BBC were reporting 1 of 2 leaks are apparently fixed so it was at least a partial success.

There aren’t even doors between sections. Airlocks are serious things, there is one or two for station for EVA. There are multiple hatches for docking spacecraft.

One of the innovations of ISS is larger docking adapter with bulkhead that is removed after docking. Russian section still uses hatches. All of the cables go through the docking adapter or hatch which makes impossible to close door or quickly disconnect.

... for now. Problem still being worked.

I read it as an inability to measure the leak rate immediately after the repair. If the rate is slow, measuring it takes time.

The Zvezda module has been in orbit since July 2000.

I don't think any crewed interplanetary mission is going to last that long for the foreseeable future.

I think the service module is both structurally and functionally critical. If it is failing and you do not know why, catastrophic failure is presumably possible, not just some air loss. A hole or crack in the module is now apparently double the size it was until recently, that is a trend that presumably could continue to rapid unscheduled disassembly.

Compression loss can lead to a decompression of sorts if I had to guess... it is a vaccum out there. The force from a decompression can yield a chain reaction or strongly disrupt the entire station.

The rule is that at all times enough return vessels must be docked to the ISS for everyone on board.

These are usually the same vessels they used to get up to the station.

This has the consequence that if they need to re-dock one of the vessels (for whatever reason) all the astronauts that would normally use that vessel must board it for that menuvre. Just in case it fails to dock again.

And they don't normally have spares.

IIRC, this is a good video on the topic: https://m.youtube.com/watch?v=82YHM12n2JI

> Naively, I would assume that there are airlocks between the different sections of the ISS.

There are not. The airlocks on the ISS are either docking modules for spacecraft, for spacewalks, or for deploying satellites.

The crew shelters in the vehicles so that in case of an emergency they can evacuate immediately.

They're not flying to Mars in a 30 year old Russian rust bucket so

A bit of a tangent, but the fictional book "Children of Time" takes this to wild extremes. Really fun read

A little off-topic - the movie Stowaway (on Netflix) is a good movie about journey to Mars.

Then you die and go into the history books.

Recently started an embedded hardware/software job. Shipping firmware to the manufacturer feels like that for the device classes that have no internet.

Ideally your Mars transit vehicle hasn't been taking 90 minute heating and cooling cycles nonstop for 26 years.

If things go wrong, they're already in the vehicle supposed to bring them back. It might be upsetting to be 3 locked doors away from your best way to come back home

There are normally-open air-tight hatches between modules. Various utility connections and air ducts are normally run through the open hatches so it would take a bit of work to disconnect these connections before they could be closed.

Not exactly something you want to be doing under time pressure.

Well, I won't claim to know the answer, but "please do not move between different airlocked sections while this work is underway" sounds a lot like the definition of "shelter" to me

Sort of like what happened on the Apollo 13 mission in 1970. Engineers on the ground were able to devise a makeshift fix to adapt the control module airscrubber filters to fit the lunar module so the astronauts could shelter in the LM for several days before getting back into the CM and coming home.

There is less debris around on the way to mars and this is a known and worsening for the ISS due to its age.

Seems like these structural integrity problems are always inside the Russian section. So if you're on a Russian mission to Mars, yes it would be reasonable to be worried. Otherwise this seems like a non-issue.

For every complex, difficult and hard problem, there is a simple, easy and wrong solution.

Paint obviously is not the right tool for making seals air tight.

I can’t quite imagine, even shipping on prem stuff is much harder than the cloud. Especially when people can mess with stuff

Anything special you noticed about the deployment processes involved with that versus more typical software engineering work?

Well one side will be facing the sun and the other will be facing the void, so there might be similar issues.

My first week on the job they told me they're about to manufacture 20k units and can you please fix this bug in the firmware by Friday?

I've never shipped anything to real customers in the wild before, so let me tell you how insanely stressed I was to open the firmware and find a 10k lines of C contained entirely within a single switch statement. I think they used some no-code tool to graphically design a state machine then plopped the generated code straight into the device.

