Super exiting.

* JWST costs ~$10B, about the same as Large Hadron Collider or aircraft carrier.

* JWST has 344 single-point-of-failures (SPOF), 80% of them related to deployment.

* No ability for repair. JWST goes to orbit the Sun 1.5 million kilometers away from the Earth, almost 4 times the distance between Earth and Moon.

* Ariane 5 launch failure rate is 0.045

---

assuming 0.045 launch failure probability, and 0.0001 failure probability for each SPOF, the mission failure probability is ~8%.

  0.955×(1−0.0001)^344

⬐ guerrilla

> 0.0001 failure probability for each SPOF

Why did you choose this value for the assumption? Is that standard or a publicized detail?

⬐ nabla9

I picked relatively high number 1/10000 as a starting point to get a ballpark. NASA has never tested deployment in the zero gravity. It's unlikely that the probability is higher.

Ariane launch failure probability dominates if you add zeros.

  0.00001  -> 4.8% 
  0.000001 -> 4.5%

⬐ efitz

I’m much more concerned about what will happen once the telescope is in operation. We can’t send astronauts to L2 to fix it like we could send them to Hubble on STS.

⬐ pfdietz

We can't yet, but doing so isn't entirely out of the question. It's easier than sending anyone to Mars. The one-way trip time for astronauts to L2 might be 25 days.

JWST apparently does have some kind of docking attachment so we can service it if we get the capability between now and EOL. Servicing once could likely double its useful life. Starship and Orion could do it AFAIK. Maybe Dragon with a service module.

⬐ mlindner

The docking attachment was originally planned but there's been no mention of it in the last 10 years or so and no pictures of such an attachment point. They probably de-scoped it.

⬐ redisman

I’m guessing they can’t service it by adding more fuel? That would’ve been a neat expansion to be able to expand its life

⬐ dredmorbius

The possibility has been engineered, though the mission profile does not rely on this.

JWST does have a docking ring: https://www.space.com/3833-nasa-adds-docking-capability-spac...

From the broadcast: "Liftoff from a tropical rain forest at the edge of time itself."

It was “to the edge of time itself” which I guess is some kind of reference to the telescope being able to observe the early universe? It seemed kind of cheesy.

⬐ 95014_refugee

It means that someone was paid to talk, because radio dies hard.

The idea that commentary should be informative and that content can speak for itself is (still) deeply threatening to many folks in the broadcast industry. See any sports broadcast for examples.

It is 'to the edge of time' and what they mean with it is that the JWST can look very far back into our past to the earliest days of the universe with its instruments that are capable of observing severely red-shifted wavelengths.

Good launch.

And over 472k viewers on the livestream. Good service by YouTube.

(I don't get to praise them often, credit where due.)

All launch events seemed precisely on schedule and trajectory.

The 2nd stage even caught the solar panel deploy on camera, which I believe was an unexpected bonus.

Now we've got 30 days of deployment events, another 300 or so SPOFs to clear. Arrival at L2 in a month.

Six months to chill and calibrate (with or without Netflix I'm not sure).

Science starts in June.

⬐ kurthr

I was a little disappointed, because I'd watched the animation last night.

The only differences were in the first 4 seconds (before it hit the clouds) and after the spring launch, when we caught the solar panel deploy in the sun with earth below from the 2nd stage. At least everything went as planned!

I was surprised at the timeline and how rapidly it slows before reaching the L2 orbit. It's already fallen from 4mps to 1.7mps in the first few hours. Even though it takes 30 days to reach L2, it will be 30% of the way there in the first day.

https://webb.nasa.gov/content/webbLaunch/whereIsWebb.html

⬐ dredmorbius

The difference: today's event relied on the animation to show planned mission phases.

And was accompanied by confirmations that those phases had in fact executed according to the plan.

The live shots of the JWST and solar array deploy were bonus.

Clear skies would've been nice. A good flight beats that though ;-)

⬐ 1_player

From my limited understanding of orbital mechanics from playing Kerbal Space Program, the furthest point of the orbit (aphelion) is where you reach minimum velocity. So to leave the Earth, you accelerate a lot (the so called burn) so that your orbit grows and as you get there your speed has been decreasing the whole way, and it increases back again after passing aphelion on your way back to Earth (perihelion).

⬐ 1_player

We had about 11K on STS 82, which I still think was the high point of my career. Back in the day with capacity being what it was that put a serious strain on the internet as a whole, shortly after that we had to move to the other side of the Atlantic be able to continue to operate.

