The trade-off here is: When does it become more embarrassing to bring them home in the competitor's vehicle than to extend the mission further.

When in 1974 the 56 day planned mission on Skylab 4 was delayed by 24 days it was a major event.

With the current debacle we are past 65 days of a planned 8 day mission. In a past world this would have been seen as a the shame with the fact in which vessel the crew returned, being a just a minor sidenote.

whats wild is this problem never happened to the Soviet Union, and it doesnt happen to China, but its happened twice to the US now.

Why is the US giving Boeing a free pass for this? it frankly makes the US look pathetic. News stations quit covering it once the cat was out of the bag that this isnt a "routine evaluation" and the crew is actually just stranded.

23 Taikonauts in China made it to and from the Tiangong space station in the Shenzhou xx series of rockets with no issues or delays. Maybe we should ask the China Manned Space Agency for a hand?

The U.S. has launched more manned missions in the last three years than China has in the last 20.

China has literally dropped rockets on Chinese villages.

The Soviet Union treated its astronauts as disposable, and covered up many of their failed missions.

What do you consider a free pass for Boeing btw?

Looking at the three most recent Soyuz variants:

Soyuz-U had 765 successes in 786 flights. (97.3%) Soyuz-FG had 69 successes in 70 flights (98.5%) Soyuz-2 has 160 successes in 166 flights (96.3%)

Falcon 9 has 362 successes in 365 flights. (99.1%). That includes the partial failure of the CRS-1 mission, which successfully delivered CRS-1 to the space station but released secondary payloads into a lower than expected orbit. It does't include the AMOS-6 fire, which would bring Falcon 9 down 98.9%.

Falcon 9 is more reliable than Soyuz.

Tell that to Vladimir Komarov who launched on Soyuz 1 despite knowing it was a death sentence because if he refused then his close friend (Yuri Gagarin) would have to fly in his stead.

The rocket had several hundred structural problems and they knew it would fail but they launched anyways.

So he died screaming while he burned to death on reentry and he broadcasted it in the clear so that everyone could listen. And they insisted that his remains be shown in an open casket so that leadership would have to look at what they did.

Or the three backup crew members who flew Soyuz 11 and died of asphyxiation despite the fact that it was a known issue that the cabin pressure valves that led to their deaths did not reliably close automatically. Manually closing them was not part of their reentry flight plan and the only thing they got was a warning from an original crew member to do so because it wasn't safe and they wouldn't add it to the flight plan.

Challenger is 100% on NASA but the Columbia disaster was a perfect storm of small mistakes that could be individually safely mitigated (but not all together) more than a blatant failure on any one person or group in the org's part. Additionally space shuttles had experienced conditions extremely similar to Columbia's time and again without any major damage or risk to crew. It still was a failure but it was a much more complex and subtle form of failure than the Challenger disaster.

But neither of those remotely compares to Soyuz 1 or Soyuz 11. The failure in Soyuz 11 had been seen time and again during trainings and testing but was waived away and the only reason it didn't occur earlier was because of pilots unofficially taking steps to mitigate the issue outside of the flight plan that then weren't performed on Soyuz 11. And the failure in Soyuz 1 was expected from before launch. It wasn't a statistical probability that the team made a risky gamble on (like Challenger) but was a definite death sentence. Soyuz 1 is equivalent to if you had the Challenger failure but on several hundred different parts of the rocket instead of on just one.

Either way the point of my original comment was to dissuade the notion that the USSR didn't have embarrassing crewed failures in space flight, not to try and pick sides on who was worse.

Reading analysis[0] of the damage caused by a foam strike on STS-119 makes the loss of Columbia feel more "on NASA" to me than not.

Komarov was selected to command the Soyuz 1, in 1967, with Yuri Gagarin as his backup cosmonaut. refusing to fly has the same consequence for every space program: the backup flies.

Komarov: Activated, activated, don't worry, everything is in order.

Given that we at least broadly trust Russayev's recollection of events, we are entitled to believe that Komarov, for all his discipline as a cosmonaut, would have been entitled to some spitting madness and frustration."'

The US has far more deaths per flight than any other nation. There have been 19 astronauts that have died during spaceflight. [1] 14 of them have been American, with the US and USSR/Russia having a comparable number of total launches. The USSR/Russia's most recent fatality was in 1971.

NASA is paradoxical, because in terms of how they are perceived they're seen as this ultra risk averse safety-first organization, but in terms of actual behavior - they keep doing the exact same thing which has left 14 astronauts dead, and now these astronauts stranded. There just seems to be a extreme disconnect between the actual engineering staff and the managerial layer, probably exasperated by the fact that political appointees head the organization.

"NASA is paradoxical, because in terms of how they are perceived they're seen as this ultra risk averse safety-first organization, but in terms of actual behavior - they keep doing the exact same thing"

This paradox is easily resolved. As risk aversion goes to maximum, the only acceptable solution is to do what was done before. Anything we deviate from doing before is something that could fail in a new and unknown way, possibly bigger than before.

This isn't a NASA thing, this is one of the basics of large bureaucracies. It is one of the major drivers of their inertia and inability to change course. When the penalty for slightly more failure than before (in anything except money spend, that's OK as long as it's done by high level people) is expulsion and scapegoating and the reward for doing slightly better is a pat on the back and a denied request for a salary upgrade/slight promotion, you converge on having an organization full of people where this is the only path forward, no matter how much acknowledgement there is that the current situation is broken by every last person involved.

To take a really big diversion, one of the deeper aspects of the "move fast and break things" philosophy isn't just about directly moving fast and breaking things; it is creating a culture where people have permission to fail at least a little before being evicted from it. Your biggest successes will always involve some failures on the way, so if you rigorously eliminate all failure from your organization, all but the smallest, most basic of successes will go with it. It's not that you literally want to break things or that managers should necessarily create a "broken things" metric and try to keep it in some band above zero but below catastrophe, it's about making avoiding breakage not calcifying and paralyzing your company by making it the absolute number one priority above all else.