Interesting thought. Isn't it possible to design around this?

Surely this was considered when building the first modules.

This is the right answer - if it goes wrong they are already placed in the escape vehicle, sitting in their space suits.

> vehicle supposed to bring them back.

Love the use of the word supposed there.

Dragon is built by Space X that has a track record of blowing things up.

What’s the reason against separate conduit for utilities?

A top (arguably, the top) metallurgist who studied previous failed parts told me it's corrosion of the Russian alloy used.

Corrosion is a hard problem in living quarters (ie moisture and salt) in space (sealed with no gravity)

In this case, per the article, "shelter" meant "shelter in a capsule capable of returning to earth and put on the spacesuits that you wear during return to earth".

I.e. leaving the actual ISS structure entirely.

Yeah I was thinking about that, the big difference being that you are months out instead of hours/days, if a return to Earth is even possible.

>Otherwise this seems like a non-issue.

Except you forgot to mention an epic leak in Destiny just three years after it was attached to the ISS: "At its highest rate, the station was leaking about 5 pounds of air per day overboard." [0] Imagine that happening on the 4th year of American Mars mission.

Also, if you on American mission to Mars, it would be reasonable to worry about cooling system dying mid-flight requiring three spacewalks to fix it: "We'd lose cooling capability to half of the electronics on the U.S., European and Japanese part of the space station." [1]

You ever try to open an old paint can? Checkmate, atheist.

Unless your spacecraft is built by Boeing.

We had two astronauts stranded in space for the better part of a year just last year!

Seeing nothing wrong with it. If journalist follows inverted pyramid, it starts with crucial facts and at the end it can be mostly supplementary information. Seeing this is about "International Space Station", this adds context to why it is called "international" for an ordinary person.

It's complicated. The US Orbital Segment of the ISS consists of modules funded by and built in the US, ESA/Europe, and Japan.

https://en.wikipedia.org/wiki/US_Orbital_Segment

Several of the US modules were built in Europe by Thales Alenia Space and were transferred to the US in exchange for the US launching the European modules on the Space Shuttle.

Cardboard's out. No cardboard derivatives.

Paper?

No Paper. No string. No sellotape.

Yes and I believe they do regularly use them on the Russian side, at least.

They were also the cause of a fire on Mir. https://en.wikipedia.org/wiki/Mir_EO-23

Some fire decal while they're at it?

Who is the "they" in your post? The ISS is a bit interesting because its a cooperation between NASA and Roscosmos.

Yeah, this is their "live reporting" feed, where updates and context get posted about an in-progress event.

I don't think you'll find that type of language in the more traditionally published/edited articles.

They were definitely used on Mir- in 1997 one caught fire, blocking the crew's access to their escape Soyuz, though they put it out.

It looks like NASA helped redesign it to be safer, creating the modern Solid Fuel Oxygen Generator (SFOG) system still in use on the ISS as the backup.

OceansGate happened because they cut corners.

I feel like NASA won’t be sling this anymore…

A big motivation behind the creation of the ISS was an attempt to use scientific collaboration to promote peace between the two big opposing super-powers during the war, the URSS (basically Russia's communist empire) and the USA and to focus both nations resources into peaceful space research that could benefit the whole mankind.

Several other countries contributed, in an attempt to include other nations, but for all practical purposes it is an American/Soviet(Russian) project from a more civiled age of international competition. I think its appropriate the article remind us of this. A lot of people wasn't born them, and have no idea that once science had less borders.

We've updated it above. Thanks!

(Submitted title was "Astronauts on ISS told to shelter as repairs under way to fix air leaks", no doubt because that's what the article said at the time.)

Agree to precautionary principle. Disagree to certainty of fixing because this is a long standing leak which just doubled in intensity: either it got bigger, or there are more. Either way, we have no reason to be optimistic a bigger leak problem has a faster MTTR or even triage.

> But I wonder why it is impossible to do.

Because, space. It's hard. Unbelievably hard.

