It is a bit chilling to watch these astronaut profiles having just read yesterday about the heat shield issues observed on the prior mission, and that this will be the first time we can test the heat shield in the actual pressures and temperatures that it will have to endure.
Even though you could question the whole Artemis concept, it's still extremely exciting watching the countdown with my son. I just missed the original Apollo flights and had assumed I would never see a moon landing in my lifetime. We may well not have a landing for quite some time yet, but it's still cool to see a Moon bound rocket standing on the launchpad...
I don't know if it's feasible for you, but if you can, try to take your kid to see a live rocket launch. The TV is grossly unable to display how awesome these things are in person.
It is one of the things I regret not ever getting to see a shuttle launch. The closest I ever got was when I flew over Florida while a shuttle was on the pad.
I lived in Port Orange FL until i was 12, during night launches my dad would take the family to New Smyrna Beach or some where a short drive South where we watched the shuttles come up over the water somehow. I can't remember the details it was a lonnnng time ago haha. I do remember the launches sounding like popcorn popping.
I live in Dallas now and will be turning 50 soon, i want to catch the next Starship launch live but would have to time it perfectly to get time off of work ahead of time.
It's even more exciting when you realize that the last crewed mission beyond Low Earth Orbit was 1972 and each person on that spacecraft today are younger than that.
There is a LOC (Loss of Crew) number that is typically calculated for these missions. I'm curious what that is? Early Apollo missions were on the order of 4%.
Before the Apollo launch, von Braun was asked what the reliability of the rocket was. He asked 6 of his lieutenants if it was ready to fly. Each replied "nein". Von Braun reported that it had six nines of reliability.
The joke that made the rounds of NASA was that the Saturn V had a reliability rating of .9999. In the story, a group from headquarters goes down to Marshall and asks Wernher von Braun how reliable the Saturn is going to be. Von Braun turns to four of his lieutenants and asks, "Is there any reason why it won't work?" to which they answer: "Nein." "Nein." "Nein." "Nein." Von Braun then says to the men from headquarters, "Gentlemen, I have a reliability of four nines."
In 2014 an independent safety panel estimated 1:75, but I think it's slightly better now. The shuttle program officially had a limit of 1:90 but in practice achieved 1:67.
Out of curiosity, why do you see this as a worthwhile endeavor?
My personal perspective is that the resources are better used for other purposes, but it's possible that I just haven't encountered some compelling reason yet.
Do you watch sports, football, the Olympics? If not I'm sure you know someone who does. Same category as this. Each of the 32 NFL team is worth about the cost of 1-2 Artemis launches. The entire league could fund the whole Artemis program nearly twice. Hosting the Olympics is worth about 3-10 launches.
Like sports, the objective is ultimately useless except as a showcase of what humanity has to offer, and people like to see that.
Even if you think Space travel is worth the money (which I personally do), adding humans to the mix makes projects incredibly more expensive. Even in the realm of space travel and research, sending humans is a questionable use of the money.
I think there is a major difference though. Sports events are not pretending to be anything else. The Artemis mission claims to be advancing science and claims to be a stepping stone for an eventual moon base and a manned mission to Mars. I personally have serious questions about all of these.
The fact that we hope to get some new tech with this whereas sports aims for nothing is just icing on the cake. I think big space missions are worth it every now and then on a humanitarian level; even if no new discoveries are made, a new generation of engineers will become fluent in what we have already discovered. Humanity's education is not "done" when the last fact is written in a book, it needs to be constantly refreshed or it will disappear.
Even in sports you do not get "nothing", it has certainty helped advance the field of medicine.
Do you really disagree that it’s advancing science? Surely actually testing hardware, building knowledge on how to run this type of mission, learning to use lunar resources, figuring out how to keep people alive, etc. will teach us things we couldn’t learn any other way.
Fwiw do share your concerns about the methods (sending humans on this specific mission is questionable, SLS is questionable compared to SpaceX approach).
Whether a moon base is needed or even beneficial is a question I have not heard a convincing answer in favor. And even if moon base is indeed needed and/or beneficial to future space exploration / resource extraction why robots cannot more efficiently build (or assemble) such a moon base is another question I need an answer to.
We are sending humans to (or around) the moon now, but it may just turn out to be a wasted effort, done solely for the opulence (or more cynically bragging rights / nationalist propaganda).
> My personal perspective is that the resources are better used for other purposes, but it's possible that I just haven't encountered some compelling reason yet.
Well, people are often obsessed with rationality, and seek reasons to do something, but there is one reason that works almost for anything: just because. If we want to go forward, we'd better try a lot of things, including those that do not look very promising. We don't know the future, the only way to uncover it is to try. Did you hear about gradient descent? It is an algo for finding local maxima and to do its work it needs to calculate partial derivatives to choose where to go next. In reality doing things and measuring things are sometimes indistinguishable. So society would better try to move in all directions at once.
A lot of people believe that to fly to the Moon is a good idea. Maybe they believe it due to emotional reasons, but it is good enough for me, because it allows to concentrate enough resources to do it.
> the resources are better used for other purposes
It is much better use for $$$ than the war with Iran. I believe that the war have eaten more then Artemis already, and... Voltaire said "perfect is an enemy of good". The Moon maybe not the perfect way to use resources, but it is good at least.
This argument comes up a lot, about whether a space program is “worth it” in some sense. One problem I’ve found is that these discussions often treat this in the abstract. And then we get into the nature of human endeavor, the economic benefits of that R&D, etc.