This isn't a NASA thing, this is one of the basics of large bureaucracies.

Not really, because commercial air travel had problems early on, and the FAA approach was to investigate, determine root causes, and make changes to eliminate or reduce the probability of them happening again. Assigning blame or scapegoating was not part of their process (not that it didn't happen in the media). And now commercial air travel is very safe.

Except commercial and amateur air travel seems to now be stuck in a local maxima deeply similar to what the parent talks about, avoiding risk by doing the same thing. There are good processes to improve the safety of existing operations and good reasons to keep doing proven things, but innovation is deeply choked.

See the decades long process of trying to switch away from leaded aviation fuel. Small aircraft are all running engine designs from the 1960s despite huge advances in internal combustion and fuel composition in other applications. Getting a new engine design or fuel mixture approved has proven effectively impossible, so processes have defaulted to doing things the exact same way to avoid risk.

See also the 737 MCAS debacle. Boeing was highly incentivized to keep the 737 flight characteristics exactly the same to avoid needing to re-certify the airframe or re-train pilots they invented MCAS to mimic the old behaviour and didn't tell pilots about it, leading to deadly results. Rules designed to allow change actually perversely made it a better option to avoid change (or at least avoid the appearance of change), so risk behaviour defaulted to do it the same way as before.

At this point, now that the SpaceX alternative has been officially acknowledged, I really don't see how anyone at NASA would be comfortable risking the return on Starliner. If they do and it fails and the astronauts die, everyone will be (rightly) outraged that a viable rescue plan was available and not used. It could become an existential crisis for NASA.

My belief is that the fact that they're publicly "considering" the SpaceX plan means that they've probably already decided to do that and what we're seeing in the media right now is NASA just letting everyone get used to the idea before they formally commit to it.

I gather that they're also worried that the Dragon option turns into another can of worms due to a risk that an automated return of the Starliner could result in bricking the ISS's docking port. Something about how they removed the automated docking/undocking software from Starliner for the crewed mission, for reasons I'm guessing I could not begin to fathom.

dotnet00
4 replies
1d2h

It isn't that they removed autonomous undocking. IIRC autonomous docking/undocking were part of the requirements for the commercial crew program. Starliner even did attempt an autonomous docking to the station.

The issue is that of fault handling. If the software detects a malfunction when a crew is onboard, the best option is to switch to manual control. But if a crew is not onboard, the craft should handle the failure on its own in the safest possible way.

So, what happened is that they loaded in software which expects the crew to be available. Now, obviously with thruster malfunctions already happening, they can't assume that a fault won't be detected after undocking, so they have to switch the software over to the configuration where it can no longer rely on the crew as a fallback.

pennomi

Right, but “switch the configuration” isn’t trivial, they’re estimating something like 4+ weeks of work. IIRC it’s essentially equivalent to reflashing the whole thing and revalidating the install was correct.

1d1h

I agree, what I'm trying to emphasize is that the current software is able to undock autonomously, it isn't able to handle failures autonomously. Many people seem to be thinking that Starliner had been capable of autonomous docking/undocking and the functionality had been removed for seemingly no legitimate reason. But, if we understand that autonomous undocking is present, but autonomous error handling is not, the engineering reason becomes obvious, that when you have a crew available, they're the better option for error handling than the software.

I'm not trying to make the excuse that's going around about how they don't need to change the software, just the configuration. It's absurd that they need 4 weeks for this change when switching from manual to automatic fault handling should be a basic safety contingency (it'd be necessary if the crew had become incapacitated for any reason).

I'm still not convinced this is sound engineering? Shipping two different versions of the software, instead of having some sort of switch you can flip, seems sub-optimal precisely because it increases your exposure to risks like this where you're less able to adapt to unforeseen circumstances because as soon as you wander off the happy path you're in completely uncharted waters. This feels more to me like yet another example of Boeing cutting corners without the benefit of a full understanding of the implications of the decision because their left, right, top, bottom, front, back, charm and strange hands all have no idea what the others are doing.

Someone on X was saying that NASA's definition of "flight software" includes config files. So it isn't actually the code that needs to be changed, just the config.

I think the need for 4 weeks for a config change is the requirement to test the new config in a simulator (against a long list of scenarios) and have it reviewed and approved by various engineering teams, both Boeing and NASA. Plus likely some margin added.

That may be a nice side benefit of their decision process but the driver is crew safety and data on thruster performance.

I don't see why NASA would need to manage any "Overton window." NASA loses very little if they decide to send the astronauts back on SpaceX. At worst, and this is very possible, Boeing uses this as an excuse to just ax Starliner, and NASA would be left without a secondary crew vehicle, but they won't lose funding, and their image would probably only go up since they would have made a choice in the interest of safety.

Boeing, on the other hand, stands to suffer a lot of PR and financial damage should NASA make that decision. They have an interest in managing this window. They've been lobbying NASA and tweeted something about how confident they are in Starliner, but they appear to really be on the backfoot.

The whole point is that NASA isn't "letting people get used to the idea." It's really no skin off NASA's back if they send them home on Starliner.

I want to agree, alas cannot.

I would like to believe you, unfortunately previous events show that decisions are not driven primarily by crew safety and data on thruster performance. Politics plays heavily in most decisions.

(e.g., the Shuttle was sold to Congress as a multipurpose vehicle that could support military, scientific, and commercial missions. However, the need to gain political support led to compromises in its design, particularly the decision to make it a reusable vehicle with an orbiter that could carry large payloads, which led to safety issues. The political drive for cost-effectiveness also led to the program being underfunded, contributing to the Challenger disaster in 1986.