Elon wants a lot of things that aren't happening.

For every human onboard ISS there is always place in the docked spaceship. Exceptions: when spaceships break, replacements are usually sent - like, when Soyuz lost coolant or Starliner was considered too unreliable. While waiting for replacements, those ploblematic spacecrafts still serve as lifeboats, except maybe Crew Dragons can carry more people than those 4 they usually carry...

Software can be updated and patched, even if you have to manually email customers a bespoke exe that pokes bytes into a compiled dll.

Generally firmware can't be updated by the end user because there is physically no way to do so without returning the hardware. (Unless an update mechanism is specifically implemented in hardware, obv)

Pucker factor goes way up because if you ship a bug, there's no way back. If you aren't careful, you can break physical devices which can have consequences anywhere from thousands of RMAs to burning down a user's house depending on the hardware and how bad you fucked up.

The deployment process itself is about the same. Tests and more tests, including testing on prototype and/or pre-production units. Hardware testing can get wild depending on application, but I don't think any SWE would find it too surprising. Then you email a binary to your manufacturer and pray

Of course you can, but "needs to survive 26+ years" was very likely not part of the original design goals. The designers of the time probably wouldn't have expected the dysfunction to be so deep that 26 years later, only the Chinese can seem to stick to a plan.

That's not necessarily true. Even spaceships in LEO will perform temperature-driven rolls so as to distribute heat and radiation. I have to assume that long-term ships like interplanetary transport will do the same.

Nearly the same experience. Had to fix an issue in a boot loader. It came down to improper setup of the memory controllers ECC engine. It would correct and ignore a single fault. If you managed to get two faults it would raise an exception that was not handled and the boot would fail. For the customer this meant that a reboot might randomly brick the unit until you go in and manually power cycle it.

Just convincing them that their problem boiled down to a single incorrect bit was difficult enough but then having to, in a day, build and successfully operate a test harness to prove the fix worked was the real stress.

I do not miss embedded engineering.

IIRC during transit you'd want as much mass between you and the Sun (as shielding), and as small of a cross section facing the Sun. Probably also to reduce heat reaching the propellants.

So in a cylindrical ship you'd want to have one end pointing at the Sun most of the trip. This is, of course, very different in effect on the hull compared to the repeated expansion and contraction of heating cycles.

There'a maneuver called a "BBQ roll" where you basically set the craft to doing a barrel roll in order to prevent any one side from overheating. I image that could help some.

It is not obvious to me that there is no specialized type of paint that would be appropriate.

Doing the whole module sounds like a lot of mass though.

Debris from what? Satellite debris get in that orbit?

Ah yes, the well traveled and highly tested human mission to Mars.

Flexseal obviously

This is just not true. There have been leaks due to micrometers in just about every section of the ship at one point or another. A quick search pulls up examples of US modules having issues, especially around interfaces and seals. NASA had a whole investigation between 2018 and 2021 about the recurring issue.

Probably better to link to the article, rather than a thread that has 0 comments.

https://www.reuters.com/world/nasa-live-international-space-...

Candles are useful when oxygen has been consumed because of respiration or a fire. They're not useful in a leak.

Conservation of mass: if a cubic meter of air escapes, that's 1.25 kg, and you need at least that much in candles. (You actually need 2 kg because the candle isn't solid oxygen)

There's ultimately 1.2 t of atmosphere on the ISS. This will also result in a pure oxygen atmosphere, which is dangerous. You need nitrogen.

Some problems i can see with that:

It might be hard to access the actual pressure hull from the inside (there's probably insulation and padding on top)

If you use paint, you somehow have to get rid of the solvent in it when it dries, which might be a problem when painting a whole module

Zvezda has been leaking since 2019. That doesn't seem sudden and without warning to me. I imagine its going to continue to leak until the ISS is decommissioned.

Hmm? If you mean the capitalization, that’s BBC style.

If you mean on the outside, paints that apply well in vacuum and microgravity probably need to be developed and tested first.

