Author Topic: RS EVA VKD-59 - Experiment retrieval and comms - June 22nd [Prokopiev, Petelin]  (Read 10812 times)

Offline eeergo

Coming up tomorrow, cosmonauts Petelin and Prokopiev will perform VKD-59 dedicated to maintenance and experiment retrieval ("retrieve several experiment packages and install communications equipment" according to NASA).

The previously planned activities to activate the ShK airlock seem to have been deferred to VKD-60 or subsequent.

comms reconfigured wih SG1 and 2 dedicated to the EVA.  SG3 and 4 for ISS related comms.  Russian traffic on the ISS Youtube feed, no translations. The only times Russian comms are on this channel is during EVAs or Russian vehicle arrivals/departures.

Prokopiev and Petelin are preparing to open the Poisk MRM2 hatch. No station video at the moment, we're just getting the feed from Moscow mission control.

Offline Yellowstone10

Hatch is now open! (Official start time is 1424 UTC.)

LIVE: Two cosmonauts are stepping outside the @Space_Station to install equipment and retrieve experiments. Today's spacewalk is scheduled to start around 10:20am ET (1420 UTC) and last up to seven hours—follow along at nasa.gov/live.

Offline Yellowstone10

Petelin is the cosmonaut who's currently out the hatch with some sort of cable reel. He's on his 5th spacewalk. (Also, there's a little circular cover on the Zvezda node that opened - wonder what that is?)

Both cosmonauts now outside the airlock.

Some early helmetcam views as the cosmonauts work to demate cables connected to the science experiment equipment that will be jettisoned during the spacewalk.

Offline Yellowstone10

Now routing cables along Zvezda that will connect to a new data transmission radio to be installed later in the spacewalk.

Offline Yellowstone10

A helmet cam view (on the right) of the new data transmission radio monoblock that will be installed during the spacewalk.

Edit - and a good view of the zenith side of Zvezda.

Getting some imagery of connectors on the zenith side of Zvezda that had been covered under some MLI. (Sounds like there was some question as to the current configuration?)

Side note - anyone remember the name of this experiment attached to the starboard side of Zvezda?

Offline Yellowstone10

Continuing to route cables rearward along the Zenith side of Zvezda. The spacewalkers have been asked to take a brief break while ground controllers rotate the solar panels to provide clearance for removing equipment that will be jettisoned later in the spacewalk.

I think the objects to be removed are:

Seismoprognoz experiment
SVPI  monoblok
TM/TS monoblock

I wish NASA PAO would use these names in parentheses so we could know what they are removing right now!

Pretty big paint chip liberated off the handrails there as they prepare to mount the new data transmission unit.

Getting ready to mate cables to the new data transmission unit.
« Last Edit: 06/22/2023 05:15 pm by Yellowstone10 »

Offline Yellowstone10

All four cables have been mated to the new data transmission unit. (Also the Russian approach of just sewing on fabric tape to serve as the labels on the MLI is charmingly low-tech.)

Offline Yellowstone10

In true Hitchhiker's Guide to the Galaxy fashion, this cosmonaut knows where his towel is. (It's attached to the crew lock bag.)

Offline Yellowstone10

Nice view of the new antenna group on the left, Petelin (?) in the middle, and one of the other exterior experiments (whose name I can't recall) on the right.

Offline Yellowstone10

Protective shrouds removed from the new antenna unit.

Offline Yellowstone10

Interesting to spot the old RKA logo there on Zvezda. Also, Progress MS-22 there at the back.

Offline Yellowstone10

Prokopiev has installed a cover on an Impact scientific experiment and removed it from Zvezda to be returned inside the station.

Offline Yellowstone10

A wide-angle view showing Petelin and the new antenna unit, with what looks like the world's tiniest SASAs on it...

Offline Yellowstone10

Experiment cassette removed from the rear face of Zvezda and bagged up for retrieval inside the station.

Taking imagery of the Lira antenna boom.