The 'Journey to Mars' program was designed to sustain NASA's long-term goals but lacked a clear timeline, partly due to political hesitance to commit to a specific date or strategy that might not align with subsequent administrations' priorities. The program was influenced by political leaders' desires to show progress in space exploration while avoiding the high costs and risks associated with a definitive Mars mission plan.)

I'm sure if they have opinions they would share them with NASA and probably their families, and of course if it comes out that NASA ignored their concerns and they perished that would be pretty bad.

However, I imagine that part of becoming an astronaut means that you really have to get comfortable with trusting others to make critical, ultimately life-affecting decisions on your behalf all the time. So perhaps their mindset is more of "we trust that all the smart people on the ground are doing their best to make the safest decision for us, and we'll go with what you say".

If I were one of them stuck up there, though, I'd probably want to get on a video call with the Boeing engineers and look them in the eyes, show them pictures of my family, and ask if they are confident their vehicle will bring me home safely.

My belief is that the fact that they're publicly "considering" the SpaceX plan means that they've probably already decided to do that and what we're seeing in the media right now is NASA just letting everyone get used to the idea before they formally commit to it.

The messaging from NASA has slowly shifted from "They're returning on Starliner" to "They're returning on Starliner, and we're considering contingencies" to "We'll make a decision whether they return on Starliner or Crew Dragon".

It does kind of seem like NASA is giving Boeing as much time as they can to try to pull a rabbit out of a hat, with the understanding that if they don't deliver, that the Astronauts are going back on Crew Dragon.

In a past world this would have been seen as a the shame with the fact in which vessel the crew returned, being a just a minor sidenote.

I find it odd to shame NASA for what is a Boeing failure. They hired Boeing to ferry people to the ISS and back. Boeing built a spacecraft that broke down and is considered too dangerous to carry people on the return leg.

NASA is to blame for their part as responsible steward of public funds. The agency has bent over backwards, to a fault, to hand a contractor a cherry deal, papered over quality issues, performed dubious acceptance testing, made them look good for PR spinning all the failures, all while paying double vs the other (successful) vendor.

All government procurement is fraught with industry and political pressure which looks like it happened here, yet again.

Lest it looks like a one time thing, have a look at the OIG report about the SLS program perforance from Boeing, in a disastrous condition.

Oh wait, NASA has been doing the same thing with Boeing that is has been doing with SpaceX? Giving both companies the opportunity to redeem themselves from (sometimes explosive) unexplained errors while paying them hundreds of millions of taxpayer dollars to do all of it?

SpaceX lost a lot of expensive government equipment in its early days, including DoD satellites estimated to be collectively worth in the billions. (We don't know the actual value because the DoD won't say.)

With infinite time and resources anyone can.

It's a good thing the DoD was willing to keep working with SpaceX after those expensive failures. It's great to have the DoD's unlimited resources on your side even when your CEO fails a drug test that should have gotten your company barred from government contracts. (For those not in the know, Musk openly abuses marijuana, which was still illegal at the federal level in SpaceX's early days, and openly uses ketamine and other psychotropic drugs.)

In the way a rubber duck counterbalances a battleship.

Is SpaceX the rubber duck, because of all of the explosions? The Boeing is built like a battleship, and that's part of the problem: it's too complicated to diagnose from far away. Maybe if they resorted to the rubber duck method of just launching stuff and seeing what doesn't explode?

I’m not arguing we go all in on SpaceX. I’m saying we need a second space provider, and Boeing isn’t it.

Boeing is the only realistic American competitor unless Northrup and Lockheed decide to participate, but those two companies only know one way to do R&D: spend 3x your budget, then come back and ask for more. (And all of the other traditional aerospace vendors are already partnering with Boeing on this project.)

Quite the opposite. Agile is about testing ALL THE TIME and building incrementally. They have flown humans right after a single successful cargo mission. Did they have no further anomalies in the second mission? I seriously doubt it. Now they have a bunch of issues on the RCS and reentry rockets that can't possibly be entirely new (unless someone changed something and people have flown an untested critical component). Worse for Boeing, those components are procured from a third party which now they must be questioning how much QA went into them.

Based on previous articles[1], it's either return them on Starliner or bring them home as part of the SpaceX Crew-9 mission[2].

So the timeline is irrelevant to embarrassment. The Crew-9 mission has been rescheduled to 24 September, a decision needs to be done way beforehand. If the decision is bring them down using SpaceX, the Starliner crew will then stay until the end of the Crew-9 mission in March.

That is the date they will send up a half full Dragon for Crew 9 Mission, which will return home in February. They aren't changing its return date, just how many people it launches with.

Exactly right. If a bunch of thrusters don't fire up again you now have a huge piece of debris at risk of colliding with the ISS. This probably gives NASA the most pause before doing an unmanned Starliner exit. Having people on board Starliner might be able to recover from more thruster problems but then there'd also be people on a death trap. So an unmanned Starliner might be risking as much life as a manned Starliner and NASA has no idea how much.

As for your earlier question: yes. Starliner has to leave before Crew 9 can dock. And their rules are it won't launch Crew 9 until there is a port for it to dock to.

On the ISS there are 4 ports on the Russian side only compatible with the Soyuz / Progress ships and 4 for the US side. 2 are "Common Berthing Mechanism" (CBD) used by Cygnus cargo modules (and the original Dragon 1) and 2 are "International Docking System Standard" (IDSS) used by newer Dragon 2, Starliner, "and future" vehicles.

The result is that before a second Dragon can launch Starliner must leave. If Butch and Suni aren't on it then Crew 9 arrives with 2 empty seats and 2 new space suits. The contingency exit plan in between Starliner leaving and Crew 9 arriving is for Butch and Suni to lay on the floor of Crew 8 Dragon without pressure suits below the 4 Dragon crew members (their Starliner suits can't plug into Dragon's systems).