If you mean on the inside, it'd be a lot of time and disruption to devote to maintenance on a station that's already having to spend an increasing amount of time on maintenance instead of science.

The modules have a lot of stuff that has been wired between them over the years, all that would need to be sorted out, consequences understood and more before ever starting the work, and by then it'll be time for the ISS to retire anyway.

I think it's an attempt to express that the station consists of only two segments: Russian (ROS) and US (USOS), but the US invited its allies to work together on its segment. So parts of the USOS are made in Europe, Canada and Japan, and generally lifted to space by the US, usually on the Space Shuttle.

(All this was pretty lucid of the US, but obviously the Russians did no such thing on their side. The Japanese even managed to get an ISS resupply mission launched on their own vehicle, which is no small achievement, and the ESA did a bunch of good science. And what would space be without the Canadarm :-)

Do you mean the Bbc?

yeah, why can't they just make astronauts wear goggles, then stop the fans, and tell them to squirt some superglue in the air to let it clog the hole?

There are of course potential failures, but not quite as violent as oceans gate. There is 1 atm of pressure difference between the inside and outside of the ISS. At titanic depths the pressure difference between inside and outside of the submarine was approximately 400 atm.

Thats why the ISS can have small leaks like this that are a problem but not catastrophic like they would be in a deep sea submarine.

Oh, so it's a live blog with updates and a dynamic headline.

You can design around a lot of stuff but what you encounter in orbit will ultimately laugh at that bandage and eat it away. AtOx, hard UV, and radiation levels you don't get on Earth just have their way with everything in orbit over time.

You don't get the AtOx going to mars but you have everything else which will utterly take its toll on a traveling craft.

Look on the bright side, at least you're not riding in Boeing's capsule.

... and returning is mostly by gravity.

Not for crew carrying craft.

In microgravity, everything gets everywhere. My mother worked on NASA funded research for diagnostic spit tests to determine chronic versus acute stress, which previously required blood draws, which are a less than optimal choice in space. It's all very stressful.

It seems as though the leaks are always in the Russian section? Perhaps this is why. Humans are the weak link. Damn breathers.

I would guess they're worried about breaking something, but thanks for the clarification (and apologies for not having RTFA)

I'm not sure distance matters. They're still stranded with virtually no possibility of rescue from the ground. Apollo 13 was extremely lucky that the hull wasn't breached, the spacecraft could still be controlled, that some very smart guys on the ground were able to devise the fix using bits of stuff known to be on board, the filter could actually be made, and, most of all, that it worked.

Why did you feel the need to post this comment?

How about glue?

Is there any rocket-builder without a history of blowing things up?

I was wondering about this as well. In theory, there are also some metals and compounds that react with each other with just simple contact which result in some kind of amalgamation which can result in disastrous structural loss. Veratassium recently did a video on this kind of effect[1]. Could this be happening here?

[1]: https://youtu.be/ksn5yrsC3Wg

Bits of spacecraft falling off (Challenger's windshield was famously cracked by a paint chip), debris from satellite collisions, even anti-satellite weapons tests.

Most of the things that will be a common danger (that is too small to track) are tiny pieces of stuff. Think paint chips and sand grain sized objects. These can be from things that came off rockets and ships, and things we've left behind like experiments and satellites. When these tiny things intercept you at many kilometers per second it can be dramatic.

Anything larger, say a lost screw driver, would punch thru the ISS like it wasn't even there leading to some ugly consequences.

I did an internship at NASA. What they told me is that anything larger than a golf ball they track while anything smaller than, I think they said a penny, is too small to do damage. The problem is debris that's in between the two. In that case they only get a relatively short warning (it's been a while but I think it was on the order of a couple hours).

The ISS can dodge debris by adjusting the height of its orbit.

Debris from space. Lots of rocks are constantly falling from space from all over. Sometimes they're big and make pretty lights in the sky as they fall, often they are practically invisible.

Maybe we can use the goop from those self sealing bike tires to have self sealing space station modules

Why would I steal a link from someone who submitted a story first and take credit? I know it's normal behavior in tech to stab everyone in the back but...

