Title: VKD-45a Russian Spacewalk (Dec 11th, 2018)
Post by: eeergo on 12/07/2018 06:45 am
Starting the thread to cover the upcoming Russian EVA/VKD-45a (not 46!  ;) ) whose main objective will be the exterior inspection of Soyuz MS-09 in order to ascertain more clearly how the infamous hole on the Orbital Module, on the pressure hull close to the toilet's deposit, came to be.


Leading theory appears to be a production issue that was somehow covered up, and the repair material got sucked out of the hole towards the exterior of the spacecraft after some thermal and pressure cycles prodded it loose. Of course, this appears to be just speculation at this point, and finding the hypothesized loose repair material trapped between the hull and the thermal blankets. Also, an external view of the damaged area should give more information on how the hole came to be, as well as how the new epoxy repair is holding up.


I don't have any information about secondary objectives or get-aheads at this time.

I thought I haven't seen this on Russian forums and media, but it appears I was wrong.

The latest info from TASS ( https://tass.ru/kosmos/5875183 ), dated 2 days ago, shows this EVA is still scheduled for 11 december.

Kononenko also joined Flight Engineer Sergey Prokopyev to ready a pair of Russian Orlan spacesuits for a spacewalk on Dec. 11. The duo will inspect the Soyuz MS-09 crew ship that will return Prokopyev, Gerst and Serena back to Earth Dec. 19 U.S. time.

MEDIA ADVISORY M18-184

Coverage Set for Russian Spacewalk at International Space Station

Two Russian cosmonauts will venture outside the International Space Station at 11 a.m. EST Tuesday, Dec. 11, to conduct a six-hour spacewalk. Live coverage will begin at 10 a.m. on NASA Television and the agency’s website.

Expedition 57 Flight Engineers Oleg Kononenko and Sergey Prokopyev of Roscosmos will use this spacewalk to examine a section of the external hull of the Soyuz MS-09 spacecraft currently docked to the space station. In late August, a pressure leak occurred on the space station that was traced to the Soyuz. Within hours after finding the source of the leak, the Expedition 56 crew sealed the hole and the station has since maintained a steady pressure.

The cosmonauts will take samples of any residue found on the hull and take digital images of the area before placing a new thermal blanket over it. The samples and images will provide additional information that will aid the investigation into the cause of the pressure leak. The cosmonauts also will retrieve science experiments from Rassvet before heading back inside.

Kononenko, extravehicular crew member 1 (EV1), will wear a spacesuit bearing red stripes on this spacewalk, the fourth of his career. Prokopyev, on his second spacewalk, will bear blue stripes as EV2.

Prokopyev, NASA astronaut Serena Auñón-Chancellor, and ESA (European Space Agency) astronaut Alexander Gerst are scheduled to depart the station in the Soyuz MS-09 at 8:42 p.m. Dec. 19, returning home to Earth after a six-and-half-month mission.

Overview video by Energia showing the training (not in the neutral buoyancy pool, is it still not operational?) for tomorrow's EVA.


It will involve major MMOD cutting, so expect lots of small debris flying out in this EVA. Note the "space dagger", "space scissors" and "oversized space shear cutter"  ;D :o

No, it is not.

Are there any schedules for its rehabilitation? By the way, is the drained pool the place where this training took place or some other facility?

It's kind of funny how Navias keeps repeating the swabbing is intended to analyze how the internal epoxy repair went, to have new data for future possible repairs... when it's been stated many times, and is actually more credible, they're looking for exterior traces of whatever held the drill hole closed until the leak sprang.

Had a hard time getting his foot locked in. What happens if he cannot get it to unlock again?

The problem seemed to be 1) difficulty getting the foot restraint in position and 2) apparent lack of coordination to position Oleg in a way that he would line up with the foot restraint and at the same time not drift away from it. Once he did that, it was not time-consuming to get into it, so shouldn't be difficult to release it either.

Some more hacking action with the dagger. Remember Orlans are easier to get to space with because of their higher pressure, but that's the very reason why they're less plastic, and consequently much harder on the hands and muscles. Oleg's hands must really be hurting by now.

No knife; 3rd try(?) he was successful in snipping off and retaining the end of the extrusion with forceps!

MCC-M asking them to carefully stow the sample.

I didn't catch the full dialog--are they using sandpaper on the extrusion?  Buffing it flush, and/or as a sample gathering technique?

Answer: (sandpaper?) swab, held in handling device, is used on the extrusion for sample collection.  Sample stowed in collection container.