It’s not really that costly or inconvenient to extend their stay on ISS compared to Skylab though. With Skylab 4 you had to somehow figure out how to support food and water for half-again as many astronaut-days as planned but ISS has routine supply ships and a big enough permanent crew that adding two extra people isn’t a strain. From the perspective of ISS operations, having an extra two crew members more than you planned also means you can get more work done. And if you’re one of the astronauts, who has worked hard for the dream of going to space, getting a bunch of extra space days is not exactly an unwelcome surprise either. So not only is it not actually a big deal to keep them on the ISS for longer, but I bet a few people are happy to have an excuse to keep them there.

This is obviously a well-known phenomenon in software engineering and I don't think anyone here is going to be be particularly surprised that it occurs in the aerospace setting. What is a little more surprising, to me at least, is that the systems people over there don't have procedures in place to minimise risks stemming from lack of communication.

It isn't realistic for any sub-team to be fully familiar with the overall system but surely, for instance, if a team is working on component X which interfaces with components Y and Z, then it should be standard practice for the X team to spend at least some time with the Y and Z teams during development?

I'm sure that these groups are producing specifications, and I'm sure those specifications are being followed to the letter (and perhaps even being validated as such). The problem is that the spec only ever contains about 80% of reality, with the rest being lost either to implicit assumptions made by the writer, or to requirements that the implementer couldn't possibly hit and can't know (unilaterally) how to trade into something more realistic.

This is why you have to get the humans to talk to the other humans. If that communication happens via a collaborative design document then yes, that's a process, and it's one that can work.

Anecdotal personal experience in safety-critical design:

A team was tasked with modernizing their multi-million dollar decades old test stand. The entire time they were cursing previous engineers for their lack of documentation that made reverse engineering difficult. Then when it came time for them to produce the documentation on their own design, they balked at the idea. I had a conversation with them about how they are screwing over the future engineers just like they were screwed over, but they still maintained cost/schedule pressure was too much to comply. We settled on them being allowed to go forward as long as they set aside a fund source and a date to have the documentation complete. When that date came and went, the documentation wasn't done and the excuse was the funding was used up by other projects. I feel like I owe those future engineers and apology.

I don't think I'd be so trusting/naïve today and would push back harder that if they couldn't get their documentation in order when the design was fresh in their mind, they're even less likely to do so in the future.

There's a chief engineer whose job it is to oversee the project but they will be relying on the expertise of the individual teams, and each team has to work closely with and lean on their partner teams. Sometimes you'll have people who are cross-trained - I have experience in avionics, software, and ops - but that's not typical, and it doesn't take much to feel spread thin (I certainly do).

Back when I worked on this hardware/software integration, we often didn't have the hardware to test.

So we coded to the specs. I spent a lot of time reading those and trying to figure out what they meant. It was a little challenging but usually all the information was there. It worked (mostly) and we tested alot. Some stuff was strange, I still remember seeing angles in BAMs (Binary Angle Mesurements)

As a big SpaceX fan, I appreciate the innovation and success that SpaceX has brought to space exploration. However, it's crucial that we have multiple reliable launch and crew providers to ensure the safety and sustainability of space missions. While SpaceX has been a game-changer, relying solely on one provider is risky. The ongoing issues with Boeing's Starliner highlight the importance of diversity in our space program. We need to support and develop multiple providers to maintain a robust and secure presence in space.

windexh8er

You still get it very wrong.

MVP focuses on developing a product with just enough features to satisfy early users and provide feedback for future iterations. This means that the full vision of the product is sacrificed in favor of speed and minimalism. Key word: sacrificed. You don't sacrifice in a system humans are reliant on to live.

You can find this described on Wikipedia in a similar manner [0].

Compare this to a Waterfall approach - an approach that has been used in developing rigor in critical systems for decades. Waterfall emphasizes a complete and well-documented design upfront, ensuring that the final product aligns with the original vision and objectives. The end result is a fully-featured product, even if (and it will) take longer to develop.

Again... Wikipedia [1].

So, no. You don't build a mission critical system by stacking MVPs like Lego block on top of each other and then calling them "objectives". It's clear you've never built or been involved with building systems that are classified as "Safety of Life Critical System". Feel free to go review some relevant standards (e.g., ISO 26262, IEC 61508, DO-178C) and then feel free to re-justify how MVPs could be used for space vehicles that transport humans.

Keep in mind that Starliner is NOT the entire launch system. It is only the crew capsule. It rides on top of an existing rocket. The same is true of SpaceX Dragon which rides on top of Falcon 9 that already existed.

It is, and I'm curious what dang and HN's plan is wrt this issue going forward. On one hand, the "assume good faith" has been a core tenet of this community. At the same time, LLM-generated walls of text aren't good faith. And they're not going to get less common from here on out.

It's truly a rorschach test of sorts. I agree with you that there isn't enough information to say, but reading through the comment history of the commenter in question does not make it seem more likely that they are GPT. Reminds me of Fallout 4 with everyone suspicious of each other being synths.

maeil

On the contrary, the comment history makes it very clear.

Pages and pages of relatively short comments, not a single one written in a remotely LLM-reminiscent style. Then, within a very short period, multiple very long comments in exactly the default style that GPT writes in.

The chances of someone waking up some day and entirely changing their writing style might as well be zero, I've never seen it. It would be a gradual process if everyone.

I read HN every day and I think this is only the 2nd time I've come across clearly generated content. If suspicion is the issue, that should be much more frequent. On Reddit it's already more common, and I've already had multiple people admit to it when pointed out, asking "How did you know?".

It does help that I've spent the last 1.5 years building LLM-based products every day.

A few weeks ago I had a eureka moment to describe it: GPT writes just like a non-native speaker who has spent the last month at a cram school purely aimed at acing the writing part of the TOEFL/IELTS test to study abroad. There, they absolutely cram repeatable patterns, which are easy to remember, score well and can be used in a variety of situations. Those patterns are not even unnatural - at times, native speakers do indeed use them too.