"The air leaks escalated on Friday from a pound of air per day to two pounds, according to a senior NASA official who asked not to be named.

Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikayev were using a saw to break into an area where they believed they could access the crack leaking air, the NASA official said.

NASA officials disagreed with this method, the NASA official added, prompting mission control in Houston to order safe-haven procedures."

It's hard vacuum on one side. There's a reason the word "hard" is used to describe it.

A few years ago a Soyuz was improperly drilled during manufacture. This was patched with a super epoxy... and then began leaking air on orbit. Paint won't seal what a super aerospace epoxy failed to seal.

This is just wrong. All serious issues that turned out to be safety concerns were in Russian modules. The 2018 leak you refer to here was in a Soyuz capsule and the 2021 leaks were in the Zvezda module (same place they are this time). In between there were also minor leaks in the Zvezda connection tunnel.

You're being sarcastic, but I would like a technical explanation of why this would not work.

The 10 non-Russian modules have been in vacuum for a quarter century and have done just fine despite facing more debris than in interplanetary space. So yes, this aspect is well tested. This stuff is literally part of the reason why the ISS exists in the first place.

The return of the leak was relatively sudden. They had done temporary fixes that brought stable pressure for a while, and when it reappeared, the leak jumped back to 1kg/day quickly.

No, because you don't pronouce that as “the bibs”, you say the letters.

Put a bit of spare sheet metal over the hole and let the pressure differential hold it down. For added safety affix a post-it not with DO NOT REMOVE written on it in all capital letters and underlined. They can even use those special zero-g ballpoint pens they spent eleventy-billion dollars inventing back during the johnson administration.

They did use space tape (Kapton) and epoxy for that weird case with the hole drilled in the ISS.

If such a conduit would connect two sections that the hatch is meant to isolate, you would have to make the conduit and everything running through it airtight, even under a catastrophic loss of air. If the conduit didn't seal as well as the hatch, which is meant to withstand hard vacuum on the other side of it, it would defeat the purpose of the hatch.

can't one of them just put his thumb in the hole? duhhh

I thought it had a pure oxygen atmosphere to prevent the bends? Why is it dangerous?

That sounds weird. They write "Nasa" mid-sentence too, yet keep other acronyms (ISS) intact.

Air filtration is one of the hardest things do deal with in space.

I don't know what solvents would do, but I remember that astronauts' bone density loss in space means there are challenges around managing the significant amount of calcium captured by the air scrubbers in the ISS.

> well in vacuum and microgravity probably

Wouldn't all paint works well in microgravity? If it didn't, I would think you wouldn't be able to apply it to your floor, walls, and ceiling, with the same paint.

>but obviously the Russians did no such thing on their side

Why obviously?

The USSR invited cosmonauts from all over the world to fly and work at the Salut-6, Salit-7 and Mir stations.[0]

That's France, Britain, Austria, Japan, India, Soviet block countries, Mongolia, Vietnam, Syria and Afghanistan.

Oh come on you can't be serious.

Clearly this needs some JB-Weld :P

>Why did you feel the need to post this comment?

Maybe parent feels like rocket science is a field that should have few launch failures?

I can't give you a quantitative answer since I'm usually focused on new research rather than what company/nation did said research... but their stuff does seem to blow up on the launchpad more often than NASA's :-)

Bubble gum? Like do they chew space bubble gum that they could then smoosh in the holes?

In college, we'd use toothpaste for the holes left from nails in the walls we hung up our posters with.

Duct Tape, the answer is always duct tape

No. Blowing things up is the reason for rocketry to exist and its historical basis.

A fun fact about SpaceX:

Remember our esteemed national American hero, and spiritual father of SpaceX, Wernher von Braun.

Wernher wrote a book about Mars referring to "The Elon", an imaginary Mars governor, and the father of Elon Musk claimed that Elon's name came from there.