⬐ mjsweet

My wife is an astrophysicist here in Australia and had been looking forward to this launch for over a decade. She plans on using James Webb and gravitational lensing to observe galaxies at extremely high redshifts. Basically one looks behind single or clusters of closer galaxies for very young galaxies in the early stages of forming, not long after the Big Bang. The gravity well of the closer cluster acts as a giant lense, acting as an additional optical element to the telescope propelling us even further into the distant past.

As we watched the launch I asked her what James Web means to astronomy. Her answer? "It will fundamentally change what we know about the universe".

⬐ savant_penguin

This is amazingly exciting

Would she know about any list of projects that intend to use the new measurements?

⬐ mjsweet

Do you mean an observation schedule?

⬐ savant_penguin

I mean projects that are going to use the data. An observation schedule would be cool too.

I was thinking something in the lines of:

"We'll test hypothesis y by observing x, that would help us understand whether theory A or B (or neither) is right"

⬐ rnoorda

It's always inspiring to see what can be accomplished by large groups of people working for years and years to create things that have never been made before. And then the elation of success, after years and years of work, delays, and more work.

Watching the launch made me feel the wonder of spaceflight I felt as a child- and the holiday timing felt even more perfect.

⬐ melling

Yes, it has been in the works for a long time.

“Development began in 1996 for a launch that was initially planned for 2007”

“Construction was completed in late 2016, after which an extensive testing phase began”

https://en.m.wikipedia.org/wiki/James_Webb_Space_Telescope

While it’s great that it’s finally up, we should re-evaluate why it takes such a long time to develop these projects.

The pace of innovation appears to have slowed greatly in recent decades.

⬐ scrozart

I am still surprised when people underestimate the absurd complexity of this project.

This is a novel masterpiece of science and engineering, not a jet fighter or rocket destined for mass production and deployment. There will only ever be one, so there's literally zero room for error. Better to measure twice and cut once, so to speak.

These projects are subject to incredibly rigorous post-mortem investigations, and each cost and time overrun is _already_ documented thoroughly and publicly. Congress doesn't give this money away lightly. We know exactly why, and when, things took longer than expected, and those lessons learned are already being applied to subsequent observatories like Roman.

⬐ bostonsre

It's a ridiculously complicated machine built to peer into the beginnings of the universe and sniff out indications of life across our galaxy. I think people could cut them a little slack. I'm sure they had amazingly complex issues and obstacles to overcome.

⬐ nyolfen

it took 3x+ longer than the apollo program took to put somebody on the moon

⬐ nkrisc

So what? Was the Apollo program more complicated than the instruments on JWST? They are two very, very different missions with different requirements. In many ways, each mission is unique in its own ways and I don’t see much value in comparing them on such basic metrics. Why is the time it takes important?

⬐ ardit33

Absolutely yes. The apollo's feat, of landing a lander in a different body, with people in it, and making sure that lander lifted off the moon, and got back home safe was astonishing accomplishment.

Especially with the rudimentary computers and calculations of the time. The James Web Telescope, is a great feat, but not in the same league as the moon landings.

⬐ 1_player

Given that Apollo landed on the Moon during the Cold War and the space race with Russia, it's incredible what injecting a percentage of the US defense budget into NASA can accomplish.

⬐ nkrisc

> not in the same league as the moon landings.

Why not? It seems an amazingly complex bit of engineering. The Apollo missions are impressive in their own right, but are they really that much more complex from an engineering perspective? The tolerances and precision required for JWST to be functional must be incredibly tight.

⬐ mendigou

Apollo was amazing and the feat in guidance and navigation computers was astonishing. No one will dispute that. But let's not glorify it and discount all present missions.

Building an observatory is VERY difficult. Nevermind the "avionics" for an L2 mission, the manufacturing of the sensors, mirrors, and all the other mechanical parts are one-of-a-kind.

Webb is without a doubt an amazing feat of engineering and the engineering teams had to confront problems that were not even thought of for Apollo. Massive respect to them.

⬐ nyolfen

once again, not a moral claim or even disputing that apollo was exceptional — but that does not change the fact that this reflects a slower rate of innovation

⬐ mendigou

Yep, I agree. I was replying to my parent comment that said Apollo was more complicated than Webb. I think they are very different amazing missions that you can't compare.

⬐ nyolfen

it supports the OP's statement that the rate of innovation is slowing down, it's not a moral claim

⬐ kibwen

No, the rate of funding is slowing down, and unlike Apollo there's no political urgency to the JWST. With 5x the funding you could afford to have less stringent manufacturing and verification (resulting in less cost-per-telescope and build time) and just accept that even if one of the telescopes fails, you can just build and send up another (or another five).

⬐ nyolfen

these are not mutually exclusive claims

⬐ nine_k

I suppose Apollo spent significantly more money, measured as a part of the US GDP. It was done in a lot of hurry.

⬐ kibwen

> It was done in a lot of hurry.