The problem is dosage. GPT and cram school students use such patterns in the majority of their sentences. Fluent speakers/humans only use them once every while. The temperature is much higher! English is a huge language grammatically, super dynamic - there's a massive variety of sentence structures to choose from. But by default, LLMs just choose whichever one is the most likely given the dataset it has been trained on (and RLHF etc), that's the whole idea. In real life, everyone's dataset and feedback are different. My most likely grammar pattern is not yours. Yet with LLMs, by default, its always the same.

It also makes perfect sense in a different way; at this point in time LLMs are still largely developed to beat very simplistic benchmarks using their "default" output. And English language exams are super similar to those benchmarks; I wouldn't be surprised if they were actually already included. So the optimal strategy to do well at those without actually understanding what's going on, but pretending to do so, ends up being the same. Just in this case it's LLM's pretending instead of students.

I should probably write a blog post about this at some point. Some might be curious: Does this mean that it's not possible to make LLMs write in a natural way? No, it's already very possible, and it doesn't take too much effort to make it do so. I'm currently developing a pico-SaaS that does just that, inspired by seeing these comments on Reddit, and now HN. Don't worry, I absolutely won't be offering API access and will be limiting usage to ensure it's only usable for humans, so no contributing to robotic AI spam from me.

I'd give you concrete examples, but in the comment in question literally every single sentence is a good example. Literally after the second sentence, the deal is sealed.

There's other strong indicators besides the structure - phrasings, cadence, sentence lengths and just content in general, but you don't even really need those. If you don't see it, instead of looking at it as a paragraph, split them up and put each sentence on a newline. If you still don't see it, you could try searching for something like "English writing test essay template".

I remember that there were "leaks" out of OpenAI that they had an LLM detector which was 99.9% accurate but they didn't want to release it. No idea about the veracity, but I very much believe it, though it's 100% going to be limited to those using very basic prompts like "write me a comment/essay/post about ___". I'm pretty sure I could build one of these myself quite easily, but it'll be pointless very soon anyway, as LLM UIs improve and LLM platforms will start providing "natural" personas as the norm.

That is what happens. If a company wants to play in this sort of arena, it will not be treated "fairly" and will suffer for the mistakes of others. In a narrow two-company industry, the mistakes of either party will always impact the industry as a whole.

Think of that company that lost a submersible at the Titanic. Undersea tourism is also very narrow industry. All companies involved are dealing with the repercussions of that accident from diminished demand to potentially stricter regulations, not to mention increased insurance costs. That isn't fair, but that is how such industries work.

I can imagine a situation where I have a gut instinct that “this thing is just squirrelly, I don’t trust it.” But if I don’t have that instinctive reaction, how am I to know which return option is more reliable?

They successfully docked despite the anomalies, and it doesn’t seem to have led them to say “like hell I’m flying that deathtrap back.”

At some level aren’t everyone’s incentives, including Boeing’s, aligned around getting everyone home alive?

Sure Boeing’s risk appetite may look different, but wouldn’t even Boeing rate the loss of the return capsule as a catastrophic outcome? Wouldn’t I, as an astronaut, have priced Boeing’s incentives in to my decision not to put my foot down? And don’t I have to trust the ground team with my life before I let them strap me onto a space rocket in the first place?

Yes, flying in space is cool. No, most people don't want to do this indefinitely.

It's one thing to have a mission extended by a day, as happened to the shuttle routinely because of bad weather at the landing site. Skylab 4's mission I believe got extended by 28 days, but that was a known possibility before launch. To have an eight-day mission be possibly extended to eight months is in no way shape or form OK.

Well, they said they would do more modelling. Since they've definitely already done a pile of modelling, the remaining modelling is probably running down a list of alternate assumptions and approaches in whatever modelling system they've been using. Most likely they've already gone ahead modeled out all of their most likely and high confidence assumptions and approaches. Likely the modelling results haven't quite converged, leading them to be unsure.

In parallel, my pet theory is that NASA has probably already made up its mind (astronauts are not going to return on Starliner), and have been dragging this out mostly to make it look like they aren't just going to throw their contractors under the bus (even if they deserve it). Boeing has declared cold feet over fixed cost contracts (in general, not just with NASA), and I think NASA wants to keep the rest of the contractor pool at least at ease that, okay maybe NASA might start being stingier with the money and contracts, but they aren't going just throw you under the bus when issues appear.

The longer NASA pushes out a decision on what to do with Starliner, the more it becomes likely that people within the Biden administration don't want to go with the obvious choice of bringing home the crew on a Crew Dragon, because they don't want the resulting headlines shouting "Elon Musk rescues astronauts from space".

I think they're just being great manager-engineers just as they should be. The root-ish cause so far determined is Teflon seal soaking in rocket fuel and bulging, constricting flow. Downstream it is creating improper oxidizer/fuel ratio and excess heat at thrusters which is triggering alarm and automatic shutdown. These were all explained in plain and accessible English in NASA press conferences and I've watched it online.

I'd been a space fan for long enough that I know "improper O/F ratio" usually goes under a picture of a fireball or an artist's impression file image. There were multiple spacecrafts that at least blew off engines that way. The JAXA SLIM mission just this January had it that way. The fact that NASA/Boeing Starliner team keep triggering it and getting away with it is probably technically magnificent.

With that prior knowledge, one way I can interpret those corpospeak is "we aren't sure if we can continue to do that and not finally kill the engines, or worse yet, turn everything into a bomb with people inside or around". Many are instead receiving "we technically know such and such [unintelligible] but we aren't sure of anything and we have no idea". That's a great demonstration of public relations skills.

They're running with the theory of it being the teflon seals, but IIRC the problem is that it doesn't explain why the thrusters appeared to be operating relatively normally in a test at the station. The seal deformation should be permanent, in which case the thrusters shouldn't have recovered on their own, meaning that they might not have caught the real issue.