Well at least, that's what he claims. Reality doesn't matter if you have billions and power. History can be rewritten.

I really detest Musk but Dragon has had a really good track record.

You'd still need to pull out the utilities and close a now second hatch in the conduit to seal the thing. What would be the point?

Just a guess: Harder to build and operate with more failure modes and less opportunity for intervention.

Those would need to be connected during docking and sealed separately anyway if you wanted to seal the hatch. More failure points.

Are you referring to galvanic corrosion? That's well understood and I'd hope not an issue in spacecraft manufacturing.

> There's a reason the word "hard" is used to describe it.

Because it's more extreme.

Do you think a soft vacuum of 0.002 atmospheres of pressure would be notably easier to prevent leaks into?

> A few years ago a Soyuz was improperly drilled during manufacture. This was patched with a super epoxy... and then began leaking air on orbit. Paint won't seal what a super aerospace epoxy failed to seal.

Wasn't the fix on the ground a secret patch by the person that drilled the hole? I don't trust that to have been done properly.

And then when they noticed it was leaking... they used the super aerospace epoxy. Which was labeled as temporary but as far as I know it's still the fix.

Also that was a serious hole, 2mm wide, not a microhole like you'd try to fix with paint.

They just didn't have enough of reserved general purpose connections for future use. I guess this woild be especially the case with the Russian modules, which were literally surplus Soviet manned space army outposts(such a thing do not make a lot of sense, they did it anyway).

It has "Live Updates" in big bold text as one of the first and most prominent lines on the page so... yes? Is that a problem?

Publications have had live-updating articles for things ongoing for years. This seems both entirely reasonable and normal, and I'm not sure what the concern or issue is.

The differences in engineers for space versus the ocean are fascinating. You'd think space stations and submarines would be interchangeable because they both deal with pressure differentials, right? Wrong. They'd fail in fascinatingly different ways within minutes or hours in the opposite environment

If you count the Soyuz leak, then the Boeing counts too! That was far more serious than anything you listed.

Two astronauts stranded for nine months taking the ISIS supplies intended for others. This is after they safely docked, which was considered risky at the time.

Delta P

The hubris of forgetfulness; to think that until Elon showed up the West couldn't even put a person in space anymore.

The Soyuz, the MIR, the human space records, the Venera program, closed cycle rockets, all have no equivalent in the West. Even their version of the shuttle was superior (it flew 100% autonomously).

I don't like Musk, but he single handedly saved the Western space programs.

Wouldn't the calcium go out in your urine?

Do they literally sweat their bones away? I can imagine how it would work on molecular level via sweat / breathing, but I would expect >99% to be simply pissed and shat away.

Not OP but I’d imagine the big problem with microgravity is not after application but during application. No idea the scale of that problem but obviously open cans of liquid paint are not realistic (not that anyone was suggesting they were)

USSR, yes. But the ISS was launching during a time when USSR no longer existed and Russia was fairly isolated. Hence, "obviously": US at that time had many close allies, but Russia had only a few, and not as technologically advanced.

Apollo I disaster suggests pure oxygen atmospheres are to be avoided.

Some style guides distinguish between an acronym (Nasa, say the word as it's written) and initialism (ISS, say each letter)

I think it's hard to say. Water sprayed at a ceiling doesn't congeal into a ball the way water floating in microgravity does.

Paint that would fall to the ground if it didn't stick to anything on Earth, would just be floating around in microgravity. Any dissolved gasses or moisture can usually passively sort themselves out due to their differing masses, but again, not in microgravity.

Flex Seal would be my suggestion. It works as seen on TV

NASA does not produce any launch vehicles. It produces payloads and buys launch services from others.

Unless you count test artifacts, an actual catastrophic failure of a rocket on a launchpad (or even in flight) has been rare in the last 10 years.

It's time to kick ass and chew bubble gum... and I'm all outta gum

Don’t try this if your toothpaste is the blue or green minty flavoured type. You’re welcome.

Isn't the main problem finding the hole and not what should be used to fill the hole?