Indeed, we must keep in mind that the tolerance for failure was higher even as the cost of failure was higher. Do not forget the astronauts taken by Soyuz and Apollo.

⬐ kortex

Apollo also cost $280B inflation adjusted, so like 25x. And Apollo was a mad dash, with many risks taken. JWST is slow and steady. Like I'm a space buff and even I was pretty surprised when I learned how cowboy the moon decent in particular was. They had one shot, and had to fly the lander by hand, without any actual experience (they had to rely on a super cool craft which offset the weight to act like 1/6g).

Like... Apollo was utterly bonkers, bordering on full-Kerbal, in so many ways. It cost lives (5 training flight accidents, 3 in Apollo 1 fire), almost lost another 3 in Apollo 13.

JWST is proving out tons of new science and technology, but at a much more pedestrian peace.

⬐ marcyb5st

We are slow because we need to send stuff in orbit and so they need to survive launch and fit into the launcher. That adds 99% of the complexity.

If, instead, we would build stuff in orbit it would be much cheaper and faster as you don't need origami like folding, high Gs resistance, and a malfunctioning piece can be replaced easily.

⬐ simion314

>If, instead, we would build stuff in orbit it would be much cheaper and faster as you don't need origami like folding, high Gs resistance, and a malfunctioning piece can be replaced easily.

I am expecting still is much more cheaper to create bigger rockets then move the factories,the workers and everything they need in orbit.

⬐ m4rtink

Near term - yes, long term you want to use those rockets to put the people, factories and general infra in place to build the really massive telescopes, in the hundred meter to kilometer size categories.

Not to mention crazy long range VLBI radio setups or telescopes at the edge of the solar system using the gravity lensing of the Sun to observe things.

⬐ simion314

>long term you want to use those rockets to put the people,

Sure, maybe in very limited capacity, like why not build stuff in giant parts like giant lego blocks on the planet and have some robots and a few people assemble it in orbit.

Rather then have 10K people work extremely inefficient and dangerous in zero gravity(I am assuming you mean we capture asteroids and we build stuff from bare minerals up). Imagine what extremely expensive factories you need that work in zero gravity(things fly everywhere at a small bump) , so maybe first we build a giant rotating space station using parts made on Earth.

In the long term we should have better rockets , maygbe we pt a space station in the important points in our solar system and send them this big lego parts so they can just assemble them.

Personally I see no way humans can live and work more efficient in space compared to live and build stuff on Earth and pay some guys to build big rockets and move the stuff into space, even in long term. What we are missing today is the ability to have guys present when the telescope unfolds to help with problems and manually do fine calibrations, if we could have that we could build a giant mirror made from small parts and have people just help connect the parts

⬐ sobkas

> If, instead, we would build stuff in orbit it would be much cheaper and faster as you don't need origami like folding, high Gs resistance, and a malfunctioning piece can be replaced easily.

Are you sure it would be cheaper? Building orbital build facility would be so expensive. Housing staff to build in the orbit or investing in robotics isn't cheap (or possible) either. So it's cheaper to include hardening against high-G launches than build orbital facility for the amount of launches that need this kind of preparations.

⬐ yardie

There is building stuff in orbit and there is learning to build stuff in orbit. We’re still figuring out the later. Microgravity factories and construction have many benefits. We just haven’t figured out the how just yet.

⬐ melling

The construction was finished in 2016.

It’s not just this project, NASA, for example, hasn’t had the capability to put humans in space since the Shuttle retired.

Anyway, we are all aware of the Manhattan Project, Space Race, SR71 development, …

Someone mentioned this book yesterday, maybe it has some of the answers

⬐ m4rtink

Well, the capability is back now with Crew Dragon and maybe even Starliner eventually.

⬐ cletus

A better lesson to take here is second system syndrome [1].

JWST took so long because it was so ambitious. Hubble has a 2.4m mirror. JWST has a 6.5m mirror. No rocket can launch that fully assembled so you've automatically added a bunch of complexity to unfurl and assemble that in space.

There's a whole bunch of other new things that simply have never been done before. Any one of these is a challenge. Doing them all at once with almost no margin for error and no possibility of intervention and repair drastically increases the complexity and cost.

Another example: the instruments are so sensitive that after fairing release it has to be rotated to keep them away from direct sunlight. That'll continue on the journey to its final orbit.

Also the sunshields are tennis court sized.

It is mind-bogglingly complex.

Arguably what they should've done is launch something slightly less ambitious sooner.

[1]: https://en.wikipedia.org/wiki/Second-system_effect

⬐ ridgeguy

Important goals can take long efforts to achieve. For something as novel and complex as JWST, I don't find its quarter-century development time surprising or odious.