That's what's making the risk difficult to quantify.

NASA is paying SpaceX something like $200 million per launch. They won’t want to do that unless they have to. And if they did they still need to figure out what to do with Starliner. If they pay SpaceX and then later manage to get Starliner to work then that’s a lot of money down the drain.

Given that we're already over two months into a week-long mission, what information don't they have that they would have in another week?

As an Ars commenter observed <https://arstechnica.com/space/2024/08/nasa-acknowledges-it-c...>, it is possible that the real issue isn't whether Starliner is safe to return with humans. If that were the question two months of debate are, as you said, by itself enough to say "no". Return Wilmore and Williams on Crew Dragon. Done.

The commenter posited that the real issue is that NASA does not trust Boeing's software to undock Starliner autonomously. We know that Wilmore had to take manual control on the way up because of the thruster issues. NASA may fear that if thrusters fail again, Starliner software may again not be able to handle them, and the spacecraft might ram ISS. Thus, the agency wants a human to be able to take over if necessary. *That* is the dilemma. This is something that I and others had mentioned over the past couple of weeks, but the Ars commenter is I think the first outside NASA to put it so starkly.

They can take control over the spacecraft, the issue seems to be that the software is configured to expect crew control to be available. So, say Starliner detects an anomaly at some point, it will disable automatic control and expect crew to take over manual controls. This might cause a problem when returning without crew, even if they might be able to override that remotely.

This is not entirely correct, after all, Starliner was attempting to dock autonomously before the thruster issues hit near the station. The software is configured for autonomous undock, but not autonomous fault handling (since if a crew is available, they're better for fault handling). The software update is to enable the autonomous fault handling that is needed when a crew is not available.

"Essentially, what we're asking the team is to go back two years in time and resurrect the software parameters that are required to give automatic responses to breakouts near the ISS should we have a problem in close to ISS, which the software now allows them to do manually," Stich said. "The team is always updating these mission data loads as different things change."

I mean, it makes sense that if you have a crew onboard, you want to make the crew handle the cases when the software thinks something is wrong. Similar to how plane autopilots will disengage for many kinds of faults.

If you don't have crew onboard, you don't have any choice but to rely on the software's judgement.

I think the big problem is that the changeover is going to take several weeks, since Starliner should be able to fallback to flying autonomously if the crew happens to become incapacitated for some reason. The changeover should've just been a matter of sending a command from the ground or via a relay satellite.

Eric Berger—Ars Technica reporter who wrote the article SimpleFlying cited—initially reported that Starliner needs a software update that will take four weeks, and NASA (I believe Ken Bowersox) worded it in the penultimate media event as reverting back to the 2022 software, but we now understand from context that in this case that means reverting to the 2022 parameters; NASA was very specific about the software itself not having changed.

The SLS[1] stans (as Berger described on Twitter) are now focusing on how parameter change != software update thus Berger was wrong all along. It'd be one thing if said changes took a day or two to do. But assuming that it is the four weeks Berger reported, that absolutely means that it is the same thing as "software needs replacing"/"functionality was removed". To the client, NASA in this case, it doesn't matter whether the weeks to implement a new feature is (one week of uploading parameters and three weeks to validate said parameters), or (3.5 weeks of uploading new software and 0.5 weeks of validating said new software). The end result is needing four weeks.

It's intriguing to me that they seem to be prioritizing information collection to determine whether Starliner is viable, as opposed to definitively announce a return via SpaceX and making preparations for that.

It's like if I have a service outage, maybe I might spend a few minutes to collect debugging information, but my priority would be to bring the service back up via rollbacks or whatever to restore a previously known good state. Currently they are debugging Starliner with people stranded, but maybe they should prioritize on getting those people back home first.

Or maybe everyone involved don't consider being stranded for months in space as a bad state.

I think for part of your question (why do they specifically say a week), the length isn't all that meaningful. As in, if they want to more time to make a decision, they'll just announce another week's delay.

I wonder sometimes whether NASA should lean into the high risk of spaceflight instead of trying to minimize it. If they could get the public to pay attention, their budgets would go up. Highlighting the risk--without exaggerating--would be a good way to get people to care. People love (maybe even crave) drama.

Astronauts accept an amazing amount of risk, even when using proven systems like Soyuz or Dragon. ISS is one unlucky micrometeoroid strike away from total catastrophe. And yet hundreds of astronaut candidates are jostling with each other (another great drama) to be next on the rocket.

Even uncrewed missions are filled with drama. Imagine devoting 20 years of your scientific career on a probe to Mars and having it blow up on take-off or smash into the Martian surface--so close, and yet so utterly useless.

I think NASA fears that highlighting risk leads to bad press. NASA doesn't want headlines like, "NASA ignores safety concerns--story at 11". But ironically, when NASA minimizes risk, they lower the threshold for how much risk the public will accept. The more they minimize risk, the less risk the public will let them take.

I don't have any good suggestions, though. Highlighting risk inevitably invites the question of "why are we taking the risk at all?" And that's also a hard conversation.

"Film at 11", "Pictures at 11" or "News at 11" is a US idiom from television news broadcasting, in which viewers are informed that footage of a breaking news story will be screened later that day. The word "film" in the phrase dates back to the early decades of TV news when footage was regularly recorded on film.

Film, here, seems especially dated. Sometimes anachronistic idioms get modernized rather than remaining static.

What's particularly interesting is that idiom is not just anachronistic, but that it's been through several evolutionary obsolescences: film -> tape -> digital -> internet / social / streaming / VOD.

That feels like a retcon, for lack of a better word. I'd like to see a clip of "news at 11" being used that way by an anchor in a news broadcast (especially pre-1980).