"Meta-question" for later:
Did anyone outside of the Russian ISS/Roskosmos circle of experts visualize this EVA proceeding like as it has thus far?

(Brute force cutting vs. fine tools, tethering to thermal insulation cuts, etc.)

"Meta-meta-question"
And is this a manifestation of ISS = Freedom + Mir 2; two separate programs that happen to be joined together, but are executed independently where/whenever possible?

How do you tidy up the entire orbital plane now with all this debris?  Yes, I know some of the debris will decay orbit in a number of months/years... but still.  I'm sorry, but this whole thing just did not sit well with me.  What was the gain for exposing spacewalkers to knife blades and sharp edges, and creating a year-long cloud of debris in that orbital plane?  The NASA Safety Department must be in defibrillation.

(Strike-through by zubenelgenubi)

Seeking correction from our forum experts:

The debris has low density and high surface area/mass ratio.  Such debris will decay well below ISS altitude in hours or days, and decay out of orbit in weeks or months.

That may be a rationalization, but it may serve as justification, too.

As to the sharp, pointy tools and sharp edges: that's a Russian decision on how to use their cosmonauts.

That also may be a rationalization, but it may serve as justification.

I'm sure JSC and NASA HQ had adequate staffing trained in auto-defibrillator use on-site during the EVA. :)

Collecting a sample of the epoxy used on the original repair helps them determine when this non-standard repair was made. If everyone is clammed up out of fear of retribution this information might get someone to speak up so it can actuall Be addressed.

Great thread, thanks.

I'm watching the live video feed (backtracked a few hours) - did I see correctly that:

1) the end of the plug seemed elastic.

2) while they initially had the sample in the clamp, Oleg didn't latch the clamp, and I swear I saw the sample float up and away from the clamp and into the insulation.  Did they retrieve it, or was it lost?

3) do we think the visible portion of the plug is from the original plug, or the one they injected in space?  it looks a lot like the sealant they used inside, and it seemed elastic.  there's so much chaff all over the place, i wonder if the original plug got lost?

4) I swear I also saw a lot of scoring on the outer surface of whatever it is the plug was protruding from.  Are we thinking that was from the space knife, or did I see incorrectly?

This is amazing.  I'm glad I got to see the full live feed... sausage making indeed.

Hindsight is a wonderful thing, I wish I was born with it. Upon reflection I very much feel that the risks involved with this particular EVA did not justify the ends. I am not sure what particular insight the Russians are going to get from this, apart from someone drilling a hole they shouldn't have. The risks to the two brave cosmonauts and the potential for troublesome debris on the ISS and further damage to the Soyuz just seem too high for the result.

Why am I wrong?

maybe we don't know the whole story, and that hole has not been made by error.

You're not. Literally everyone in my office watching the EVA had the same sentiment. I've never seen anything like this.

Is that going to be a problem?

Considering the suspicions that have been voiced that the hole was drilled while in a microgravity environment, one would think collecting additional evidence that could point to what really happened would be considered worthy of some effort. Perhaps not everyone is yet ready to write the entire incident off as the result of shabby Russian quality control.

That's an awful lot of risk to the vehicle and crew to find a scapegoat and avoid doing proper RCCA.

It was definitely hair raising.

That said, pushing the envelope in the context of a well defined mission is arguably worthwhile as access to space becomes less and less expensive.  For example, I think all the little issues they ran into yesterday are a perfect list of action items if they want to (or must) conduct a repair in the future, or if they want to plan a repair to be performed by a robot.

Some random thoughts:
- Leverage is way more important than they contemplated.  I'm fairly certain that time spent wrapping a rope around the fuselage to secure the legs/working posture of the cutting astronaut (but allowing multiple orientations/secure points) would have saved them time in the long run, and I think it would have been safer (I saw the knife and the shears have at least one important strap along their business ends, as Oleg struggled to get himself into position and cut).  Plus, the strap could have been used to help secure a cover over the hole in very little time.

- Forceps don't work with spacegloves, and two handed operation sucks.  You can't always have the perfect tool (though, they had the pic of the litter given that Dragon had just shown up), but you could generalize a lot of tools to work better with spacegloves AND be usable for internal maintenance.

- Two handed tools either suck or require better non-hand leverage strategies.

- Hand-bendable sheets of material would be helpful, if they could work like moldable clamps in space. 