Cathedral Notre Dame was begun in 1163, took 182 years to complete. We moderns recognize it as a thing of beauty (pre-blaze), but I'm sure it was a tour de force for technology of the times, with many unexpected problems that delayed the project.

I'm glad each project's sponsors saw them through to completion. I hope humanity continues to sign up for hard goals that take time to reach.

⬐ beefield

> The pace of innovation appears to have slowed greatly in recent decades.

Nope. We as a society have just re-evaluated what is the innovation we want. In the old days it was moon programs and nuclear technology (for good and bad). Later we deemed circumventing financial regulation and getting people click ads more important.

⬐ MomoXenosaga

⬐ el_nahual

The skillset required to do Difficult a Thing, Fast is independent to the skillset required for being a smart scientist.

Moving quickly requires very specific managerial skills & risk appetites.

Legacy scientific institutions (like NASA, or most universities) have basically succumbed to extreme Peter Principle: everyone has been promoted to their level of incompetence. Excellent thinkerw can make catastrophic managers.

This is a known issue in startup land, and mitigations have a been learned. Examples: independent, deep career paths for mangers and contributors. A funding model that is milestones based with minimal barriers to entry.

SpaceX of course being some sort of proof in this regard.

It's not just NASA of course. Look at ITER--a fusion project started in 2007 with an expected completion date of 2025. Or the Second Avenue Subway, or any number of infrastructure projects.

If you wrote a company manual designed to maximize the odds of failure, you'd end up with something pretty close to the way academic and govt projects are run.

⬐ JaimeThompson

Doing things the first time is always more expensive then doing them the 10000th time even if the 10000th is slightly different than the 9999 before it.

Project like Webb and ITER are doing things that simply haven't been done before which makes it much more difficult. They are also beholden to politicians for funding.

⬐ snowwrestler

The problem with this comparison is that most people don’t know enough to understand how much more difficult a project like ITER or the James Webb telescope is than what startups try to do.

Did we truly slow down :D Maybe americans have become biased, but as a French, just launching this thing in a machine that can launch 80 successive and productive payloads in space is a positive sign of progress compared to how far our country was 2000 years ago compared to its peers in Asia and Africa.

⬐ marcodiego

Targets get constantly closer to physical limits, that makes pace of innovation always decelerate. I can only see 2 situations where pace of innovation accelerates: a new discovery like was the transistor or a new area of research like was with the radio.

⬐ dredmorbius

There are innovations which feed back on themselves, usually involving greater precision or density. Microprocessors are the cononical case, where reducing the size of transistors reduces distances, energy requirements, heat management, and increases (to the square) component density enabling more capacity in the same volume.

The picture becomes rapidly less impressive when we look at where that processing goes, in many cases much of it is consumed with processing that's not directly related to useful output, though one area that has benefitted greatly has been usability: a computer user used to be a very highly skilled and trained position, now infants and those with severe cognitive or other impairments can make productive use of computers --- a lot of processing power goes into simply expanding the potential user-base.

(This isn't a slight or dig at who computer users are at present, though I admit some frustrations with how this transforms mass-market platforms, devices, and software away from power-user capabilities and interests.)

Network-dynamics systems (which microprocessors arguably are) can also see similar types of dynamics, at least over a range of scale.

In many other domains though, the engineering possibility frontier is one of sharply diminishing returns, after even only a fairly trivially small amount of initial progress. Occasionally there are bursts of progress, often as two separte areas of technological develoopment are integrated together, but even that often provides only a brief period of high returns.

What I see lacking is even a rudimentary model of what domains within technology do and do not afford for accelerating returns to scale, or what the bounds and limits of the exceptions might be, or what the actual delivered net benefit of such accelerating returns might be.

⬐ krallja

Machining (specifically, lathing) is an even earlier example of improving precision feedback loops. See “Machine Thinking” on Youtube, very well produced and entertaining.

⬐ dredmorbius

That's an excellent channel, I've watched a number of the videos and strongly second the recommendation.

Precision generally is an area of positive feedbacks just as you describe. I only know a small amount about the practices, but the ability to measure and control with high degrees of precision have brought forth a tremendous set of advances, microprocessors being amongst them, but hardly the only.

The pharmaceuticals industry relies on precise control over feedstocks, process, consistency, and logistics chain (especially where temperature-controlled distribution is required).

Metallurgy similary developed with control over the quality of feedstocks, temperatures, pressures, and overall processing, as well as the ability to directly assess outputs, crystal structures, and the like.

Microsurgery relies on tools, sensors, and measurement, as well as coordination amongst a surgical team.

Tunnelling and mining can now occur with phenomenal precision through solid rock.