Let’s talk about this in terms of practicalities. The NASA budget for 2026, per Wikipedia, is $24.4B. I often find it hard to really reason about the size of federal budgets, and the impact on tax payers, but I have a thought experiment that I think helps put it into perspective. Suppose we decided to pay for the NASA budget with a new tax, just for funding NASA. And we did that in the simplest (and most unfair) possible way: a flat rate. Every working adult in the US has to pay some fixed monthly rate (so excluding children and retirees). Again, per Wikipedia, that’s around 170M people. Take the NASA budget, divide by 170M, and you get … $11.96/month.
Obviously, there’s lots of flaws in this. That’s not we pay for NASA, we have income tax as a percentage with different tax brackets. But it is a helpful way to frame how much a country is spending, normalized by population. And I think it puts a lot of things in perspective. $11.96/month is comparable to a streaming service. And we talk a lot about whether NASAs budget is better used for other purposes, but we don’t do the same thing for a streaming service.
Hell, look at US consumer spending: https://www.bls.gov/news.release/cesan.nr0.htm (note that that spending is in dollars per “consumer unit,” which is I think is equivalent to an adult US worker, but there might be some caveats). Based on that, the average US consumer spends around $26.17/month on “tobacco products and smoking supplies”. I just feel it’s a little silly to worry about the NASA budget when the US consumer spends twice that on what is objectively a luxury good. At least NASA won’t give you cancer.
> Out of curiosity, why do you see this as a worthwhile endeavor?
to me it's inspiring and gives people something to cheer for. It also keeps a lot of people employed, productive, and at least has the possibility for new innovation. When looking at the mountains and mountains of wasted taxpayer dollars I dislike these the least.
The moonshot is a halo program that, when executed in a non-profit form, ends up benefiting society as a whole due to smart people being cornered and forced to solve hard problems that typically have applicability elsewhere on Earth.
Edit: remember the Kennedy speech — We choose to go to the moon not because it is easy, but because we thought it would be easy.
I want humanity to continue to be explorers. The Moon is a good next thing, then asteroid mining, humans on Mars and Venus, and eventually colonizing the Milky Way.
Because it is good for humans to have a thing to do. Not sure why this is not considered a valid reason. A lot of these 'it would be better to do X' assumes everyone has the same psychological profile as you. They don't. Many people are driven to explore and would go mad otherwise.
It's quite telling that all the replies you're getting are about "hope" and "jobs" with no actual scientific reason. I guess we're taxing people for vanity space missions and jobs programs. Makes sense.
I do much better with things to look forward to, or when I have a feeling that progress can be made. An interesting movie coming out, new music coming out. Or even better reminding me what humans are capable of above just grinding to get by or grinding to exploit others. Haven't been many moments of feeling progress lately.
Hopefully, in a few years we will figure out that hydrogen rockets can not reliably launch on time and we'll switch to less leaky fuels. Then maybe we won't need to pull 40 year old engines out of museums to dump in the ocean.
I'm all for human spaceflight, but the Senate Launch System seems the best argument for shutting down human spaceflight programs.
Well, we should have figured that out with the STS. That's what the STS was for - figuring out what technologies made for inexpensive, rapid spaceflight and which technologies don't.
Then the senate mandates the new rocket to use specifically the most expensive, problematic, least reliable technology. Completely designed to fail.
I tuned in for 60 seconds, the presenter got everything wrong, and I just tuned out until liftoff.
She called the top of the ET (well, it's no longer an ET, but it's the stage that was the STS ET) the "upper stage". She said that the propellents are stored at thousands of degrees below zero. And so on. This is a NASA presenter?
> She called the top of the ET (well, it's no longer an ET, but it's the stage that was the STS ET) the "upper stage". She said that the propellents are stored at thousands of degrees below zero. And so on. This is a NASA presenter?
To be fair to her, she seemed to explicitly refer to what sits on top of the core stage, it just wasn't in the diagram she was gesturing to the top of at the time.
To be fair to you, I think the cryogenic comment was worse and she actually said "thousands of degrees below Fahrenheit".
The problem is they're trying to run hours of programming leading up to this launch for some reason, but aren't willing to force the experts to come in to do the commentary. They should have given her a script.
You are not the target audience for this sort of presentation. Media directed at the laity is more about being directionally than quantifiably correct, and is full of metaphor and embellishment to capture the imagination rather than communicate something with precision.
People who want the actual details and numbers will read.
I'm just SO HAPPY we can talk about something that doesn't involve the Iran war, ICE etc. This is a really historic moment, I hope that the current and future administrations continue investing in space exploration. I've waited my whole life for this as the entire "action" happened before I was born. Hubble/James Webb/ISS are cool but Artemis is something else!
Really hoping those of us who think NASA has jumped the shark won't have to keep ourselves from saying "I told you so" next week out of respect for the dead.
This is four people putting their lives at risk for poor engineering and bad project management.
The "right stuff" applies to the engineers too, but they've all unfortunately left Boeing and NASA.
This opinion may be unpopular here but it's hard to get excited about a colossal waste of taxpayer money after all the damage DOGE did. I don't understand how these NASA missions with questionable scientific value and obscene budgets get off the ground.
I mean I do understand, NASA funding is important to oligarchs. But still.
I personally find the grind easier when there also big things happening. You can't just cook the same, most basic, cheapest meal every day for your family and expect them to be happy. Who wants to join a club that doesn't do anything interesting? Same with society. It sometimes needs to dream, to aspire and inspire. To lift peoples head from the toil and look up.
Artemis was already set in stone well before DOGE came about and IMO if the federal government is going to set mountains of cash on fire I'd rather it be to NASA than half the crap the government wastes every year.
It is a bit chilling to watch these astronaut profiles having just read yesterday about the heat shield issues observed on the prior mission, and that this will be the first time we can test the heat shield in the actual pressures and temperatures that it will have to endure.
Godspeed crew of Artemis II.
That was the intent of the piece. It is impossible to assess the true intent of such a piece when it so blatantly is asking for attention.
Some people are great at self promotion.