As per submission guidelines:

So, even if you use original title, once "Live Update" article changes, it might seem that submission did not use original title.

Professor Hubert Farnsworth: Dear Lord! That's over 150 atmospheres of pressure!

Fry: How many atmospheres can the ship withstand?

Professor Hubert Farnsworth: Well, it's a space ship, so I'd say anywhere between zero and one.

You brought it up. I have been talking about structural issues with long term core modules. And that is clearly a Russian issue.

The Boeing mission was scrubbed out of an abundance of caution. IIRC, nothing bad actually happened.

How about _Space_ Flexseal?

Delta P is one atmosphere or less, like 15 PSI. Lots of stuff can handle 15 PSI.

Now, will it immediately off-gas and embrittle on exposure to vacuum? Different question.

I didn't realize Buran flew, and flew autonomously. Impressive for the times.

And the 1961 fire that killed cosmonaut Valentin Bondarenko in an altitude chamber. The Soviets covered it up until the 1980's, so NASA made the same mistake.

Yeah, the application system is probably the tricky bit, rather than the paint.

> Any dissolved gasses or moisture can usually passively sort themselves out due to their differing masses, but again, not in microgravity.

This is a solved problem with the ECLSS system [1], required from humans releasing ~3.3 lbs of water per day, and exhaling gases that must not accumulate or form dead zones, and normal VOCs scrubbers [2] due to most modern materials releasing them.

I suspect it would be more of a "how many extra filters do we send" type problem and cycling the collected water a couple more times.

"To show the powerful adhesion of flex-seal, I sawed this space station in half!"

This sense of national pride based on long past achievements will always be bewildering to me. Do you really think a country that is actively engaged in a full scale open land war and whose economy is in shambles is able to maintain (much less build) a venerable space program? Elon might have saved the American tax payer from the senate launch system jobs program, but the majority of the global space industry is and always has been in the west. Russia has been an afterthought since the collapse of the Soviet Union. And it shows in everything they have done in space since.

Yes, including the BBC’s: https://www.bbc.co.uk/newsstyleguide/all#:~:text=our%20style...

We actually did this in my freshman dorm room, as the paint color almost exactly matched the original Crest "green".

"Do you really think a country that is actively engaged in a full scale open land war and whose economy is in shambles is able to maintain (much less build) a venerable space program?"

Don't blame Russian space failures on the war.

Roskosmos was robbed blind by the likes of Dmitry Rogozin long before 2022. The Angara heavy launcher project has been started in the 1990s and still reminds me of Duke Nukem Forever. The Vostochnyi cosmodrome has been a black hole in red numbers for some 15 years etc. Things were "meh" even during the times when oil was 140 USD per barrel and Russia had no sanctions going against it.

They're not teenage boys.

Well, they managed to rebuild their launchpad ahead of schedule and launched this big boy not long ago:

https://www.space.com/space-exploration/launches-spacecraft/...

They've also got some new passenger jets certified and about to enter production (MC-21 and SU-100).

That certainly explains it; this particular acronym is even called out distinctly in the style guide.

But "Nasa" still looks weirder to me than "NASA" does.

Like writing "The Scsi bus went Awol" instead of "The SCSI bus went AWOL" also looks weird.

Just spray Fix-a-Flat everywhere.

Or coat the outside with a soapy water solution.

You'd think after 8 years, they'd have found the hole!

They need Matt Damon, a chopped up wooden crucifix, and some silicone caulking

The point of the rule is to not editorialize, not to keep an always-updating title.

They need Phil Swift, "To show the powerful adhesion of flex-seal, I sawed this space station in half!"

Given that the title was highly accurate at time of submission perhaps a moderator will update the title further but the submission seems to be inline with all the guidelines. This is actually also a case where I think it wouldn't be unappreciated to deviate a bit from the article title to something like Live Updates: Astronauts on ISS told...

100% and it has regularly happened in the past as live updates change the current state. Things like service status/degradation is a big one that comes to mind which is almost the same.