That's just a handful of examples off the top of my head as someone outside the field. I'm missing numerous highly notable examples I'm sure.

⬐ barkingcat

some things are worth taking their time.

⬐ tibyat

⬐ gameswithgo

The pace of innovation should slow, as innovations become increasingly more difficult. The low hanging fruit naturally is discovered/built first.

Fusion power harder than Fission, Webb harder than Hubble, bigger particle smashers harder than smaller. Sometimes earlier innovations allow you to accelerate the next innovation but eventually you get diminishing returns.

We older tech and science nerds need to be careful not to fall in the “kids these days” traps. The kids are allright, the innovations of the past were full of chaos irrationally and mistakes as well.

⬐ geenew

Serious question, if the sun shield does fail for some reason, would the telescope still operate but just at reduced sensitivity? Asking to the infrared astronomers out there…

⬐ jacquesm

Not an IR astronomer, but this is a 'no'. The delta between the 'hot' and the 'cold' side of the telescope is very impressive if the sunshield is working, without that the mission would be a failure because the IR sensors need to be that cold to work. You might still get some visible light work done but the IR part of the mission would be over because the sensors would effectively be blind.

For reference:

https://www.inverse.com/article/42894-sunshield-rips-keep-ja...

⬐ jacquesm

I read some more about the effect of sunlight on the telescope structure and the optics. They would actually be damaged beyond use by direct sunlight, which is one of the factors that they had to take into account when launching the JWST:

"The James Webb Space Telescope is launched on a direct path to an orbit around the second Sun-Earth Lagrange Point (L2), but it needs to make its own mid-course thrust correction maneuvers to get there. This is by design, because if Webb gets too much thrust from the Ariane rocket, it can’t turn around to thrust back toward Earth because that would directly expose its telescope optics and structure to the Sun, overheating them and aborting the science mission before it can even begin. Therefore, Webb gets an intentional slight under-burn from the Ariane and uses its own small thrusters and on-board propellant to make up the difference."

This is a very delicate machine.

⬐ beerandt

Think of it as the body of a camera cracking. Some amount of light will leak in and expose the film/sensors. Just depends on how much.

⬐ jacquesm

That analogy only works for a small part, the light would not do damage if it didn't fall on the film or sensors directly or through reflection, whereas with IR it doesn't really matter where it falls on the telescope it will cause the whole thing to warm up and the rejection mechanisms can only cope with so much of it.

⬐ terramex

Not an IR astronomer, but enthusiast astrophotographer. As I understand it there is a bit of leeway in the sunshield. They added strips of "duct tape" going across layers to prevent potential tears from spreading and telescope can still achieve full science power with few tears in the sunshield, depending on their location and sizes. With bigger tears it might be possible to still carry out observations in visible spectrum and near-IR but not in mid-IR as thermal radiation would crush the signal. Mission would still be considered failure in that case.

⬐ mkmk

Here are most of the big ones, with timing: https://planet4589.org/space/misc/webb/time.html

⬐ ilyagr

This is very helpful. Looking at the table, my guess is that the scariest moments will be over by "launch +10 days". The sunshield is unfurled by "launch +8 days".

⬐ mabbo

Hard part is done- now for the really scary part.

Hundreds of deployment steps will follow. Each one has to go perfectly. If it doesn't, the JWST fails and tens of billions of dollars and 30 years wasted (by some definition of 'waste').

But for every single one of those steps, an incredible amount of work has been done to ensure that it cannot fail.

But if any step fails, there's no repair mission possible for at least a decade or more.

⬐ tzfld

Yes, somewhat stressful: "JWST has 344 single-point failures, 80% of which are in deployment systems"

⬐ C19is20

I said it on a different thread...why not build two (while they're at it)?

⬐ Grismar

Either it works and that would be a waste of additional billions, or it doesn't and there would be no guarantee the second wouldn't have the same critical mistake. This is not about rolling the dice, it's about putting every bit of effort and attention you can muster into one attempt - splitting that, even a little, reduces the odds of the main attempt working.

If it does end up failing, and let's pray to Bill's god and others it doesn't, we're better off trying something else in a few decades, or something simpler and more focused sooner.

⬐ garaetjjte

The big bang didn’t happen at any particular location. It happened everywhere all at once.

It's a giga-budget space telescope, mostly paid for by U.S. taxpayers. Most of whom are not nearly so interested in science geekery than the average HN'er. If it can be sold (as worth funding) to a bunch of the more-religious taxpayers as "a pilgrimage to discover and admire the handwork of God", or something similar, that's a plus in my book.

To my knowledge only the ten commandments are considered divinely dictated. The rest are written versions of oral histories, letters, and such by human authors.