It's even more exciting when you realize that the last crewed mission beyond Low Earth Orbit was 1972 and each person on that spacecraft today are younger than that.
Fingers crossed that this https://idlewords.com/2026/03/artemis_ii_is_not_safe_to_fly.... doesn't have any effect.

After the moon landing, Armstrong allowed that he had estimated the survivability at 50%.
The official minimum standard is 1:270
Hilarious!
It's been 54 years since humans last visited the Moon. Hopefully, in a few years we will get boots back on the surface.

I don’t have any questions about a mission to Mars, it is a stupid and pointless trip that I don’t want to ask any questions about.
The Moon, I dunno, it’s at least in Earth’s gravity well so it isn’t like we’re going totally the wrong direction when we go there, right?
At best it could be a gas station on the trip to somewhere interesting like the Asteroid belt, though.
Whether a moon base is needed or even beneficial is a question I have not heard a convincing answer in favor. And even if moon base is indeed needed and/or beneficial to future space exploration / resource extraction why robots cannot more efficiently build (or assemble) such a moon base is another question I need an answer to.

Successful space travel is one of the few big news events where nobody has to be unhappy.
Most of the other big news events are ones where people get severely hurt, and political ones where one partly loses.
With this, we can look up at the moon, and say "Humanity did that."

For-profits are of no benefit to society? Are SpaceX rockets a loser for society?
It encourages kids to study science.
It unites Americans towards a cause.
The engineering advancements have commercial applications.
And at the most basic level, it's a jobs program. Look at how many Americans are working because of this.
Go take a look at how much this costs compared to the rest of the federal budget. I think you'll be surprised by how little money NASA gets.
Now, the military...
I want humanity to continue to be explorers. The Moon is a good next thing, then asteroid mining, humans on Mars and Venus, and eventually colonizing the Milky Way.
How many days of a war with Iran could be funded with the Artemis budget?
Because inevitably the Earth will have yet another ELE. And it's a better use of tax dollars than warmongering, YMMV.
Think of all that cheese.
Because it is good for humans to have a thing to do. Not sure why this is not considered a valid reason. A lot of these 'it would be better to do X' assumes everyone has the same psychological profile as you. They don't. Many people are driven to explore and would go mad otherwise.

Oh, don't worry, we did figure that out. What we haven't figured out yet is how to stop Congress from involving themselves in engineering decisions.

Then the senate mandates the new rocket to use specifically the most expensive, problematic, least reliable technology. Completely designed to fail.
Have such hopes for the Starship.
Safe trip to the crew. I do hope that they have ironed out all the issues.

The experience of hearing factual things presented with passion and obvious expertise is in itself inspiring. Why settle for less?
Bring back John Insprucker.
I for one am begging God that this is merely April fools all the way down.
i'm sure the whole talk track was piped through an AI for clarity and excitement and the presenters were told to read the script.
There is also a stream on ESA Web TV https://watch.esa.int/
Gonna watch with my son if it doesn’t get postponed.

You better run over there and let them know.

predicting malfunctioning systems (just a guess)
polymarket or gtfo :)
My opinion is 60/40 in favor of launch today. It's not unusual at all for something to come up in the final 10-30 minutes.
Kalshi is more optimistic. https://kalshi.com/markets/kxartemisii/artemis-ii-launch-dat...