Edit: I think the term that covers what I'm talking about is folk etymology: https://en.wikipedia.org/wiki/Folk_etymology:

Folk etymology – also known as (generative) popular etymology,[1] analogical reformation, (morphological) reanalysis and etymological reinterpretation[2] – is a change in a word or phrase resulting from the replacement of an unfamiliar form by a more familiar one through popular usage.[3][4][5] The form or the meaning of an archaic, foreign, or otherwise unfamiliar word is reinterpreted as resembling more familiar words or morphemes.

My theory is that:

1) Delayed available of footage due to film technology created the "film at 11" idiom, which became so ubiquitous it was the basis of jokes.

2) "The phrase was used in many TV shows and movies from the 1960s through the 1980s."

3) Film was replaced by video at some point prior to 1980 (guess). The idiom ceased being used in news broadcasts, and became unmoored from its foundations but continued to drift around in popular culture.

4) People ignorant of the origin use "folk etymology" to mis-correct/twist "film at 11" to "news at 11," which fits the pop culture formula.

5) "News at 11" gets repeated all over the internet all the time.

NASA is a fundamentally political organization. Given that it's political the risk isn't worth it.

Once that driving force was gone there was no longer an appetite for risk.

And even look today, look at the relatively small risks (minor environmental rule edge skirting) SpaceX takes with unmanned test vehicles (Starship) and how much they're completely and constantly raked over the coals for it. The media in the modern era only knows how to attack and criticize.

High and low are quantifiable risks. Starliner risk is a divide by zero error NaN instead of a value.

. . . as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don't know we don't know.

They're being downvoted because they're intentionally misreading what "pressured to perform" means in this context.

Both space shuttle disasters occurred because NASA was under pressure to 'perform' in the sense that they were under pressure to increase launch rate and cut costs to the extent that safety concerns were overlooked. Potentially serious issues were overlooked in favor of just flying.

Similarly, the concern here is that NASA management felt pressured to allow Boeing to put the lives of crew at risk despite serious safety concerns from engineers. While they would've lucked out in this case since they got to the ISS and have alternate ways to come back, if that turned out to be the case, it'd raise serious additional concerns for NASA's management of other Boeing programs (see: SLS and Orion).

As a taxpayer funded entity, NASA should feel pressured to perform in that they should feel pressured to progress their mission as efficiently as possible. This means taking the time to properly weigh safety risks, as a crew vehicle exploding due to known problems is a waste of taxpayer funds.

NASA wouldn’t need to be fully vertical, but it would be wise to have as few nested contractor interfaces as possible.

Another important thing is that their jobs should be protected from political interference, so that nobody feels compelled to not speak up.

The spacecraft's already built with a (large) surplus of thrusters—the extra thrusters are all right there, pre-attached. It's because of that safety margin that NASA relaxed their requirements and launched with thrusters exhibiting high failure rates in testing.

Redundancies don't help you if you have a safety culture that treats redundancies as consumables. The more one team widens a safety margin in one place, the more another leans on that safety margin, and relaxes their own.

They have a lot of sensors on everything, plus they'd be filming from a lot of angles, and the additional benefit of ground testing is that they can look at the debris. You can piece together where the explosion happened based on the charring and where the parts broke and how.

If I recall correctly, the Dragon explosion was especially interesting because the reaction was previously unknown. So, it wasn't just a design flaw that allowed NTO to leak into a helium line, it was also a new discovery that titanium can react with NTO under high pressure and ignite.

At some level by covering or Boeing they are covering for themselves. They were the ones putting the astronauts on it, after all.

But there is another level: there some kind of a background hate directed toward Musk and Space X. Someone in government agencies is asking themselves, how could we put some sticks in Musk's spokes? Some ask him to kidnap seals and put headphones on their heads [1] or calculate what's the chance his rockets would hit whales in the Pacific Ocean [2]. So it's not that they particularly love Boeing that much, but if Boeing's success makes Musk's company look worse, fine, then they'll support Boeing.

Imagine a scenario, for a moment, that the situation is reversed. Space X is the capsule with the issue and Boeing is the one with the cheaper and working version. There would be no hesitation to pointing fingers and accusing Space X make a large media stink about it instead of covering up.

Whether the seals would be dismayed by the sonic booms. Now, there’ve been a lot of rockets launched out of Vandenberg and the seal population has steadily increased. So if anything, rocket booms are an aphrodisiac, based on the evidence, if you were to correlate rocket launches with seal population. Nonetheless, we were forced to kidnap a seal, strap it to a board, put headphones on the seal and play sonic boom sounds to it to see if it would be distressed. This is an actual thing that happened. This is actually real. I have pictures.

[2] https://lexfridman.com/elon-musk-4-transcript/

Now, again, you look the surface, look at the Pacific and say what percentage of the Pacific consists of whale? I could give you a big picture and point out all the whales in this picture. I’m like, I don’t see any whales. It’s basically 0%, and if our rocket does hit a whale, which is extremely unlikely beyond all belief, fate had it, that’s a whale has some seriously bad luck, least lucky whale ever.

Just to make it clear, I don't like Musk, I don't have any stock in his companies, and don't buy his cars or use twitter/X. But it's still interesting to observe this effect of cover up and strange push against Musk.

It is not strange at all the inefficiency of the government has compounded to an extent such that even the military can not produce weapons to standards. SpaceX is one of the few shinning beacons of the Pax Americana if they kill SpaceX and continue to support these dying businesses without stringent reforms or refuse to allow their competitors China will overtake us. You can already see this happening where NASA of today just moves money from the government to private companies(but the ones truly doing innovation and delivering are the private companies) the technical capabilities of NASA now exist in the past while the China National Space Administration has been steadily improving their technical capabilities while also supporting a burgeoning private space industry. The financialization of US economy is making it such that those that produce money with the least actual value are being prioritized, while it different in China. The engineering legacy is already gone substantially, we cannnot even produce naval destroyers to spec even after multiple delays and after being overbudget, while China is cranking out better and better ships and using the engineering legacy of ship building to make naval destroyers. The Naval battlefield has changed whereby the previously overpowered aircraft carriers are now a huge liability with a missile costing less that $200k can destroy it (while there was a lot of spending on counter measure like the phalanx) the future is no longer of large ships.