⬐ dragonwriter

> To my knowledge only the ten commandments are considered divinely dictated

Both the entire text and the composition into the canon are pretty universally (within Christianity) considered divinely inspired (even by groups that disagree on what the entire text of the canon is.) The exact meaning of that inspiration and the degree to which it admits human error is...variable across different interpretations of Christianity.

The text of the decalogue as recorded—in more than one place, and not identically—in the Bible generally isn't considered any differently than the rest of the text. The text as it was inscribed on the stone tablets may be, but it's pretty clear that the human authors of the relevant Scripture didn't all correct their text with the tablets.

⬐ ALittleLight

Whether or not the text is "divinely inspired" is a different point than whether it is divinely dictated, which is what I was responding to. Of all the books of the Bible I can think of, none of them even claim to be divinely dictated - except for the ten commandments.

⬐ dragonwriter

> Whether or not the text is "divinely inspired" is a different point than whether it is divinely dictated

Thar actually depends rather strongly on whose understanding of divine inspiration you accept. While the term used is consistent, the range of beliefs as to what that term means is broad and extends the whole way to divine dictation.

> Of all the books of the Bible I can think of, none of them even claim to be divinely dictated - except for the ten commandments.

The decalogue isn't the only piece that claims to be directly quoting material that came directly from one or another person of the Trinity. (There's bits of the Creation story, the burning bush, and some other things scattered in the OT directly quoting the Father beyond the decalogue, and a whole lot of the NT directly quotes the Son.)

The decalogue is the only reference to a separate external document which was not merely divinely dictated by but written by the Hand of God, but it doesn't have any special claim of divine authorship beyond that of any of the other places God’s words in any form are quoted.

The 80% number is based on US taxpayer funding. For that to be true all Americans would have to be Christian, which they aren’t. This was my objection.

The difference between all Americans being Christian and some or even most of them being Christian is not “slight”.

80% and 63% are not close by any measure.

Qualifying the original statement with religious affiliation still ignores the fact that tax dollars are not paid with religious affiliation in mind and JWST has no (official) religious meaning. Further calling out American Christians but ignoring the Canadian and European Christians further distorts the 63% number.

This entire thread has been a textbook example of lying with statistics.

⬐ mulmen

I still disagree with the argument that the religious affiliation of those taxpayers deserves a specific callout rather than any other characteristic.

I also disagree with the initial characterization that all Americans are Christian. Or that Christian messaging is somehow “American”. It isn’t. It is a harmful stereotype.

JWST is not about religion. Defending the directors poor choice of message with religious statistics reduces both American Christians and Americans in general to oversimplified caricatures.

Christianity and the JWST have nothing to do with each other. To claim otherwise is insulting to both Americans and any contributors to the JWST, including the international community.

Saying JWST is funded 63% by Christians is false anyway, the other contributors also have some amount of Christian affiliation. Further, why choose the religious angle? Why not say it was half funded by women? Or by some ethnicity? Any way you apply these statistics is going to be insulting because they are irrelevant. This is why the directors messaging is problematic.

⬐ syshum

>>It isn’t. It is a harmful stereotype.

I dont see it has either a stereotype, nor harmful to acknowledge Christians in our society, or their contribution. In fact pretending they do not exist is IMO more harmful

>JWST is not about religion

I dont believe anyone claimed it was, nor did the NASA director. What you are attempting to do however is exclude any mentions of religion from the topic, I would not want to make JWST about religion, but I also have no desire to pretend religion does not exist, nor am I so fragile in my beliefs that someone else expressing theirs causes me consternation or an identity crisis like it seems to have done with you.

I recognize that it likely people of all religions have worked on some part of the JWST, I recognize that the current director of NASA is a christian, I can separate these thing in my mind, and believe that the director of NASA acknowledging his own religion in public does not paint either NASA nor the JWST program as "christian"

>>Christianity and the JWST have nothing to do with each other.

and this is where I believe you are wrong to a limited extent, in that religion is a part of the people that worked on JWST, all religions. As such all religions are a part of JWST just as people that do not believe in religion are a part of JWST. Denying this is to deny reality

>>Saying JWST is funded 63% by Christians is false anyway, the other contributors also have some amount of Christian affiliation.

Now you have moved the goal posts, I suspect because you know the foundation of our argumentation is sand that is quickly disappearing out from under you

The statement was limited to American's for which you took offense to what you believed was a statement implying all Americans where Christian, I then clarified the % of funding that could be attributed to American Christians, now you want to move the goal posts to talk about world wide christian contributions. I could do the math if you would like? not sure why that matters but...

>> Further, why choose the religious angle?

