Russian cosmonaut and the first human in space.)
ARISSat-1 is a project by the Radio Amateur Satellite Corporation, or AMSAT, and affiliated with the Amateur Radio on the International Space Station. ARISS is an education activity where space station astronauts and cosmonauts use amateur radio equipment aboard the space station to talk with students around the world.
The development, launch and deployment of ARISSat-1 are being conducted as an educational mission with the support of the NASA Office of Education’s ISS National Lab Education Project and RSC-Energia. It is the first of a series of educational satellites planned for deployment from the space station. Future satellites will carry additional student-built experiments, which will have data sent to the ground via amateur radio signals.
AMSAT ARISSat-1 project manager Gould Smith said the educational mission of the project is to use the unique aspects of satellites and amateur radio transmissions to generate student interest in space, science, technology, engineering and mathematics.
ARISSat-1 traveled to the space station in late January aboard a Russian Progress cargo vehicle and was released into space during a spacewalk by Russian cosmonauts Sergei Volkov and Alexander Samokutyaev.
For ARISSat-1, the onboard experiment is from Kursk State Technical University in Kursk, Russia. The experiment is going to measure the vacuum in space at different altitudes as the satellite’s orbit decays, gathering 90 minutes of data each day and transmitting that data continuously back to Earth. By analyzing these data, student scientists can derive atmospheric density from in situ measurements. These data in turn can be used to better predict the orbital lifetime of ARISSat-1.
Originally designed -- like its predecessor -- to fit inside an Orlan spacesuit, ARISSat-1 was redesigned when the expired spacesuit allocated for the project was disposed of sooner than AMSAT could use it. The redesign actually turned out to be a good move for the project, project managers said, because it allowed capabilities to be expanded.
The rectangular spacecraft is covered by six solar panels that will charge the batteries in the satellite for about six months as it orbits Earth. Spoken telemetry values, with data such as temperature and battery life, are intended to promote science and mathematics education by encouraging schoolchildren to listen to the satellite, track its progress and plot the changes. AMSAT president Barry Baines said it’s a great opportunity for students to do actual science, by taking real-time, practical readings on a daily basis and plotting the changes. The telemetry data will be available live and over the Internet for schools and radio amateurs to study the operation and changes that the satellite experiences during its orbits around Earth.
The project website provides free downloadable software that can be used to decode the data. "They can look at all the values, but you can also get the Russian experiment data at the same time and actually look at that every day," Baines said. "Plus, that data will be stored online, and they will be able to access it via the Internet to be able to go back and look at historical data or just use it in a lesson to actually take the real data and analyze it."
"The most useful, exciting and effective element of learning in regards to this project is actually doing something hands-on and practical, rather than just sitting and listening to a lecture. If you can actually go out and collect the data and then do something with it, that’s a lesson that’s learned and understood at higher cognitive levels."
In addition to data, the satellite will transmit 24 pre-recorded greetings in 15 different languages -- French, Spanish, German, English and Chinese, to name a few. More than half of the messages were recorded by schoolchildren, Smith said. "Most of them are really creative and interesting to listen to, especially male and female voices, and even kind of a little rap by the Dutch group. Also, most of them have a secret word at the end, and there’s a contest: If you can identify the secret word and send an e-mail, we’ll return an e-mail back to you with a little certificate."
Attached to the inside of the satellite is a memory card containing images and documents from children around the world. A website has been set up to view the files on the card. There is also a contest to see who correctly copies the most Morse Code signals sent by ARISSat-1. The signals will consist of the call signs of all amateur radio operators who worked on the project. Additionally, still images of Earth will be transmitted from four cameras aboard the satellite. ARISSat-1 also will serve as an orbital communications relay station for use by amateur radio operators around the world. The ARISSat-1 website lists all of the ARISSat-1 contests and challenges.
Helping with the project is NASA retiree Lou McFadin. McFadin has been closely involved with amateur radio and human spaceflight through the Shuttle Amateur Radio Experiment, or SAREX, project, beginning with astronaut Owen Garriott’s first amateur radio communications on the STS-9 shuttle mission in 1983. McFadin is the ARISS hardware manager and has worked with the development of the ARISSat-1 hardware since the start of the project.
"I think if they (students) do the telemetry decode," McFadin said, "there’s a lot of opportunity for learning there. It has solar panel temperatures; it has solar panel data; it has battery voltage and all kinds of information there about what’s going on in the satellite. That kind of learning really connects to our goal of getting children and all Americans interested in space. That’s a big part of what we wanted to do."
ARISSat-1 also will serve as a technology demonstration. "For AMSAT, it certainly was a way to try out some new ideas -- how to build the structure for the dynamics of the satellite itself, it’s a new power system, it’s a new transponder system we’ve not tried before, it’s the first time we’ve flown a software-defined transponder, and it’s paving the path for the future for us," Smith said.
McFadin said the software-defined transponder was the key to how they were able to design a satellite to do so many things at once. "It’s an FM transmitter, it’s a transponder, it’s a telemetry transmitter, and Morse code transmitter, all done with one system, all simultaneously," McFadin said. "We’ve never been able to do that before."
This was AMSAT’s second opportunity to release a satellite from the International Space Station, and Smith said they hope to continue the project with future spacecraft and more student-designed experiments. "It’s not any harder to build four of something than it is to build one, hardly. So we built four space frames, five actually, one for the prototype, and we built four flight versions," Smith said. "So it’ll be easy to do this again."
Mark Severance, manager for the ISS National Laboratory Education Project, sees ARISSat-1 as an important flight test for future educational satellites. "Future ARISSats will carry at least four student-designed and -built experiments," Severance noted. "This will give students the opportunity to go hands-on and build actual spaceflight experiment hardware. Furthermore, they can track the satellite using off-the-shelf amateur radio hardware and obtain the data from their experiment directly from their own ground station. In this manner, ARISSat can provide an 'end-to-end' space mission experience for participating students."
NASA's Office of Education's ISS National Laboratory Project will sponsor future ARISSats. The project provides hands-on opportunities for elementary, secondary and university students, as well as lifelong learners, to participate in the space station mission. The ARISS school contact activity is supported by the ISS National Laboratory Project as well as the Teaching From Space Office at NASA's Johnson Space Center in Houston. Teaching From Space facilitates education opportunities like ARISS that use the unique environment of space to increase student interest in science, technology, engineering and mathematics.

No, there are 2 Soyuz and 2 Progress spacecraft.

Has it been published which Orlan-MK suits were used for the EVA (e.g. Orlan-MK #4 and 5)?
I think the Orlan MK suits used were #4 and #6 (both blue stripes), but I can't find who used each one.
Suit #5 has red stripes.
If you look to the Hi-res of this photo ( http://spaceflight.nasa.gov/gallery/images/station/crew-28/html/iss028e020805.html (http://spaceflight.nasa.gov/gallery/images/station/crew-28/html/iss028e020805.html) ) you will see that Volkov is wearing Orlan MK #4

On this (http://spaceflight.nasa.gov/gallery/images/station/crew-28/html/iss028e020581.html) picture, the number "MK n°6" is clearly visible.

I was told Sergey Volkov has used Orlan-MK #4, Aleksandr Samokutyaev - #6.