I don't have audio at the moment (I might be watching this in the middle of a Zoom meeting...), but it looks like they're cleaning up and heading forward towards the airlock.

Offline Yellowstone10

Window cleaning task underway.

Offline Yellowstone10

Hah, I think Prokopiev is posing for photos taken by Fedyaev through the window they just cleaned.

Pretty cool view down at Nauka and the Earth as the cosmonauts inspect their spacesuits for contamination.

Prokopiev back at the Poisk airlock.

(Edit - not retrieving Biorisk quite yet as of this picture)

Good view into the airlock as they work to stow the samples they retrieved during today's spacewalk.

Offline Yellowstone10

Now in a ~10 minute video LOS, but they are working their way up to the Biorisk containers of biological samples that have been exposed to the vacuum of space, and will be retrieving one container.

Offline Yellowstone10

Voice reacquired. The cosmonauts are inside the airlock and taking steps to prepare to close the hatch.

Offline Yellowstone10

Video's back, but not much to see as the cosmonauts are inside Poisk at the moment.

Offline Yellowstone10

Timer at MCC Moscow stopped at 06:23:57 elapsed time, 20:48:30 UTC, presumably at the moment of hatch closure.

Closing remarks delivered as repress gets underway.

A few history items regarding experiments removed on today's spacewalk:

 - The Biorisk-MSN experiment was installed during VKD-50, 9 September 2021, with 3 canisters to be removed and returned at various intervals - https://forum.nasaspaceflight.com/index.php?topic=54471.0
 - Impakt was installed on VKD-43, 17 August 2017 - https://forum.nasaspaceflight.com/index.php?topic=43558.0 Correction: as pointed out by Nicholas Pillet, that was the first Impakt tray. The one retrieved on this spacewalk was the second, which was installed during VKD-47, 18 November 2020.
 - Seismoprognoz was installed during VKD-37, 27 December 2013 - https://forum.nasaspaceflight.com/index.php?topic=33530.0
 - SVPI was installed during VKD-27, 21 January 2011 - https://forum.nasaspaceflight.com/index.php?topic=21500.180 - back when all our screenshots were 240p...
 - TM/TC was installed - I think - during VKD-12, 26 January 2005 - https://spaceref.com/status-report/nasa-space-station-status-report-26-january-2005/ (It seems to have originally been part of a DLR robotics experiment called ROKVISS that was removed in 2010.)
 - The SKK #4-SM cassette that was removed off the aft end of Zvezda was installed during VKD-10, all the way back on 3 August 2004! - https://twitter.com/Kosmo_Michal/status/1671836821603381248

My records indicate TM/TS was launched on Progress M-51 and installed on 2005 Jan 26. It was relocated on 2014 Jun 19 from the
MPAC/SEED carrier frame to the 'Perokhodnaya ramka' boom 17KS.600Yu1135A-0.

Also, the newly-installed communications hardware is officially the RSPI-M (radiotekhnicheskoi sistemy peredachi informatsii, "radiotechnical information transmission system," I think - but don't trust my Cyrillic romanization).

And do we know what cargo ship brought it up? Progress MS-23?

I found one wire-service article that says it came up on Progress MS-21, but I can't find any other confirmation of that claim.

Excellent quality coverage right there Yellowstone10, love your commentary (and the fact that you're attending to the important stuff during Zoom time ;) )! Thanks again for a coverage that really stands out, and allows interested yet away-from-the-screen-in-the-worst-moments people like me to follow along after the fact, getting up to speed while sparing a chuckle or two. Most appreciated.

- Impakt was installed on VKD-43, 17 August 2017

The first Impakt was installed during VKD-43, but the second one (which was retrieved during VKD-59) was installed during VKD-47, on 18th November 2020.

Good catch, thank you! (Unfortunately NASA's ISS status reports transliterate it to Impact, which shows up all over the place in search results, very seldomly referring to the experiment in question.)

I'll update my post accordingly.