I did not choose it, I simply interjected facts into the conversation. I also interjected an opposing Agnostic position to that of Freedom From Religion Atheists that I have grown tired of over the years, something that has caused me to reject the label of "atheist" to describe myself because people that use this label themselves tend to be the most arrogant, toxic people proclaiming some level of moral and intellectual superiority over others. I would rather have a Jehovah Witness at my door telling me that I am going to Hell, than sit in a room with a Freedom From Religion Atheist complaining about some old guy saying "god Bless"

>>This is why the directors messaging is problematic.

Ohh Please, what is problematic is that fact that we have soo strayed away from the idea of Pluralism that people are sooo sensitive, that "political correctness" is soo run amok that we have to make a big deal about some one saying "God Bless" something...

This is not a contribution by Christians the contributions are by taxpayers. Their religious affiliation is irrelevant. In a secular nation like the United States it is inappropriate to conflate the two.

I believe the discussion originated, though, in justification of why a speech at the launch might quote from the literary tradition shared by Christians and people with close societal connections to Christians.

The NASA administrator is a political appointee, so they will be as religious as the president wants (or allows) them to be. Positions like these are sometimes given as reward for loyal party members who supported the president’s election campaign rather than the most qualified candidate.

However, Bill Nelson is an astronaut so he probably is the most qualified (politician) for the job. I’m sure he works hard to get NASA the funding it needs regardless of his personal beliefs (and it would be illegal to make atheism a job requirement). Aside from awkward speech giving I think most people are optimistic about how he’ll do as administrator.

⬐ reportingsjr

Calling Bill Nelson qualified since he is an astronaut is hilarious to read.

Consider that the other, legitimately qualified people on that mission gave him the nickname "ballast" and it is widely regarded that the only reason he went up is by strong arming his way in since he had a powerful congressional position.

He is not considered a great NASA admin and it was pretty disappointing when he was chosen.

It may be confusing because of the attitude toward empirical science of some prominent strains of American fundamentalism (and the way the media often reduces that to a narrative of a fundamental religion vs. science conflict), but having religious belief about the metaphysical nature of reality and pursuing scientific understanding of its physical nature have often been things that go together.

Being a scientist and being religious are not mutually exclusive.

True, but the intersection of the Venn diagram has only shrunk throughout history.

Oppenheimer quoted the Baghavad Ghita in his first statement after the Trinity test. Scientists are humans too.

There is a ton of wisdom in the Gita.

⬐ HideousKojima

I've read the Bhagavad Gita and it spends a significant amount of time talking about karma and reincarnation. Not sure how you could see it as non-religious unless you did to it what Thomas Jefferson did to the Bible.

⬐ cscurmudgeon

There is a lot of non religious content in there.

https://michaeldevfay.medium.com/the-bhagavad-gita-for-athei...

The point of Gita's message is to NOT worry about karma and reincarnation.

⬐ HideousKojima

And there's plenty of non-religious content in the Bible, but no one in their right mind would call it a non-religious text.

⬐ avar

That famous Oppenheimer quote is from 1965, not 1945.

After the Trinity test he went on to work for the US government for some years on nuclear weapons, which goes against the usual "what have we done?" sentiment that quote is meant to convey.

You'd be surprised how many scientists throughout history were motivated by the notion of better knowing the nature of god.

> But still, I cannot believe that people who are supposedly scientists start quoting the bible when they are themselves involved in maybe one of the greatest scientific achievements of our time. How does that resolve?

As atheist: even if you don’t believe in christianity, the bible is still a book with some stories that have made a massive impact and which can evoke deep emotion in many readers/listeners. Especially in such an emotional context as venturing out into space.

⬐ Grismar

The same would be true for the Torah, Quran or any other major religious text (including non-Abrahamitic ones) - would you have brought the same defense, if only one of those had been quoted, if you are perfectly honest?

⬐ jbay808

The Book of Genesis is from the Torah though, isn't it?

⬐ kuschku

Genesis is common to all abrahamistic religions, so it has the widest appeal.

Personally I’d have appreciated a quote from any other text equally, but I’m going to assume that a US government official reading a non-christian text publicly might have effects on coming elections.

⬐ atonse

I’m a pretty strong atheist. It’s odd to me too. However I’m answering why the Bible over other religious texts. That one at least feels obvious.

The people reading it were likely Christian. The majority of the people listening would’ve been Christian. The majority of the people that footed the bill would’ve been Christian.

Like others have said, you don’t have to believe in the existence of a diety to feel moved by words from some religious texts.

When they made the choice of rocket, Ariane 5 was the most reliable rocket in the world that was capable of lifting it. Given the sticker price, they decided that cutting risk was more important than purchasing domestic.

⬐ perihelions

It was far from the "most reliable" when this decision was made!