- There's got to be a better way to keep tools organized in an EVA repair scenario.  I'm thinking it would involve magnets.  The straps would still be there, but the magnets would help keep things from becoming tangled.  Or something.  If the leverage strap had been in place, maybe there'd have been a better place to secure the tool box and they wouldn't have had to deal with the rats nest at the end.

- Maybe there's a way to carry some kind of broad spray that could be used to gently blow away debris.  That might be impossible given that everything condenses, and there's always going to be some special surface nearby (sensor, PV cell, radiator).  Maybe a static charge badminton racket-like thing that could be used to snag things?

- Did I mention leverage? 

Some other benefits to getting at this plug:

- They've not had a chance to see what the material does in a live plug - now they might have information that could help them come up with a better plug material that, perhaps, would not degrade as quickly over time.

- They might have information that could help them come up with a better plug strategy (or, they've confirmed they have a good strategy).

- They might have better information on longevity of a plug repair, in case they have to reside in the habitation capsule for an extended period due to space junk holing the ISS.

Plus, in addition to all the above... there's public and political pressure to attempt to get at the plug.  I would say it was also excellent press for the ISS (at a time it needs it), but I don't know how many people saw it, or know they can view it.  Frankly, I can't think of anyone who wouldn't be glued to the video after the space knife made an appearance.

I promise I won't post a lot of long things.  ;)

Many of the "issues" the EVA crew ran into yesterday were certainly addressed (successfully!) during all of the Hubble repair EVAs over the years!  Of course, a lot more training and specialized tools/hardware went into those activities.  But, it does seem like tighter US/Russian collaboration on yesterday's tasks could well have helped enormously!

The cooperation between NASA and the Russians on this spacewalk probably when something like this:

Russia: We want to do a spacewalk to rip open the soyuz and examine the hole.

NASA: What?? Are you out of your frickin mind?!?!

Russia: Never mind, we'll do it our way...

Edit to add: in all seriousness, the Russians knew the risks of this spacewalk just as well as all of us on this forum, I have no idea what they were after but it was clearly important enough to them to justify the risk.
The question is whether we will ever get to know the full story and reason for this.

Please note:
The Russian neutral buoyancy facility has been out of order for some time--this was mentioned up-thread.
(not in the neutral buoyancy pool, is it still not operational?)

No, it is not.

(I believe it's been mentioned in other threads here.)

AFAIK, they have not asked to pay to use similar 3rd party facilities outside of Russia for training.

Good Question. I'd like to know too. Is it going to be a problem?

I would think that debris cloud moving at nearly the same speed as a craft moving through it would not present any serious danger.

It would be more of a danger to satellites in orbits different to the ISS.

Wouldn't these very lightweight bits of insulation and foil reenter in just a matter of months, or maybe weeks?

From up-thread:
Seeking correction from our forum experts:

The debris has low density and high surface area/mass ratio.  Such debris will decay well below ISS altitude in hours or days, and decay out of orbit in weeks or months.

That may be a rationalization, but it may serve as justification, too.

My new question: Is any of the debris being "discovered" and having a satellite ID # assigned and TLEs generated?

I doubt, flakes of insulation material would show up on radar. They are also going to descent to lower orbits quickly, so no danger to ISS itself. But visiting vehicles by definition come from below, so their phasing orbits are goung to be in the orbits where the gunk is goung to end up. Luckily, its going to be low relative speeds of dozends, maximum hundreds of meters per second, and the debris is very fluffy. Should not cause critical damage to anything, but ... might get some people at NASA with micrometeorite-damage-paranoia worried.

The ISS schedule has no Visiting Vehicles launching until January 18 at the earliest (SpX-DM1).  Past that, the next VVs arrive in February and/or March.  I >assume< the debris will have decayed from orbit by then.

It may be a moot point--THIS time--because there won't be any ISS-bound vehicles to potentially endanger.

Maybe that was taken into account when this was scheduled.

Yes, I concur.  This EVA occurred near or in the high-beta cut-outs that occur near the solstices that restrict dockings and berthings to ISS, yes?

As a larger issue, I'm interested in how planning for this EVA occurred.  And, what the reaction on the USOS side was as plans progressed.  If anyone from NSF can learn anything...

Given the circumstances, I'm not holding my breath. ::)

I'd also be interested, weeks or months down the road, to learn if anything useful is discovered during the sample analysis.

Any debris will either decay quickly or be co-orbital, posing at most a 'firefly' risk when illuminated by laser rangefinding - but that's not terribly likely.