Can you guarantee that hitting the "undock and re-enter" button right now would result in Starliner safely leaving the ISS and then clearing its orbit?

Even if that had an acceptable level of risk, that still leaves two extra crew on the ISS with no seats home in case of an emergency, and NASA's policy in recent years has been to always have emergency return capacity for every crew member onboard.

I'm not saying there isn't a path forward that involves sending Starliner back empty, there are just a lot of considerations going into that decision right now.

IIRC they usually keep an extra 3 months worth of supplies available at the station, to allow for delays to resupply missions. A resupply mission also arrived at the station recently, which would have had additional supplies for them.

If they decide to go with the plan of sending a reduced crew in Crew-9, they'll probably add extra supplies to that too. So, supply wise there shouldn't be any concerns.

It's a little more nuanced than that.

If NASA decides to bring the Astronauts home on a Crew Dragon, there will be a short window of time between when Starliner undocks and when the next Crew Dragon docks that there will be 6 International Astronauts on the ISS and only 4 seats.

If an emergency happens during that time, NASA would jerry-rig some extra seats in the existing Crew Dragon and bring all 6 home that way. But that's a very short period of time - just a couple of weeks.

The next Crew Dragon will only have 2 Astronauts aboard, and will contain suits for Butch and Sunny, so that all 4 of them can return normally on that vehicle at the end of the next rotation.

negative_zero

The limitation is both ISS scheduling (it's very busy now and has been for a while) and number of available docking ports.

It's part of why the next crew dragon mission is being delayed, it needs to use the docking port currently occupied by Starliner (and Starliner can't leave until Boeing updates and uploads software for full autonomous operations).

dotnet00

As others have mentioned, he hasn't needed to suggest it because that's the official alternative anyway.

The next Dragon crew rotation is coming up in September, so the current proposed plan is to only send 2 people up, along with the Dragon IVA suits for Butch and Suni, and bring them back when that crew rotates back out in February.

SpaceX (afaik) also doesn't have any spare Dragons available for an extra rescue mission right now. One is set to fly their EVA test flight in a week or so and does not have the hardware to dock with the ISS, instead replacing it with an EVA port. A second Dragon is being prepped for a crewed polar flight sometime later this year, and a third one is likely in the process of being refurbished for the crew rotation in February.

But also, they can't dock a second Crew Dragon at the station until they undock Starliner, and that is its own can of worms right now (needs a few weeks to update the software for uncrewed operation).

It's an obvious conclusion at this point but there's a lot of pressure to decide otherwise because of the financial and political stakes. The core issue is that NASA and Boeing know this and don't want to sign off on this. But they also don't want to sign of on the failure of the mission just yet; having signed off on the launch already. So, they are a bit stuck here.

Fortunately, running down the clock makes this a foregone conclusion. A lot of the components and systems on this thing have expiry dates. So, they are running down the clock. And of course the longer that lasts, the more potential for new problems there is.

By simply running down the clock, they get to land the thing without passengers and without having to do so because of the original failure. So everybody saves face (somewhat). My guess is they'll try to land it normally without passengers to "validate" it at least worked as advertised. But without risking astronaut lives. And then dragon swoops in and it's business as usual and nobody died.

The difference between Dragon and Starliner is that Nasa used Dragon for years without passengers so they knew the thing worked as advertised. And then the first launch with passengers was a non-event in terms of safety as it was just another launch for them. It's what SpaceX does: iterate lots until they can nail it every time.

The issue with Starliner is that launching it is too expensive to do this. No reusable rocket means they need a new one every time. So, this is only the third launch they've attempted. And the previous unmanned launches had lots of delays and issues. Technically they've never had a flight without problems.

They never had a lot of confidence building launches without passengers because the cost for that would have been astronomical. So, it's a big question mark in terms of safety. And all the constant incidents involving Boeing aren't instilling a lot of confidence.

So, they are simply running down the clock until failure is a foregone conclusion. The pressure is on Boeing to guarantee safety to NASA. And there's no way that either of them is signing off on a manned return of this thing because they'd never hear the end of it if it goes wrong. Which is why we're getting all these euphemistic statements about hard to quantify risks to explain why they can't sign off.

sitkack

Yeah, and the fact that is gone on so long without them throwing a bunch of shit into Starliner and sending it back down with a whole lot of telemetry shows just how much clothing the emperor doesn't have.

They went and made it political.

This isn't directed at you, for you, I wish could actually pay you for your response.

SpaceX has one thing going for it and it is iterate and gather data. NASA used to have this, and then they lost it. When shit becomes "important" it also becomes ridiculously stupid. We need to figure out how to make things not important.

Quantification of reliability and risk of entire systems like spacecrafts is a real activity in aerospace engineering (probably in other safety critical fields too). They take the reliability figures of every single component based on experience, and use them to progressively calculate the reliability up to subsystem and full system levels. From this, they can assess the probabilistic risk involved.

Granted that these figures are theoretical and probably varies from reality by a good margin. But these figures are still useful. For one, these figures are updated, recalculated and refined as more actual figures are obtained from components, packages, subsystems and system level tests. The final reliability and risk figures progressively approach the actual values as more tests, including flight tests are conducted. In addition, even preliminary figures help you identity potential risks and mitigate them with better engineering margins, redundancy, better test methodologies, etc. In other words, the quantification helps you contain the risks much better than any qualitative analysis.

In this particular instance, NASA's statement is concerning because it would mean that they don't the reliability figures for many components and/or don't have the reliability assessments based on tests.