>"Faced with a grim record of 4 failures from just 14 Ariane 5 launches, some observers were starting to ask if Europe's 25-year-old rocket programme is more trouble than it's worth."

4 failures in the first 6 years of operation, and only 1 in the following 20 years is a good track record. How were the other launch vehicles faring in 2002?

Naive Q: what makes Ariane 5 better than Falcon 9/Heavy here?

⬐ robin_reala

Falcon didn’t exist when the choice was made, which makes Ariane automatically better.

It existed and was already a reliable launch vehicle when the project was being designed and constructed.

The JWST project started 6 years before SpaceX was even founded. The telescope was tailor made to be carried by the most capable rocket at the time: Ariane 5.

⬐ gameswithgo

80 something flawless launches in a row

⬐ WJW

Falcon 9 does not have enough capacity; the JWST is too heavy for it to launch all the way to L2. So F9 is out.

Falcon Heavy does have enough capacity, but:

1. It was not really available for bookings when the JWST mission was planned and

2. even if NASA could choose again today, Ariane 5 has a track record of 106 successes out of 111 launches (107 out of 112 now I guess) and Falcon Heavy is still relatively untested with only 3 launches (all of which were successful, but still only 3). For something super critical you might want to go with old but dependable technology over the newest hotness.

⬐ inglor_cz

You are being downvoted, possibly for sounding vaguely nationalistic, but this is actually a good opportunity to ponder the timescale of the entire program.

The idea of JWST was conceived around 1990, when Hubble was freshly flown into space and people started thinking about its successor. Development in earnest started in 1996 and JWST should have been ready to launch in 2007. This date was pushed back many, many times. (Much like with construction of nuclear power plants - megaengineering projects tend to suffer from this kind of slip-ups, cost overruns and delays.)

This means that the definite launch arrangements were done before SpaceX was the giant it is today. Space Shuttle was discontinued, so the most reliable rocket of that time simply won. This is no ordinary payload and you really do not want to lose it to launcher failure.

⬐ thebigman433

Even if they were going to pick a launcher today, the Ariane 5 would still probably be the choice. F9 cant get JWST to where it needs to go, and Falcon Heavy is still new and relatively unproven with only 3 launches. There really arent any other good choices for it

⬐ cletus

I got up this morning to watch the launch. I’m used to seeing the pageantry and showmanship of a SpaceX launch and I was left… underwhelmed.

Don’t get me wrong: this is a mold-boggling complex device and launch. It’s an amazing technical feat.

But YouTube had a 720p stream. There was pretty limited video. After a few seconds it was above the clouds and lost to view so we were just watching animations.

Compare this to the first Falcon Heavy Launch. Synchronized booster landings. video from the Launch vehicle and of course Starman in the Tesla.

Say what you will about Elon, he can put on a show.

Anyway, I really hope the JWST well. There is still a ton to do and a ton that can go wrong in the coming months. The Launch is a massive milestone. Fingers crossed.

This is ridiculous. This telescope is not a show, it is made for science, and they have made the right priorities by not spending on entertainment value.

⬐ chrsig

I appreciate the sentiment here. If I may offer a different perspective: the public has paid a _lot_ of money for this thing, and getting a good stream of the launch set up (seems like it should be) a drop in the bucket. I don't think it'd be a wasted effort -- getting and keeping people interested and engaged with space science is a worthy endeavor

⬐ 1_player

They used taxpayers money to build the thing, which means they've left aside just enough for a barebones show, and hopefully every last dime has been invested in the project, and that is exactly how it should be.

If you spend more on marketing, you spend less on science. It's called a "budget".

⬐ chrsig

By keeping taxpayers engaged, they'll hopefully be more willing to provide a bigger budget in the future.

SpaceX launch broadcasts have much higher production quality and have video from on-board the rocket after ground tracking loses sight of it which is what the grandparent is referring to.

⬐ mortehu

If people are awed, I doubt this is caused by the production value of the video stream though.

It is likely that "production value" is negatively correlated with actual value.

The SpaceX launches broadcasts are made for largely uneducated lay people. No one should be entertained by that. They all feel like infomercials.

Elegant I agree, but a failure in readability.

- Nova+Mono is the wrong font for a display like this.

- Those characters in very light gray make incredibly difficult to read and contrast specially at the bottom part of the display were they just fade into the dark the blue background.

Notice the difference and much better result, with the color choice for characters in the James Webb pages posted above.

Yes, I agree that readability could have been better.

⬐ mendigou

This is very obviously designed with some nostalgic/artistic intention. Spacecraft operations displays use fonts similar to those and they are perfectly readable (they do use different colors though).

It also seems to me that the faded out section at the bottom is like that because none of the stations are online with the spacecraft.
